Then, that cold water flows into the refrigeration or air conditioning system to help chill refrigerant liquid.

然后，冷水流入制冷或空调系统，帮助冷却制冷剂液体。

The electricity is often produced by burning fossil fuels, and the refrigerant gases also exacerbate climate change.

而冷藏所需的电通常是由燃烧的燃料生产的，且制冷气体也会进一步加剧气候。

In addition to that, ammonia is also used as a refrigerant gas, as well as in the manufacture of plastic, fabrics, pesticides and to purify water supplies.

除此之外，氨还用作制冷剂气体，以及用于制造塑料、织物、杀虫剂和净供水。

It was stumbled upon accidentally in 1938 by a 27-year-old American chemist named Roy Plunkett, while he was trying to develop a non-toxic refrigerant fluid for DuPont, a chemicals company.

它于1938被一位27岁的美国学家偶然发现，他的名字叫做 Roy Plunkett，当时他正在为杜邦公司开发一种无毒制冷剂，那是一家学公司。
