Water Chiller

Water Chiller

The water chiller is an appliance that cools water through a process called “chilling”. The process of chilling may involve either a heat-exchange or a refrigeration cycle.

Water chillers are often used in the food and beverage industry to maintain the temperature of cold drinks and in air conditioning systems to cool air.


What are Water Chillers?

A water chiller is an appliance that cools and condenses water vapor to a liquid. The common types of cooling techniques used in a water chiller are:

  • Air cooling
  • Evaporative cooling
  • Water cooling

The most popular type of evaporative cooler is the swamp cooler which relies on the principle of heat transfer by evaporation and convection. The swamp cooler works on the principle that hot air rises and cold air falls

How does a Water Chiller Work?

A water chiller is a machine that cools the water used in air conditioning systems.
A water chiller works by using a refrigerant that is pumped through a series of coils. These coils are submerged in a tank of cold water and the refrigerant absorbs heat from the water. The refrigerant then passes this heat on to the cooling coils which are inside an air-conditioning system, and this process cools the air-conditioning system


Types of Water Chillers

Heat Exchangers

These chillers usually have coils that are submerged in a tank of cold water, typically at about 40 degrees Fahrenheit (4 degrees Celsius). They work by exchanging heat from the hot fluid with the colder one.

Refrigerant Cycle

These chillers use refrigerants such as Freon to chill the fluid
