(Embodiment 1)
As shown in FIG. 1, a heat exchanger 1 for cooling and heating and a circulation fan 2 are provided to cool and heat indoor air, and a heat exchange element 3, an air supply fan 4 and an exhaust fan 5 are provided. In the device 6 having a ventilation function for exchanging heat by exchanging heat in the room air, the circulation fan 2, the supply air fan 4, and the exhaust fan 5 are arranged coaxially with one motor 7. The circulation fan 2 is a circulating fan. Further, the air supply fan 4, the exhaust fan 5, and the air passage 8 of the circulation fan 2 are provided independently. Further, the motor cover 10 is inserted into the suction port of the air supply fan 4 or the exhaust fan 5. In addition, a discharge port 12 to the outside air provided in the outer frame 11 and an outside air intake port 13 for taking in the outside air are provided at both ends in the lateral direction of the main body 14. The motor 7 is DC driven. It is configured as described above.

  In the above configuration, the single fan 7 drives the circulation fan 2 to suck indoor air, cools and heats it with the heat exchanger 1 and returns it to the room, and drives the air supply fan 4 from the outside air inlet 13. After sucking outside air and exchanging heat with the air exhausted from the room through the heat exchange element 3, the air is supplied to the room, the exhaust fan 5 is driven, and the room air is sucked from the indoor air intake port 9. Heat is exchanged with the outside air sucked into the room through the exhaust port 12 and exhausted to the outside. Since the fans having the above three configurations can be driven at one time, motors for supplying and exhausting air and for circulating are not required as compared with independent fans, and the apparatus 6 can be reduced in size, and the motor is applied. Power consumption can also be reduced. In addition, since the cooling / heating fan does not require static pressure, the circulation fan 2 can be used as a recirculation fan. Therefore, compared with the conventional sirocco fan, the air is supplied to the room through the heat exchanger 1 evenly. In addition, it becomes possible to achieve small size and low power consumption. In addition, since the air passage 8 for indoor air to the outside and the air passage 8 for outdoor air to the room are performed by separate fans, there is no lack of ventilation capacity or lack of air conditioning. Moreover, since the air from the room or the air from the outside comes into contact with the motor 7, the temperature rise of the motor 7 can be prevented and the performance can be stably exhibited. Further, since the air flowing from the outdoor to the indoor and from the indoor to the outdoor flows in parallel to the heat exchange element 3, the contact time becomes longer, and as a result, the heat exchange efficiency can be improved. In addition, since the motor is DC driven, power consumption can be kept low.

  The ventilator with an air conditioning function according to the present invention is small in size and low in power consumption, can supply air stably indoors, can be downsized, and can be stably supplied indoors. It is possible to prevent the temperature of the motor from rising and the performance can not be lowered, the heat exchange efficiency between the outside air and the indoor air can be improved, and the motor can have low power consumption. It is useful as a ventilator with an air-conditioning function that can be installed on an indoor wall surface of a house or the like.
