  On the other hand, for example, when considering the air supply of an air conditioner for the purpose of air conditioning of a kitchen, it is considered that a normal heating device is installed in the kitchen and the room temperature is locally high in the vicinity of the heating device. There is a need to. When air conditioning is performed on an indoor space with a high-temperature heat source in this way, there is a need for a local air conditioning function using a spot duct at the same time as air conditioning of the entire room. Therefore, a spot duct-equipped air conditioner in which a spot duct is also provided at the direct outlet of the ceiling-suspended air conditioner has been proposed for such needs. As an air conditioner equipped with a spot duct, a configuration is known in which spot ducts are arranged at two end portions of a long straight outlet.

  When a spot duct is also provided at the direct outlet, it is more effective to operate the spot duct with a high air flow and a high static pressure compared to the direct air outlet. Therefore, it is necessary to adjust the air volume inside the unit.

  Here, as the air volume adjusting means, for example, as in Patent Document 2, a plurality of fans are arranged in the front and back of the unit, and the motors of some of the fans are rotated to reduce the air volume of only the fans. The technology to do is known.

The blower 30 includes a fan 31 that is rotated by an electric motor (not shown) about an axis extending in the opposing direction of the pair of side surfaces 14 and 14 of the housing 10. The fan 31 blows air from the rear surface 13 side in the housing 10 and the air below the blower 30 toward the front surface 12 in the housing 10. The blower 30 has a casing 32 that covers the fan 31. On the back side and the bottom side of the casing 32, a blowing port 33 through which the air blown by the fan 31 is discharged is formed on the front side of the casing 32.

  The control box 40 is disposed at a position where the air flow between the heat exchanger 20 and the blower 30 is not blocked. In the present embodiment, such a position is provided so as to be fixed to the rear surface 13 of the housing 10 inside the housing 10. The control box 40 stores a control unit that controls various devices incorporated in the ceiling-suspended air conditioner 1.

  The partition plate 50 divides the space inside the housing 10 into two spaces, a heat exchanger side region R1 in which the heat exchanger 20 is disposed and a blower side region R2 in which the blower 30 is disposed.

  The partition plate 50 includes a first partition surface 51 extending in a plate shape from the upper surface 11 of the housing 10 toward the lower surface 15 and a second partition surface extending from the lower portion of the first partition surface 51 toward the front surface 12 side of the housing 10. A partition surface 52. The lower end of the first partition surface 51 is not in contact with the lower surface 15 of the housing 10 and is connected to the second partition surface 52. Therefore, as shown in FIG. 2, the partition plate 50 has a substantially L-shape when viewed from the side surfaces 14 and 14. The second partition surface 52 opposes the suction port 15a provided in the lower surface 15 of the housing 10 in the vertical direction. In the present embodiment, the front end of the second partition surface 52 is formed to be bent downward, and the lower end of the bent portion is in contact with the lower surface 15 of the housing 10.

  Here, as shown in FIGS. 2 and 4, the first partition surface 51 of the partition plate 50 is formed with a blowing hole 51 a and a reflux hole 51 b.

  The air hole 51a is an opening for introducing the air from the blower 30 into the heat exchanger side region R1, and penetrates the first partition surface 51 in the front-rear direction. The ventilation hole 51 a has a rectangular shape extending in the width direction of the housing 10, that is, in the opposing direction of the pair of side surfaces 14, 14, and is formed at a position close to the upper side of the first partition surface 51.

In the present embodiment, the front end of the air blowing port 33 in the casing 32 of the blower 30 is in contact with the first partition surface 51 from the back side, and at this time, the air blowing hole 51 a is accommodated inside the air blowing port 33. Thereby, all of the air blown from the blower port 33 is introduced into the heat exchanger side region R1 through the blow hole 51a.

The reflux hole 51b is formed below the blow hole 51a in the first partition surface 51, and has a rectangular shape extending in the width direction of the housing 10 like the blow hole 51a. ing. The reflux hole 51b communicates the heat exchanger side region R1 and the space below the blower 30 in the blower side region R2. Thereby, the air recirculated to the blower side region R2 through the recirculation hole 51b is sucked into the blower 30 again.
The reflux hole 51b is not limited to a rectangular shape, and may be any shape such as a circle, an ellipse, or a square.
Further, if the blower 30 sucks air from above, the reflux hole 51b may be formed above the blow hole 51a.

