The system starts with a fan that blows the warm air in your room over a coil that's filled with the liquid.

该统由一个风扇启，风扇将热空气吹过充满制冷剂的盘管。

And as the chemical condenses, it releases heat energy – that heat is then transferred to the outside air that's blowing over the coils.

当化学物质凝结时，它会释放出热能——这些热量随后被传递到外面的空气中，空气盘管上。

There are even designs in the works that take out the fluid filled coils altogether, and use metal rods that are heated and cooled using magnetic fields.

甚至有的设计抛弃了充满液体的盘管，改为使用通过磁场进行加热和冷却的金属棒。

Then, the air could blow over a set of coiled pipes with a chemical inside that could either heat or cool the air, to alter its humidity.

然后，空气吹过一组内部含有化学物质的盘管，这种化学物质可以加热或冷却空气，以改变其湿度。
