Abstract: Water condensed from the air drawn over the refrigeration unit of an air conditioning system is collected and directed into a first chamber of a dual chamber reservoir where it is pumped through heat exchanger coils. The heat exchanger coils are placed upstream from the condenser and can be in thermally conductive contact with a fibrous heat exchanging air filter placed across the air intake port of the air-cooled refrigerant condenser for the system. The chilled condensate lowers the air intake temperature and if placed in thermally conductive contact with the filter, cools the filter also. The condensate is then directed to the top of the filter where it is poured onto the filter and allowed to flow down the fibrous surface, thereby evaporating. The latent heat of vaporization in this process further cools the filter which in turn, further reduces the air intake temperature.
