综合考虑设备安装及更新,能源价格上涨,集热器集热率和管道损失率变化,使用过程中的维修、清理、保温、运行,更换设备时的残值以及拆除费用等因素,建立太阳能热水系统在建筑全寿命期的经济性评价模型,并用案例对所建模型进行分析验证。结果表明,太阳能热水系统在建筑全寿命期内是经济可行的。 Taking into account factors such as equipment installation and renewal, energy price increase, heat collector heat collection rate and pipeline loss rate, maintenance, cleaning, heat preservation, operation, residual value at the time of equipment replacement, and dismantling expenses, etc., solar heat build Water system in the construction of the whole life cycle of the economic evaluation model, and the case analysis of the model validation. The results show that the solar hot water system is economically viable throughout the life of the building.
