How Industrial Water Chillers Work

Key Components Overview

It is important to know the main parts of industrial water chillers. Each part helps cool things down. Here are the main components you will see in most chillers:

• Compressor: This part takes in low-pressure refrigerant gas. It squeezes the gas. The gas gets hot and turns high-pressure.

• Condenser: The condenser cools the hot gas. It changes the gas into a high-pressure liquid. It does this by letting heat out to air or water.

• Evaporator: The evaporator lets the liquid refrigerant take in heat. The liquid turns into a low-pressure gas. This starts the cooling cycle again.

Factories use different types of chillers. Some common types are air-cooled chillers, water-cooled chillers, heavy-duty industrial chillers, absorption chillers, centrifugal chillers, scroll chillers, screw chillers, and reciprocating chillers. Each type works best for certain jobs. Air-cooled chillers use air to get rid of heat. These are good where water is not easy to find. Water-cooled chillers use cooling towers. They are good for big jobs. You can find chillers in many industries. Some examples are plastics, food and beverage, pharmaceuticals, and specialized cooling infrastructure.
