摘要
《蒙特利尔议定书》签署20周年之际,2007年9月又召开了缔约方大会。会上,各国代表努力磋商让全世界有好消息,那就是进一步加速淘汰臭氧层消耗物质(ODSs),包括氢氯氟烃(HCFCs),其中最广泛使用的制冷剂(又称冷媒)HCFC-22成了关注的焦点。本文回顾了蒙特利尔协议的最新规定;现今人们日益意识到气候变化的不良后果,那些通常被认为可接受的替代冷媒由于其可持续性的问题而受到质疑。本文在近期科研的基础上,以综合环境影响作为可持续发展的基本考虑,探讨了建筑空调用冷媒的各种选择方法。
The September 2007 Montreal Protocol meeting marks the 20th anniversary and the Parties negotiated very hard to come up with a great news for the whole world, that is to accelerate the phase out of ozone- depleting substances （ODSs）, including hydrochlorofluorocarbons （HCFCs）, of which the most widely used refrigerant HCFC - 22 was the focal point. This paper reviews the new directive from Montreal Protocol. While the consequence of Climate Change is more aware of today, those commonly acceptable alternative refrigerants become questionable because of the sustainabihty concerns. With reference to the recent scientific findings, various methodologies in selection of refrigerant for air - conditioning use in the building industry are discussed in this paper through integrated environmental approach.
