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.
Claims14
A water to air heat pump comprising a first heat exchanger including a coil and means for passing air over said coil;
- a second heat exchanger including a coil and a jacket enclosing said coil, said jacket having an inlet for receiving water from an external source and an outlet for discharging said water back to said source, said water being continuously circulated through said jacket and over said coil;
- conduit means for circulating a heat exchange fluid between said coils, said first heat exchanger adapted to act as an evaporator and evaporate said fluid and cool said air, and said second heat exchanger adapted to act as a condenser and condense said fluid;
- means for collecting the condensate from said air at said first heat exchanger;
- and means for passing said condensate to said jacket for mixing with said water and circulating over the coil associated with said second heat exchanger.
A water to air heat pump comprising a first heat exchanger including a coil and means for passing air over said coil;
- a second heat exchanger including a coil and a jacket enclosing said coil for circulating water over said coil;
- conduit means for circulating a heat echanger fluid between said coils, said first heat exchanger adapted to act as an evaporator and evaporate said fluid and cool said air, and said second heat exchanger adapted to act as a condenser and condense said fluid;
- means for collecting the condensate from said air at said first heat exchanger;
- means for passing said condensate to said jacket for mixing with said water and circulating over the coil associated with said second heat exchanger;
- and valve means associated with said passing means for preventing the flow of condensate from said jacket to said condensate collecting means.
A water to air heat pump comprising an evaporator including a coil and means for passing air over said coil, a condenser including a coil and a jacket enclosing said coil for circulating water over said coil, a compressor, conduit means for passing a heat exchange fluid from said condenser to said evaporator where said fluid is evaporated and said air is cooled, conduit means for passing the evaporated fluid from said evaporator to said compressor for compressing the fluid, conduit means for passing said compressed fluid from said compressor directly to said condenser where it is condensed by said water, means for collecting the condensate from air at said evaporator, and means for passing said latter condensate to said jacket for mixing with said water and circulating over the coil associated with said condenser.
