The Research On Performance Of Soil Source Heat Pump Air-conditioning System

With the progress of society and the development of economy, people ask more and more from the environment. indoor heat comfort has been required better and better, at the same time, environmental pollution has been a main focus for long time, the global warmer recent years even brings a high tide of environmental protection.As an equipment of improving indoor heat comfort, air conditioning changes outdoor environment as well as indoor environment. GSP, instead of traditional air conditioning system, high efficiency is not its only advantage, meanwhile, since the underground can be a huge heat storage without bad infection to the outdoor environment, which satisfies the request of sustainable development. However, the stored heat or cool will increasingly change when the heat and cool load is in unbalance, which will necessarily lead to the change of underground temperature field. This paper mainly studies the variation of underground temperature field when the GSHP runs long time. As a part of natural environment, the change of its parameters influences the entironment, this makes it necessary to study the underground heat saturation temperature field according to sustainable development. On the basis of linear heat source model, this paper analyzed the change of underground heat saturation temperature field on different parameters and distribution of underground pipes, the analysis of variation of incidence of underground pipe heat transfer offers foundation of setting reasonable space between underground pipes. then the author proposed to add assistant heat equipment to solve the variation of the underground temperature field, the economic performance of GSHP with assistant heat source equipment air-condition system is also analyzed in this paper, then the author picked out the problems of choosing assistant heat equipment nowadays and proposed to choose it in view of solving the variation of the underground temperature field.
