How does a water cooler work?
A water cooler works by a refrigerant that is compressed and circulated around the inside a sealed tank. There is usually a reservoir that holds the water and then there are pipes that run through this reservoir. The pipes then move super cooled fluid through it and cools the water in the reservoir.
Types A water cooler with a dispenser is a common product found in offices, hospitals, schools and homes. The water cooler offers an alternative to individual water bottles in the home and provides a sanitary water supply for large groups. While all water coolers provide chilled water, some models also provide both hot and cold water. Some models even provide water hot enough to use in soups or other instant foods. Aside from units that offer hot water, there are two main types of water coolers. Both bottled water coolers and bottleless water coolers provide a chilled water supply, but receive the water from a different source. Bottled water coolers are freestanding units that use a large plastic bottle to deliver water, and can be either bottom- or top-loaded. Bottleless water coolers hook up to the main water supply and utilize filtration services to provide clean, crisp-tasting water. Both types of water coolers have an on/off switch that controls the cooling and/or heating function
