摘要

基于线热源模型,研究地源热泵竖埋管换热器钻孔热阻、岩土导热系数及体积比热等热工参数的4种反演方法,基于实测数据进行反演计算。结果表明：只利用埋管进出口水温数据,采用寻优方法可得3个参数,但钻孔热阻及体积比热可能偏离物理实际。只利用水温、补充钻孔热阻或体积比热的反演方法得到的结果都有一定的不确定性。利用水温及壁温计算钻孔热阻、利用壁温反演岩土导热系数及体积比热,所得结果更符合物理实际。建议热响应测试同时记录水温及壁温,孔壁温度可在埋管上部、中部以及底部设置测点。

Abstract

Based on the line heat resource model, this paper studied four inverting methods for borehole thermal resistance, the soil thermal conductivity and volume specific heat of borehole heat exchanger of the geothermal heat pump system. Inverting computations were conducted based on thermal response test data. Results show that if only using the input and outlet water temperature data of the buried pipe to obtain above three parameters by some optimizing approach, two of them, that is borehole thermal resistance and volumetric specific heat, may deviate from the physical reality. There still exists uncertainty if borehole thermal resistance or volumetric specific heat is supplemented. If the water and borehole wall temperature are used to compute the borehole thermal resistance, and the borehole wall temperature is used to obtain thermal conductivity and volume specific heat in the inversion, result meets the reality better. It is recommended that the inlet and outlet water temperature and borehole wall temperature be recorded at the same time in thermal response test. Three measuring points should be set in the upper, middle and bottom of the buried pipe to record the temperature of the hole wall.
