An air conditioning apparatus includes a casing, a heat exchanger and a blower. In the casing, an intake port is formed and a blow-off port is formed in a top surface section. The heat exchanger and the blower are housed in the casing. The blower is caused to rotate while a flammable refrigerant flows to the heat exchanger during an operation, an intake air is taken into the casing from the intake port, a heat exchange is carried out between the flammable refrigerant and the intake air in the heat exchanger, and the heat-exchanged air is blown out from the blow-off port to an exterior of the casing. A first refrigerant sensor that detects the flammable refrigerant is disposed on a downwind side of the heat exchanger inside the casing.

A heat-recovery-type refrigerating apparatus includes a compressor, a heat-source-side heat exchanger, and a plurality of usage-side heat exchangers, and refrigerant is sent from the usage-side heat exchanger functioning as a refrigerant radiator to the usage-side heat exchanger functioning as a refrigerant evaporator, whereby heat can be recovered between the usage-side heat exchangers. Here, a portion of the heat-source-side heat exchanger is configured as a precooling heat exchanger for always circulating high-pressure vapor refrigerant discharged from the compressor, and a refrigerant cooler for cooling an electrical equipment item is connected to a downstream side of the precooling heat exchanger.
