How Does the Water-Cooled Screw Chiller Work?

With the knowledge of the main components in place, you can now understand the working principles of the machine better.

Here is a step-by-step process that details how the water-cooled screw chillers work.

· Release of the Refrigerant

You will begin the process by activating the water-cooled chillers after a thorough inspection of the machine.

As soon as you press the start button, the refrigerants will move from the refrigerant cylinders to the condensers.

With the help of a propeller or fan, the refrigerant will flow straight to the screw compressor of the machine.

· Compression of the Refrigerant

Secondly, the screw compressors which consist of male and female compressors will compress the refrigerant.

The screw compressors rotate in helical movement thus compressing the refrigerant flowing between the teeth of the screw compressors.

At this point, the refrigerant will decrease in volume and increase in pressure as it flows to the evaporator.

· Collection of Heat

Once the refrigerant reaches the evaporator, it will collect heat from the evaporator and change its form to gas.

In the evaporator, we have pipes that deliver hot water that circulates through the system collecting heat.

The heat will change the refrigerant into gas and also allow the flowing water to cool off and lose the heat.

After that, the gaseous state refrigerant will flow at the same velocity and pressure to the condenser.

· Elimination of Heat

This is the part where the cooling water in the water-cooled screw chiller will kick in and collect the heat.

As soon as the gaseous refrigerant reaches the condenser, it will flow into a reflux tank which increases its residence time.

While in the reflux tank, cool water will flow over the reflux tank and collect the heat from the gaseous refrigerant.

In the process of heat collection, the water-cooled screw chillers will condense the refrigerant back to the liquid state.

The cooling water will warm up and take the heat away to the cooling water tower to dispose of it adequately.

· Restoration of the Refrigerant

Finally, the refrigerant will flow back to the expansion valve where it will restore the refrigerant to normal.

The expansion valve will reduce the pressure and increase the volume of the refrigerant.

It will, therefore, proceed back to the compressor for further compression and the process continues.

What is the Difference Between the Water-Cooled Screw Chiller and Water-Cooled Reciprocal Chillers?

The main difference between the water-cooled screw chillers and reciprocal chillers is the type of compressors.

Water-cooled screw chillers use screw compressors while water-cooled reciprocal compressors use reciprocal compressors.

The difference between the two is in the working principles of the screw and reciprocal compressors.

Apart from that, all the other factors are similar including the overall working principle and the components.
