basic structure

The industrial chiller unit consists of accessories such as a compressor, condenser, evaporator, expansion valve, etc.

Compressor: In industrial chiller systems, the compressor is the power that ensures refrigeration. The compressor is used to increase the pressure of the refrigerant in the system, allowing the refrigerant to circulate in the refrigeration system to achieve the purpose of refrigeration.
Condenser: The high-temperature and high-pressure Freon in the refrigeration system enters the condenser after coming out of the compressor, releasing a large amount of heat into the cooling medium, which is then cooled and liquefied.
Evaporator: When the Freon liquid in the refrigeration system enters the expansion valve for throttling and is sent to the evaporator, it belongs to the evaporation process. At this point, it needs to absorb a large amount of heat to gradually reduce the valence and mass temperature, in order to achieve refrigeration and cooling effects.
Expansion Valve: In the refrigerant system flowchart of industrial chillers, we found a small section between the outlet of the condenser and the inlet of the evaporator, called a thermal expansion valve. It is a throttling and pressure reducing component used to reduce the condensation pressure of the refrigerant to the evaporation pressure. Therefore, its role in refrigeration systems is crucial. It is connected to the refrigeration compressor, evaporator, and condenser. It is also known as the four components of a refrigeration system.
Other attachments: including drying filters and high and low pressure controllers. The drying filter is not removable. The internal structure adopts a molecular sieve structure, which can remove a small amount of impurities and water in the pipeline, thereby purifying the system. High pressure and low pressure controllers play a protective role in refrigeration systems.

Direct Cooled Chiller

Temperature control range: -120 ℃ to -10 ℃

The refrigerant in the refrigeration system is directly output and evaporated into the target control element (heat exchanger) for heat exchange, thereby cooling the target control object. Having heat exchange capacity is generally more than 5 times higher than that of fluid (gas) transported into a heat exchanger, making it particularly suitable for applications with small heat exchange areas and large heat exchange capacity. It can also be used as gas capture by directly passing refrigerant into the collector for evaporation, and quickly capturing gas in the space through the surface condensation effect of the collector.

Direct Cryogenic Chiller

Temperature control range: -150 ℃ to -110 ℃

Application Principle: In high vacuum environments where oil diffusion pumps are used, there is a certain amount of residual gas, over 80% of which is water vapor. Oil vapor and other high boiling steam, but their ability to remove residual gases is low, the time is long, and all residual gases are also sources of pollution to the workpiece, which affects the production and quality of the product.

Chillers Type

Air Cooling /Cooled Chiller

Does not need to be connected to the cooling tower and is suitable for environments with low impurity content. Impurities can easily mix in the cold water tower, and dust can cause blockage in the cooling water circulation circuit, leading to a decrease in cooling capacity.
The air-cooled chiller is most suitable for areas with poor water quality, which can save other accessories such as cold water towers.
The use of large capacity condensers makes operation easier and more convenient.
The footprint is greatly reduced, making installation very convenient.
The air-cooled chiller unit adopts an upper air outlet design.
