Here in northern New England we don’t handle hot and humid weather well. The first heat wave of the summer always sends people scrambling to buy the few air conditioners that are in stock at Home Depot or Walmart. In fact, I was one of those scramblers a couple of weeks ago. This leads me to a new video from Reactions titled How Air Conditioning Works.

How Air Conditioning Works uses excellent drawings and narration to explain the inner workings of air conditioners. The video also explains the environmental impact of the chemicals that are used in air conditioners and the alternatives that are currently being explored.
