Abstract (en)
An air-conditioning apparatus includes an outdoor unit and an indoor unit, the outdoor unit having at least a compressor, a refrigerant flow path switching device, a heat source side heat exchanger, and a first expansion device, the indoor unit having at least a load side heat exchanger and a second expansion device, the compressor, the refrigerant flow path switching device, the heat source side heat exchanger, the first expansion device, the load side heat exchanger and the second expansion device being connected by refrigerant pipes to form a refrigerant circuit a first valve device provided at a refrigerant pipe of the refrigerant pipes, the refrigerant pipe connecting between the first expansion device and the second expansion device; a second valve device provided at a refrigerant pipe of the refrigerant pipes, the refrigerant pipe connecting between the refrigerant flow path switching device and the load side heat exchanger; and a controller configured to control the first expansion device during a cooling operation mode to expand, into a two-phase gas-liquid state, refrigerant flowing through the first expansion device to the refrigerant pipe between the first expansion device and the second expansion device. The first valve device and the second valve device are closed when leakage of the refrigerant is detected.
