空气式太阳能供暖系统在西藏地区的应用
Application of solar air heating system in Tibet area
摘要：
设计了一套空气式太阳能供暖及生活热水系统。阐述了其设计方案、运行特点、系统构成及控制原理。通过在西藏曲水县的实际应用，分析了其供暖系统的经济性和适用性。结果表明：空气式太阳能供暖系统在西藏地区运行稳定，室内温度可维持在18 ℃；与燃气锅炉和电加热锅炉相比，随着运行年限的增长，空气式太阳能供暖系统的节能效果越明显；该项目单个供暖季可节省257.36 t标准煤。
Abstract：
Designs a set of solar air heating and hot water system. Presents the design scheme, operation characteristics, system components and control principle in detail. Through its practical application in Tibet area, analyses the economic performance and applicability of solar heating system. The results indicate that the solar air heating system operates stably and the indoor temperature can be maintained at 18 ℃. Compared with gas-fired boilers and electric heating boilers, the energy saving effect of solar heating system is more obvious with the increase of the running years. The standard coal can be saved up to 257.36 tons in a single heating season.
