ルチコンプレッサユニットの運転制御回路。For each compressor in a multi-compressor unit consisting of multiple compressors connected in parallel to a refrigeration circuit, the order in which the power is turned on is determined so that each compressor is started in sequence with a short time interval when parallel operation starts, and Among these, the control circuit of the magnetic contactor for opening and closing the compressor for the compressor whose power is turned on later in the order includes a hydraulic protection switch and various protection switch contacts including this switch. In the operation control circuit of a multi-compressor unit that is connected to a delay relay that is slightly delayed from that of the opening/closing magnetic contactor, a hydraulic protection switch is connected in parallel to the series circuit of the delay relay and magnetic contactor. An operation control circuit for a multi-compressor unit for a refrigerator, characterized by:
