College of Product Knowledge: Water Coolers & Drinking Fountains
A modern day refrigeration system is based on a “closed-loop” concept, in which a refrigerant gas is continuously recirculated. The three basic components within this loop are a compressor to pressurize and circulate the fluid; an evaporator to absorb heat from the area surrounding it; and a condenser, to get rid of the heat taken on by the evaporator. As with any refrigeration system, each of these three basic components is found in a water cooler.
