5. Refrigeration system

5. 1. Energy saving advantages of refrigeration electronic expansion valve (Simplified diagram)	(1) According to different low-temperature testing conditions, the control system uses PID algorithm to control the flow opening of the electronic expansion valve and quickly and accurately control the refrigerant cooling output amount, ensuring that the compressor operates in the optimal output state. (2) Compared to traditional refrigeration technology, Sailham's self-developed intelligent control system is more energy-efficient. When the user sets a low temperature value in advance, it unloads the excess cooling capacity and does not cause low temperature overshoot by starting the heating tube to offset the excess cooling capacity, thereby achieving energy-saving and energy-saving effects. (3) The energy consumption ratio of the refrigeration system is well controlled, while extending the service life of the compressor.
