Abstract
A water to air heat pump employing an energy and condensate conservation system in which a heat exchange fluid is circulated between two heat exchangers with one normally operating as a condenser and the other normally operating as an evaporator. The condensate from the air passing over the evaporator coil is collected and is passed to the condenser for circulating over the condenser coil. The heat pump is adapted to operate in a reverse mode in which the functions of the heat exchangers are reversed and in which the circulation of the collected condensate to the condenser is terminated.
