Description

  The present invention relates to a system for separating and air-conditioning a non-smoking room and a smoking room provided adjacent to each other.

Prevention of passive smoking is required by the Health Promotion Act. In order to prevent passive smoking, the `` Guidelines for Smoking Control in the Workplace '' issued by the Ministry of Health, Labor and Welfare has a large air volume ventilation system that keeps the dust concentration at 0.15 mg / m ³ or less, and at the entrance and exit of the smoking room There is a need for smoke distribution with a smoking room where the airflow toward the air can be kept above 0.2m / s.

However, according to SHASE-102-2010 of the Society for Air Conditioning and Sanitary Engineering, the basic required ventilation for cigarettes satisfying a dust concentration of 0.15 mg / m ³ is as large as 130 m ³ / line, and the wind speed of the opening is 0.2 m / s. In order to secure the above, a great amount of displacement is required. The reality is that most smoking rooms do not satisfy the required functions due to structural limitations of the building. In addition, it is pointed out that although an air conditioner is necessary to maintain the thermal environment of the smoking room, cigarette smoke that has risen due to the air flow of the air conditioner is diffused to the smoker, resulting in a poor environment. Yes. When a large-capacity exhaust device can be installed, a large amount of air-conditioned room air is discharged outdoors, which increases running costs. The measures for preventing passive smoking are technical issues such as prevention of passive smoking, reduction of ventilation airflow, improvement of comfort and improvement of energy saving.

  Here, Patent Document 1 discloses a technique for air-conditioning a smoking room by a replacement ventilation system or an underfloor ventilation system. In this technology, when the height of the room is on the horizontal axis and the temperature is on the vertical axis, the temperature distribution is controlled to a straight or downward convex shape, so that smoke that has risen to the vicinity of the ceiling does not fall again into the living area. I'm letting

  Patent Document 2 discloses a technique for forming an air flow from a non-smoking area to a smoking area through a passage by returning air in the smoking area to the non-smoking area by a reflux element in the non-smoking area and the smoking area partitioned by the partition. Is disclosed.

WO2009 / 131157 WO2013 / 137417

  However, the technology of Patent Document 1 is exclusively related to air-conditioning a smoking room, and does not take into account the fact that the non-smoking room and the smoking room provided adjacent to each other are smoked and air-conditioned. On the other hand, in the technique of Patent Document 2, the smoking area and the smoking area are divided, but the air in the smoking area is blown downward from the ceiling portion of the smoking area. For this reason, the inside of the smoking area is not replaced with ventilation, and the smoke accumulated above the room is agitated and may fall again into the living area. Further, the reflux element as disclosed in Patent Document 2 has a problem that chemical substances for smoking cannot be collected and smoking is insufficient. Further, the configuration of the reflux element disclosed in Patent Document 2 is large, and it is difficult to repair the existing building.

An air supply port may be provided, and an exhaust duct that exhausts the air exhausted from the upper part of the smoking room to the outside may be provided.

  Further, according to the present invention, there is provided a method for operating these smoke separation air-conditioning systems, including a non-use mode of the smoking room, a non-smoking mode of the smoking room, a smoking mode of the smoking room, and an open mode of the door. There are four operation modes, and the amount of exhaust from the smoking room excluding those that are subject to return air is the non-use mode of the smoking room ≦ the non-smoking mode of the smoking room <the smoking mode of the smoking room ≦ the above There is provided a method of operating a smoke separation air conditioning system, characterized in that the number of door opening modes increases in order.

