摘要： An air-conditioning apparatus provided with a ceiling-mounted indoor unit that uses a refrigerant having a greater specific gravity when gasified than air, wherein the reliability of refrigerant leakage detection is improved. An indoor machine (40A, 40B) is at least one indoor unit in which an intake port and a blow-out port are formed, the indoor unit having an indoor fan (43) for drawing indoor air in from the intake port and blowing conditioned air out from the blow-out port, an intake temperature sensor (46), an indoor-side refrigerant circuit (11 a, 11 b) for circulating a refrigerant having a greater specific gravity when gasified than air and producing conditioned air from the indoor air, and a refrigerant temperature sensor (47a, 47b, 47c) for detecting the temperature of the refrigerant in the indoor-side refrigerant circuit (11 a, 11 b). A control device (30) drives the indoor fan (43) in accordance with an operation mode and/or a detection value of the refrigerant temperature sensor (47a, 47b, 47c), and detects refrigerant leakage through the use of the refrigerant gas sensor (45).

摘要： Provided is a refrigeration apparatus that detects refrigerant leakage or refrigerant charge deficiency while restraining costs increasing. An air conditioning system (100) is equipped with a subcooling heat exchanger (16), a second outdoor expansion valve (15), a first refrigerant flow rate computing component (55), a second refrigerant flow rate computing component (56), and a refrigerant quantity determining component (57). The subcooling heat exchanger (16) includes a first flow path (161) disposed on a refrigerant primary circuit (RC1) and a second flow path (162) disposed on a bypass circuit (RC2). The second outdoor expansion valve (15) is disposed on an upstream side of the subcooling heat exchanger (16) in the bypass circuit (RC2). The first refrigerant flow rate computing component (55) calculates, as a first refrigerant flow rate (Fr1) on the basis of refrigeration cycle theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The second refrigerant flow rate computing component (56) calculates, as a second refrigerant flow rate (Fr2) on the basis of fluid theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The refrigerant quantity determining component (57) determines refrigerant leakage or refrigerant charge deficiency on the basis of a result of a comparison of the first refrigerant flow rate (Fr1) and the second refrigerant flow rate (Fr2).
