The Energy-saving Analysis Of Ground Source Heat Pump System And Feasible Appraisal System Construction

The energy consumption in air conditioning is the major part of building energy consumption, and the extensive use of air conditioning technology makes a substantial increase in the building energy consumption, therefore, the air conditioning energy-saving technologies is an important means to reduce the building energy consumption. In this context, Ground Source Heat Pump air conditioning system which benefit energy-saving and environmental protection came into being, and are widely used, meanwhile this technology also caused many problems in actual project. The thesis introduced the classification, working principle and design points of Ground Source Heat Pump System, detailed analyzed the heat transfer performance of the vertical ground heat exchange system., and described the general formula in the acual heat exchanger engineering.The thesis used the level of well-known Analytic hierarchy process-Fuzzy comprehensive method which well-known in systems engineering to construct the feasibility evaluationthe system of the Ground Source Heat Pump system, established a ground source heat pump system feasibility evaluation index system, and through the example of a typical project feasibility assessment to verify the credibility of the evaluation index system.In through of the example of a Ground Source Heat Pump demonstration project in Minhang District, Shanghai, the thesis comprehensive analysis the vertical ground source heat pump system afeasibility evaluation and obtain a quantitative analysis. This thesis proposed the economy and energy efficiency indicators of ground source heat pump and analysis of the evaluation principles, combined with vertical ground source heat specific projects examples, and Concretely analysisd the efficiency and energy conservation of ground source heat pump system..
