Evaporative condenser, also known as evaporative cooling and cooling (condenser), is a kind of equipment that absorbs the heat of the high-temperature gaseous refrigerant in the coil when the spray water outside the coil is partially evaporated, so that the refrigerant in the tube is gradually cooled from the gaseous state to the liquid state. Condensing temperatures within a wet-bulb design temperature of 8.3°C are very practical and economical, with the result that the compressor power is at least 10% less than other cooling tower/condenser systems, and 30% less power than air-cooled condenser systems, which is equivalent to the power consumed by the fans of the cooling tower/condenser system and is about 1/3 of the fan power of the same size air-cooled condenser fans.
