ABSTRACT:
A refrigerating cycle machine characterized by comprising hardware or software means for raising the speed of rotation of the compressor or stopping the fan for producing an air current through the condenser when the operation of the machine is turned off and stopping the operation of the machine when a predetermined time has elapsed. This increases the suction and discharge pressure difference to such an extent that generates a sufficiently high pressure difference between both sides of the valve body to move the valve body toward the closing position surpassing the sticking force when the machine stops.
