在这个温度范围内，通过蓄热器循环的水能够提取足够的热量来温暖住宅、商业和工业空间。

Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces.

温度很少超过32华氏度，在这个温度下水会变成冰。

Temperatures seldom go above 32°F, at which water turns into ice.

在这个温度下，沙门氏菌不会复制。

At that temperature, salmonella can't multiply.

And so an experiment said the gas didn't increase its temperature when it expanded the vacuum.

这个实验告诉你,气体在向真空膨胀的过程,中温度没有升高。

We call that inversion because on one side you end up cooling if you compress.

因为在这个温度的一边,当你压缩气体时气体降温。

But now, so this is where the refrigeration comes in. So if you take a gas, and you're below the inversion temperature and you make it go through this irreversible process, the gas comes out colder from that side than that side.

这就是冰箱的原理,如果在低于转变温度,的情况下我们将气体经过,这个不可逆过程,气体出来的温度将比这边低。
