How the Single Spiral Freezer works in everyday life
Refrigerator refers to a mechanical equipment that uses a compressor to change the pressure of the refrigerant gas to achieve low-temperature refrigeration. The compressor used is different from the general air compressor due to its different operating conditions and compressed working medium.

Do you know about its working principle and the relevant knowledge of the refrigerant cycle system? Follow the editor of Single Spiral Freezer to have a simple understanding!
1. Working principle
The unit uses the heat exchange principle to reduce the chilled water temperature to the required temperature through a heat exchanger (normal ≥5℃, low temperature ≥-20℃), and the water is pumped into the evaporation tank through the chilled water pump for heat exchange, producing chilled water, which is sucked in by the pump Drive into the evaporator water tank for circulation. When the chilled water is insufficient, the chilled water flow cannot push the water flow switch blades, and the refrigerator stops running. At this time, the automatic water replenishment device starts to work to replenish water. The water level of the water tank can be judged by the liquid level display, and the chiller is turned on again.
2. Refrigerant circulation system
The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. A certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also evaporates completely and becomes a gas, which is sucked by the compressor and compressed (pressure and temperature increase) , The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After being throttled by the expansion valve, the low-temperature and low-pressure refrigerant enters the evaporator to complete the refrigerant cycle process.
The above is the introduction of Single Spiral Freezer editor: about the working principle of the freezer and other related knowledge.
