What is the refrigeration equipment? What are the components of the refrigeration equipment system?
Compressor: The compressor is the core component of the entire refrigeration system and is the power source for refrigerant compression. Its function is to convert electrical energy input into mechanical energy, inhale, compress and transport refrigerant vapor to drive the cycle.
Condenser: During cooling, the condenser acts as a source of heat and condensing refrigerant. After the high-pressure superheated steam exiting the refrigeration compressor enters the condenser, all of the heat absorbed during operation is transferred to the surrounding medium (water or air), including heat absorbed from the evaporator, refrigeration compressor, and piping. The refrigerant condenses again into a liquid under high pressure.
Dry filter: Water and dirt must be prevented from entering the refrigeration cycle. The water comes mainly from the small amount of water contained in the newly added refrigerant and lubricating oil, or from the air entering the system during overhaul. If the water in the system is not removed, as the refrigerant passes through the throttle (thermal expansion valve or capillary), the water sometimes solidifies into ice due to pressure and temperature drops, blocking the passage and affecting the normal operation of the refrigeration unit. Therefore, a dry filter must be installed in the refrigeration system.
Throttle: A thermal expansion valve (or capillary) is installed in the refrigeration unit between the dry filter and the evaporator, and the thermal expansion valve is wrapped at the evaporator outlet. Its main function is to throttle the high-pressure room temperature refrigerant liquid and decompress it when it flows through the superheat expansion valve, and convert it into low-temperature low-pressure refrigerant wet steam (mostly liquid, a small part of steam) into the evaporator, evaporation and absorption evaporator The heat in the heat reaches the purpose of cooling and cooling.
Evaporator: An evaporator is a heat exchanger that relies on the evaporation (actual boiling) of the refrigerant liquid to absorb heat from the cooling medium. Its function in the cooling system is to absorb heat. In order to ensure a stable and long-lasting evaporation process, the evaporation gas must be continuously pumped through a refrigeration compressor to maintain a certain evaporation pressure.
Refrigerants: Most industrial coolers used in modern industry use R22 or R407C as a refrigerant. A refrigerant is a flowing working medium in a refrigeration system. Its main function is to carry heat and achieve heat absorption and release when the state changes.
