Water-Cold Chiller AC: Advantages and Disadvantages

Chillers are used in a variety of sectors. They keep medical machines working smoothly and milk chilled until it is delivered to markets. They help in the pharmaceutical and brewing industries, as well as meat and poultry processing. If you need a chiller AC for your business, one of the first decisions you’ll have to make is whether you want an air-cooled or a water-cooled chiller AC. Here are the key advantages and disadvantages of water-cooled chillers to help you with your research.

Advantages

Longer Life Expectancy

Water-cooled chillers don’t need to be replaced as frequently as air-cooled chillers. They are less vulnerable because they are not exposed to outside elements such as rain, snow, ice, and heat.

Activity in Silence

Water-cooled chillers are quieter than air-cooled chillers, which have ducts and vents that make noise. The water moves through the system does not cause the same loud expansion and contraction that air-cooled chillers do. Quiet operation is especially crucial in places like hospitals and schools, where noise can cause occupants to become restless.

Efficiency in Energy

Water-cooled chillers have a film coefficient that is 10 to 100 times better than air-cooled chillers. This means that water-cooled chillers are more efficient in transferring heat. Businesses save money on electricity as a result of this.

No Open Space Needed

To work, air-cooled chillers must be kept outside in an open area with enough fresh air. Water-cooled chillers are installed inside buildings, making them excellent for businesses with limited outside areas.

Safety

Instead of harmful chemicals, water-cooled chillers employ water as a refrigerant. People who come into contact with them will be safer as a result of this.

Disadvantages

More Expensive

Because cooling towers and condenser water pumps are not required, air-cooled chillers are less expensive than water-cooled chillers. Many organizations, however, believe that the longer lifespan and cheaper energy costs of water-cooled chillers make the initial investment worthwhile.

Basic Maintainance

Water-cooled chillers require greater maintenance because they contain more parts. Periodic inspections, water treatment to eliminate pollution, and frequent cleaning of the chiller’s gear should all be planned for. Additional maintenance also means more chiller availability. Because there are more parts on a machine, the more things that might go wrong, water-cooled chillers are more likely to require repairs than air-cooled chillers.

Installation Is Difficult

Water-cooled chillers have more parts, which makes installation more difficult. This could result in increased labor expenses when installing water-cooled chillers vs air-cooled chillers.

A mechanical Room is required.

A mechanical room is required in order to accommodate a water-cooled chiller. This is to confirm that the chiller’s cooling tower and other components are working properly.

Not Recommended for Drought-Affected Areas

Water-cooled chillers aren’t ideal in areas where water is scarce because they utilize a lot of it. With the usage of a water-cooled chiller AC, companies that pay for water should expect their bills to climb. Water-cooled chiller AC use is also restricted in some drought-stricken locations.

In Humidity, Less Efficient

Although water-cooled chillers are more efficient than air-cooled chiller AC in general, they will perform worse under warm weather. Because humidity elevates the wet-bulb temperature, which reflects how well water absorbs heat, this is the case. In humid situations, water-cooled chillers can make building occupants feel cold and dizzy.
