Abstract

PURPOSE: To allow simultaneously cooling and warming operation by forming a piece of piping between units connecting an outdoor unit and a plurality of indoor units of three refrigerant pipes composed of a high pressure gas pipe, low pressure gas pipe and a liquid pipe.
CONSTITUTION: In the time of simultaneously cooling and warming operation in whole rooms, change valves 9a, 15aW15c are opened, change valves 9b, 14aW14c are closed and the refrigerant of a compressor 2 is flowed through a discharge pipe 7, and outdoor heat exchanger 3, a liquid pipe 13, a refrigerant decompressors 16aW16c of each indoor unit 5aW5c, indoor heat exchangers 6aW6c, a low pressure gas pipe 12 and a refrigerant suction pipe 8. In the time of warming operation in the whole rooms, which change valve is set in a warming condition, the refrigerant from the compressor 2 is fed into heat exchangers 6aW6c in each room through a high pressure gas pipe 11 and returned from a liquid pipe 13. In the time of simultaneously cooling and warming operation, the change valve of the outdoor heat exchanger 3 is set in the warming condition, the other change valves of the indoor heat exchangers 6aW6c are changed in accordance with cooling and warming, a part of the refrigerant from the compressor 2 is fed into the outdoor heat exchanger 3 and the residual is flowed in the indoor heat exchangers 6aW6c for warming through the high pressure gas pipe 11.
