In an air conditioner having an electrical equipment mount device containing at least one circuit board on which electrical parts connected to wires are mounted, plural wire abutting portions are formed on a wire fixing face so as to be different in height from said wire fixing face, and a wire is fixedly pinched between a wire press member and one of the wire abutting portions that is selected in accordance with the diameter of the wire. The wire fixing face has a conduit fixing member having a conduit fixing face to which one end portion of a conduit having electrical wires inserted therein is fixed. Plural engaging holes are formed in the wire fixing face, and the conduit fixing member is equipped with plural engaging members which are fixedly engageable with the engaging holes of the electrical equipment mount plate. The engaging members are located at different positions on the conduit fixing member with respect to the conduit fixing face.

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.

Control device for an air conditioner

An air-conditioner comprises a refrigerating circuit having a compressor, a condenser, an expansion device and an evaporator which are connected by suitable refrigerant conduits. An electric current path for making a current flow through the compressor includes an AC power source, to which a current transformer is coupled, and an output of the current transformer is converted into a DC voltage which is then given as a (+) input of a comparator. A reference voltage is given to a (-) input of the comparator. When the DC voltage exceeds the reference voltage of the comparator, the high level is outputted from the comparator. When the high-level output from the comparator persists for three seconds, the compressor is stopped forcedly and a three-minute timer is turned on. After a lapse of three minutes, the flow of the current through the current path of the compressor is resumed. Thereby, a lightly locked state is removed. If the output of the comparator still remains at the high level when the energizing is resumed, the compressor is put in the stopped state again. When such stopping and resuming of energizing of the compressor are repeated four times, the energizing of the compressor is stopped assuming that the compressor is in a heavily locked state.
