    摘要: A compressor (2), a heat releasing element (3A) of a heat exchanger (3) for heating, an electromotive expansion valve (4), and a heat absorbing element (5A) of a heat exchanger (5) for cooling are connected to each other to constitute a primary refrigerant circuit. A pump (11), a heat absorbing element (3B) of the heat exchanger (3) for heating, a first indoor heat exchanger (12), an electromotive expansion valve (13), a second indoor heat exchanger (14), and a heat releasing element (5B) of the heat exchanger (5) for cooling are connected to each other to compose a secondary refrigerant circuit (10). A liquid refrigerant ejected from the pump (11) is evaporated in the heat absorbing element (3B) of the heat exchanger (3) for heating, reduced in pressure by the electromotive expansion valve (13), and evaporated in the second indoor heat exchanger (14). Thereafter, the gas refrigerant is condensed in the heat releasing element (5B) of the heat exchanger (5) for heating to be returned to the pump (11).

    摘要: Two outdoor units (2A, 2B) are connected in parallel to a main liquid line (7L) and a main gas line (7G). Three indoor units (3A, 3B, 3C) are connected in parallel to the main liquid line (7L) and the main gas line (7G). The outdoor units (2A, 2B) are each provided with an oil equalization mechanism (9A, 9B) for conducting a surplus out of lubricating oil stored in an oil reserving part (91) provided on the discharge side of a compressor (21) to the suction side of a compressor (21) of another outdoor unit (2A, 2B). In cooling operation, the respective oil equalization mechanisms (9A, 9B) control respective gas bypass passages (95, 96) and respective oil equalizing bypass pipes (93, 94) to open and close them so that lubricating oil flows alternately between the outdoor units (2A, 2B), thereby equalizing lubricating oil. In heating operation, the respective oil equalization mechanisms (9A, 9B) control the respective oil equalizing bypass pipes (93, 94) to open and close them so that lubricating oil flows alternately between the outdoor units (2A, 2B) and hold the downstream sides of the oil equalization mechanisms (9A, 9B) in low pressure condition, thereby equalizing lubricating oil.

    摘要: A heat exchanger (1) on the secondary heat source, which exchanges heat with a heat exchanger (12) on the primary heat source in a primary cooling circuit (A), is connected with an indoor heat exchanger (3) through a gas pipe (6) and a liquid pipe (7), which are provided with solenoid valves (SV1, SV2), respectively. Only the solenoid valve (SV2) of the liquid pipe (7) is opened at the time of heat radiation of the heat exchanger (12) on the primary side and the liquid cooling medium is supplied from the heat exchanger (1) on the secondary side to the indoor heat exchanger (3) by the high vapor pressure of the cooling medium evaporated from the heat exchanger (1). Only the solenoid valve (SV1) of the gas pipe (6) is opened at the time of heat absorption of the heat exchanger (12) and the gas cooling medium is recovered from the indoor heat exchanger (3) to the heat exchanger (1) by the low vapor pressure of the cooling medium condensed by the heat exchanger (1).
