Abstract

PURPOSE: To protect the compressor from overloading and as well as prevent the waste of electric power by a method wherein the controlling operation is performed to change the compressor to low capacity operation and to stop the power supply to an electric heater when the detected electric current consumption exceeds a predetermined value.
CONSTITUTION: In a 20A limiting circuit 21, a current detecting part 33 connected with a current comparing part 38 is provided. When the current consumption exceeds the predetermined value, low voltages are generated from comparators 51 and 52 which are supplied to a bistable multivibrator 70 to interrupt transistors 68 and 72 and conduct in a transistor 74. As a result, a control relay 29 is energized and a control relay 30 is deenergized and the compressor is turned in low capacity operation and as well as the power supply to the electric heater is cut off. Accordingly, the compressor can be protected from overloading without the stoppage of operation and the waste of electric power can also be avoided.
