The first port (101) is connected to target equipment (10) from which a refrigerant is collected. The second port (102) is connected to a container (110) in which the refrigerant collected from the target equipment (10) is put. The refrigerant channel (30) connects the first port (101) and the second port (102). The refrigerant channel (30) includes at least an expansion mechanism (40), a compressor (80), and a heat exchanger (90). The identifying unit (210) identifies the type of the refrigerant that is being collected from the target equipment (10). On the basis of a first value and a second value, the identifying unit (210) identifies the type of the refrigerant that is being collected from the target equipment (10). The first value relates to a first refrigerant temperature, which is a refrigerant temperature on the first-port-(101) side of the compressor (80). The second value relates to a second refrigerant temperature, which is a refrigerant temperature on the second-port-(102) side of the compressor (80).

摘要： A leakage diagnosis apparatus for diagnosing presence/absence of refrigerant leakage in a refrigerant circuit performing a refrigeration cycle, wherein refrigerant leakage diagnosis using the amount of refrigerant exergy loss in a circuit component of the refrigerant circuit is realized. In a leakage diagnosis apparatus (50), an exergy calculation section (52) calculates a leakage index value which changes in accordance with the amount of refrigerant leaking out of a refrigerant circuit (20) based on the amount of refrigerant exergy loss in the circuit component. Then, a leakage determination section (53) determines whether there is refrigerant leakage in the refrigerant circuit (20) based on the leakage index value calculated by the exergy calculation section (52).

摘要： An air conditioning apparatus and a refrigerant quantity determination method are provided, whereby a refrigerant quantity can be determined in a simple and accurate manner without compromising the reliability of a compressor. A refrigerant circuit (10) has a compressor (21), an outdoor heat exchanger (23) that functions as a condenser, an indoor expansion valve (41, 51), an indoor heat exchanger (42, 52) that functions as an evaporator, an indoor unit interconnection pipe (4b, 5b), a liquid refrigerant connection pipe (6), a gas refrigerant connection pipe (7), and an outdoor unit interconnection pipe (8). A controller (9) performs liquefaction control for liquefying refrigerant and placing the refrigerant in a portion extending from the indoor expansion valve (41, 51) to the outdoor heat exchanger (23). The controller (9) directly or indirectly regulates the flow rate of refrigerant flowing through a liquid bypass circuit (70) from a liquid reserving portion (Q) toward the gas refrigerant connection pipe (7). A liquid level detection sensor (39) detects at least one of either a volume of liquid refrigerant in the portion where liquid refrigerant accumulates and a physical quantity equivalent to the volume.
