Application and working principle of water-cooled chiller

The water-cooled chiller is a kind of LNEYA industrial low-temperature refrigerator in Wuxi Guanya. A single compressor can achieve -152 degrees Celsius cooling and cooling. Equipment power, size and temperature range can be customized.

1. Application

Refrigerators are widely used in industrial machinery processing, industrial cold processing assembly, petrochemical, fine chemical, and other high-tech industries.

2. Working principle

The gas-phase refrigerant is compressed into a high-temperature and high-pressure gas in the compressor, and then enters the condenser, where the refrigerant releases heat and condenses into a liquid. After the high-pressure liquid refrigerant is dewatered by the dryer, it passes through the expansion valve to save pressure and turns into low-pressure wet vapor, and then enters the evaporator to absorb heat and vaporize into low-pressure gas. The low-pressure gas enters the compressor to form a cycle. It can be seen that the reasons affecting the refrigerator are related to the compressor, condenser, expansion valve and evaporator, and in the refrigerant cycle, the oil-water separator is also a factor that affects the refrigeration effect. Let's do a brief analysis below. If the refrigerating unit is running and the inlet pressure is low and the equipment shuts down, if the amount of refrigerant is sufficient, the expansion valve will be blocked or frozen and the refrigerant will not enter the evaporator smoothly, and the inlet pressure will be low and an alarm will be shut down. And by checking whether there are impurities in the filter element of the dryer, it can be judged whether it is a fault of the expansion valve.

Product advantages of water-cooled chillers

1. Safety protection devices: Schneider and other well-known brand leakage circuit breakers, phase sequence open phase protectors, liquid level protectors, high and low voltage protectors, high temperature protectors and other safety protection devices

2. Intelligent computer control system: Siemens LCD display, display set temperature and control temperature, data communication interface, USB data export, Ethernet interface, etc.

3. International brand imported accessories: a full set of imported cold controls, international brand compressors and circulating pumps, to meet continuous high and low temperature continuous work, and protect the system from damage

4. Support customization: support customization, size and pressure customization can be made according to working conditions, positive pressure explosion-proof and isolation explosion-proof can be customized, and it can be widely used in dangerous explosive places.
