Abstract

PURPOSE: To perform cooling and heating operation at the same time in a plurality of indoor machines connected to one outdoor machine, by connecting each indoor heat exchanger with each two-way valve in the middle of the refrigerant pipe connecting an outdoor heat exchanger to a four-way valve, and interposing an opening and closing valve in each branch pipe. CONSTITUTION: In the case of performing cooling operation as to first and second indoor heat exchangers 17a and 17b, and heating operation as to a third indoor heat exchanger 17c, each two-way valve 19a and 19b linked each to the first and second indoor heat exchangers 17a and 17b is opened and opening and closing valves 23a and 23b are closed by the switching operation of a four-way valve 12. Two-way valve 19c linked to the third indoor heat exchanger 17c is closed, and the opening and closing valve 23c is opened. The gas-form refrigerant at high temperature and high pressure having flowed out of the four-way valve 12 are shunted into an outdoor heat exchanger 13 and a connection pipe 20. The gas-form refrigerant at high temperature and high pressure shunted to the connection pipe 20 is liquefied, being heated with a third indoor heat exchanger 17c, and that on the side of other throttle devices 18a and 18b after being decompressed by the second throttle device 18c.
