浙江省《民用建筑碳排放计算标准》中暖通空调运行碳排放计算方法

Calculation method of operational carbon emission for HVAC in Carbon emission calculation standard for civil buildings of Zhejiang Province

介绍了该标准中民用建筑运行碳排放的计算边界,冷热源、输配系统及风系统运行碳排放的计算方法。该标准对民用建筑运行碳排放的计算边界作了扩展与延伸,覆盖了全寿命周期的全边界;定义了建筑运行名义工况,统一了民用建筑碳排放计算时标准的建筑使用模式及建筑设备运行模式;补充了暖通空调各系统的详细算法,给出了空调冷热源、输配系统、末端空气处理设备及通风风机的运行能耗与碳排放量计算公式,提高了在浙江省范围内建筑碳排放计算的可操作性。

This paper presents the calculation boundary of operational carbon emission from civil buildings,and the calculation method of operational carbon emission from cold and heat sources,transmission and distribution systems and air systems in this standard.This standard expands and extends the calculation boundary of carbon emissions from civil buildings,and covers the whole boundary of the whole life cycle.This standard defines the nominal operating conditions of buildings,and unifies the standard building use mode and equipment operation mode in the carbon emission calculation of civil buildings.The detailed algorithms of HVAC systems are supplemented,and the calculation formulas of operating energy consumption and carbon emissions of air conditioning cold and heat sources,transmission and distribution systems,terminal air treatment equipment and ventilation fans are given.It improves the operability of carbon emission calculation of buildings in Zhejiang Province.
