ABSTRACT:
In concurrent operation of performing a refrigeration cycle in which an outdoor heat exchanger (22) functions as a condenser, and at least one of a plurality of indoor heat exchangers (31, 41, 51) functions as a condenser, pressure difference ΔP1between a high pressure refrigerant an a refrigerant in a liquid pipe (15) is detected, and the degree of opening of an outdoor expansion valve (23) is adjusted so that the pressure difference ΔP1becomes larger than a predetermined target value.
