Central Air Conditioning

Central Air Conditioning systems are connected to the distribution system and cool on the same principle as a refrigerator. They remove heat from within a structure and release it outside. There are two main parts in an air conditioner – the evaporator and the condenser. The evaporator sits inside the ductwork and absorbs heat from inside air into the refrigerant. The condenser, the other main part, sits outside of the house and looks like it’s doing all the work. Actually, it’s only doing half the job. Air conditioners have become very energy efficient. Today’s a/c units range on average from 13 seer to 18 seer, the higher the seer level the more energy efficient.

Before refrigeration air conditioning was invented, cooling was done by saving big blocks of ice. When cooling machines started to get used, they rated their capacity by the equivalent amount of ice melted in a day, which is where the term “ton” came from sizing air conditioning. A ton of cooling is now defined as delivering 12,000 BTU/hour of cooling. BTU is short for British Thermal Unit (and is a unit that the British do not use) The BTU is a unit of heating – or in this case, cooling – energy. It’s more important, however, to keep in perspective that a window air conditioner is usually less than one ton. A small home central air conditioner would be about two tons and a large one about five tons.
