  The structure of low-temperature chillers is similar to that of piston chillers. Low-temperature chillers generally refer to chillers whose outlet temperature is less than or equal to 5°C. They are mainly used for process cooling in food processing, chemical, pharmaceutical and other industries. Low-temperature chillers are usually used for low-temperature requirements on certain special production lines in the industry. Low-temperature chillers can generally reach about -40°C. Low-temperature chillers  are quite different from conventional chillers in terms of unit design due to the lower temperature of the outlet water. The most basic difference is that on the chilled water side, the cryogenic unit needs to be added with the appropriate type and concentration of antifreeze. Low-temperature chillers include low-temperature air-cooled chillers, low-temperature water-cooled chillers, low-temperature screw chillers, and low-temperature piston chillers. So how to control the temperature

  Recently, when communicating with some customers, we found that we were not very clear about the type selection and system design of low temperature units. However, the   low temperature chiller   is a very important equipment for chemical industry, raw material pharmaceutical factory and other enterprises, and it is also the place with the largest energy consumption for such enterprises. Therefore, how to select the appropriate number of industrial low temperature chiller and design a reasonable frozen water circulation system is particularly important. There is an example on  H.Stars Group  project reference.To us, the key points of  glycol chiller  design ,take the recent project of Anhui Xiangbang Chemical Co., Ltd. as an example, the total cooling capacity demand of the enterprise is 1500kW, and the outlet water temperature is required to be - 15 ℃. According to the experience, the following three points are sorted out for your reference: 1、 Selection of the number of refrigerat
