Performance of Accessories of Glycol Chiller
Industrial chillers are widely used in various industries, such as chemical, pharmaceutical, electroplating, plastics, laser and other industries can be used, each of its accessories is also very important, everyone also recommends when using it Learn more about the performance description of these accessories.
Generally speaking, the accessories of the glycol chiller mainly include compressor, evaporator, condenser and throttling device. These are the main accessories of the chiller, which can directly affect the performance of the chiller. The compressor is the core of the chiller. The performance of the compressor can directly affect the performance of the entire chiller, and the performance index of the compressor directly determines and limits the performance of the chiller. Generally, manufacturers will choose international brands of compression machine. The evaporator and condenser inside the ethylene glycol refrigerator will directly affect the performance of the compressor, such as the changes in evaporating temperature, condensing temperature, superheat and subcooling, so the choice of brand is also very important.
Commonly used water machines generally use shell-and-tube chiller evaporators and condensers, which can affect the performance of the chiller evaporators and condensers. Generally, there are the following factors:
The reasonable structure of the homogenizer of the low-temperature chiller can maximize the uniform distribution of the refrigerant at the inlet of the evaporator between the heat exchange tubes, and alleviate the phenomenon of gas-liquid separation. However, the inner end cap profile converted in different processes should be as smooth as possible to reduce resistance, avoid gas-liquid separation, and make R404 refrigerant evenly distributed among the heat exchange tubes in the next process.
The rational distribution of the number of heat exchange tubes in different processes of the chiller, the structure and length of the heat exchange tubes have a greater impact on its performance. The distribution ratio of the number of heat exchange tubes between different processes can be optimized, so as to obtain a ratio with a better heat exchange effect. You can also choose high-performance corrugated inner finned tubes, which not only enhances the heat transfer on the fluorine side, but also on the water side.
However, it should be noted that the occurrence of water leakage between the baffle and the shell of the glycol chiller will seriously affect the heat transfer on the water side of the chiller. Therefore, in addition to taking measures on the baffle structure, the water velocity on the shell side can also be optimized to obtain a more reasonable water velocity.
water chiller can be found from the relationship between the evaporation and heat exchange in the tube, the evaporation in the tube is obviously affected by the mass flow rate of the refrigerant in the tube, and the length direction of the salt evaporation heat exchange tube changes, the mass flow rate of the refrigerant is gradually reduced.
