    Compressor: Compressor is the core part of the whole refrigeration system, and also the source of the refrigerant compression power. Its role is to convert the input of electrical energy into mechanical energy, inhalation, compression and transport of refrigerant vapor, driving cycle. 

    Condenser: In the refrigeration process, the condenser acts as the output heat and the refrigerant condenses. After the high-pressure superheated vapor discharged from the refrigeration compressor enters the condenser, the total amount of heat absorbed in the work process, including the heat absorbed from the evaporator and the refrigeration compressor and in the pipe, is transferred to the surrounding medium (water or air), and the refrigerant high-pressure superheated vapor condenses into a liquid. 

    Drying filter: In the refrigeration cycle must prevent moisture and dirt and so on, the source of water is mainly the newly added refrigerant and lubricating oil contained in the micro-moisture, or due to overhaul the system when the air into the water. If the water in the system does not rule out the clean, when the refrigerant through the throttle valve (thermal expansion valve or capillary), due to pressure and temperature drop sometimes water branch solidified into ice, so that the channel obstruction, affecting the normal operation of refrigeration equipment. Therefore, a drying filter must be installed in the refrigeration system. 

    Throttle valve: Thermal expansion valve (or capillary) in the refrigeration equipment installed in the drying filter between the evaporator, the thermal expansion valve temperature is wrapped in the evaporator of the export department. Its main role is to make high-pressure refrigerant liquid flow through the thermal expansion valve when throttling buck, into low-temperature low-pressure refrigerant wet steam (mostly liquid, a small part of the steam) into the evaporator, evaporation in the evaporator endothermic, and to achieve cooling cooling purposes. 

    Evaporator: Evaporator is dependent on the refrigerant liquid evaporation (is actually boiling) to absorb the heat of the cooling medium of heat exchanger equipment. Its function in the refrigeration system is to absorb heat. In order to ensure the evaporation process can be stable and lasting, we must continuously use the refrigeration compressor to drain the evaporated gas to maintain a certain evaporation pressure. 

    Refrigerant: Most industrial chillers used in modern industry use R22 or R407C as refrigerants. Refrigerant is a refrigerant in the refrigeration system, its main role is to carry heat, and in the state of change to achieve endothermic and exothermic.
