What are Water Chillers?

Water chillers are refrigeration systems designed to cool water or a water-glycol mixture, which is then circulated through process equipment or machinery to absorb and dissipate heat. These chillers are crucial in maintaining the temperature stability required for various industrial processes, ensuring product quality, and preventing equipment overheating.

Types of Water Chillers

Air-Cooled Chillers: These chillers use air to cool the refrigerant in the condenser. They are generally easier to install and maintain, making them suitable for smaller facilities or locations with limited water supply.

Water-Cooled Chillers: These chillers use water to cool the refrigerant in the condenser. They are more efficient than air-cooled chillers and are ideal for larger facilities with access to a reliable water source.

Portable Chillers: These are compact, mobile units that can be easily moved to different locations within a facility. They are suitable for temporary cooling needs or smaller operations.

Central Chillers: These are large, centralized systems designed to provide cooling for entire facilities. They are typically used in large-scale industrial applications.

Working Principles of Water Chillers

Water chillers operate on the basic principles of refrigeration. The process involves the following steps:

Compression: The refrigerant gas is compressed by the compressor, increasing its temperature and pressure.

Condensation: The hot, high-pressure gas flows into the condenser, where it is cooled and condensed into a liquid.

Expansion: The liquid refrigerant passes through an expansion valve, which reduces its pressure and temperature.

Evaporation: The cold refrigerant enters the evaporator, where it absorbs heat from the water or water-glycol mixture, cooling it down.

Circulation: The chilled water is then circulated through the system to provide cooling where needed.

Applications of Water Chillers in the UK

Water chillers are used in a wide range of industries and applications in the UK, including:
