You've told us you love your job and you think man's best invention is air conditioning. You have a very positive view of Berkshire Garage Doors and have made an incomprehensible posting in another thread.

Now you'd like to know how air conditioners work.

Something odd here.

I suggest you use Google, if you are genuinely interested to find out.
