Abstract
There is provided an air conditioner with a refrigerant sensor installed in a room, which can reduce the amount of refrigerant leakage while limiting the installation cost of a shut-off valve. The air conditioner includes a liquid-side shut-off valve connected between an outdoor heat exchanger and an indoor unit-side expansion valve, a gas-side shut-off valve connected between an indoor heat exchanger and a compressor, a bypass passage in which one end is connected between the liquid-side shut-off valve and the indoor unit-side expansion valve and the other end is connected between the gas-side shut-off valve and the compressor, and a bypass solenoid valve configured to open and close the bypass passage.
