对青藏高原地区建筑太阳能热水供暖的几点看法

Some opinions on solar energy hot water heating for buildings in Qinghai-Tibetan Plateau

分析了青藏高原的气候和供暖热负荷的特点,认为青藏高原地区建筑供暖应充分利用太阳辐射热。对太阳能光热集热器的实时即热效率进行了分析,指出集热水温只有达到供暖温度要求,太阳能集热量才能作为太阳能贡献率的评价依据。对太阳能集热、蓄热、取热及辅助热源系统和室内供暖系统的参数优化组合进行了分析,提出了设计应用的方法。

By analysing characteristics of the local climate and heating load, thinks that solar radiation heat should be fully used in this region. Analyses the real time instant heat efficiency of solar heat collectors. Points out that only when the water temperature in heat collectors meets the requirement of heating can the solar heat collected be used as the basis for evaluating solar energy contribution rate. Discusses heat collecting, storing and taking of solar energy, and optimizing and combining of parameters of the auxiliary heat source system and indoor heating system. Puts forward the methods of design and application.
