摘　　要：为充分发挥太阳能与中深层无干扰地岩热技术的优势,建成太阳能与地热能耦合供热的测试平台。该测试平台由中深层无干扰地岩热系统、平板集热器系统、槽式集热器系统、真空管集热器系统构成。利用测试平台对太阳能与中深层无干扰地岩热耦合供热的应用案例进行测试。结果显示,采用太阳能与中深层无干扰地岩热耦合供热可以减少地岩热主机运行时长。太阳能系统平均供热量占比约为29.2%,太阳能系统平均集热效率达48%,耦合供热系统综合能效比为5.4,相比于中深层无干扰地岩热系统,耦合系统的综合能效提升17.4%,运行成本可降低约10.8%。To fully leverage the advantages of solar energy and deep unperturbed geothermal technology,a testing platform for the coupling heating of solar and geothermal energy has been established.This testing platform is composed of a deep unperturbed geothermal system,flat plate collector system,trough collector system,and evacuated tube collector system.The platform was used to test the application cases of solar and deep unperturbed geothermal energy coupling heating.The results show that using solar and deep unperturbed geothermal energy coupling heating can reduce the operating time of the geothermal host.The average heat supply proportion of the solar system is about 29.2%,the average heat collection efficiency of the solar system reaches 48%,and the comprehensive energy efficiency ratio of the coupling heating system is 5.4.Compared with the deep unperturbed geothermal system,the comprehensive energy efficiency of the coupling system is increased by 17.4%,and the operating cost can be reduced by about 10.8%.
