Abstract

PURPOSE: To prevent the generation of refrigerant noise due to a difference in a refrigerant pressure by a method wherein, during simultaneous cooling heating operation, a second on-off valve is closed and a third on-off valve is opened, and during switching from heating to cooling operation, a high pressure refrigerant in an indoor heat exchanger flows through a bypass pipe to a liquid pipe, and after a refrigerant pressure is reduced, the second on-off valve is opened.
CONSTITUTION: When two rooms are cooled and one room is heated, the one switching valve 9a of an outdoor heat exchanger 3 is opened and simultaneously the other switching valve 9b is closed. Further, first on-off valves 16a and 16c of indoor units 5a and 5c where cooling is effected are closed and simultaneously second on-off valves 17a and 17c and third on-off valves 23a and 23c are opened, and a first on-off valve 16b of an indoor unit 5b where heating is effected is opened and simultaneously a second on-off valve 17b and a third on-off valve 23b are closed. When, during heating operation of all rooms, for example, only the indoor unit 5b is switched to cooling operation, a high pressure refrigerant flows to a liquid pipe 13 through a bypass pipe 21b by means of which the first on-off valve 16b and a refrigerant pressure reducer 18b are closed, and after a refrigerant pressure in an indoor heat exchanger 6b is reduced, the second on-off valve 17b is closed.
