Heat Pumps

Heat pumps are being in use for several decades in refrigerators and air conditioning units. It is a well insulated unit that move heat from one "space A" to " space B. When heat is removed from space 'A' and space ' A' becomes cool and 'B' becomes hot. Based on the need and space 'A' can be made cool or hot. This concept is in use since 1850 when James Harrison made the first refrigerator. The ground source heat pump works on the same principle. The ground source heat pumps (GSHP) are also known under several names: Ground Heat Pumps-GHP, Ground Coupled Heat Pump-GCHP, Groundwater Heat Pump-GWHP.The basic principle on which the GHP works is "refrigeration cycle". The refrigerant carries the heat from one "space" to another. The heat pump's process can be reversed. The earth is the main source and sink of heat. In winters it provides heat and summers it takes the heat.
