摘　　要：分析空调室外机可能发生泄漏的部位及室外机附近可能出现的引火源。参照国内普通居民住宅的室外机安装间距,建立了空调室外机燃爆实验平台。对使用R290室外机的着火后持续燃烧进行了实验,结果表明在快速泄漏(320gR290在5～7min完全泄漏)的情况下,实验用的室外机被完全烧毁,但是未对同一高度的旁边的室外机造成损坏,也未引燃其上部或下部的室外机或造成损坏。对使用R290的空调室外机泄漏后的爆炸伤害范围进行了实验和数值模拟研究,结果表明R290在室外泄漏后发生爆炸对其旁边及上部的室外机基本没有损坏。The leak site and potential ignition source of air condi- tioning outdoor unit was analyzed. The air conditioning outdoor unit blasting experiment platform was established. The com- bustion and explosion experimentwas conducted. The burning experiment of the outdoor unit was conducted. The results showed that rapid leakage （320 g R290 was completely leak in 5-7 min）, the experimental outdoor unit was completely de- stroyed. But it did not damage the nearby outdoor unit, nor damage to the upper or the lower part of the outdoor unit. In addition, damage range of explosion wassimulated using FLACS. The results show that R290 explosion did not damage the next and the upper outdoor unit.
