地埋管换热器换热效果良好与否关系着整个系统运行效率。本文提出了地埋管换热器换热效果评价方法。该方法以地埋管传热热阻为切入点,针对影响地埋管传热热阻的3个因素:地埋管施工质量、地埋管设计参数及地埋管累计换热量,明确地埋管换热器的评价应排除第3个因素,而着眼于前2个因素,提出了地埋管出水温度与最优热阻评价2种评估方法。 Ground heat exchanger heat exchanger effect is good or not related to the entire system operating efficiency. This paper presents a ground tube heat exchanger heat transfer evaluation method. The method takes heat transfer resistance of buried pipe as the starting point. According to three factors that affect the heat transfer resistance of buried pipe, such as the construction quality of buried pipe, the design parameters of buried pipe and the cumulative heat exchange of buried pipe, The evaluation of the buried heat exchanger should exclude the third factor, but the two factors which are the first two factors are put forward. Two evaluation methods are proposed for the evaluation of the outlet water temperature and the optimal thermal resistance of the buried pipe.
