<p>An air-conditioning apparatus includes a compressor 1, a four-way valve 3, expansion means 5, and an indoor heat exchanger 7, and further includes a check valve 2 disposed between a discharge side of the compressor 1 and the four-way valve 3, a first solenoid valve 6 disposed between the expansion means 5 and the indoor heat exchanger 7, and a controller 9. Opening and closing of the first solenoid valve 6 are controllable. The controller 9 switches the four-way valve 3 and switches the first solenoid valve 6 between open and closed states. When a heating operation is stopped, the controller 9 switches the four-way valve 3 from connection for the heating operation to connection for a cooling operation, closes the first solenoid valve 6, and then stops the compressor 1.</p> |
