A geothermal heat pump works like a regular heat pump, only it pulls heat out of the ground instead of the air.

地热泵的工作方式与普通的热力泵相同，区别只是地热泵是从地下吸热而不是从空中。

You're taking the air inside of the pump and you're compressing it. You're doing it so fast that there's not enough time for heat to come out of the gas that's inside the pump towards the walls of the pump.

你把空气吸进气筒里并且压缩它,你的动作很快以至于,没有足够的时间让热量,从气筒里面跑出来,传递到气筒壁上。

But you don't compress it so quickly that you're not in there reversible process so you compress that if you were to feel the temperature of the air and you can feel it through the nozzle gives you an idea of the temperature of the air inside your bicycle pump.

但是压缩速度,也不能太快,否则就不是,可逆过程了,这样当压缩气体时,从喷嘴可以感受到,内部气体的温度。

This eliminates the need for an air pump, resulting in a small inhaler the size of a Magic Marker.
