Evaporator: An evaporator is a heat exchanger that relies on the evaporation (actual boiling) of IQF Freezing liquid to absorb the heat of the cooling medium. Its function in the cooling system is to absorb heat. In order to ensure a stable and lasting evaporation process, evaporation gas must be continuously pumped through a refrigeration compressor to maintain a certain evaporation pressure.
Condenser: During the refrigeration process, the condenser plays the role of outputting heat energy and condensing refrigerant. After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, all the heat absorbed in the working process is transferred to the surrounding medium (water or air), including the heat absorbed from the evaporator, refrigeration compressor and pipeline. The refrigerant condenses into liquid again under high pressure.
Throttle valve: thermal expansion valve (or capillary tube) is installed in quick freezing equipment between drying filter and evaporator, and thermal expansion valve is wrapped at the outlet of evaporator. Its main function is to throttle the high-pressure room-temperature refrigerant liquid and decompress it when it flows through the thermostatic expansion valve, converting it into low-temperature low-pressure refrigerant wet vapor (mostly liquid and a small part of vapor) entering the evaporator, evaporating and absorbing the heat in the evaporator, and achieving the purpose of cooling and cooling.
Drying filter small refrigerator equipment: water and dirt must be prevented from entering the refrigeration cycle. The water mainly comes from a small amount of water contained in newly added refrigerant and lubricating oil, or from air entering during system overhaul. If the water in the system is not removed, when the refrigerant passes through the throttle valve (thermostatic expansion valve or capillary tube), the water will sometimes solidify into ice due to the decrease of the pressure and temperature of the Quick Freezing Equipment, blocking the passage and affecting the normal operation of the refrigeration equipment. Therefore, a drying filter must be installed in the refrigeration system.
Compressor: The compressor is the core component of the whole refrigeration system and the power source for refrigerant compression. Its function is to convert electrical energy input into mechanical energy, suck, compress and transport refrigerant vapor, thus driving the cycle.
Refrigerant: Most industrial coolers used in modern industry use R22 or R407C as refrigerant. Refrigerant is the flowing working medium in the refrigeration system. Its main function is to carry heat and absorb and release heat when the state changes.
