Heat Pumps for Heating and Cooling Horizontal loop system can be configured as straight, multiple or slinky arrangement. Single pipe ground loops are installed over relatively large open areas, free from hard rock or large boulders with sufficient soil depth. In an alternative arrangement, the single pipe can be doubled or quadrupled in multiple-layers. Multiple pipes placed close to each other are not as effective at gathering surrounding heat as are single tubes placed several feet apart. However, multiple pipes within a single trench can greatly reduce the amount of trenching required, and they often require more length of piping compared to a single layer loop. A variation of the multiple-layer horizontal loop is the coiled loop; generally called a ‘slinky’ collector. This loop can be placed either vertically in a trench or horizontally in an open pit. The spiral loop generally requires more total piping, typically 500 to 1,000 ft. per cooling ton, but less trenching than multiple-layer, horizontal loops. Horizontal earth loops will experience greater temperature variation between fall and spring compared to vertical earth loops. This allows the heat pump to achieve relatively high heating capacity and COPs in fall. However, both of these performance indices will decrease as winter progresses, and tend to be at or close to minimum in late winter or early spring. 35PDF Image | Heat Pumps for Heating and Cooling
