How Your Home Air Conditioning System Works

In order to keep household costs down it is important to understand how your air conditioning system works and how to maximize its efficiency. Though there are several types of air conditioning units, most homes have either window units for small areas such as one room, or split-system units which include wall-mounted and central air systems.

Contrary to popular belief, rather than just blowing cool air into your home, the air conditioner takes the warm air from your home, cools it, and cycles it back in. This continues until it reaches the temperature set by the thermostat.

They both run through the same cycle, which uses a chemical, often referred to as Freon, that converts from a gaseous form, to a liquid form, and back to a gas. The Freon serves to take heat out of the air in your house and transfer it to the outside, leaving cooler air behind inside.

The basic parts of any air conditioning system include a compressor, condenser, and an evaporator. In a split-system unit the compressor and condenser are housed in the condensing unit outside, with the evaporator indoors, whereas a window unit will have all three components in the one unit.

The Freon, beginning as a gas, cool and low-pressure, first goes through the compressor, where it is basically squeezed. This pushes the molecules closer to each other, raising the energy and temperature, so now it is a hot gas, at high-pressure, which goes to the condenser.

The condenser has metal fins which help the heat to dissipate, like the radiator in your car, so that it becomes much cooler and is now a high-pressure liquid, and heads for the evaporator. As it enters the evaporator, the pressure drops quickly causing it to change back to a gaseous form.

During this process, the Freon absorbs heat out of the surrounding air, assisted by more fins similar to those in the condenser. Now it is again a cool gas under low pressure and starts the cycle over. The air inside the house is pulled ,via a fan, through the vents and across the evaporator where the heat is absorbed from it. Then it is returned to the rooms of your home.

Many of the ways to increase the efficiency of your air conditioning system involve just reducing its workload by removing and blocking heat from your home with alternative methods. You can block heat by putting tint or other heat barriers on your windows, adding a radiant barrier in the attic, or simply upgrading your insulation.

Removing heat from your home can be done by using roof vents or ceiling fans, or controlling the airflow by opening the lower windows on the side of your house facing the wind and the upper windows on the opposing side, which draws the warmer air out. Whatever your methods, prudent use of your home's air conditioner saves money and energy, which is better for everyone.
