摘　　要：结合某工程案例,对呼吸幕墙通风系统进行设计,并利用HDY-SMAD V4.0软件对该工程采用的水环式变频多联式空调(热泵)机组利用冬季内区余热为外区供暖进行模拟和分析。结果表明,该呼吸幕墙办公建筑标准层在冬季只有约60 h需要采用辅助热源进行供暖,大部分时间回收建筑内区的热量即可满足空调使用要求,每年可节约天然气用量约1 033 m~3,减少碳排放约1 818.1 kg。Combined with an engineering case,the breathing curtain wall ventilation system is designed,and the method of water loop frequency-conversion multi-connected air-conditioning(heat pump) units recovering the waste heat in the inner zones for heating the outer zones in winter is simulated and analyzed by HDY-SMAD V4.0 software.The results show that the standard floor of the breathing curtain wall office building only needs auxiliary heat source for about 60 hours in winter,and the heat in its inner zones can be recovered to meet the requirements of air-conditioning at most time,with about 1 033 m~3 of natural gas saved and 1 818.1 kg of carbon emissions reduced annually.
