In chemical manufacturing, it is often necessary to maintain the temperature between 20–32°C; with a temperature difference of 5°C, the evaporation temperature should be between 15–27°C. However, no models that meet these requirements are available at present, so generally the evaporation temperature is set at 12.5°C. Generally, the greater the difference between the condensing temperature and the evaporating temperature of a refrigeration unit, the lower its energy efficiency ratio. To save electricity, it is advisable to choose the highest possible evaporating temperature and the lowest possible condensing temperature. In some processes, it is necessary to pursue low energy consumption, such as in the wastewater treatment process. Under such operating conditions, the temperature of the cooling tower is unstable, and using a chiller results in relatively high energy consumption. I would like to know if there are any refrigeration compressors available for such operating conditions The compression ratio of such a refrigeration compressor should be relatively low, right? Thank you!
