基于冷热平衡的复合式土壤源热泵系统设计研究

Research on the Design of Composite soil source heat pump system based on cold and heat balance

地源热泵以其独有的能效优势、低碳排放、低品位能源利用等特点,受到国内外学者的青睐。近年来,因冷热平衡问题,衍生出了复合式地源热泵技术。以具体工程实例,从岩土热响应实验、全年动态冷热负荷、热平衡分析、辅助热平衡措施、运行策略等方面,探讨复合式土壤源热泵系统设计。

Ground source heat pump technology has been widely concerned by domestic and foreign scholars,with its unique energy efficiency,low carbon emissions and low grade energy utilization.In recent years,the composite ground source heat pump technology has been derived due to the hot and cold balance problem of soil.In this paper,the design of a composite soil source heat pump system has been investigated based on the real project.The research contents include geotechnical thermal response experiment,annual dynamic cold and heat load,heat balance analysis,auxiliary heat balance measures,operation strategy,etc.
