Part I: How Your AC Works

One of the most beloved of all appliances, especially in New York City in the summer is the air conditioner. IDT Energy would like to take readers on a little tour of how these wonderful devices work.  First off, it is good to know that air conditioners work the same way as refrigerators, the only difference being the scale on which they work. The main principle involved is the use of a volatile liquid, meaning a chemical that easily changes form liquid to gas and then back again. This is referred to as the coolant. The coolant is used to transfer the heat which is found inside the home, and remove it to the outside.

There are three main parts to an air conditioner. Two of the parts, the compressor and the condenser are usually found on the outside part of the air conditioner. The third part, the evaporator, is inside the house.
