Pros and Cons of Water-Cooled Chillers

Advantages of Water-Cooled Chillers

Lifespan

Water-cooler chillers have longer lifespans than air-cooled chillers. This is because water-chillers aren't exposed to outdoor elements such as rain, snow, ice, or heat, thus they are more protected.

Quiet Operation

Water-cooler chillers operate quietly, while air-cooled chillers have ducts and vents, that may get quite noisy. The flow of water through the system is quite unnoticeable, compared to the contraction and expansion heard in air-cooled chillers.

This 'silence' or quiet operation is quite beneficial in environments such as hospitals, or schools, where noise can become a nuisance to the occupants.

Energy Efficiency

The film coefficient is 10 to 100 times better in water-cooled chillers vs air-cooled chillers. This is because water-cooled chillers transfer heat more efficiently, and this results in savings on energy costs for businesses.

No Open Space Needed

Water-cooled chillers are placed inside buildings, which makes them great for companies that don't have access to enough outdoor space. Air-cooled chillers stay outdoors and require an open space with fresh air to operate.

Safety

Water-cooled chillers use water as a refrigerant instead of toxic chemicals. This inevitably makes them safer for people who have frequent contact with them.

Disadvantages of Water-Cooled Chillers

Higher Cost

Air-cooled chillers are cheaper than water-cooled chillers since they don't require parts like cooling towers or condenser water pumps. However, many companies feel that the longer lifespan of water-chiller, and their savings on energy, more than makeup for the initial purchase price.

More Maintenance

Water-cooled chillers have more parts to take care of than air-cooled chillers, thus they require more maintenance. This means more periodic inspections, water treatments to remove impurities, and regular cleaning of the chiller's machinery.

Since water-cooled chillers have more parts than air-cooled chillers, they also likely require more frequent repairs than air-cooled chillers.

Complicated Installation

The additional parts that a water-chiller has, inevitably leads to a harder installation, than in the case of an air-cooled chiller. This may mean higher labor costs for installation, compared to the air-cooled chiller.

Mechanical Room

You need to have a mechanical room to house a water-cooled chiller, to ensure that it will function properly with its cooling tower and extra components.

Not Good for Drought-Stricken Areas

Water-chillers use quite a large amount of water, and thus they aren't suited for regions that have water shortages. The money spent on the water in these regions can leave you with a big pocket hole.

Less Efficient in Humidity

Though water-cooled chillers are mostly more efficient than air-cooled chillers, they won't operate as efficiently in humid environments. This is because humidity raises the wet-bulb temperature, which indicates how efficiently water absorbs heat. Water-cooled chillers in humid environments may also affect the workers, making them feel cold or clammy.

Chillers play an important role in many industries. They help keep medical machines running consistently, and they keep milk cool until it goes to markets. They assist in the pharmaceutical industry, the brewery industry, and in meat and poultry processing. If you're looking for a chiller for your business, one of the things you'll have to decide is whether you need an air-cooled chiller or a water-cooled chiller. To assist in your research, here are the main advantages and disadvantages of water cooled chillers.

Advantages of Water Cooled Chillers

Life expectancy longer

Water cooled chillers do not usually need to be replaced as often as air cooled chillers. They are unaffected by outdoor factors such as rain, snow, ice, and heat and make them less vulnerable.

Quiet operation

Although air cooled chillers have pipes and vents producing noise, water cooled chillers work quietly. Water flows through the system does not create the same noise in the air cooled cooler, causing expansion and contraction. Quiet operation is especially important in the environment where passengers and passengers may experience noise such as hospitals and schools.

In water-cooled chillers, the film factor is 10 to 100 times better than air-cooled chillers. This means that water-cooled refrigerators deliver heat more efficiently. The result of the business is to save energy costs.

Safety

It use water as a refrigerant instead of toxic chemicals. This makes items and people safer who comes in contact with it.

Disadvantage of Water cooled Chillers

Higher Cost

Air cooled chillers are cheaper than water cooled chillers because they don't require parts like cooling towers and condenser water pumps. Many companies feel that the longer lifespan and savings on energy costs make water-cooled chillers worth the initial high investment, however.

More Maintenance

Since water cooled chillers have more parts, they require more maintenance. Companies should prepare to pay for periodic inspections, water treatments to remove impurities, and regular cleaning of the chiller's machinery. More maintenance also means more downtime for the chiller. The more parts a machine has, the more things there are that can go wrong with the machine, which means water cooled chillers are more likely to require repairs than air cooled chillers.

Complicated Installation

The extra parts in water cooled chillers also make installation more of a hassle. This can mean higher labor costs for installation of water-cooled chillers as opposed to air-cooled chillers.

Requires Mechanical Room

Businesses need to have a mechanical room to house a water cooled chiller. This is to ensure that the chiller will function properly with its cooling tower and extra components.

Not Ideal For Drought-Stricken Areas

Since they use a good amount of water, water-cooled chillers aren't great in regions that have water shortages. Companies that pay water costs can expect these bills to rise with the use of a water-cooled chiller. Some drought-stricken areas also have restrictions on water-cooled chiller use.

Less Efficient in Humidity

Although water cooled chillers are overall more efficient than air-cooled chillers, they'll operate less efficiently in humid environments. This is because humidity raises the wet-bulb temperature, which indicates how efficiently water absorbs heat. Water-cooled chillers in humid environments may also make building occupants feel cold and clammy.
