摘　　要：暖通空调行业作为实现“双碳”目标的重要领域,其低碳发展对实现目标起着重要的作用。以夏热冬冷地区上海市某工程为例,对其进行设计日逐时冷热负荷,不同负荷区间的累计冷热负荷分布进行计算,得出不同负荷区间的运行时间、累计冷热负荷值以及对应的室外干湿球温度平均值。空调系统部分负荷时间占比较大,基于制冷时候优先开启冷水机组,制热时优先开启风冷热泵机组的运行策略,通过4种空调冷热源方案的比较,从初投资、运行能耗、碳排放角度论证了冷水机组+热水锅炉+风冷热泵组合形式具有一定的推广性,以期为其他工程空调冷热源方案的选择提供设计参考。HVAC industry is an important area to achieve the goal of carbon neutrality and carbon peak,and its low-carbon development plays an important role in achieving the goal.Take a project in Shanghai with hot summer and cold winter area as an example,calculate the cooling and heating load hourly on the design day,and calculate the cumulative cooling and heating load distribution of different load intervals,the operating time,cumulative cooling and heating load values of different load intervals and the corresponding average outdoor dry and wet bulb temperature are obtained.The part load time of the air-conditioning system is relatively large,based on the operating strategy of turning on the chiller when cooling,and turning on the air-cooled heat pump when heating,through the comparison of four air-conditioning cold and heat source schemes,it is demonstrated that the combination of chiller+hot water boiler+air-cooled heat pump has a certain degree of popularization from the perspective of initial investment,operating energy consumption,and carbon emissions,in order to provide design reference for the selection of air-conditioning cold and heat source solutions for other projects.
