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

处理冷却系统和制冷剂的工人必须获得许证。

The substance is unsurprisingly called refrigerant.

这物质理所当然地被称为制冷剂。

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

冷却系统用制冷剂的气体。如果这些气体逸出，能会影响大气。

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.

而冷藏所需的电力通常是由烧的化石料生产的，且制冷气体也会进步加剧气候变化。

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

制冷剂液体形式进入蒸发器，然后像喷雾样气体形式喷出，这个过程需要能量。

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

其中包括用热泵和水，而不是像氢氟碳化合物这样的化学物质作为制冷剂。

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剂气体。

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

压缩机推动制冷剂流经整个冷却系统，同时带走所有吸收的热量。

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

些训练有素的工人确实遵守了有关用冷却制冷剂的环境法规。

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，最大的问题之是缺乏关于制冷剂能危害的有效教育和培训。

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

据说，这制冷剂对环境的危害小于被称为氯氟烃(CFCs)的较老的冷却化学品。

As the refrigerant releases heat, it starts to liquefy.

随着制冷剂释放热量，它开始液化。

These could be a liquid noble gas, germanium and silicon crystals, a refrigerant, or other materials.

这些能是液态惰性气体、锗和硅晶体、制冷剂或其他材料。

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剂时，热能便传递到相对较冷的外部空气中。

And we’ll have to switch over to refrigerants that, even if they do leak, won’t trap heat.

而且我们必须改用即泄漏也不会积聚热量的制冷剂。

First, refrigerants can be potent greenhouse gases.

首先，制冷剂能是强有力的温室气体。

Hydrofluorocarbons are some of the most popular refrigerants.

氢氟烃是最常用的制冷剂之。

I mean, there is a huge industry, of course, that made these air conditioners and refrigerants that had these chemicals.

我的意思是，当然，有个巨大的行业制造了这些含有这些化学物质的空调和制冷剂。

It starts and stops frequently because of leaking liquid line, lack of refrigerant, dirty or iced evaporator and so on.

其频繁启停的原因包括液管泄漏、制冷剂不足、蒸发器脏污或结冰等。
