DISCHARGE PRESSURE ABNORMAL RISE PREVENTION APPARATUS FOR REMOTE CONDENSER TYPE FREEZER

摘要

PROBLEM TO BE SOLVED: To provide a discharge pressure abnormal rise prevention apparatus wherein an abnormal rise of discharge pressure is prevented at the start of a remote condenser freezer. ;SOLUTION: A bypass circuit 5 is provided, which includes an opening/closing mechanism such as a solenoid opening/closing valve 51 is interposed between a discharge piping 12 and a high pressure liquid refrigerant line in a body unit 1 of a remote condenser type freezer, and the bypass circuit 5 is opened for a short time after starting of the freezer by opening/closing the opening/ closing mechanism. The life of the opening/closing mechanism is prolonged by opening the bypass circuit 5 is opened only when the freezer is started in the state where surrounding air temperature of a condenser unit 2 exceeds a predetermined value or in the case where interruption time of the freezer exceeds a predetermined value.;COPYRIGHT: (C)1998,JPO
