Abstract
A heat transfer system including mechanical and electrical components for use with a mechanical air conditioning system to enable the system to efficiently reject heat to a water source, such as a pool or spa while simultaneously cooling an interior space. The air conditioning system incorporates three primary heat transfer coils in a mechanical refrigeration cycle to provide comfort cooling to an interior space while rejecting heat to either the atmosphere or a water source, such as a swimming pool. In an alternate heat pump embodiment, the system is capable of operating in an additional mode to absorb heat from the atmosphere and reject heat to the interior space.
