Chiller is a kind of cooling equipment, which can provide constant temperature, constant flow and constant pressure cooling water equipment.Because of the need of production, many enterprises will use industrial chillers, but because of the wide variety of chillers in the market and the development of diversified functions, users often can not judge the quality of chiller products.
Today, Grand Packing will tell you how to distinguish the advantages and disadvantages of chillers.
Generally speaking, we can distinguish the advantages and disadvantages of chillers from the following aspects:
I. Compressor
Compressor is the core part of the whole industrial chiller, its quality directly affects the quality of a machine, and even the length of its service life.The compressor is the basic source to ensure refrigeration. The compressor is used to increase the daily refrigeration pressure of the system, so that the refrigerant can circulate in the refrigeration system.Achieve that purpose of refrigeration.Common compressors are divided into three types: open, semi-enclosed and fully enclosed.
2. Expansion valve
The expansion valve is a throttling and pressure reducing component in the industrial chiller system, which reduces the condensation pressure of the refrigerant to the evaporation pressure. Therefore, it is an essential component in the refrigeration system. It is called the four major components of the refrigeration system together with the compressor, evaporator and condenser.
3. Evaporator
When the liquid Freon of the refrigeration system enters the expansion valve and is sent to the evaporator, it belongs to the vaporization process. At this time, it needs to absorb a large amount of heat, so that the temperature of the cooled medium is gradually reduced, and the effect of refrigeration and cooling has been achieved.According to the type of medium to be cooled, there are two main types: evaporators for cooling liquid and evaporators for cooling air.
4. Condenser
The high temperature and high pressure Freon in the refrigeration system enters the condenser after coming out of the compressor, releases a large amount of heat to the cooling medium, and is cooled and liquefied.In that condense, the heat released by the refrigerant is carry away by the cooling water.
