摘要
结合对北方地区某公建地源热泵系统的工程设计,介绍岩土热物性测试的原理及测试方法;根据建筑逐时冷热负荷的动态模拟计算结果进行地下换热器的冷热平衡模拟与分析,并根据模拟结果对空调方案进行优化;详细分析钻孔间距、钻孔管径、钻孔长度及钻孔深度设计计算的原理。为今后地源热泵技术的应用提供指导和优化建议。
Through to a north public engineering design of ground source heat pump system, this paper introduces the principle of rock and soil thermal physical property testing and testing methods. According to the cold and hot load of the building by the dynamic simulation results of the underground heat exchanger, simulating and analysing of heat and cold, and the air conditioning scheme is optimized by the results of the simulation. It analyzes in detail the drilling hole spacing,hole diameter, length and drilling depth of the principle of design and calculation. It will provide guidance for the future and optimization of suggestions in the application of ground source heat pump technology.
