Refrigerator unit control system

The utility model relates to the technical field of refrigeration, and discloses a refrigerator unit control system, which has the following effects in the operation process of a unit by using a low-starting torque compressor and an electromagnetic valve in a refrigeration system and using a low-voltage switch and a time relay on a control circuit: 1, the low-starting torque compressor is adopted; the purpose of greatly reducing the manufacturing cost of the unit is achieved; 2, a low-voltage switch is adopted to control the start and stop of the unit, so that the temperature control of a plurality of refrigerators can be realized when one unit is provided with two or more refrigerators; and 3, an electromagnetic valve is mounted between a liquid outlet of the condenser and an air return port of the compressor, a time relay is used in a control circuit, time delay is performed before the compressor is started, and the electromagnetic valve is opened to realize high-pressure and low-pressure balance, so that t
