INNOVATIVE SYSTEM SDH-C FOR SUPPLY BUILDING ENERGY BASED ON RENEWABLE ENERGY SOURCES

Energy supply is a prerequisite for economic and social development. Energy is not moved by the most sophisticated mechanisms, nor the most intelligent computer, and it is not possible construction and operation of buildings. One of the basic conditions for sustainable development is sustainable energy supply that also has to be reliable and to meet the quantitative and qualitative requirements of the user system. Sustainable energy supply based on fossil fuels is limited to a period in the history of the development of human civilization is only a very short episode, because their stocks are finite and are diminishing at a rapid pace. Historically a relatively short time mankind will be confronted with a serious problem to replace fossil fuels, of which currently covers a crucial part of its energy needs. In the context of energy supply on "Sustainability" can talk only about the supply from renewable sources (RES), which represent different forms of solar energy. Indeed the sun will radiate to the Earth in an hour more power than its entire annual needs even billions of years. Energy emitted by the Earth is very sparse and now even the most sophisticated equipment it can be transformed into commercial forms as efficiently as possible to those obtained from fossil sources. Nevertheless, they may be relatively effective substitute mainly on the supply of building heating/cooling, because to create thermal comfort is necessary to maintain a relatively small difference between the interior and exterior temperature. The heat supply systems of buildings right combination of biomass and solar energy can be in many cases a suitable substitute for fossil fuels. Solar radiation is the cleanest renewable energy source, it is therefore desirable that its share was the greatest. In this crucially affect the technical excellence as well as the type and size of solar heat reservoir. The transition from short-term to seasonal accumulation allows to increase the degree of solar coverage in the supply of heat from the current 15-30 % theoretically up to 100 real to 40-70 %. Due to the high investment intensity, this should not be part of the transition from the smaller decentralized systems performance to centralized systems, which are known as SDH (Solar District Heating). Article deals with upgrade options the standard SDH system in order to increase its competitiveness. As a major innovation measures are considered: the replacement of fossil fuels with biofuels, which is used for combined heat and power and integration of the heat pump system structure in order to increase the capacity of the seasonal heat accumulator. With proper concept of collaboration with the container lets you use the cooling capacity of the heat pump. SDH system will change to the system SDH/C (Solar District Heating/Cooling), which as a valuable by-product also produces electricity.
