Advantages and Disadvantages of Water Cooled Chiller

In modern industrial society, industrial chillers play an important role in various industries. For example, in the operation of CNC machine tools, industrial chillers reduce thermal deformation during processing through cooling. In the milk production process, industrial chillers are used to cool milk to avoid bacterial growth and ensure milk quality. In addition, industrial chillers play a key role in industries such as refrigerated food processing and beer production.

If your company is planning to buy a suitable chiller, then choosing between an air cooled or water cooled chiller will be the question you have to face. Through this article, you will learn more about the advantages and disadvantages of water cooled chillers to provide you with useful information

Advantages of water cooled chillers


●Higher heat dissipation efficiency: Compared to air cooled chillers, water cooled chillers absorb and transfer heat through water, which has better heat transfer properties than air, and therefore can more effectively remove heat from the cooled object.

●Higher energy efficiency: Compared to air cooled chillers, water cooled chillers utilize water to absorb and transfer heat, and water has better thermal conductivity than air. This means that water cooled chillers can dissipate more heat energy while consuming the same amount of energy.

●More stable cooling: Compared to air cooled chillers, water cooled chillers are less affected by ambient temperature and air mobility due to the use of water for cooling, which has a higher heat capacity and thermal stability. This means that they can provide stable cooling over a longer period and maintain stable temperatures even under high loads and long operating hours.

●Lower noise level: Compared to air cooled chillers, water cooled chillers have a lower noise level during operation. This is because air cooled chillers have fans that generate airflow noise and mechanical noise as they rotate, especially at high speeds. In contrast, water cooled chillers utilize water cooling circuits, where the flow of water is much quieter compared to the noise generated by fan rotation.

●Longer service life: Water cooled chillers have a longer service life than air-cooled chillers. This is because water-cooled chillers are usually installed in an indoor environment, whereas air cooled chillers need to be installed in a ventilated outdoor environment. This difference keeps water cooled chillers from being exposed to external environmental factors such as rain, snow, ice, and extreme heat. These environmental factors can cause damage to the chiller's critical components and increase the load on the equipment, thus reducing its durability.


●Higher refrigeration power: Typically, water cooled chillers are used in application scenarios with large refrigeration needs, where the compressor power is usually above 40 horsepower, while air cooled chillers are used in application scenarios with small refrigeration needs, where the compressor power is usually below 40 horsepower.

Disadvantages of water cooled chiller


●Installation is more complicated: water cooled chillers require additional components such as cooling water towers, pumps, and circulation lines. It requires reasonable design and layout of the chilled water tower, circulation piping, and other components. Therefore, compared with air cooled chillers, their installation is more complicated.

●Higher initial investment cost: Water cooled chillers themselves are more expensive than air cooled chillers, and require additional installation of the cooling water system, the installation cost is also relatively higher. Therefore, water cooled chillers have a higher initial investment cost than air cooled chillers.

●Not suitable for water-scarce areas: Water cooled chillers require a large amount of cooling water to remove and transfer heat during operation. Therefore, they are not suitable for use in areas where water is expensive and scarce, which can increase the operating costs and energy consumption of the equipment.
