A heat transfer system for use in cooling and dehumidifying an interior space while rejecting heat to several alternative sources. The system incorporates three primary heat transfer coils in a mechanical refrigeration cycle to provide comfort cooling to an interior space while rejecting heat to one of two primary condensing mediums. In addition the heat transfer system of the present invention functions by transferring heat from the atmosphere to a pool, thereby functioning as a pool heater. In a first operating mode heat transferred from an interior space to the ambient atmosphere. In a second operating mode heat is transferred from an interior space to pool water. In a third operating mode heat is transferred from the ambient atmosphere to pool water. A refrigerant-to-water heat exchanger is disclosed having a gas trap for isolating corrosive gases from the metallic heat exchanger components, and further including a sacrificial zinc anode for corrosion protection. A novel control system is disclosed using first and second desired pool water temperature set-points for maximizing system efficiency.
