You can opt for one of the numerous types of compressors to increase the pressure and speed of refrigerant flow.

3)  Absorption of Heat

Here, the refrigerant moving at high velocity under high pressure will flow over tubes and pipes that contain hot water.

The tubes and pipes have hot water which contains the heat that was released by the coolant you intend to cool.

So, you will increase the residence time of the refrigerant within the evaporator as it absorbs the heat.

It will change state from liquid to gas due to the absorption of heat from the hot water.

4) Elimination of Heat

As soon as the refrigerant has enough heat load, it will flow from the evaporator straight to the condenser.

While in the condenser, it will encounter a stream of cool water or air which will eliminate the heat.

Your choice of coolant chiller will determine the type of chiller which can either be air or water.

The refrigerant will release the heat into the flowing water or air and then condense it back to a liquid state.

5) Refrigerant Setting

With the same velocity, the liquid refrigerant will flow to the expansion valve which restores it to its original settings.

Implying that, you will set the expansion valve to reduce the speed and pressure of the refrigerant accordingly.

It will then deliver the refrigerant straight to the compressor in specific quantities and the whole process begins once again.
