Control device for an air conditioner

摘要

An object of the present invention is to provide an air conditioner in which the feedback of liquid refrigerant to a compressor is prevented and whose refrigerating cycle is constituted with an indoor side heat exchanger, a compressor, an outdoor side heat exchanger, and a pressure reducer. The controller of the air conditioner comprises a temperature control means which performs the cooling operation for a room in controlling the start or 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.
