摘　　要：为了进一步提升北方地区土壤源热泵全季节运行效果,设计了太阳能与土壤源热泵耦合系统,以温度控制启停,实现太阳能储热水箱适时换热补热;并设置监测井,通过热响应试验测量全周期土壤温度,数据结果表明,所设计系统可有效解决寒冷地区土壤源热泵系统浅层土壤温度逐年下降的问题,且太阳能集热器的集热面积与供暖建筑面积之比为1∶14时浅层土壤温度可达到热平衡,实现供暖供冷系统稳定可靠、能效高、运行费用低的效果,对于土壤源热泵在北方寒冷地区的推广应用具有参考意义。To further improve the full-season operation effect of the earth-source heat pump in Northern China, this paper designs a coupling system of solar energy and earth-source heat pump that starts and stops with temperature control to realize the timely heat exchange and concurrent heating of the solar water storage tank. Setting monitoring wells, the full-cycle soil temperature is measured by the heat response test. The test data showed that the designed system can effectively solve the problem that the shallow soil temperature of the soil source heat pump system in cold regions decreases annually, and the shallow soil temperature reaches heat balance when the solar collector collecting area and heating floor area ratio is 1∶14, realizing the stable and reliable operation, high energy efficient, and low operation cost of the heating and cooling system. This paper is of reference significance for the promotion and application of the earth-source heat pump in cold regions in Northern China.
