Air conditioning apparatus and method of controlling the air conditioning apparatus

Abstract

An air conditioning apparatus includes a refrigerant circuit, a refrigerant heating unit and a stop signal controller. The refrigerant circuit includes a compressor, an indoor heat exchanger, a pressure reducing mechanism, and an outdoor heat exchanger. The refrigerant heating unit heats refrigerant flowing through the refrigerant circuit. The stop signal controller, in a case of causing the compressor to stop at a time when the compressor and the refrigerant heating unit are both operating, executes first stop control in which a stop signal is issued in order to stop the refrigerant heating unit, and then a stop signal is issued in order to stop the compressor after elapse of a first amount of time. A method of controlling an air conditioning apparatus having the refrigerant circuit and the refrigerant heating unit includes executing the first stop control.
