A geothermal heat pump (GSHP or called ground source heat pump including groundwater, soil or surface water) is a central heating and/or cooling system that transfers heat to or from the ground.
★ GSHP is utilizing renewable energy, as subsurface is a enormous solar collector and absorbing 47% solar energy which is over 500 times the amount of human’s energy utilization.
★ Economic, efficient and energy saving technology
★ Remarkable environmental benefits
★ GSHP serves several purposes including heating, cooling and domestic hot water.
GSHP saves over two-thirds electrical energy than electric boiler does and saves more than half energy than fuel boiler does, comparing to boilers (electricity and fuel).
Heat source temperature of GSHP maintains a nearly constant temperature between 10 and 25 °C. The system reaches fairly high coefficient of performance (CoP), 3.5 to 4.4 and the operational cost is 50-60% of the one of conventional HVAC.
Geothermal/groundwater heat pump HVAC are widely used in hotel, office building, shopping mall, apartment, stadium, barrack, airport, dwelling house, school, hospital and plant etc. It is currently one of the most economic and efficient energy-saving HVAC systems and applicable for cold/hot regions with different climates.
Water is used as carrier utilizing a nearly constant temperature beneath of Earth's surface in Geothermal/groundwater heat pump system. GSHP is a environmental friendly, energy-saving and Zero discharging system with all-year utilization. Generally users can obtain over 4kw of heat or cooling capacity while the energy consumption of GSHP is 1kw. The main features are:
• Vertical closed loop
• Horizontal closed loop
• Pond closed loop
