Principles of Refigeration

We were three weeks and three days without AC this summer during the brutal month of June where there were numerous 100+ days. I had four window AC units and 13 fans trying to keep things cool with all the shades down.

Speaking with a number of AC vendors, it became clear to me that I did not understand all the different components of an AC system. It is also became crystal clear that the AC vendors I was speaking with were not gifted in terms of explaining the technical components of an AC system.

I went to youtube and found this old, but great video on the principles of refrigeration.
