【摘要】 分析了西藏地区应用太阳能供暖的有利条件。结合工程实例,对太阳能热泵供暖系统与太阳能直接供暖系统(设有辅助电加热器)的供暖情况及经济性进行了对比分析。当室外温度变化时,太阳能热泵供暖系统及太阳能直接供暖系统均可满足供暖要求。太阳能热泵供暖系统的经济性优于太阳能直接供暖系统。更多还原

【Abstract】 The favorable conditions of applying solar energy for heat-supply in Tibet region are analyzed.With engineering examples,the heat-supply situation and the economy between the heat-supply system with solar heat pump and solar direct heat-supply system(adding auxiliary electric heater) are contrasted and analyzed.When outdoor temperature changes,the above-mentioned two systems can meet heat-supply requirement,but the economy of the former is better than that of the latter.更多还原
