Factors affecting the evaporation temperature of industrial chillers

In industries such as pharmaceuticals, food, and chemicals, process water cooling is required for temperature reduction, and industrial chillers have become a must-have equipment in many industries. However, industrial chillers are damaged during use, so we need to regularly record and analyze their operating parameters, and perform regular maintenance operations for them. So what are the factors that affect the evaporation temperature of industrial chillers? 

1. Blockage of the drying filter: In order to ensure the normal circulation of the refrigeration system, the refrigeration system must be kept clean and dry. If there are impurities in the system, it will cause blockage of the drying filter, making it difficult to supply liquid to the system and affecting the refrigeration effect.

2. Evaporator pipeline oil accumulation: Under normal circumstances, due to the mutual solubility of lubricating oil and Freon, no oil film will form on the surface of the heat exchanger. Therefore, the thermal resistance of the oil film can be ignored. However, when adding lubricating oil, it is necessary to use the same grade of lubricating oil as the original to prevent the formation of oil film. The selection of evaporator varies depending on different models, for example, box type chillers use water tank coil evaporators; For open type chillers and screw type chillers, shell and tube evaporators are selected; For acid and alkali resistant chillers, titanium tube evaporators or stainless steel plate exchangers can be selected. An industrial chiller with multiple options, and of course, it can be customized according to user needs.

3. Evaporator temperature condition: Under normal circumstances, the outer surface of the evaporator is very cold, and condensed water droplets continuously drip down. The inlet and outlet air temperatures are relatively high. Under abnormal circumstances, the evaporator surface is not too cold, with little dew or no condensation, and a loud sound of refrigerant flow can be heard. The temperature difference between the inlet and outlet air is small.

That's all for the factors that affect the evaporation temperature of industrial chillers. While providing industrial cold water to customers, industrial chillers can also supply a large amount of free sanitary hot water. The heating system increases cooling during operation, resulting in high energy utilization and heat recovery of up to 30-80% of the cooling capacity.
