Air and water conditioner for indoor swimming pool

摘要

A method and apparatus for heating, cooling and dehumidifying the enclosure air from an indoor swimming pool while simultaneously heating or cooling the pool water. The system includes a water to air heat pump and an air to air heat pump with the water coil of the water to air heat pump arranged in heat exchange relation to the pool water and the air coil from the water to air heat pump, together with the two air coils from the air to air heat pump, arranged such that the enclosure air first passes over one air coil of the air to air heat pump, thereafter passes over the air coil of the water to air heat pump, and thereafter passes over the second air coil of the air to air heat pump prior to being reintroduced into the enclosure. Each heat pump includes a reversing valve so that the various coils may function as either an evaporator or a condenser with the result that heating or cooling of the pool water and heating, cooling and dehumidifying of the enclosure air may be selectively performed in accordance with the specific instantaneous demands of the pool water and the enclosure air.
