What is Geothermal/ Ground Source Heat Pump(GSHP)?
Geothermal (or ground-source) use the natural heat storage capacity of the ground, rock, or ground water – instead of outside air – to provide heating, cooling and domestic hot water. Once temperatures below ground surface are relatively constant year round (well above the freezing point), geothermal heat pumps have excellent performance in any climate and weather. They can be used for virtually any size home and commercial buildings, or lot in any world region. How does it work? Basically, geothermal heating/cooling systems operate via sub-surface conductive heat transfer, using the natuÂrally renewable temperature of the earths crust as a heat source in the winter, and as a heat sink in the summer. Cooling Mode Operation In the cooling mode, the hot refrigerant (well over 100 degrees F) exiting the compressor is sent directly into the approximate 50 to 60 degree F range deep earth, which now absorbs and takes the heat away. The cooled refrigerant fluid is then circulated through the
