One of the design principles of Ice Cream Freezer Suppliers is to ensure the quality of ice cream freezers, that is, compressors. At present, fixed displacement compressors and variable displacement compressors are commonly used in the market.

1. The fixed displacement compressor cannot automatically change the power transmission according to the demand of refrigeration, and has great influence on the oil consumption of the engine. Its control is generally realized by collecting the temperature signal from the evaporator air outlet. When the temperature reaches the set temperature, the compressor stops working. When the temperature rises, the compressor starts to work. The constant displacement compressor is also controlled by the pressure of the air conditioning system. When the pressure in the pipeline is too high, the compressor stops working.

2. During the whole refrigeration process of the ice cream freezer with variable displacement compressor, the compressor is always working, and the adjustment of the refrigeration intensity is completely controlled by the pressure regulating valve installed inside the compressor. When the pressure in the high pressure end of the ice cream freezer pipeline is too high, the pressure regulating valve shortens the piston stroke in the compressor to reduce the compression ratio, thus reducing the refrigeration intensity. When the high-pressure end pressure drops to a certain degree and the low-pressure end pressure rises to a certain degree, the ice cream freezer throttle valve increases the piston stroke to improve the refrigeration intensity.

What needs to be reiterated here is that the compressor quality of ice cream freezers is very important. Although there are many types of compressors for ice cream freezers, the compressors for ice cream freezers are different according to different working principles. A good compressor can prolong the service life of ice cream freezers and achieve better refrigeration effect.
