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
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.
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
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.
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.
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.
