The accessories of glycol chiller mainly include compressor, evaporator, condenser and throttling device. These are the main accessories of the chiller, which can directly affect the performance and use of the chiller. The compressor is the core of the chiller, and the performance of the compressor can directly affect the performance of the whole chiller. Industrial water chillers are widely used in all walks of life, such as chemical, pharmaceutical, electroplating, plastic, laser and other industries. Each part of the chiller is also very important. It is also recommended that you learn more about the performance of these parts when you use it.
Generally speaking, the accessories of glycol chiller mainly include compressor, evaporator, condenser and throttling device. These are the main accessories of the chiller, which can directly affect the performance and use of the chiller. The compressor is the core of the water chiller. The performance of the compressor can directly affect the performance of the whole water chiller, and the performance index of the compressor directly determines and limits the performance of the water chiller. Generally, manufacturers will choose international brands of compressors. The evaporator and condenser inside the ethylene glycol refrigerator directly affect the performance of the compressor, such as changes in evaporation temperature, condensation temperature, superheat, and subcooling. Therefore, brand selection is also important.
The commonly used water chillers generally use shell and tube type water chiller evaporator and condenser. The following factors can affect the performance of the water chiller evaporator and condenser:
The reasonable structure of the homogenizer of the low-temperature water chiller can maximize the uniform distribution of the refrigerant at the evaporator inlet between the heat exchange tubes, and alleviate the gas-liquid separation phenomenon.
However, the inner end cover 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 reasonable 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 great impact on its performance. The distribution proportion of the number of heat exchange tubes between different processes can be optimized to obtain a better proportion of heat exchange effect. Corrugated inner finned tubes with high performance can also be selected, which can not only enhance the heat transfer at the fluorine side, but also strengthen the heat transfer at the water side.
However, it should be noted that the water leakage between the baffle plate and the shell of the glycol cooler will seriously affect the heat transfer at the water side of the cooler. Therefore, in addition to taking measures on the baffle structure, the water velocity at the shell side can also be optimized to obtain a reasonable water velocity.
According to the relationship between evaporation and heat transfer in the tube of the chiller, the evaporation in the tube is obviously affected by the mass flow rate of the refrigerant in the tube, and the mass flow rate of the refrigerant decreases gradually along the length of the evaporation heat transfer tube.
