摘　　要：提出了一种新型的无水采暖系统方法,针对兰州市的采暖系统进行了实验研究,并对其热工性能进行了分析。在此基础上,得出系统运行期间的平均能效比COP为3.01,系统所能达到的最大能效比为3.81,室内温度最高可以达到24℃,能满足兰州市冬季供暖的要求与室内热舒适性要求。A new-type radiant floor heating system was proposed,and the heating system in Lanzhou was experimented and its thermal performance was analyzed. The results showed that the average COP was 3.01 and the maximum COP was 3.81 when the system was running, the maximum indoor temperature reached 24 ℃, and the new-type heating system met the requirements of winter heating and indoor thermal comfort in Lanzhou.
