Spiral ground heat exchangers in heat pump applications play an important role in heating/cooling of buildings. Energy consumption of buildings is a significant factor in global environmental issues. One of the ways of supplying heating and cooling is using potential energy stored in the ground which is clean and sustainable. These types of systems are called ground source heat pump (GSHP) systems. The initial cost and efficiency of GSHP systems can be influenced by optimal design of ground heat exchangers (GHEs). Many parameters influencing thermal performance of spiral GHEs such as external major diameter of borehole, spacing, distance between each turns of spiral GHEs, etc. When we have a large application area, one spiral GHE is not enough for supplying heating or cooling demands of the building. In this case more than one GHE is needed to be embedded into the ground. When we have more than one GHE in ground, optimization of distance between them becomes an essential problem. Another important parameter which is highly affecting thermal performance of a GSHP system are thermal properties of ground. Before integrating a GSHP system to the building thermal properties of ground or soil should be determined.
