Air Cooled Screw Chiller

Air Cooled Screw Chiller

The main purpose of each component of the refrigeration system of air cooled screw chiller

1. Screw compressor

It is the power of the refrigeration system of the air cooled screw chiller, which is equivalent to the “heart” of the human body. Its main function is to extract the vapor in the evaporator in time, maintain low temperature and low pressure, and increase the pressure and temperature of the refrigerant vapor through compression, creating conditions for the heat of the refrigerant vapor to transfer to the external environment medium.

2. Condenser

air cooled screw chiller is a finned condenser. The condenser is a heat exchange device. Its function is to take away the heat of the high-temperature and high-pressure steam from the refrigeration compressor through the ambient cooling medium. The ambient cooling medium here is generally air or water. Here I want to emphasize that if you want to have a good cooling effect, you must dissipate a certain amount of heat, which requires a large enough condenser area!

3. Throttling element

Because the high-pressure and normal-temperature refrigerant liquid cannot be directly sent into the low-temperature and low-pressure evaporator, therefore, it is necessary to reduce the pressure of the refrigerant liquid and lower the temperature of the refrigerant liquid, so it is necessary to obtain a low-temperature and low-pressure refrigerant through a throttling element, and then Sent to the evaporator to absorb heat and vaporize. Then our throttling element is to choose Danfoss or Emerson’s thermal expansion valve.

4. Evaporator

Like the condenser, the evaporator is also a heat exchange device. It evaporates the throttling low-temperature and low-pressure refrigerant liquid into vapor, absorbs the heat of the cooled medium, and reduces the temperature of the cooled medium to provide low-temperature cooling. Chilled water for refrigeration purposes. The evaporator is the same as the condenser, and the evaporator area is large enough to work well.

The above is the purpose of the main components of the refrigeration system of the air cooled screw chiller, and its refrigeration work mainly depends on these four major components. Therefore, when you buy an air cooled screw chiller, you should pay attention to these four main components.