  Further, according to the present invention, the operation method of these smoke separation air conditioning systems is such that when the door is closed, the air exhausted from the upper part of the non-smoking room and the outside air are made into low-temperature air and the lower part of the non-smoking room. A portion of the air exhausted from the upper part of the smoking room and the outside air is supplied to the lower part of the smoking room as low-temperature air, and the remaining part of the air exhausted from the upper part of the smoking room is exposed to the outside When exhausted and the door is opened, air and outside air exhausted from the upper part of the non-smoking room is supplied to the lower part of the non-smoking room as low-temperature air, and the intake of outside air into the smoking room is stopped, A part of the air exhausted from the upper part of the smoking room is converted into low-temperature air and supplied to the lower part of the smoking room, and the remaining part of the air exhausted from the upper part of the smoking room is exhausted to the outside. An operation method of the smoke separation air conditioning system is provided. In addition, when the door is closed and only the non-smoking room is air-conditioned, low-temperature air is supplied to the lower part of the non-smoking room and low-temperature air is supplied to the smoking room. Without making the smoking room more negative than the non-smoking room, the door is closed and the non-smoking room and the smoking room are air-conditioned, but when smoking is not performed in the smoking room, Supply low temperature air to the lower part and the lower part of the smoking room, make the non-smoking room have a negative pressure than the smoking room, close the door, air-condition the non-smoking room and the smoking room, and smoke in the smoking room When performed, low temperature air is supplied to the lower part of the non-smoking room and the lower part of the smoking room, the smoking room is set to a negative pressure than the non-smoking room, and when the door is opened, the lower part of the non-smoking room Low temperature air is supplied to the smoking room, and low temperature air is not supplied to the smoking room. Characterized by a negative pressure than non smoking rooms, operating method of the smoke separation air conditioning system is provided. In this case, a surplus exhaust duct and a cigarette smoke exhaust duct for exhausting the air exhausted from the upper part of the smoking room to the outside are provided, the door is closed, and only the non-smoking room is air-conditioned, and the door is closed. The non-smoking room and the smoking room are air-conditioned, but when smoking is not performed in the smoking room, the exhaust is performed only by the excess exhaust duct, the door is closed, and the non-smoking room and the smoking room are air-conditioned. Then, when smoking is performed in the smoking room and when the door is opened, the excess exhaust duct and the cigarette smoke exhaust duct may be used to exhaust air.

  In the smoke separation air conditioning system and the operating method thereof according to the present invention, ventilation by stratified air conditioning is performed by, for example, replacement ventilation or floor blowing type air conditioning.

  According to the present invention, it is possible to improve the ventilation efficiency of a smoking room and realize a comfortable smoking environment, and at the same time, eliminate smoke from flowing into the non-smoking room. By ventilating the non-smoking room and the smoking room with the stratified air conditioning, the indoor air can be kept clean while improving the ventilation efficiency without diffusing the cigarette smoke by the blowing airflow. By performing stratified air conditioning, the operating power cost can be reduced and energy can be saved compared to mixed air conditioning, and the equipment cost can be reduced because the material is saved. Also, when the door is opened, the amount of air supplied to the smoking room is reduced compared to when the door is closed, or the supply of air to the smoking room is stopped, so that the non-smoking room is changed to the smoking room. The amount of air to go increases, and air from the smoking room to the non-smoking room can be prevented from leaking through the open door. Furthermore, since the non-smoking room and the smoking room are provided adjacent to each other, restrictions on the layout of the room are eased.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. In the present specification and drawings, elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  First, with reference to FIGS. 1 and 2, a smoke distribution air conditioning system 1 according to an embodiment of the present invention applied to replacement ventilation will be described. A non-smoking room 10 and a smoking room 11 are provided adjacent to each other. In addition, a wall 13 that partitions the non-smoking room 10 and the smoking room 11 is provided with a door 13 that allows the non-smoking room 10 and the smoking room 11 to communicate with each other. FIG. 1 shows a state where the door 13 is closed, and FIG. 2 shows a state where the door 13 is opened.

  Further, the wall surface 12 is provided with an opening 15 that allows the non-smoking room 10 and the smoking room 11 to communicate with each other at a position above the living areas 20 and 40 described later. In the illustrated form, an opening 15 is formed at the upper end of the door 13. In a state where the door 13 is closed as shown in FIG. 1, air enters the smoking room 11 from the non-smoking room 10 through the opening 15 at a position above the living areas 20 and 40. The entry of air from the non-smoking room 10 to the smoking room 11 is caused by a difference in the supply / exhaust amount of the non-smoking room 10 and the smoking room 11. In other words, this is achieved by room pressure control in which the non-smoking room 10 is always maintained at a higher pressure than the smoking room 11. The opening 15 may be a complete opening, but an upward louver, or a louver that stands up from the non-smoking room 10 to the smoking room 11, is provided in the opening 15, so that tobacco smoke is transferred from the smoking room 11 to the non-smoking room 10. It is good also as a structure which prevents entering in. The position of the opening 15 may be higher than the living areas 20 and 40 and higher than the respirators of the standing humans 21 and 41.

  The wall surface 12 is provided with a door switch 16 that detects opening and closing of the door 13. An opening / closing signal of the door 13 detected by the door switch 16 is input to the control unit 17.

  For example, a human 21 exists as a heating element in the living area 20 formed in the lower part of the non-smoking room 10. An air supply unit 22 is provided at a lower portion of one side surface in the non-smoking room 10 (the left side surface in the non-smoking room 10 in the drawing). The air supply unit 22 and the air supply unit 42 to be described later may be, for example, the “air supply unit 20” shown in Japanese Patent No. 4006196, or the “air diffusion port 1b” shown in, for example, Japanese Patent No. 2862149. May be used. Further, an exhaust port 23 is provided on the ceiling surface of the non-smoking room 10.

