Solar Ground Source Heat Pump Integrated Heating System Application Research

With the rapid growth in the number of architecture and increasing demand in human comfort to the interior environment, the architecture energy consumption is rising rapidly. Combined with the national conditions, the total amount of building energy consumption has followed industrial energy consumption and traffic energy consumption, ranked third. In this context, the calls for the energy conservation and emissions reduction is higher and the demand to the use of renewable energy sources is more and more urgent, and all the energy saving technology arises at the historic moment.To solve the problem, the solar heating technology and ground source heat pump heating technology are analyzed and studied in this project, and pointed out the advantages and disadvantages of the two technologies respectively. At the same time, according to the present situation of cold load in summer less than heat load in winter, and it resulting the phenomenon of cold quantity the soil in the summer far less than of taking heat. At last, the technology of heating in solar energy-ground source heat pump is advocated. Thus it can make up the disadvantages in the two technologies, but also to the purpose of energy conservation and emission reduction.This paper first analyses the technology of solar energy-the ground source heat pump heating system integrated application, and points out the feasibility and necessity. Then Changchun area as an example, the technology of economic analysis, a building model, draws up the three kinds of heating schemes (namely the traditional boiler heating, ground source heat pump heating, solar-independent ground source heat pump integrated heating) and calculate initial investment and operation cost, after that comparing the three schemes. Finally, further validation solar-ground source heat pump integrated heating energy conservation based on the results of the calculation of the building model, and points out the application and development of it has a considerable foreground.
