What's more, there is no Freon refrigerant in the new system and no pollution effect.
其次，该系统中没有氟利昂制冷工质，对环境没有污染。
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.
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。
Freon will not be used as refrigerant in the future.
未来的制冷剂将不会使用氟利昂。
