Energy Saving Geothermal Water Source Heat Pump , Cooling Heating And Sanitary Hot Water 1. What is geothermal source heat pump? A geothermal heat pump or ground source heat pump (GSHP) is a central heatingand/or cooling system that transfers heat to or from the ground.It uses the earth as a heat source (in the winter) or a heat sink(in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solare heatingto form a geosolarsystem with even greater efficiency. They are also known by other names, including geoexchange, earth-coupled, earth energy systems.. 2. Geothermal source heat pump working principle (1) Depending on latitude, the temperature beneath the upper 6 metres (20 ft) of Earth's surface maintains a nearly constant temperature between 10 and 16 C (50 and 60 F),if the temperature is undisturbed by the presence of a heat pump. Like a refrigerator or air conditioner, these systems use a heat pumpto force the transfer of heat from the ground. Heat pumps can transfer heat from a cool space to a warm space, against the natural direction of flow, or they can enhance the natural flow of heat from a warm area to a cool one. (2) The core of the heat pump is a loop of refrigerant pumped through a vapor compression refrigerationcycle that moves heat. A ground source heat pump exchanges heat with the ground. This is much more energy-efficient because underground temperatures are more stable than air temperatures through the year. Seasonal variations drop off with depth and disappear below 7 metres (23 ft)to 12 metres (39 ft)due to thermal inertia. Like a cave,the shallow ground temperature is warmer than the air above during the winter and cooler than the air in the summer. (3) A ground source heat pump extracts ground heat in the winter (for heating) and transfers heat back into the ground in the summer (for cooling). Some systems are designed to operate in one mode only, heating or cooling, depending on climate. (4) Geothermal pump systems reach fairly high coefficient performanceon the coldest of winter nights, compared to 1.752.5 for air-source heat pumps on cool days.Ground source heat pumps (GSHPs) are among the most energy efficient technologies for providing HVAC and water heating. 3.
