西藏地区基于太阳能短期蓄热技术的清洁采暖研究分析

Research and Analysis of Clean Heating Based on Solar Short-term Heat Storage Technology in Tibet

西藏地区太阳能资源丰富且属于严寒地区,该地区非常适合推广使用太阳能供热采暖技术,既能解决藏区采暖问题,又是对国家清洁采暖政策的积极响应。本文以西藏某一典型太阳能短期蓄热采暖系统示范工程为例,监测并计算出系统的太阳辐照量、得热量、集热效率和太阳能保证率,结果表明该系统具有较高的集热效率和太阳能保证率,整个采暖季系统运行稳定,且满足了县城的采暖需求,环境和经济效益显著。

Tibet locates in severe cold area with rich solar energy resources,where is very suitable for promoting the utilization of solar heating technology,which can not only solve the heating problem,but also be a positive response to the national clean heating policy.This paper takes a typical solar energy demonstration project with short-term heat storage heating system in Tibet as an example to monitor and calculate the system's solar radiation,heat gain,heat collection efficiency and solar energy guarantee rate.The results show that the system has high heat collection efficiency and solar energy guarantee rate,runs stably in the whole heating season,and meets the heating needs of the county,with significant environmental and economic benefits.