  The air supply unit 22 is supplied with low-temperature air SA produced by the air conditioner 25 via the air supply duct 26. The air conditioner 25 is a temperature control means for the non-smoking room 10 and includes a cooling coil 27 and a fan 28. An outside air duct 30 and a return air duct 31 are connected to the air conditioner 25, and the outside air OA is introduced into the air conditioner 25 through the outside air duct 30, and the non-smoking room 10 discharged from the exhaust port 23 through the return air duct 31. Return air RA from the inside is introduced into the air conditioner 25. A motor damper 32 is attached to the outside air duct 30, and similarly, a motor damper 33 is attached to the return air duct 31. The opening degree of these motor dampers 32 and 33 is adjusted by the control unit 17, and the amount of outside air OA and the amount of return air RA introduced into the air conditioner 25 are controlled.

  Similar to the non-smoking room 10, for example, a human 41 is present as a heating element in the living area 40 formed in the lower interior of the smoking room 11. An air supply unit 42 is provided at the lower part of one side surface in the smoking room 11 (the right side surface in the smoking room 11 in the drawing). In addition, two exhaust ports 43 and 44 are provided on the ceiling surface of the smoking room 11.

  The air supply unit 42 is supplied with low-temperature air SA produced by the air conditioner 45 via the air supply duct 46. The air conditioner 45 is a temperature control means for the smoking room 11 and includes a dust collection filter 47 such as an electric dust collector, a cooling coil 48 and a fan 49. A branch outside air duct 50 (outside air duct) and a return air duct 51 are connected to the air conditioner 45, and outside air OA is introduced into the air conditioner 45 through the outside air duct 30 and the branch outside air duct 50. The return air RA from the inside of the smoking room 11 discharged from one exhaust port 43 is introduced into the air conditioner 45. A motor damper 52 is attached to the branch outside air duct 50, and similarly, a motor damper 53 is attached to the return air duct 51. The opening degree of the motor dampers 52 and 53 is adjusted by the control unit 17 so that the amount of outside air OA and the amount of return air RA introduced into the air conditioner 45 are controlled.

  An exhaust duct 55 is connected to the other exhaust port 44, and an exhaust fan 56 is attached to the exhaust duct 55. By the operation of the exhaust fan 56, the air in the smoking room 11 is exhausted EA to the outside.

  In the smoke separation air conditioning system 1 configured as described above, the low temperature air SA produced by the air conditioner 25 is supplied from the air supply duct 26 and the air supply unit 22 by the operation of the fan 28 ( (Not shown) is supplied to the lower part of the non-smoking room 10. The low-temperature air SA supplied into the non-smoking room 10 is described in, for example, the above-mentioned Patent No. 4006196 and Patent No. 2862149 due to the temperature difference between the thermal load caused by the human 21 and the low-temperature air SA. It is supplied with wind speed to form replacement ventilation, which encourages upward movement of room air. Thus, the living area 20 below the non-smoking room 10 is filled with the low-temperature air SA at a low speed, and the living area 20 is maintained in a comfortable environment.

  That is, since the living area 20 in the non-smoking room 10 includes a human 21 or the like as a heating element, it is supplied to the living area 20 in the non-smoking room 10 to heat the human 21 or other heat generating devices. The low-temperature air SA that has contacted the target is eventually heated and gradually rises. Due to the upward flow, contaminants such as dust and gas generated around the person 20 in the living area 20 in the non-smoking room 10 can be conveyed upward in the non-smoking room 10.

  As a result, the air accumulated in the upper part of the non-smoking room 10 (heated air) is not agitated, that is, disturbs the temperature stratification of the living area 20 where the human 21 in the non-smoking room 10 stands upright. Absent. The air can be reintroduced into the air conditioner 25 through the exhaust port 23 and the return air duct 31. In the air conditioner 25, the return air RA introduced through the return air duct 31 and the outside air OA introduced through the outside air duct 30 are cooled together by the cooling coil 27 and become low-temperature air SA by the power of the fan 28. The air is supplied from the air supply duct 26 and the air supply unit 22 to the lower part of the non-smoking room 10 through an air supply port (not shown). In this way, while supplying the low-temperature air SA to the living area 20 below the non-smoking room 10, the inside of the non-smoking room 10 is stratified air-conditioning by exhausting contaminants such as dust and gas from the upper part of the non-smoking room 10 together with heated air. In this embodiment, ventilation by replacement ventilation is performed, and the living area 20 below the non-smoking room 10 is maintained in an environment of clean low-temperature air SA.

