寒冷地区被动式建筑能源系统形式分析

Energy Systems of Passive Building in Cold Area

通过对我国被动式建筑示范项目的信息收集,总结了当前我国被动式建筑发展的特点,指出寒冷地区是我国目前大力发展被动式建筑的重点区域。通过对大量国内外类似气候条件下相同负荷需求特点的被动式建筑实际案例及其能源系统形式的收集整理,分析寒冷地区被动式建筑能源系统形式需求倾向及特点,得出我国现阶段寒冷地区的被动式建筑项目中太阳能生活热水和热泵技术仍然是最具吸引力的能源系统形式,同时随着PV产品经济性条件的改善,PV在寒冷地区也具有较大应用潜力。

Based on the information collection and classification of a large number of both domesticand foreign existing passive building demonstrations together with the passive energy systems, this paperconducts a clear summarization and a deep analysis on existing energy systems, based on different climaticzones and different types of buildings. For existing passive building projects in cold regions in China, thesolar domestic hot water and heat pump technology are still the most attractive technologies, following theimprovement of economy） PV in cold regions also has greater potential applications in future.
