Airconditioner

Abstract

Abstract PURPOSE:To make it possible to select freely cooling or heating operation in each room by designing an airconditioner which allows a capacity variation of a capacity variable type compressor and effects switch over of an outdoor side change over valve, conforming to the temperature of each indoor heat exchanger or the pressure of refrigerant or the temperature of air blowoff for a indoor unit where cooling or heating operation is being carried out. CONSTITUTION:For example, when an indoor side change over valve for indoor units 5a and 5c to be cooled are set to cooling state, while an indoor side change over valve for an indoor unit 5b to be heated are set to heating state at the same time, a part of refrigerant discharged from a capacity variable type compressor flows only to a paired outdoor heat exchanger 3a while the rest of the refrigerant flows to an indoor heat exchanger 6b for the indoor unit 5b to be heated by way of a high pressure pipe 12, and get condensed and liquefied by this heat indoor heat exchanger and an outdoor heat exchanger 3b. The refrigerant is distributed to a pressure reducing device for each indoor unit 5a, and 5c to be cooled by way of a liquid pipe 14. Then, it is vaporized in each indoor heat exchanger 6a, and 6c, and absorbed into the compressor 2 by way of a low pressure gas pipe 13.
