In the industry, chillers are divided into two types: air-cooled chillers and water-cooled chillers. In terms of temperature control, chillers are divided into low-temperature chillers and normal-temperature chillers. The normal temperature is generally controlled within the range of 0-35 degrees. Low temperature machine temperature control is generally in the range of 0 degrees-minus 45 degrees.
The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate when the refrigerant chiller reinstates the system, and a certain temperature difference is formed between the refrigerant and the water. The gaseous refrigerant releases heat through the condenser and condenses into a liquid. After throttling through the thermal expansion valve, it turns into a low-temperature and low-pressure refrigerant and enters the evaporator, completing the refrigerant cycle.
