chiller is divided into two types: air-cooled chiller and water-cooled chiller. The chiller is divided into a low-temperature chiller and a normal-temperature chiller for temperature control. 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.
When a chiller refrigerant is cycled, the liquid refrigerant in the evaporator absorbs heat in the water and begins to evaporate. A certain temperature difference is formed between the final refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state and is inhaled by the compressor. After compression, the gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After the throttling of the thermal expansion valve, the refrigerant turns into a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle.