  Similarly, the low-temperature air SA produced by the air conditioner 45 is supplied to the lower part of the smoking room 11 from the air supply duct 46 and the air supply unit 42 through the air supply port (not shown) by the operation of the fan 49. The The low-temperature air SA supplied into the smoking room 11 is described in, for example, the above-mentioned Patent No. 4006196 and Patent No. 2862149 due to the temperature difference between the thermal load caused by the human 41 and the low-temperature air SA. It is supplied with wind speed to form replacement ventilation, which encourages upward movement of room air. Thus, the living area 40 below the smoking room 11 is filled with the low-temperature air SA at a low speed, and the living area 40 is maintained in a comfortable environment.

  That is, since a human 41 or the like as a heating element is also present in the living area 40 in the smoking room 11, it is supplied to the living area 40 in the smoking room 11 to heat the human 41 or other heat generating devices. The low-temperature air SA that has contacted the target is eventually heated and gradually rises. Due to the upward flow, pollutants such as dust and gas generated around the person 40 in the living area 40 in the smoking room 11 and cigarette smoke generated by smoking can be conveyed upward in the smoking room 11.

  As a result, the air accumulated in the upper part of the smoking room 11 (heated air) is not agitated, that is, disturbs the temperature stratification of the living area 40 where the human 41 in the smoking room 11 stands upright. Absent. In addition, a part of this air can be reintroduced into the air conditioner 45 through the exhaust port 43 and the return air duct 51. Further, the remaining part of the air accumulated in the upper portion of the smoking room 11 is exhausted EA to the outside through the exhaust port 44 and the exhaust duct 55 by the operation of the exhaust fan 56. In the air conditioner 45, the return air RA introduced through the return air duct 51 and the outside air OA introduced through the outside air duct 30 and the branch outside air duct 50 are filtered together by the dust collection filter 47, and then the cooling coil 48. Then, the air is cooled and becomes low-temperature air SA, and is supplied to the lower part of the smoking room 11 from the air supply duct 46 and the air supply unit 42 through the air supply port (not shown) by the power of the fan 49. Thus, while supplying the low temperature air SA to the living area 40 at the lower part of the smoking room 11, the inside of the smoking room 11 is stratified air-conditioning by exhausting contaminants such as dust and cigarette smoke together with the heated air from the upper part of the smoking room 11. In this embodiment, ventilation by replacement ventilation is performed, and the living area 40 below the smoking room 11 is also maintained in a clean low-temperature air SA environment. Further, in the living area 40 of the smoking room 11, the formation of an upward flow around it is promoted by the heat generated by the cigarettes in addition to the heat generated by the human body. Therefore, it is possible to prevent a situation in which cigarette smoke having a high dust concentration is transferred to a neighbor by a conventional blowing airflow, and a comfortable smoking environment is realized. Furthermore, stratified air conditioning is also performed in the living area 20 of the non-smoking room 10, so that tobacco smoke contained in the exhalation of the smoker can also be raised, and passive smoking derived from exhalation is prevented.

Here, as shown in FIG. 1, when the door 13 is closed, the motor damper 32 and the return air RA that adjust the amount of the outside air OA introduced into the air conditioner 25 of the non-smoking room 10 are controlled by the control unit 17. Both the motor damper 33 for adjusting the amount of air and the motor damper 53 for adjusting the amount of outside air OA introduced into the air conditioner 45 of the smoking room 11 and the motor damper 53 for adjusting the amount of return air RA are both opened. It is. Thereby, the return air RA and the outside air OA are supplied to the non-smoking room 10 as the low temperature air SA, and similarly, the return air RA and the outside air OA are supplied to the smoking room 11 as the low temperature air SA. Become. The living area 20 of the non-smoking room 10 and the living area 40 of the smoking room 11 are stratified air-conditioning, and the dust concentration is kept at 0.15 mg / m ³ or less. Furthermore, since the exhaust efficiency is high, the necessary ventilation amount is reduced, the amount of air-conditioned indoor air discharged to the outdoors can be reduced, and the running cost is reduced. Further, since the duct size can be reduced as compared with the mixed air conditioning, the installation is facilitated. Further, the layout restriction is eased by the differential pressure control between the opening 15 and the non-smoking room 10 and the smoking room 11.

  When the door 13 is closed, air is introduced from the non-smoking room 10 to the smoking room 11 through the opening 15 provided in the wall surface 12 (the upper end portion of the door 13). However, the position of the opening 15 is not the lower part of a pass opening such as an undercut of a conventional smoking room, but is located above the living areas 20 and 40, so that the stratified state of the living areas 20 and 40 is disturbed. There is nothing. Moreover, the outflow of the low-temperature air SA collected in the living area 20 of the non-smoking room 10 can be eliminated, and the thermal comfort of the living area 20 is maintained.

