Workers dealing with cooling systems and refrigerants are required to get a license.

处理冷却系统制冷的工人必须获得许可证。

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年被一位27岁的美国化家偶然发现，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，那是一家化公司。

A 1987 agreement called the Montreal Protocol banned a series of chemicals — mainly used in refrigerants and aerosols — believed to have reduced the thickness of the ozone layer.

1987 年签署的《蒙特利尔议定书》禁止使用一系列化物质——主要用于制冷雾——据信这些化物质减小了臭氧层的厚度。

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，氨还用作制冷体，以及用于制造塑料、织物、杀净化供水。

About 80% of the chlorine in the atmosphere is a legacy of chlorofluorocarbons, chemicals used in aerosol sprays and as refrigerants starting in the 1930s.

约80%的氯在中是氯氟烃的遗留物，这是从20世纪30年代开始使用的溶胶喷雾制冷。

These include air conditioners that can use heat pumps, and water, instead of chemicals like HFCs as a refrigerant.

其中包括可以使用热泵水，而不是像氢氟碳化合物这样的化物质作为制冷。

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，帮助冷却制冷液体。

The refrigerant comes into the evaporator as liquid and sprays out as gas, and that process needs energy.

制冷以液体形式进入蒸发器，然后像喷雾一样以体形式喷出，这个过程需要能量。

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

而冷藏所需的电力通常是由燃烧的化石燃料生产的，且制冷体也会进一步加剧候变化。

Cooling systems use gases called refrigerants. Such gases can affect the atmosphere if they escape.

冷却系统使用一种叫制冷的体。如果这些体逸出，可能会影响。

A 1987 agreement called the Montreal Protocol banned a series of chemicals – mainly used in refrigerants and aerosols – believed to have reduced the thickness of the ozone layer.

1987年签署的《蒙特利尔议定书》禁止使用一系列化物质——主要用于制冷雾——据信这些化物质减小了臭氧层的厚度。

The substance is unsurprisingly called refrigerant.

这种物质理所当然地被称为制冷。

This refrigerant is said to be less harmful to the environment than older cooling chemicals known as chlorofluorocarbons (CFCs).

据说，这种制冷对环境的危害小于被称为氯氟烃(CFCs)的较老的冷却化品。

The compressor drives the refrigerant through the cooling system, taking all that absorbed heat energy with it.

压缩机推动制冷流经整个冷却系统，同时带走所有吸收的热量。

Ajeigbe said one of the biggest problems is a lack of effective education and training about the possible harms of refrigerants.

阿吉格贝表示，最的问题之一是缺乏关于制冷可能危害的有效教育培训。

Some trained workers do follow environmental rules governing the use of cooling refrigerants.

一些训练有素的工人确实遵守了有关使用冷却制冷的环境法规。

The Nigerian government has approved restrictions on the release of refrigerant gases into the environment.

尼日利亚政府已批准限制向环境中排放制冷体。

Label CFC-11, the chemical in question used to be used in refrigerants, foam blowing agents, and aerosol sprays but it was supposed to be completely phased out in 2010.

标签 CFC- 11， 该化品曾用于制冷、泡沫发泡溶胶喷雾， 但本应在 2010 年完全淘汰。

And so, we were able to swap out the air conditioners and the refrigerants that had these nasty ozone-destroying chemicals with ones that didn't.

因此，我们能够将含有这些有害臭氧破坏化物质的空调制冷换成不含这些化物质的空调制冷。

So when a fan blows over the refrigerant, thermal energy transfers to the comparatively cold air outside.

因此， 当风扇将风吹过制冷时，热能便传递到相对较冷的外部空中。
