subject: Science behing the comfort-Air conditioning [print this page] Many of us have become spoiled with all the air conditioning that is around here today. In fact, some of us even dislike it at restaurants and movie theaters because it is too cold! People a hundred years ago would probably be in shock at how easily we accept this luxury and sometimes hold a slight distaste for it.
Since many take this cool air for granted, the operations of an air conditioning machine are not widely known. A few facts about air conditioners include:
The concept of air conditioning is thought to go back as far as Ancient Rome, when water was used in the walls of homes to cool them down.
Air conditioning is not just putting cold air in a room, it is actually removing the existing hot air from the room, therefore making it cooler.
There are usually two components of central air conditioning-an outside one as well as an inside one. The outside one is the condensing unit and it is where the refrigerant, which is in a gas form, is compressed to a liquid. This liquid then travels to the inside unit and is released on a coil. When the pressure is taken off, the refrigerant reverts to gas state. This evaporation process absorbs heat, therefore it takes the heat from the area making the area cool.
In the world of central air conditioning, SEER stands for Seasonal Energy Efficiency Ratio. Air conditioners are rated with a SEER number, and the higher the number, the more energy efficient the unit.
Central air conditioning is the most convenient way to keep your house cool during the warm summer months. Now you have more information to make an informed decision about purchasing a central air conditioning unit!
