When applied to light industrial systems, evaporative condensers provide lower condensing temperatures and compressor horsepower savings of up to 15 percent compared with traditional systems. In an evaporative condenser, refrigerant vapor is condensed in a coil, which is continually wetted on the outside by a recirculating water system. Air is circulated over the coil, causing a small portion of the recirculating water to evaporate. The evaporation removes heat from the vapor in the coil, causing it to condense.
