What is the Working Principle of the Hydraulic Oil Chillers?

Just like the other chillers, you will similarly operate the hydraulic oil chillers.

Here is a step-by-step process that you can follow when operating the hydraulic oil chillers.

1) Compression Process

You will pass the refrigerant through the compressor of the hydraulic oil chiller which will compress the refrigerant.

It will compress the refrigerant thus increasing the pressure and speed of the refrigerants as it flows.

It will flow easily to the evaporator with very high speed and pressure.

2) Heat Absorption

Here, the refrigerant will pick up the heat from the system and change its state from liquid fluid to gas fluid.

After that, it will maintain the pressure and speed with the heat within and flow to the condenser.

It will also leave the flowing water within the evaporator tubes in a chilled manner to flow and collect more heat.

3) Heat Elimination

The refrigerant will go to the condenser unit where the air or water will eliminate the heat from the system.

It will dwell within the condenser for a while until the air or water eliminates all the heat from the system.

You will also realize that it will change its state from the gaseous state to the liquid state.

4) Pressure Reduction

Finally, the liquid refrigerant will pass through the expansion valve which will reduce the pressure.

The expansion with feeds the compressor with the refrigerant liquid as the whole process continues.
