Stainless Steel Water Cooler

A water cooler works by using a refrigerant to cool water. The refrigerant is compressed, causing it to become hot. The hot refrigerant is then passed through a condenser, which cools it down. The refrigerant is then squeezed through an expansion valve, which further decreases its temperature. The cooled gas in the water pipe is forced through a valve to make it even colder. When the refrigerant is in a gas form and is circulating in the pipes, it has the ability to absorb the heat away from the mineral water in the reservoir, leaving cool and refreshing water that is readily available.
