CH-89-20-4 -- Design Considerations for Ground and Water Source Heat Pumps in Southern Climates ✓ Most Recent

Ground and water source heat pump systems have very attractive performance characteristics when properly designed and installed. These systems typically consist of a water-to-air or water-to-water heat pump linked to a closed-loop vertical or horizontal ground-coupling, an openg round water loop, or a surface water loop. This paper discusses SYstem performance characteristics, component selection procedures presently being used, and future possibilities for improved efficiency and reliability. Emphasis placed on requirements of residential and light commercial applications in southern climates.

Optimum designs require proper matching of the heat pump unit to the water circulation system, the building space heating/cooling load, and water heating requirements. General trends resulting from system and component choices will be discussed. Water heating methods with these heat pumps will be considered.
