More Information
Summary:Air conditioner in which the feedback of liquid refrigerant to a compressor is prevented and whose refrigerating circuit includes an indoor heat exchanger (17), a compressor (9), an outdoor heat exchanger (11), and a pressure reducer (16). The controller of the air conditioner comprises a temperature control means which performs the cooling operation for a room by controlling the start and stop of the operation of the compressor based on the change of the room temperature, a protective means which stops the operation of the compressor compulsorily independent of the operation of the temperature control means when the open air temperature becomes lower than a specified temperature, and a display means for displaying the operation of the protective means.
