地下水渗流对土壤耦合热泵换热器传热的影响

Heat transfer analysis of underground heat exchangers under coupled thermal conduction and groundwater advection

针对国内外关于土壤耦合热泵的传热模型及其计算方法,未考虑地下水渗流的影响的问题,应用地下水渗流理论和传热学理论,建立了考虑热传导和地下水渗流共同作用的热渗耦合传热模型,分析了地下水渗流对其传热模型的影响,这为土壤耦合热泵换热器的传热计算和分析提供理论支持。

The influence of groundwater seepage is not considered in heat transfer model and calculation method of ground-coupled heat pump.In view of this problem,with underground water seepage theory and heat transfer theory the transfer model of coupled thermal conduction and groundwater advection is established.The effect of Groundwater seepage on transfer model is analyzed.These studies provide theoretical support for calculation and analysis of heat exchanger of ground-coupled heat pump.
