其次，该系统中没有氟利昂制冷工质，对环境没有污染。
What's more, there is no Freon refrigerant in the new system and no pollution effect.
科学家表示，如果淘汰氟利昂制冷剂能按照进度达成，到2000年时大气层应能开始自我修复。
If the CFC phaseout proceeds on schedule, the atmosphere should start repairing itself by the year 2000, say scientists.
介绍了表面增强型蒸发强化管，并对氟利昂制冷工质R22在该管外的沸腾换热进行了实验研究。
The experimental study on the performance of nucleate boiling of R22 outside the surface enhanced evaporation tubes was conducted by use of four two-sides enhanced tubes with different geometries.
各种废气，像二氧化碳、甲烷以及破坏臭氧层的氟利昂制冷剂，都可能捕捉阳光，提高地球上的温度。
Waste gases such as carbon dioxide, methane and the same CFCs that wreck the ozone layer all tend to trap sunlight and warm the earth.
因此，总的说来，直到Midgley发明氟利昂，没有一个气体，能被很好的用作制冷剂。
And so, by and large, until this freon was invented by Midgley, there wasn't a good gas that had the right properties to be used for a refrigerant.
未来的制冷剂将不会使用氟利昂。
以往的冷库中冷源有两种方式，一种是氟利昂机组单机对单个冷库直接制冷方式，一种是乙二醇间接制冷方式。
