Analysis of accessories for low-temperature chillers
Low temperature chiller is still a commonly used cooling water device in our daily refrigeration equipment. Therefore, when using it, you need to first have a certain understanding of the principle and various components of the low-temperature chiller in order to operate it more efficiently.
Low temperature chiller is still a commonly used cooling water device in our daily refrigeration equipment. Therefore, when using it, you need to first have a certain understanding of the principle and various components of the low-temperature chiller in order to operate it more efficiently.
A low-temperature chiller is a water-cooled cooling device that can provide a certain temperature, constant current, and constant pressure refrigeration equipment. It uses an internal water tank to inject an appropriate amount of water, cools it through the refrigeration system, and then sends the cooling water into the equipment that needs to be cooled by a water pump. The chilled water carries away the heat, increases the temperature, and flows to the water tank, achieving a cooling effect.
Generally speaking, a low-temperature chiller is a relatively economical device, consisting of a refrigerant circulation system, an electrical control system, and a water circulation system that complement each other. It is composed of a condenser, compressor, thermal expansion valve, evaporator, accumulator, drying filter, refrigerant, and other components.
In the use of low-temperature chillers, the condenser can play a role in outputting heat. Once the high-pressure gas discharged from the compressor during operation enters the condenser, it can absorb its heat and transfer other heat in the pipeline to the surrounding medium for removal.
The compressor is a crucial component in low-temperature chillers, as it can convert electrical energy into mechanical energy, compress refrigerant, and is closely related to the operation of other accessories.
In low-temperature chillers, the thermal expansion valve is used to regulate the flow rate and is also a throttle valve in refrigeration equipment. It can allow high-pressure and room temperature refrigerant liquid to be throttled and depressurized through the thermal expansion valve, turning into low-temperature and low-pressure steam that enters the evaporator to vaporize and absorb heat, achieving the purpose of cooling.
Of course, the evaporator is also a heat exchange device that uses refrigerant evaporation to absorb heat in a low-temperature chiller. In addition, in relatively small low-temperature chillers, a drying filter is also necessary to prevent other substances from entering the refrigeration system!
