The invention relates to a refrigerating unit for a ship, and belongs to the field of ship equipment. The refrigerating unit of a ship refrigeratory is characterized by comprising a ship scroll compressor, wherein exhaust air from an air cooler of the refrigeratory is communicated to the ship scroll compressor through an air and liquid inlet pipe; a hot spraying device is arranged on the air and liquid inlet pipe, and is connected with the ship scroll compressor; a sucking port of the ship scroll compressor is provided with a pressure control device; a discharge port of the ship scroll compressor is provided with a temperature control device; gas or liquid discharged from the discharge port of the ship scroll compressor passes through an oil separator and a condenser, and is fed to the air cooler of the refrigeratory after being filtered; the pressure control device induces the air sucking pressure of the compressor, and outputs signals to the hot spraying device; the temperature control device induces the exhaust temperature of the compressor, and outputs signals to the hot spraying device; and the hot spraying device adjusts the input/output air quantity of the ship scroll compressor according to the pressure signals, and adjusts the refrigerating capacity of the ship scroll compressor according to the temperature signals.
