摘　　要：我国太阳能辐射资源丰富,大力开发太阳能资源,对改变国家能源结构,优化能源配置,提高能源综合利用率具有重要意义。在分析太阳能与常规供热方式联合供热的基础上,提出一种新型的槽式太阳能与电锅炉互补采暖系统,白天光照条件好的情况下,利用槽式太阳能将集热管内部的水加热到额定温度,通过水水换热器加热供暖系统;光照条件不好的条件下,槽式太阳能与电锅炉共同提供热源;晚上或白天无光照条件下,利用电锅炉为供暖系统提供热源,从而达到全天24 h供热。It is of great significance to develop solar energy resources in China, which changes the national energy structure,optimizes the energy allocation, and improves the comprehensive utilization rate of energy. A new kind of parabolic troughsolar collecting heat system is put forward on the basis of analyzing the combined solar energy and traditional energy. Duringthe daytime with enough light intensity, cold-water is pumped into the parabolic trough solar concentrator heated to the ratedtemperature and provide heat for the collecting heat system. During the daytime with light deficiency, parabolic trough andelectrical boiler works together to provide heat for the collecting heat system. During the night time or the daytime withoutlight, electrical boiler is utilized to provide heat for the collecting heat system so as to achieve 24-hour-heating.
