Abstract: The current invention provides an evaporative condensing system using an evaporative condenser heat exchanger having an outer surface. The heat exchanger has a superhydrophilic surface. A compressor is configured to circulate a working fluid through the heat exchanger. A water distribution system is adapted to deposit a controlled amount of water on the heat exchanger to absorb heat from the heat exchanger by evaporation of water from the heat exchanger. A collector is located below the heat exchanger to receive excess water from the heat exchanger and direct excess water to a drain and an air delivery system is provided to direct air over the heat exchanger. The water distribution system supplies water to the heat exchanger in sufficient quantity that the water wets the heat exchanger, keeps the heat exchanger wet along its length, and excess water remains to carry dissolved solids to the collector.
