Research on calculation methods of annual energy saving using heat recovery devices in nearly zero energy
摘要：
基于GB/T 51350—2019《近零能耗建筑技术标准》，提出了近零能耗居住建筑中采用新风热回收装置全年节能量计算方法，并对全国主要气候区5个代表城市近零能耗居住建筑中采用热回收装置的全年节能量进行了计算分析，给出了各代表城市近零能耗居住建筑中采用热回收装置全年节能量范围，并分别给出了过渡季采用机械通风和自然通风时设置旁通功能对热回收装置全年节能量的提高程度。
Abstract：
Based on GB/T 51350-2019 Technical standard for nearly zero energy buildings, puts forward a calculation method of annual energy saving of nearly zero energy residential buildings with outdoor air heat recovery devices. Calculates and analyses the annual energy saving of nearly zero energy residential buildings with heat recovery devices in five representative cities in the main climatic regions of China. Lists the annual energy saving range of heat recovery devices used in nearly zero energy residential buildings in representative cities. Gives the improvement degree of annual energy saving of heat recovery devices by setting bypass function when mechanical ventilation and natural ventilation are used in transition season, respectively.
Keywords:heat recovery, nearly zero energy building, residential building, amount of energy saving, climatic region
