The low temperature chiller still uses a larger amount of cooling water equipment in our usual refrigeration equipment. When using it, you must first understand the principle of the low-temperature chiller and various accessories to better operate the low-temperature chiller.
The low temperature chiller
is a water-cooled cooling device that can provide a certain constant temperature, constant current and constant pressure refrigeration equipment. It uses the water tank in the machine to inject a proper amount of water, and the water is cooled by the refrigeration system, and then the cooling water is sent by the water pump. In the equipment that needs to be cooled, the chilled water takes the heat away from the temperature and the water flows to the water tank to achieve a cooling effect.
Generally speaking, the low temperature chiller is a relatively economical equipment. Generally, the refrigerant circulation system, the electric control system and the water circulation system complement each other through a condenser, a compressor, a thermal expansion valve, an evaporator, a liquid reservoir, and a drying machine. Filter, refrigerant, etc.
When the low temperature chiller is in use, the condenser can act as a heat output. Once the high pressure gas discharged from the compressor enters the condenser, it can absorb its heat and transfer other heat in the pipeline. Take away the surrounding media.
The compressor is very important in the low temperature chiller. It belongs to the core part and can convert electrical energy into mechanical energy and compress refrigerant. It is also closely related to the operation of other accessories.
In the low-temperature chiller, the thermal expansion valve regulates the flow rate, and is also a throttle valve in the refrigeration equipment, which allows the high-pressure normal temperature refrigerant liquid to be throttled and depressurized through the thermal expansion valve, and becomes a low-temperature low-pressure steam to enter the evaporator gas. Heat absorption to achieve the purpose of cooling.
Of course, the evaporator is also a heat exchange device that uses the refrigerant to evaporate to the low temperature chiller to absorb heat. In addition, in the relatively small low-temperature chiller, the drying filter is also necessary, and it is necessary to prevent some other substances from entering the refrigeration system!
Therefore, everyone should take a good look before using the low-temperature chiller. After all, there are more knowledge points. You can take a look at it!