  On the other hand, as shown in FIG. 2, when the door 13 is opened, it is detected by the door switch 16 that the door 13 has been opened and is input to the control unit 17. Then, the control unit 17 fully opens the motor damper 32 that adjusts the amount of the outside air OA introduced into the air conditioner 25 of the non-smoking room 10, and the motor damper that adjusts the amount of the outside air OA introduced into the air conditioner 45 of the smoking room 11. 52 is closed and the motor damper 53 for adjusting the amount of the return air RA is fully opened. At this time, it is desirable that the motor damper 33 mounted on the return air duct 31 is fully opened. However, the opening degree may be about 15% from the viewpoint of heat reuse. The amount of air supplied from the air supply duct 26 is made larger than the amount of exhaust from the exhaust duct 55. That is, when the door 13 is opened, the outside air OA is taken into the smoking room 11 only at the opened door 13 portion, and the non-smoking room 10 to the smoking room 11 at the communicating part of the door 13. An air flow toward is formed. The wind speed becomes 0.2 m / s or more, for example, and leakage of tobacco smoke from the smoking room 11 to the non-smoking room 10 is prevented. In the present embodiment, the motor dampers 32, 33, 52, and 53 are controlled with emphasis on responsiveness. However, if the inverter or the like is improved, the non-smoking room 10 is always at a higher pressure than the smoking room 11. The control to be performed may be performed by the fans 28 and 56.

  According to the smoke separation air conditioning system 1, it is possible to prevent tobacco smoke from entering the non-smoking room 10 by forming a one-way flow from the non-smoking room 10 to the smoking room 11. In addition, the ventilation air volume can be reduced by improving the ventilation efficiency, the outside heat load is reduced, and the energy saving can be achieved by reducing the air conditioning power and the ventilation power. In addition, restrictions on the structure of the building such as a small OA / EA gallery area are alleviated. Further, in the smoking room 11, cigarette smoke can be raised above the living area 40 to keep cool air in the living area 40, improving comfort and preventing passive smoking inside and outside the smoking room 11. Can do. Furthermore, since it is possible to prevent tobacco smoke from entering the non-smoking room 10, for example, the non-smoking room 10 and the smoking room 11 can be arranged adjacent to each other, and the degree of freedom in building planning is increased. Note that an air conditioner 40 may be used as the air conditioner 40 in the smoking room 11. In that case, the return air RA may be taken in by stopping the blowing when the door 13 is opened or switching the dampers 52 and 53 in the same manner.

  Next, with reference to FIGS. 3-6, the smoke distribution air conditioning system 2 which concerns on embodiment of this invention applied to the floor blowing system is demonstrated. In the smoke separation air conditioning system 2, the non-smoking room 10 and the smoking room 11 are provided adjacent to each other. In addition, a wall 13 that partitions the non-smoking room 10 and the smoking room 11 is provided with a door 13 that allows the non-smoking room 10 and the smoking room 11 to communicate with each other. 3 to 5 each show a state where the door 13 is closed, and FIG. 6 shows a state where the door 13 is opened.

  Further, the wall surface 12 is provided with an opening 15 that allows the non-smoking room 10 and the smoking room 11 to communicate with each other at a position above the living areas 20 and 40. The opening 15 is formed in the upper end part of the door 13 also in the form of illustration. When the door 13 is closed as shown in FIGS. 2 to 5, the air in the smoking room 11 circulates between the non-smoking room 10 through the opening 15 at a position above the living areas 20 and 40. ing. The wall surface 12 is provided with a door switch 16 that detects opening and closing of the door 13.

  For example, a human 21 exists as a heating element in the living area 20 formed in the lower part of the non-smoking room 10. Similarly, for example, a human 41 is present as a heating element in the living area 40 formed below the inside of the smoking room 11. (Note that FIG. 3 shows that the smoking room 11 is not used, and therefore there is no human 41.)

  In this smoke separation air conditioning system 2, an air conditioning switch 60 for starting the air conditioning of the smoking room 11 and a cigarette smoke switch 61 for forcibly exhausting the cigarette smoke at the time of smoking are installed. ing.

  Further, in the smoke separation air conditioning system 2, a non-smoking room 10, a smoking room 11, and an air supply chamber 65 extended to the lower part of the floor surface are provided from one side of the non-smoking room 10. Air SA is supplied to the supply chamber 65 through the supply duct 67.

