中文摘要： 北方地区住宅建筑普遍没有设置新风系统，人们无规则的开窗行为普遍存在，室内空气品质改善与建筑节能的矛盾是亟待解决的问题。本研究提出将相变储能系统、新型双效光伏电热（PVT）装置与建筑有机结合，构建一种光伏电热-相变储能新风与热水集成系统（PVT-AW-PCES集成系统），冬季PVT装置加热新风并联合室内供热系统作为备用热源，相变储能系统蓄热提供夜间新风，热泵热水器回收排风热能；夏季PVT装置联合热泵热水器供应生活热水。为了解系统能量转化与传递规律、建筑需求与气候调节适应性，利用理论分析、模拟计算与实验测试相结合的方法，开展系统与建筑的能量协同转化机理、关键过程、系统优化与运行效果等研究，得到PVT-AW-PCES集成系统在不同季节工况的动态模型描述及分析方法，实验测试基础数据及运行规律，从而实现冬季新风与全年生活热水的节能管理，为北方地区住宅室内空气品质改善和建筑节能提供一种新办法。

英文摘要： Fresh air system is generally not designed in the northern residential buildings and the window-opening behavior without rules is widespread among residents. Consequently, indoor air quality improvement and its contradiction with building energy conservation is a problem to be solved urgently. Through organic combination of phase change energy storage system, a new double functional photovoltaic/thermal device (PVT) and building, we propose a kind of Photovoltaic/thermal fresh air and hot water incorporated system with phase change energy storage (PVT-AW-PCES) as well as regulating function according to outside climate change. In winter, PVT device produce heated fresh air with indoor heating system as backup heat source; phase change energy storage system provides fresh air at night; exhaust air heat is recovered by air source heat pump. In summer, PVT device supply domestic hot water together with air source heat pump as auxiliary. To understand energy conversion and transfer law of the system, building requirements and adaptability to climate regulation, we proposes to study the energy cooperative transformation mechanism of the system and building, key process, system optimization and its running effect using theoretical analysis, numerical simulation and experimental testing method. Finally, research resul