The reflux hole closing portion 60 is a plate-like member along the first partition surface 51. The reflux hole closing portion 60 is disposed in the heat exchanger side region R <b> 1 of the partition plate 50.
The reflux hole closing portion 60 closes at least a part of the reflux hole portion 51b. That is, the reflux hole closing portion 60 is configured so that the closing area of the reflux hole portion 51b can be arbitrarily changed. The recirculation hole closing portion 60 that closes at least a part of the recirculation hole portion 51b so as to have a predetermined closed area may be, for example, screwed and fixed by other fixing means such as an adhesive. It may be. In addition, it may be provided so as to be slidable with respect to the first partition surface 51 so that the closed area can be easily changed once the closed area is determined.

As shown in FIGS. 1 and 3, the spot opening blocking portion 70 is a plate material that can block the spot opening portions 12b and 12b. In this embodiment, the spot opening opening portion 12b on the left side as viewed from the front is formed. It is fixed to block.
The spot duct 80 is a bellows tube-shaped member formed of a flexible material. In this embodiment, one end of the spot duct 80 is connected to the spot-side opening 12b on the road side as viewed from the front. It is provided as follows. Since the spot duct 80 can be moved indoors, cold air or warm air can be locally sent in the vicinity of the heat source in the room. In addition to direct blowing from the vicinity of the ceiling of the ceiling-suspended air conditioner 1, cooling and heating local air conditioning is possible.

Next, the construction method (manufacturing method) of the air conditioning equipment in which the ceiling-suspended air conditioning apparatus 1 according to the present embodiment is installed at a place where the room is installed will be described with reference to the flowchart shown in FIG.
In the air conditioning equipment construction method of the present embodiment, as shown in FIG. 5, first, the ceiling-suspended air conditioning apparatus 1 having the above configuration is prepared (step S1).

  Next, the ceiling-suspended air conditioner 1 is adjusted (step S2). This adjustment operation includes a step of determining the closed area of the reflux hole 51b (step S21) and a step of closing the reflux hole 51b (step S22).

  In step S21, the closed area of the reflux hole 51b is determined according to the environment in which the ceiling-suspended air conditioner 1 is installed. Here, the installation environment refers to the temperature and humidity of the installation room, the thermal load, the air conditioning function required according to this, and whether local air conditioning is required in the installation room. This relates to the loss, etc. of the spot duct 80 such as the length, diameter and material of the spot duct 80 and the number of spot ducts 80. The amount of blowing air required for the air conditioner 1 is estimated according to the environment in which these are installed.

  For example, as the environment A to be installed, when the heat load is large and local air conditioning is required, and the position where local air conditioning is necessary is far from the installation position of the air conditioner, the length of the spot duct 80 becomes long. Moreover, when the location where local air-conditioning is needed is wide, the spot duct 80 diameter becomes large.

  For example, as the environment B to be installed, when the heat load is small and local air conditioning is required, and the position where local air conditioning is required is close to the installation position of the air conditioner, the length of the spot duct 80 becomes short. Moreover, when the location which requires local air conditioning is a narrow range, the spot duct 80 diameter becomes small.

  Here, in the case of the installed environment A, compared with the case of the installed environment B, the amount of blowing air required for the air conditioner 1 is estimated to be large. In this case, in the case of the installed environment A, the closed area of the reflux hole 51b is determined to be larger than in the case of the installed environment B.

  Subsequently, in step S22, based on the determination of the closed area in step S22, at least a part of the reflux hole 51b is closed by the reflux hole closing part 60 so as to become the closed area. Thereby, the adjustment work of the ceiling-suspended air conditioner 1 is completed.

  Thereafter, the ceiling-suspended air conditioner 1 is installed at the installation location (step S3). Thereby, the procedure of the construction method of the air conditioning equipment using the ceiling-suspended air conditioning apparatus 1 is completed.