  An air supply port 70 is provided on the floor surface of the non-smoking room 10, and the low-temperature air SA supplied to the air supply chamber 65 is supplied into the non-smoking room 10 through the air supply port 70. An exhaust port 71 is provided in the ceiling surface of the non-smoking room 10, and the return air RA discharged from the non-smoking room 10 discharged from the exhaust port 71 is introduced into the air conditioner 66 through the return air duct 72. . A motor damper 73 for adjusting the air volume of the return air RA is attached to the return air duct 72. Outside air OA is also introduced into the air conditioner 66 through the outside air intake port 75. Between the outside air intake 75 and the air conditioner 66, a motor damper 76 for adjusting the air volume of the outside air OA is mounted.

  The air conditioner 66 cools the return air RA and the outside air OA to produce low-temperature air SA, and the low-temperature air SA is sent to the air supply chamber 65 via the air supply duct 67 by the operation of a fan (not shown). The air is blown upward into the non-smoking room 10 through the air supply port 70. In the non-smoking room 10, the low temperature air SA is blown upward from the air supply port 70 on the floor and exhausted from the exhaust port 71 provided on the ceiling surface. The area 20 is kept in a comfortable environment. In the non-smoking room 10, contaminants such as dust and gas generated around the human 21 are transported above the living area 20, and the air accumulated in the upper part of the non-smoking room 10 (heated air) is stirred. In other words, the air is returned to the air conditioner 66 through the exhaust port 71 and the return air duct 72 without disturbing the temperature stratification of the living area 20 formed in the lower part of the non-smoking room 10.

  An air supply port 80 is provided on the floor of the smoking room 11. The air supply port 80 includes, for example, a VAV, and is opened and closed in conjunction with the door switch 16 and the air conditioning switch 60. That is, as shown in FIG. 6, when the door 13 is opened, it is detected by the door switch 16 that the door 13 has been opened, and the air supply port 80 is closed. In addition, as shown in FIG. 3, when the air conditioning switch 60 is not turned on (when the air conditioning switch 60 is off), the air supply port 80 is closed. On the other hand, as shown in FIGS. 4 and 5, when the door switch 16 detects that the door 13 is closed and the air conditioning switch 60 is turned on, the air supply port 80 is opened. When the air supply port 80 is opened, the low-temperature air SA supplied to the air supply chamber 65 is supplied upward into the smoking room 11 through the air supply port 80. In order to realize stratified air conditioning, the air-conditioning air blowing device disclosed in Japanese Patent No. 375203 can be adopted as the air supply ports 70 and 80. The device can supply cold air along the floor during cooling. In addition, although a method of laying a carpet at the floor outlet as disclosed in Japanese Patent No. 3306641 can be adopted, for an operation mode in which the air inlet 80 is closed as described later, the air supply is blocked under the floor. Measures such as installing a damper are necessary.

  Two exhaust ports 81 and 82 are provided on the ceiling surface of the smoking room 11. A surplus exhaust duct 85 is connected to one exhaust port 81, and a surplus exhaust fan 86 is provided in the surplus exhaust duct 85. The surplus exhaust fan 86 is always in operation, and the air in the smoking room 11 is always exhausted EA from the exhaust port 81 provided on the ceiling surface. In addition, a cigarette smoke exhaust duct 87 is connected to the other exhaust port 82, and a cigarette smoke exhaust fan 88 is provided in the cigarette smoke exhaust duct 87. The operation of the tobacco smoke exhaust fan 88 is controlled by the tobacco smoke switch 61.

  Here, as shown in FIG. 3, when the door 13 is closed, the smoking room 11 is not used (for example, when there is no occupant), and only the non-smoking room 10 is air-conditioned (the smoking room 11). In the non-use mode), the air conditioning switch 60 is turned off, and the air supply port 80 of the smoking room 11 is closed. For this reason, the floor blowing to the smoking room 11 is not performed, and the low temperature air SA is supplied only to the non-smoking room 10. In the non-smoking room 10, the floor blowing type air conditioning is performed by blowing the low-temperature air SA upward from the floor air supply port 70 and exhausting it from the exhaust port 71 provided on the ceiling surface. (In this case, it is a normal floor blowing system.)

  In this case, for example, the discharge amount of the return air RA from the exhaust port 71 of the non-smoking room 10 is “40” with respect to the air supply amount (floor blowing amount) “100” into the non-smoking room 10, and the exhaust port of the smoking room 11. The exhaust amount of exhaust EA from 81 is set to “60”. Thereby, part of the air in the non-smoking room 10 is introduced from the non-smoking room 10 into the smoking room 11 through the opening 15 provided in the wall surface 12 (the upper end of the door 13), and the smoking room 11 is exhausted. The air is exhausted EA from the port 81 through the surplus exhaust duct 85.

