Summary:Basic composition of the refrigeration system

Compressor: The compressor is the core component of the entire refrigeration system and the source of refrigerant compression. Its function is to convert the input electrical energy into mechanical energy to compress the refrigerant.

Evaporator: An evaporator is a heat exchange device that relies on the evaporation (actually boiling) of a refrigerant liquid to absorb the heat of the cooled medium. Its function in the refrigeration system is to absorb heat (or output cooling). In order to ensure a stable and long-lasting evaporation process, the vaporized gas must be continuously withdrawn by a refrigeration compressor to maintain a certain evaporation pressure.

Condenser: The condenser acts to output thermal energy and condense the refrigerant during the refrigeration process. After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, all the heat absorbed in the working process, including the heat absorbed from the evaporator and the refrigeration compressor and in the pipeline, is transferred to the surrounding medium (water or Air) takes away; the refrigerant high pressure superheated vapor recondenses into a liquid. (Depending on the cooling medium and cooling method, the condensers can be divided into three categories: water-cooled condensers, air-cooled condensers, and evaporative condensers.)

Thermal expansion valve: The thermal expansion valve is both a flow regulating valve in the refrigeration system and a throttle valve in the refrigeration device. It is installed between the drying filter and the evaporator in the refrigeration device, and its temperature sensing package is bandaged. At the exit of the evaporator. Its main function is to reduce the pressure of the high-pressure normal temperature refrigerant liquid when flowing through the thermal expansion valve, and become a low-temperature low-pressure refrigerant wet steam (mostly liquid, a small part is steam) enters the evaporator and vaporizes in the evaporator. It absorbs heat and achieves the purpose of cooling and cooling.

Drying filter: moisture and dirt (oil, iron filings, copper filings) must be prevented from entering the refrigeration cycle. The source of moisture is mainly the amount of water contained in the newly added refrigerant and lubricating oil, or due to the maintenance system. The moisture that comes when the air enters. If the moisture in the system is not cleaned out, when the refrigerant passes through the throttle valve (thermal expansion valve or capillary), the moisture will solidify into ice due to the pressure and temperature drop, which will block the passage and affect the normal operation of the refrigeration unit. Therefore, a dry filter must be installed in the refrigeration system.

Reservoir: The reservoir is installed after the condenser and is in direct communication with the drain of the condenser. The refrigerant liquid in the condenser should flow unimpeded into the reservoir so that the cooling area of ​​the condenser can be fully utilized. On the other hand, when the heat load of the evaporator changes, the required amount of the refrigerant liquid also changes, and at that time, the reservoir functions to regulate and store the refrigerant. For small refrigeration systems, instead of a liquid reservoir, a condenser is used to regulate and store the refrigerant.

Refrigerants: Most industrial chillers used in modern industry use R22 or R12 as refrigerants. Refrigerant is a working fluid in a refrigeration system. Its main function is to carry heat and achieve heat absorption and heat release when the state changes.
