A chiller can be regarded a cooling system that cools materials down by removing heat from a liquid via a vapor-compression or absorption refrigeration cycle. The liquid gets circulated through a heat exchanger to cool equipment. In a chiller system, there is always a liquid working as a refrigerant going through the heat exchanger in order to transfer the heat energy. When the heat gets absorbed by the liquid, materials get chilled.

What Are the Main Components of a Chiller?

The chiller consists of four main components, including compressor, evaporator, condenser, and expansion valve, which work together to achieve the cooling and heating effect of the unit.

The compressor is the core component of the entire refrigeration system, which is also the source of power for refrigerant compression. The condenser plays the role of outputting heat energy and allowing the refrigerant to condense. The evaporator is a heat exchange device that relies on the evaporation of refrigerant liquid (actually boiling) to absorb the heat of the cooled medium. The expansion valve is both a flow regulating valve and a throttle valve in the refrigeration equipment in the chiller refrigeration system.

What Are the Two Basic Types of Chillers?

Generally, there are two basic types of chillers in terms of the cooling principle, which are water cooled chillers and air cooled chillers. Even though these two types of chillers have different cooling principles, they have the similar components, which are the evaporator, the compressor, the condenser and the expansion valve. Different types of chillers are used in different fields or different applications, so choose the proper chillers correctly when use them.

What is the Working Principle of a Chiller?

As there are various kinds of chillers, they have the same working principle. A chiller system is about transferring and taking in the heating energy. Hence, the transformation of heating energy is the basic working principle of a chiller system. In the working process of a chiller system, the heating energy get transferred from a kind of material or any other thing to a middle solvent or substance. In the process of transferring heating energy, the pointed materials’ heating energy get absorbed and turned into a cold situation, which is the destination of a chiller system.

What Are the Different Types of Refrigeration Compressors?

Compressors can be divided into rotary compressors, axial compressors, jet compressors and screw compressors and other types, of which the most widely used is reciprocating (piston) compressors according to the structure of multiple compressors.