  The smoking room 11 may be used as a smoking office. For example, as shown in FIG. 4, the door 13 is closed and the smoking room 11 is used. However, when there is no smoker and no smoking is performed (non-smoking mode of the smoking room 11), The air conditioning switch 60 is turned on, the air supply port 80 of the smoking room 11 is opened, and air conditioning of the smoking room 11 is started. Thus, similarly to the non-smoking room 10, in the smoking room 11, the low-temperature air SA is blown upward from the air supply port 80 on the floor surface and exhausted from the exhaust port 81 provided on the ceiling surface. Air conditioning is performed. As described above, when the smoking room 11 is used and there is no smoking (when the smoking room is clean), the cigarette smoke exhaust fan 88 need not be operated.

  In this case, for example, the air supply amount (floor blowing amount) into the smoking room 11 is similarly “100” with respect to the air supply amount (floor blowing amount) “100” into the non-smoking room 10, and the non-smoking room 10 is exhausted. The amount of return air RA discharged from the port 71 is “140”, the amount of exhaust EA discharged from the exhaust port 81 of the smoking room 11 is “60”, and the amount of outside air OA taken from the outside air intake port 75 to the air conditioner 66 is “60”. At this time, the exhaust amount from the exhaust port 82 is “0” due to the stop of the exhaust fan 88. Due to the negative pressure in the smoking room 11 rather than in the non-smoking room 10, a part of the air in the smoking room 11 passes from the smoking room 11 through the opening 15 provided in the wall surface 12 (the upper end of the door 13). 10 and returned to the air conditioner 66 from the exhaust port 71 of the non-smoking room 10 through the return air duct 67. That is, the temperature-controlled air is returned to the air conditioner 66 by “40” from the smoking room 11 that is not provided with the return air duct, and the cold energy is reused. In that case, the opening 15 also functions as a return air passage.

  In addition, as shown in FIG. 5, when the door 13 is closed and the person 41 is smoking in the smoking room 11 (smoking mode of the smoking room 11), the cigarette smoke switch 61 is turned on, As the cigarette smoke exhaust fan 88 is operated, the tobacco smoke is exhausted EA from the cigarette smoke exhaust duct 87. Even when the cigarette smoke is exhausted EA in this manner, in the non-smoking room 10, the low-temperature air SA is blown upward from the air supply port 70 on the floor surface and exhausted from the exhaust port 71 provided on the ceiling surface. Thus, floor-blowing air conditioning is performed, and the living area 20 is maintained in a comfortable environment. Similarly, in the smoking room 11, the low-temperature air SA is blown upward from the air supply port 80 on the floor surface, and is exhausted from the exhaust ports 81 and 82 provided on the ceiling surface. The living area 40 is maintained in a comfortable environment.

  In this case, for example, the air supply amount (floor blowing amount) into the smoking room 11 is similarly “100” with respect to the air supply amount (floor blowing amount) “100” into the non-smoking room 10, and the non-smoking room 10 is exhausted. The discharge amount of the return air RA from the port 71 is “80”, the discharge amount of the exhaust EA from the exhaust port 81 of the smoking room 11 is “60”, and the discharge amount of the exhaust EA from the exhaust port 82 of the smoking room 11 is “ 60 ”. Thereby, only “20” of air in the non-smoking room 10 is introduced from the non-smoking room 10 into the smoking room 11 through the opening 15 provided in the wall surface 12 (the upper end portion of the door 13). Further, only “20” of the outside air OA is taken into the air conditioner 66 from the outside air inlet 75. Further, the exhaust air is exhausted EA from the exhaust ports 81 and 82 of the smoking room 11 through the surplus exhaust duct 85 and the tobacco smoke exhaust duct 87. In the opening 15, air flows from the non-smoking room 10 to the smoking room 11 so as to meet the air balance between the non-smoking room 10 and the smoking room 11. Even when a smoker enters the non-smoking room 10, the exhaled air containing cigarette smoke rises by buoyancy without spreading into the living area 20 because it is warm. The air quality of the non-smoking room 10 is not deteriorated. In addition, when smoking, the cigarette smoke exhaust fan 88 is operated and the outside air introduced into the air conditioner 66 by adjusting the opening degree of the motor dampers 73 and 76 (the motor damper 73 is fully closed and the motor damper 76 is fully opened). It is desirable to increase the amount of OA. In addition, the non-smoking mode and the smoking mode of the smoking room 11 can be switched by a human 41 inside the smoking room 11 by pressing a switch or by a cigarette smoke sensor or an infrared sensor for detecting combustion heat. Good.

