What Is a Medium & Low Temperature Water-Cooled Chiller Unit?

A water-cooled chiller unit is a refrigeration system that removes heat from a process or space using a vapor compression cycle. It uses water as the cooling medium to dissipate heat through a cooling tower or other water system.

Temperature Range:

• Medium temperature: 0°C to +10°C

• Low temperature: 0°C to -40°C

These units are widely used in industries that require precise and stable temperature control.

Working Principle

The operation of a water-cooled chiller unit involves several key components:

1. Compressor

Compresses refrigerant gas, increasing pressure and temperature.

2. Condenser

Transfers heat from refrigerant to cooling water.

3. Expansion Valve

Reduces refrigerant pressure, cooling it before entering the evaporator.

4. Evaporator

Absorbs heat from the environment or process, providing cooling.

5. Cooling Water System

Carries heat away from the condenser, often connected to a cooling tower.
