Study On Low Temperature Hot Water Floor Radiation Heating System With Auxiliary Heating Solar Energy

Currently, energy crisis has become an important dilemma which all the countries in the word have to face. Most countries are all trying their hard to improve the energy structure, so as to break out of their dependence on the fossil energy. The America, West Europe, Japan, Israel and some other countries are all taking great pains to develop their renewable energy industry, and have formed technology advantage and industry chain. Recently,though our country has begun to develop the renewable energy industry, it is still at an initial stage. A great mass of coal, oil and other fossil energy are consumed in the traditional industrial and civilian field every year. Not only is the energy wasted, also the environment is polluted. Take the urban central heating for an example, A great mass of coal and oil are consumed every year, which pollutes the air and seriously violates the policy of energy conservation and emission reduction. Thus aim to the most universal heating system of our country in the present, study on low temperature hot water floor radiation heating system with auxiliary heating solar energy is put forward. The floor heating system is a new type heating system in the present, and is populated by its scientific, energy saving property and thermal comfort. This paper mainly does some research on following aspects:First, aim to Zhenzhou's location and according to relative theory, this paper will establish the solar radiation model of Zhengzhou region and determine the optimum tilted angle of solar collector in Zhengzhou region.Second, Compared with the popular type of solar collector recently, Choose the optimum solar collector type which will suit Zhengzhou region.Third, calculate the thermal load of heating room, and aim to the specific environment of heating room, determine the optimum piping mode and pipe pitch of ground coiled pipe, the thickness of different layers of ground and the volume of heat storage water tank. Apply the present value of synthetic energy price and compare with the four types of auxiliary heat source, choose the best type of auxiliary heat source.Fourth, test the low temperature hot water floor radiation heating system. Compared with the radiator heating system and floor heating system, give an quantitative evaluation about the energy saving property of floor heating system in exergy analysis terms.Floor heating technology has numerous benefits, such as energy saving, scientific, comfortable, and so on. In addition, the floor heating technology, which combined with solar technology and biomass technology, will be more helpful for the extension of floor heating system. It will solve the problem of peasants'energy consuming, improve the peasants'living condition and improve their life quality. The solar and floor heating system will make an expansive development prospect.
