摘要： A refrigerant circuit of a refrigeration cycle apparatus has a compressor, a cooling-heating switching mechanism, a condenser, a refrigerant expansion mechanism, and an evaporator. During operation of the compressor, the refrigerant expansion mechanism opens the refrigerant circuit, a first three-way valve connects an outlet of the compressor to the condenser, and a second three-way valve connects an inlet of the compressor to the evaporator. During stop of the compressor, the refrigerant expansion mechanism closes the refrigerant circuit, the first three-way valve connects the outlet of the compressor to the evaporator, and the second three-way valve connects the inlet of the compressor to the evaporator.

摘要： An air-conditioning apparatus includes two heat source units, each including a compressor, an outdoor heat exchanger functioning as an evaporator, an accumulator connected to a suction side of the compressor, and at least one of an outdoor air-sending device configured to supply air corresponding to a heat exchange target for refrigerant to the outdoor heat exchanger or a flow control device (bypass and expansion device for bypass) configured to regulate a flow rate of the refrigerant flowing through the outdoor heat exchanger. A controller is configured to control at least one of the outdoor air-sending device or the flow control device so that a suction quality of the compressor of an upper heat source unit installed on an upper side and a suction quality of the compressor of a lower heat source unit installed on a lower side become the same.

摘要： An air conditioning system includes a bypass passage and a cooling-heating switching mechanism. The bypass passage is configured to be at least a part of a flow passage connecting a third port to a refrigerant inlet of a compressor. A second expansion valve opens and closes the bypass passage. The cooling-heating switching mechanism includes check valves and four-way valves. The four-way valve causes a refrigerant outlet of the check valve to communicate with one of the refrigerant inlet and a refrigerant outlet of the compressor. The four-way valve causes a refrigerant inlet of the check valve to communicate with one of the refrigerant inlet and the refrigerant outlet of the compressor and causes a port to communicate with the other of the refrigerant inlet and the refrigerant outlet.

摘要： A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a first heat exchanger, an expansion mechanism, and a second heat exchanger are connected by pipes. The first heat exchanger includes a first refrigerant passage and a second refrigerant passage that share a plurality of fins with each other and provided in parallel in the refrigerant circuit. The apparatus further includes a high-and-low-pressure switching mechanism which is located on an inlet side of the second refrigerant passage of the first heat exchanger in flowing of refrigerant in an operation in which the first heat exchanger functions as a condenser, and which performs switching between flow directions of the refrigerant. The apparatus further includes a refrigerant blocking mechanism located on an outlet side of the second refrigerant passage of the first heat exchanger in the flowing of the refrigerant in the operation, and which blocks the flowing of the refrigerant.

摘要： A notifier notifies a user of a warning when a ratio of first refrigerant is different from a suitable value, the ratio being determined from a first difference between a first temperature and a second temperature and from a second difference between a third temperature and a fourth temperature. The first temperature is a temperature of non-azeotropic refrigerant mixture between first heat exchanger and a second heat exchanger. The second temperature is a temperature of the non-azeotropic refrigerant mixture between the second heat exchanger and first expansion valve. The third temperature is a temperature of the non-azeotropic refrigerant mixture between a first decompressor and first connecting point. The fourth temperature is a temperature of the non-azeotropic refrigerant mixture between a second decompressor and the first connecting point.
