Did you know that in addition to geothermal systems, installed in certain parts of the world, dedicated to the exploitation of volcanic or geological anomalies there are more children are classified as "low enthalpy" relating to the use of subsoil as a reservoir to extract heat from the heat during the winter season and to whom to hand over the summer. Geothermal systems take advantage of domestic natural energy, clean and renewable, in the land captured by sensors buried, and multiplying with a heat pump for heating, for production hot water, and in summer for cooling a single macchina.Il system is applicable in any type of soil in any region of Italy, at any geographical location: sea, mountain, plain, hill, near the lake, city, country.
Operation:
The system works by using a simple circuit drawing heat into the ground and a heat pump. The circuit of heat transfer between building and ground is by means of an exchanger immersed in the soil. This exchanger consists of a tube forward and one return, placed in a vertical hole with a length generally between 70 and 120 m, drilled in the ground surrounding the house. The implementation of the trading system involves the insertion of polyethylene tubes connected with a U-fitting at their lower end. Inside the tubes, which form a closed circuit, is circulated a heat transfer fluid which is the physical medium through which heat exchange takes place. During a cycle of winter heating the liquid down to low temperatures (around zero) in one of two tubes, heated by the heat to go up in the soil. This simple collection system is called probe geotermica.Il only extract heat from the ground is enough to heat a building and the liquid must then be conveyed to a heat pump, which raises its temperature to be able to eventually transfer to the terminals: heaters, hot plates or panels radianti.Una heat pump operates similarly to a domestic refrigerator. In fact, as it removes heat from inside the refrigerator to reject the premise where the equipment is located, so the heat pump removes heat from the geothermal probe (after the latter took it from the ground) and provides the heating circuit. Heat pumps are recognized to be one of the most promising and economically viable technologies to reduce harmful emissions, including greenhouse gases (eg. CO2). The building has geothermal and appropriate terminals is thereby heated with free energy from the ground. The only cost to the user 's electricity needed to operate the heat pump. With direct experience in this technology is now well established and yields of the plants are growing. E 'was found that this solution results in a substantial savings over traditional systems in seasonal boiler and also cancels the emissions of polluting gases into the atmosphere. The installation of the geothermal probe is simple and does not require large areas and involves a visual impact and size zero in esterno.Misure and studies of real plants have shown that the heat taken from the subsoil is regenerated quickly and completely by geothermal energy, even after many years of operation. Sampling of geothermal energy is then a levy environmentally favorable energy sources. The almost constant temperature of soil throughout the year allow the heat pump to achieve high returns even in winter, electricity for less than a quarter of the geothermal energy that provides the heating system. This, in addition to lower operating costs, means using less energy resources more valuable and renewable energy. The efficiency of these devices is very high: you can turn 1 kW of electricity at about 4.5 kW of thermal energy. A geothermal system will pay for itself within a few years and, with a minimum expenditure in terms of electricity, it is possible to have heating, cooling and hot water all year. The advantage of geothermal systems is that they allow, through a single system, to provide housing for both heating and cooling environments. This represents a significant reduction not only on the costs of winter space heating but also cooling in the summer. Through cooling is also possible to reinstate the heat removed from the soil during the winter months, and then restore the conditions optimal for subsequent years of operation.
