Patent attributes
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.
