Abstract (en)
A circuit for blocking an operation of a compressor includes a compressor power supply unit (320) including a relay (321) to supply power to the compressor when the relay is turned on, a micro-computer (360) to control an on/off state of the relay, a relay power supply unit (330) to apply power to the relay, and a switching unit (340) to cut off the power applied to the relay, based on pressure of a refrigerant.
