What are the Working Principles of Scroll Chiller?

To better understand the Scroll Chiller, you need to know the principles of its working.

Let’s see how a Scroll Chiller works!

A Scroll Chiller is a water cooling machine. You can also use it to cool down the liquids and dehumidify the air around them.

It works upon the fundamental principles of evaporation and Condensation.

The Scroll Chiller system uses three interlinked systems.

• Refrigeration cycle
• Water circulation process
• Electrical control system

According to these interlinked systems, the water or liquid circulates from the chiller process.

In this way, cooled liquid removes the heat from the process, and the warm fluid returns to the chiller.

The process water is a source by which heat transfers from the process to the chiller.

During this process, The Scroll Chiller uses a chemical material known as refrigerant. There are different kinds of refrigerants but they all work on the same principle of compression.

Refrigerant processes the liquid into gaseous form and then condenses into liquid form, through the expansion valve.

This process is known as a refrigerant cycle.

A refrigerant cycle includes the following components:

1. Condenser

The purpose of the condenser is to release heat and condense the refrigerant.

1. Cistern

The cistern works as a reservoir in the condenser. It is connected to the drainpipe of the chiller directly.

The liquid refrigerant continuously flows into the receiver to completely utilize the cooling place of the condenser.

1. Dry Filter

You need to install the drying filter in the refrigeration system. It prevents moisture and dirt in the refrigeration cycle.

1. Thermal Expansion Valve

A thermal expansion valve plays an important role to control the flow of refrigerant between the condenser and the evaporator.

1. Evaporator

An evaporator is a device in a chiller. It is used to convert liquids into their gaseous state.

1. Refrigerant

Refrigerant is a chemical compound used in a refrigeration cycle of Scroll Chiller. It works on the principle of compression.

The glycol refrigerants are the best refrigerant for the Scroll Chiller. You can also use a mixture of glycol refrigerant and water.

R12 and R22 are also best for Scroll Chiller.

Scroll Chiller has an electrical control system, also known as a microcomputer control system; it’s possible to adjust the resulting cooling capacity and other functions automatically to meet your requirements.

That is how a Scroll Chiller works.
