FIG. 1 is a sketch of a living space in which a ventilation air conditioner according to an embodiment of the present invention is installed. In FIG. 1, an indoor living space 1 is divided into a living room 2 as an indoor space, a bathroom 3, a dressing room 4, a toilet 5, a corridor 6, and the like. 7 is installed. The main body 7 ventilates the first duct 8 that communicates with the main body 7 outdoors, the second duct 10 that communicates with the first suction port 9 opened in the ceiling of the dressing room 4 and the main body 7, and the living space 1. A third duct 12 that connects the exhaust port 11 opened in the ceiling of the corridor 6 and the main body 7 is connected. Here, the exhaust port 11 may be attached to the living room 2 or the toilet 5 or the like.

  In addition, a ventilation fan 13 is disposed inside the main body 7, and a first duct 8 that communicates the outdoor body with the main body 7 is connected to the blowing side of the ventilation fan 13, and a second passage that communicates the dressing room 4 and the main body 7. A duct 10 and a third duct 12 communicating the corridor 6 and the main body 7 are connected to the suction side of the ventilation fan 13. Therefore, when the ventilation fan 13 is operated, the air in the dressing room 4 and the corridor 6 is sucked into the ventilation fan 13 from the first suction port 9 and the exhaust port 11 through the second duct 10 and the third duct 12, and through the first duct 8. Exhausted outdoors.

  And if the ventilation fan 13 is continuously operated, the inside of the indoor living space 1 becomes negative pressure, so fresh outside air is supplied from the air supply opening 14 opened on the wall facing the outside of the living room 2 as the indoor space. The living space 1 will be ventilated. Since this ventilation operation needs to be performed continuously when the confidentiality of the building is high (24-hour ventilation), the ventilation fan 13 corresponds to a predetermined ventilation amount, for example, about half the volume of the living space 1 in one hour. Operate continuously to ensure ventilation.

  The living room 2 is provided with an air conditioner 15 for controlling the temperature of the room, and the room temperature is appropriately maintained by performing cooling operation in summer and heating operation in winter. Therefore, when continuous ventilation operation is performed throughout the year as described above, in the living room, the air conditioner 15 is used for cooling in the summer, and the air conditioner 15 is used for heating in the winter.

Thus, heating and dehumidification of both of the bathroom 3 and the dressing room 4 can be performed by performing the circulation ventilation using the bathroom 3 and the dressing room 4 as one room in a pseudo manner.

  Next, FIG. 3 shows a schematic diagram when air circulation in the bathroom is simultaneously performed in the air circulation route in heating and dehumidification of both the bathroom 3 and the dressing room 4 of the ventilation air conditioner. In the bathroom 3, air is sucked from both the first suction port 9 installed in the dressing room 4 and the second suction port 31 installed in the bathroom 3 by the circulation fan 21 and blown into the bathroom 3. Therefore, the bathroom 3 and the dressing room 4 are circulated as a single room in a circulated manner, and at the same time, the circulated air in the bathroom is increased, so that the amount of air blown out from the outlet installed in the bathroom and the wind speed are increased. Since the air conditioned by the whole becomes easy to reach, it is possible to heat and dehumidify both the bathroom 3 and the dressing room 4 and further improve the efficiency of the air conditioning in the bathroom.

In the bathroom 3, a third suction port 55 is provided as an opening different from the second suction port 31, and a fourth damper 56 is provided as a closing mechanism for the third suction port 55.

  During the dehumidifying operation, the ventilation fan 13 and the circulation fan 21 are operated to suck the air in the dressing room 4 from the first ventilation port 45. Since the sucked air passes through the evaporator 47 cooled to the dew point temperature or less by operating the compressor 50, the temperature and the absolute humidity are lowered. A part of the air whose temperature and absolute humidity are reduced is exhausted from the living room space 1 by the ventilation fan 13 through the ventilation outlet 48. In addition, another part of the air whose temperature and absolute humidity are reduced by the evaporator 47 passes through the third damper 54 and passes through the heated condenser 43, so that the temperature rises and the relative humidity decreases. . The air whose relative humidity is reduced passes through the outlet 22 by the circulation fan 21 and is blown into the bathroom 3.

  Further, by opening the fourth damper 56 provided in the third suction port 55, air is sucked from the bathroom 3 and passes through the evaporator 47 and the condenser 43 in this order, so that the relative humidity is reduced. By blowing out air having a reduced relative humidity, it is possible to simultaneously perform circulating ventilation in the bathroom 3.

(Embodiment 3)
FIG. 5 shows an air path configuration diagram of a ventilation air conditioner when an electric heater or a hot water coil is used as heating means for heating. By operating the circulation fan 21, air is sucked from the first ventilation port 45 and the second ventilation port 46, and the air sucked by the heating means 71 is heated. As this heating means, an electric heater or a hot water coil can be considered. The heated air is structured to blow out from the outlet 22 opened in the bathroom 3.

  Furthermore, by providing the second suction port 31 in the bathroom 3, air can be sucked from both the bathroom 3 and the dressing room 4 and blown out from the outlet 22.

  Moreover, when heating the inside of the bathroom 3 and the dressing room 4, in order to prevent a decrease in heating efficiency due to the air heated by the heating means 71 being discharged outside the living space 1, By providing and closing the ventilation damper 72 on the upstream side, it is possible to separate the outside of the living space 1 from the heating air passage.

As described above, the ventilation air-conditioning apparatus according to the present invention can perform air-conditioning in a sub-ventilation air-conditioning target space other than the main ventilation air-conditioning target space with a minimum configuration, not only in a bathroom ventilation air-conditioning but also in a living room and bedroom It can also be applied to a ventilation air conditioner or the like in a kitchen or a washroom.
