摘要
在线热源理论的基础上,建立了地源热泵地埋管换热特性的数学模型。在夏季不同的运行模式下,对钻孔壁壁温进行了模拟,分析了温湿度独立控制的混合式地源热泵系统的运行效果,得出结论:混合式地源热泵系统能有效降低地埋管管壁温度,从而提升地源热泵的运行效率,为该地源热泵系统的设计和运行控制策略的制定提供参考。
A numerical model of heat transfer characteristics of buried tube heat exchanger is built,based on line heat source theory.Through the model,the borehole wall temperature is simulated with different operational modes in summer.The operation results of temperature and humidity independent control hybrid ground source heat pump system are analyzed.The hybrid ground source heat pump system can reduce the ground pipe wall temperature effectively,thereby enhancing the efficiency of ground source heat pump.The mentioned data can be the references for design and operation modes of the ground source heat pump system.
