Integrated Performance Evaluation Of Buried Ground Source Heat Pump System

As the dominant forms of ground-source heat pump air conditioning technology, ground has a very good ground source heat pump system of energy-saving and environmental benefits, and to some extent avoided, such as groundwater source heat pump system negative impact on groundwater resources, has been widely studied and applied in our country. But to buried tube to source hot pump system early investment is high, system more huge, on venues of requirements also high, for actual of engineering for, select to buried tube to source hot pump system what savings how many general energy, achieved how many carbon dioxide emission reduction volume, problem are is needs analysis of, if blind used, not only up not to ideal of run effect, even not to normal run, on energy and resources are is serious of waste. Therefore, it is necessary to consolidate the system of energy-saving, environmental protection, economic and technical benefits, establish a relatively complete set of ground source heat pump system performance evaluation system. This is the background to this study and starting point.This article from a ground source heat pump operating principle, characteristics and practical application of the system start, summarized the main factors of ground source heat pump system and establishment of integrated evaluation index hierarchy structure, through analytical hierarchy process and concluded that the weighting of the index. And theory based on multiple linear regression analysis using SPSS software, some known with its corresponding second-level indicators between the prediction formula. Through a combination of AHP method and multivariate linear regression analysis, and finally established the target layer and secondary indicators between the prediction formula. Through the secondary indicators actual values for each factor to predict the target layer of ground source heat pump system integrated evaluation index. This article by summarizing the relevant normative standards of ground source heat pump system, the establishment of a ground source heat pump system performance evaluation score system, and eventually received by target of prediction formula of ground source heat pump system of comprehensive performance evaluation index scores.Through the evaluation of specific and practical projects, this article concluded that ground source heat pump system in terms of energy-saving effect is remarkable. Economy, investment, particularly larger drilling costs at the beginning. Environmental protection can effectively increase the amount of greenhouse gas emissions, dust emissions, reducing air pollution. But on thermal stability of groundwater will have some negative effects.Concludes this research on the subject of regional reference application of ground source heat pump technology, can lead to healthy development of the ground source heat pump, prom ote the local conditions and rational use of renewable energy. While actual engineering design of ground source heat pump system also has the certain referencevalue.
