Evaluation and Analysis of Comprehensive Benefit of Ground Source Heat Pump in Cold Area

Abstract

Abstract In recent years, with the vigorous implementation of the national measures to promote green building energy conservation, a series of regulations and norms concerning building energy conservation policies have been published. Solar energy, heat pump and other clean energy has also been widely used. According to summarize the influencing factors of the operation of the ground source heat pump system, the evaluation method of comprehensive benefit of the ground source heat pump system is proposed, and the evaluation system of various types of heat pump system is integrated through using the unified dimension. Analytic hierarchy process is used to study the evaluation method of the ground source heat pump. A scientific, rational and practical comprehensive benefit evaluation system of ground source heat pump is constructed. At the same time, the evaluation standard of 15 evaluation indexes and the grading standard of comprehensive benefit evaluation are established. The typical soil source heat pump project is selected for the evaluation and its comprehensive evaluation benefit grade is two-level. Based on the evaluation results, we can effectively analyze the areas that need to be optimized and improved, so as to improve the comprehensive benefit.
