13 GEOTHERMAL HEAT PUMPS The geothermal heat pumps provide low cost energy and a high level of comfort because they rely on the natural thermal energy from the Earth. These systems require a small amount of electricity for heating or cooling in order to achieve a small price maintenance for the living space. These systems are used for single or multifamily homes, hotels and motels, shops, shopping centers, gas stations, office buildings, hospitals, banks and schools. Operation Heat pumps have an underground piping system that circulates a fluid (usually a mixture of water and antifreeze). During winter, the fluid captures the soil temperature, and then transports it to the building heat pumps which concetrate this temperature and distributes it on to residential areas to warm them. In summer, the process is reversed, the heat inside the building is absorbed by the heat pump and then dispersed into the ground. This excess heat can be used for domestic water heating. Depth at which pipes are inserted (180 cm) provides a constant temperature between 8 and 12 C throughout the year. 13

14 The efficiency Geothermal systems have the lowest operating costs of the existing residential and commercial air conditioning field. Unlike an electric air conditioning system, costs are reduced by 70%, 50% compared to the costs implied by the air source heat pumps. For the systems that use fossil fuels, costs are reduced by 70% and the cooling process for the buildings saves 90%. The coefficient of performance of geothermal heat pumps is 3.5 to 6, which means that every unit of electricity fed into the system gets 3.5 to 6 units of energy in the building, as 3.5 to 4 units energy from Earth, for Free. The advantages of the geothermal systems The savings made compared to any classical system used Protection and natural resources economy Environmental protection No danger of explosion Noise free and do not require expensive maintenance High reliability Purchase prices are around 3-5 Euro / W Depreciation expenses in 5-7 years SUN COLLECTORS The operating principle of such a device is represented by capturing the solar power into a fluid which is then used to heat water. The main advantages are: direct conversion of solar thermal energy high solar energy conversion efficiency, up to 60% purchase price is about EURO/m2. 14
