Energy Efficiency Analysis And Evaluation Of Ground Source Heat Pump In Operation Management In Hot Summer And Cold Winter Area

The development and promotion of renewable energy in the areas of civil construction and public building heating and cooling is already the most important part of China's energy planning encouragement and support.Among them,the geothermal heat pump academic research on the rational use of geothermal energy has promoted renewable energy sources.With the rapid development of building applications,the ground source heat pump air conditioning system has also opened up new ways to solve the winter heating problem in hot summer and cold winter regions.As for the actual conditions of the ground-source heat pump,where the hot summer and cold winter areas are increasingly increasing,the testing and summary analysis of the subject are still lacking.This article analyzes seven key evaluation indicators for 48 ground-source heat pump demonstration projects in hot summer and cold winter regions,including: indoor and outdoor actual effects,unit performance,system energy efficiency,pump and unit energy consumption,energy conservation,environmental protection,and Economic benefits.Through the actual measurement of the unit import and export water temperature,flow,unit,pump and system power consumption,one by one to demonstrate the impact of system energy efficiency factors,and to improve the unit and system energy efficiency,improve economic efficiency for example refinement of the design and management improvements Suggest.The applicability of the five types of ground source heat pump in six typical hot summer and cold winter provinces is summarized.This research data can provide guiding application value for the design and optimization of the ground source heat pump project in the use of renewable energy buildings.The evaluation results of the ground source heat pump project can be used as reference in the actual project.
