Water chillers are everywhere - they are used to air condition large industrial, commercial, and institutional facilities, and are used to lower the temperatures of all kinds of equipment, from robotic machinery to computer parts. They can also be used to cool down drinking water to pleasant levels, or to provide cooler water for ingredients in food. However, not many people actually know how they work, and knowing this can help you decide what kind you need, as well as the size. In this article, we'll take a look at some basic information regarding how chillers operate, as well as their use in daily life.
They function using four main parts - a compressor, an evaporator, a condenser, and a metering system. Since the purpose of a it is to remove heat from somewhere it is not wanted, like mechanical parts or liquids such as water, it sucks up heat using a refrigerant, a chemical that is very heat absorbent. The refrigerant then carries this heat to a condenser, where it is sent into the atmosphere by means of an air, evaporation, or water cooled heat exchanger. Sometimes cooling towers are attached to the heat exchanger if extra cooling power is needed. Once the refrigerant leaves the condenser, it is compressed (thus lowering its temperature) and sent back to absorb more heat.
