How do Central Chillers Work? Know About the Process!

 

Industries that use heavy machinery producing heat, or the ones that use process fluids, always have a central chiller. Chiller helps them maintain the optimum temperature required to run the operations. It is vital to understand the working of the chiller, to decide which chiller works best for which industry. In this article, we will thoroughly explain what a chiller is? And how does it work?

What is Central Chiller?

A centralized cooling system under which the chiller provides cooling to the entire plant or building is called a central chiller. It is a better and a practical approach than installing chillers at each particular location.

How does Central Chiller work?

It works on the principle of vapor compression. The chiller maintains a continuous flow of coolant to and from the machinery. As it enters the processor, it cools the equipment up to the desired temperature level and comes out of the other area of the machinery. As it moves back, it extracts the heat along with it.

It then uses the vapor compression principle and circulates the refrigerant through a device known as an evaporator. The evaporator works as a heat exchanger by transferring the heat captured by the coolant during the flow into the refrigerant. After this transfer, the heat gets evaporated in the form of vapors, and the temperature of the coolant reduces. The refrigerant then flows into a compressor, where it isolates from the vapors and converts into the liquid form.

There are various types of chillers available in the market, and depending upon which type you get, the working may differ a little, but the basic idea remains the same. Different types of chillers are:

Water-cooled Chillers

These chillers circulate the water from the condenser again and again from a cooling tower to condense the refrigerator.

Air cooler Chillers

Air-cooled chillers depend on the air to cool the condenser down. It works fine in medium or small-scale enterprises.

Depending upon the requirement and size of the industry, one can choose the type of central chiller. However, it is significant to pay attention to the product quality and seller details to get efficient results!