  In addition, as shown in FIG. 6, when the door 13 is opened (door 13 opening mode), it is detected by the door switch 16 that the door 13 is opened, and the air supply port 80 of the smoking room 11 is opened. Closed. For this reason, the floor blowing to the smoking room 11 is not performed, and the low temperature air SA is supplied only to the non-smoking room 10. Thereby, in the non-smoking room 10, the low temperature air SA is blown upward from the air supply port 70 on the floor surface, and exhausted from the exhaust port 71 provided on the ceiling surface, thereby performing floor blowing type air conditioning. The area 20 is kept in a comfortable environment. When the door 13 is opened, the outside air OA is taken into the smoking room 11 only at the opened door 13 portion.

  In this case, for example, the discharge amount of the return air RA from the exhaust port 71 of the non-smoking room 10 is “80” with respect to the air supply amount (floor blowing amount) “200” into the non-smoking room 10, and the exhaust port of the smoking room 11. The exhaust amount of exhaust EA from 81 is “60”, and the exhaust amount of exhaust EA from the exhaust port 82 of the smoking room 11 is “60”. Thereby, the air flowing into the smoking room 11 from the non-smoking room 10 through the door 13 becomes “40”. By setting the relationship between the flow rate of the air “40” and the part of the opened door 13 in advance, the wind speed of air flowing from the non-smoking room 10 to the smoking room 11 through the door 13 part is set to 0.2 m / By setting it as s or more, the leakage of the tobacco smoke from the smoking room 11 to the non-smoking room 10 is prevented effectively.

  The present invention can be similarly applied to floor blowing type air conditioning like the smoke separation air conditioning system 2. In the case of the floor blowing method, the air conditioner 66 is provided with an inverter, and is operated so that the differential pressure between the floor (air supply chamber 65) and each room is constant. The amount of air exhausted EA from the inside of the smoking room 11 through the surplus exhaust duct 85 and the tobacco smoke exhaust duct 87 (the amount of exhaust from the smoking room 11 excluding those subjected to return air) is Non-use mode ≦ non-smoking mode of smoking room 11 <smoking mode of smoking room 11 ≦ open mode of door 13 In the embodiment described with reference to FIGS. 3 to 6, the amount of exhaust from the smoking room 11 except for the one attached to the return air is the same in the non-smoking mode of the smoking room 11 and the non-smoking mode of the smoking room 11, and smoking Although the example in which the smoking mode of the chamber 11 is equal to the opening mode of the door 13 is shown, the non-smoking mode of the smoking room 11 <the non-smoking mode of the smoking room 11 may be set, or the smoking mode of the smoking room 11 < The door 13 may be in an open mode. In this case, the above exhaust amount relationship can be realized by performing inverter control on the operation of the surplus exhaust fan 86 provided in the surplus exhaust duct 85 and the cigarette smoke exhaust fan 88 provided in the cigarette smoke exhaust duct 87. it can. When the door 13 is opened, since the area of the door 13 itself is large, the wind speed of the air flowing from the non-smoking room 10 into the smoking room 11 through the opened door 13 is not necessarily increased.

  As mentioned above, although embodiment of this invention was illustrated and demonstrated, this invention is not limited to this example. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs to.

  For example, the opening 15 that allows the non-smoking room 10 and the smoking room 11 to communicate may be provided on the wall surface 12 instead of the door 13. Coolers for producing low-temperature air may be provided in the return air ducts 31, 51, 72, the outside air duct 30, the branch outside air duct 50, the outside air intake port 75, etc., respectively. It is reasonable to install the cooler at the position after joining the air conditioners 25, 45, 66 and the air supply units 22, 42, etc.

  The smoking room 11 is generally assigned a smaller space than the non-smoking room 10. In addition, the smoking room 11 temporarily accommodates a large number of people (at the end of the meeting, lunch break, etc.). Therefore, a variable air volume device may be laid in the system of the smoking room 11. In the case of the floor blowing method, this variable air volume device can employ the blowout device of Japanese Patent No. 4528009. However, if the air conditioners 25 and 45 are separately provided in the smoking room 11 and the non-smoking room 10 as shown in FIG. Similarly, in the method of FIG. 1, if the air conditioners 25 and 45 are shared, it is better to install a variable air volume device in the smoking room 11 for the same reason. Whether the air conditioner is divided between the smoking room 11 and the non-smoking room 10 or shared is also somewhat different in the system design even in a full-surface floor blowing system such as Japanese Patent No. 3306641. In other words, if it is provided separately, an underfloor damper is not required (the underfloor boundary of the room is closed), and it is only necessary to supply and exhaust air through the same duct route as in FIG.

  The present invention can be applied to the case where a non-smoking room and a smoking room are separated and air-conditioned.
