Ground Source Heat Pumps

Lale Valizade
Abstract—A heat pump is a device that is able to transfer heat from one fluid at a lower temperature to another at a higher temperature. Ground source heat pumps are generally classified by the type of ground loop. The coefficient of performance (COP) is used to define the heating performance of heat pumps. Both the COP and EER values are valid only at the specific test conditions used in the rating. A ground source pump could reach 450%, compared with an efficient gas boiler of 90% obviously this is a big difference. The cost of equipment, material and installation can be expensive, depending on the type of heat pump installation planned.

Index Terms—Heat Pump, ground source heat pumps, COP, air source heat pumps.