  In the air conditioner 1 having the above-described configuration, the fan-side region R2 in the vicinity of the opening surface of the suction port 15a formed in the lower surface 15 of the housing 10 becomes negative pressure due to the rotational drive of the electric motor of the blower 30, and the air pressure is reduced from the suction port 15a to the room. Air is sucked into the blower side region R <b> 2 in the housing 10.

  In the ceiling-suspended air conditioner 1, the upper surface 11 of the casing 10 is arranged along the ceiling and the rear surface 13 is arranged along the wall surface. Therefore, the lower surface 15 widely faces the indoor space of the air-conditioned room. It becomes easy to suck in by providing the suction port 15a. In addition, when the return hole 51b is provided in the second partition surface 52 that faces the suction port 15a without sandwiching the blower 30, the return direction in the return hole 51b is In the opposite direction, air easily moves from the blower side region R2 to the heat exchanger side region R1 due to the sucked air, and it is difficult to secure a reflux amount, resulting in poor reflux efficiency.

  The room air introduced into the blower side region R2 through a filter (not shown) that removes dust and the like from the suction port 15a passes through the blower port 33 and the blow hole 51a by the rotation of the fan 31, and then the blower side region. The air is blown from R2 to the heat exchanger side region R1.

  The air blown to the heat exchanger side region R1 is converted into conditioned air having the amount of heat necessary for indoor air conditioning via the heat exchanger 20 in the heat exchanger side region R1, and from the outlet 12a. Supplied indoors.

  When only a part of the reflux hole 51b is closed, a part of the air blown to the heat exchanger side region R1 is returned to the blower side region R2 through the reflux hole 51b. . Thereafter, the recirculated air is sucked again by the blower 30 and introduced into the heat exchanger side region R1 through the blower port 33 and the blower hole 51a.

  By performing such recirculation, the amount of air blown from the air outlet 12a is reduced as compared with the case where no recirculation occurs. As a result, even if the fan 31 has a simple configuration that rotates at a constant speed without controlling the number of revolutions of the fan 31, it is possible to ensure the necessary amount of blowing air from the outlet 12 a.

Moreover, according to the construction method of the air conditioning equipment described above, it is possible to secure a necessary blowing air volume estimated according to the environment of the installation location.
As in the case of the installed environment A, compared with the case of the installed environment B, when the amount of blown air necessary for the installation room environment is large, heat exchange is performed by increasing the closed area of the reflux hole 51b. The amount of recirculation from the fan side region R1 to the blower region R2 can be reduced. As a result, the amount of recirculation is reduced, and the amount and pressure of air blown from the heat exchanger side region R1 can be increased. Therefore, it is possible to easily adjust the air volume with a simple configuration.
That is, by setting the closed area of the reflux hole 51b according to the environment of the installation location, it can be easily set which of the indoor air conditioning and the local air conditioning is dominant.

  Next, the construction method of the air conditioning equipment of the second embodiment of the present invention will be described with reference to the flowchart shown in FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

This embodiment is different from the first embodiment in that the closed area of the reflux hole 51b is set according to the closed area of the spot openings 12b and 12b.
As shown in FIG. 6, in the present embodiment as well, as in the first embodiment, first, the air conditioner 1 having the above-described configuration is prepared (step S1).

  Next, the air conditioner 1 is adjusted (step S12). This adjustment work includes a step of determining the closed area of the spot openings 12b and 12b (step S121), a step of closing the spot openings 12b and 12b (step S122), and a closed area of the reflux hole 51b. And a step of closing the reflux hole 51b (step S124).

In step 121, the closed areas of the spot openings 12b and 12b are determined according to the environment where the ceiling-suspended air conditioner 1 is installed.
Here, the installation environment refers to the temperature and humidity of the installation room, the thermal load, the air conditioning function required according to this, and whether local air conditioning is required in the installation room. This relates to the loss in the flow path of the spot duct 80 such as the length, diameter and material of the spot duct 80, the number of spot ducts 80, and the like. The amount of blowing air required for the air conditioner 1 is estimated according to the environment in which these are installed.

