To improve space-saving and construction performance, to reduce noise generated by a device, and further to reduce exhaust noise to a bathroom, the other living space and the outside of a house.
All of a compressor 27, a first heat exchanger 28, an expanding mechanism 29 and a second heat exchanger 30 constituting a refrigerant circuit are received in this ventilation air-conditioning device to improve space-saving and construction performance, and further the ventilation air-conditioning device comprises sensor microphones 45, 48 and 49 detecting sounds generated from drive sources in a main body 6, converting the sounds into electric signals and outputting them, speakers 46, 50-55 generating sounds on the basis of the input electric signals, and an active noise controller 41 generating electric signals of opposite phases to the electric signals outputted from the sensor microphones 45, 48 and 49, and outputting the signals to the speakers 46, 50-55, thus the noise of the device can be reduced.
