Green machine : aircon that doesn 't warm the planet

绿色机器：不会让地球变暖的空调

Sales for clothes with their own personal aircon systems are soaring in japan , as seeks ever more ingenious ways of cooling down while saving energy as the nuclear crisis rumbles on .

这款附带个人空调系统的衣服在日本销量暴增，因为在核能危机未除之际，日本正在找寻巧妙的方式，既能节省能源又能降温。

In conventional vapour-compression systems used by aircon units , the refrigerant is compressed and condensed and then expanded and evaporated to cool the room .

空调设备使用的传统的蒸发压缩循环系统中，冷却剂被压缩冷凝后膨胀气化来给房间制冷。

That would be bad news for the planet , with aircon playing a significant role in the greenhouse-gas emissions produced by residential and commercial property roughly 10 per cent of the world 's total emissions , says graeme maidment at london south bank university .

但那对地球来说是个坏消息，因为居住和商业用房空调排放的温室气体比例可观-大约占全球总量的百分之十，来自伦敦南岸大学的格瑞米梅德门特说。