  For example, the installed environment C has a large heat load and requires local air conditioning. The number of spot ducts 80 is one, and the position where local air conditioning is required is far from the installation position of the air conditioner. In this case, the length of the spot duct 80 is increased, and the diameter of the spot duct 80 is increased when a portion where local air conditioning is required is wide.

  Further, when the installed environment D has a small heat load and local air conditioning is not required, the necessary blowout air volume / wind pressure is smaller than the installed environment C.

  In the case of the environment C to be installed, when there are a plurality of spot openings 12b and 12b as in the ceiling-suspended air conditioner 1 of the present embodiment, the required number of spot openings 12b and 12b is one. The blocking area for closing the other spot opening 12b is determined.

  In the case of the environment D to be installed, a closed area for closing all the spot openings 12b and 12b is determined in FIG.

  In step S122, the spot openings 12b and 12b are closed by the spot opening closing part 70 so as to have the closing area determined in step S121.

  In the case of the installation environment C, as shown in FIG. 3, one spot opening 12b, 12b is used for one spot among the two spot openings 12b, 12b at both ends of the outlet 12a. The opening is blocked by the opening blocking portion 70.

  In the case of the environment D to be installed, as shown in FIG. 7, two spot opening blocking portions 70 are used to block the two spot opening portions 12b and 12b at both ends of the outlet 12a.

  In step S123, the closed area of the reflux hole 51b is determined according to the closed area of the spot openings 12b and 12b.

  In the case of the installed environment D, the spot duct 80 is not necessary, and the closed area of the spot openings 12b and 12b is larger than that in the case of the installed environment C. In this case, the installed environment D is determined to be smaller than the installed environment C in terms of the blown air volume and pressure required for the ceiling-suspended air conditioner 1, and the closed area of the reflux hole 51b102 is determined to be small. The

  The closed area of the reflux hole 51b is determined based on the correlation that the closed area of the reflux hole 51b is reduced as the closed areas of the spot openings 12b and 12b are increased. That is, the size relationship between the closed areas of the spot openings 12b and 12b and the size relationship between the closed areas of the reflux holes 51b have a negative correlation, and the spot openings 12b determined in step S121. , 12b, the closed area of the reflux hole 51b is determined.

  In step S124, the reflux hole 51b is closed by the reflux hole closing part 60 so as to be the closed area of the reflux hole 51b determined in step S123.

  In the case of the installed environment D, as compared with the case of the installed environment C, the return hole blocking portion 60 is reduced so that the closed area of the return hole 51b is reduced according to the closed area determined in step C. Thus, the reflux hole 51b is closed.

  Thereafter, the ceiling-suspended air conditioner 1 is installed at the installation location (step S3). Thereby, the procedure of the construction method of the air conditioning equipment using the ceiling-suspended air conditioning apparatus 1 is completed.

In the air-conditioning equipment constructed as described above, the installed environment C has a smaller closed area of the spot openings 12b and 12b and a larger closed area of the reflux hole 51b than the installed environment D. . In this case, local air conditioning is more dominant than indoor air conditioning. On the other hand, in the environment D to be installed, indoor air conditioning is dominant.
Therefore, also in this embodiment, as in the first embodiment, either the indoor air conditioning or the local air conditioning is controlled by setting the closed area of the reflux hole 51b based on the closed area of the spot openings 12b and 12b. Can be easily set.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like within a scope not departing from the gist of the present invention. .

  In addition, in the said embodiment, although the air conditioning apparatus 1 was installed in the use room and what was made into the usable state is expressed as an air conditioning equipment, other processes, such as a connection process with an outdoor unit, are represented. It may be passed.

Moreover, you may provide not only one fan 30 but multiple. In this case, a plurality of blowing holes 51 a are formed corresponding to the number of blowers 30. In this case, a plurality of reflux holes 51b may be provided. Of these, only a part of the reflux holes 51b may be closed.

  In addition, in the first and second embodiments, the ceiling-suspended air conditioner 1 is adjusted after the ceiling-suspended air conditioner 1 is prepared, and then the ceiling-suspended air conditioner 1 is installed. After installing the suspended air conditioner 1, the ceiling suspended air conditioner 1 may be adjusted.
