What is a Chiller?
Refrigerant systems known as chillers are used to cool buildings, machinery, operations, and industrial chemicals in both residential and commercial settings.
It is a cooling system that removes heat by circulating a refrigerant that absorbs heat and then releases it through a series of mechanisms. The compressor, condenser, expansion valve, and evaporator are a chiller’s primary parts. They cooperate to transfer a refrigerant that reduces heat from a procedure, activity, or area.
How Does it Work?
Using water from an external cooling tower, water-cooled chillers dissipate heat from a gaseous refrigerant in the condenser before it transitions into a liquid.
Although there are two extra steps, the overall process of cooling refrigerants in water-cooled chillers is similar to that of air-cooled ones. First, the heat of the refrigerant is transferred to the condenser water, and then, to complete the process, the warm condenser water is pumped into cooling water to disperse the heat into the surrounding air. Water-cooled chillers are often more effective. Due to water’s enormous heat capacity, using it to reject heat is both substantially more energy efficient and effective than using air to blow across a heated surface. Furthermore, water-cooled chillers often have a longer lifespan than air-cooled ones.
Types of Water Chiller System
1. Air-cooled Water Chiller
Condensers on these water chillers are made to transfer heat from the refrigerant to the surrounding air. The condensing medium is air, which they utilize. The simplicity and inexpensive cost of air-cooled water chillers are advantages. Without the need for extra infrastructures like cooling water supply lines and cooling towers, they can be deployed as standalone units.
2. Water-cooled Water Chiller
Water serves as the condensing medium in water-cooled water chillers, as the name suggests. In large industrial plants with easy access to cooling water, water-cooled chillers are used. Compared to air-cooled models, the condenser receives cooling at a significantly higher efficiency.
3. Centrifugal Water Chiller
A centrifugal-type compressor is used in the refrigeration system of a centrifugal water chiller. The kinetic energy of the gas is increased by a centrifugal compressor, which raises the pressure. To transform the fluid’s kinetic energy into potential energy in the form of static pressure, the fluid is then slowed down. They fall into the dynamic-type compressor category due to their operating philosophy.
