Because hot air rises to the top of the room, the air conditioning intake valve draws in air that is floating higher up in the room and the outflow valve drives out chilled air to the lower strata of the room. All throughought the cooling process, a thermostat, positioned by the home owner, monitors the temperature in the room. When it drops below a pre-set level, the air conditioner turns off. The air conditioner turns back on when the temperature rises again

The Air Conditioner's Evaporator

Inside the air conditioner's evaporator, the liquid is allowed to expand. As it does so, it evaporates into a gas. This part of the tubing is indoors. As the low temperature gas flows through the evaporator a fan blows hot room air across the tube. The gas absorbs the heat and the room air, now cooled down, is blown back into the room. The heated gas next flows back into the air conditioner's compressor and the cycle begins again. As indicated by the flow patterns, the evaporator is in the part of the tubing that runs inside the dwelling and the compressor and condenser are in the parts of the tubing outside the house.

The Air Conditioner Compressor and Condensor

The air conditioner compressors compresses Freon in its gaseous state. As the gas is squeezed together, its molecules bunch together; it becomes hot, and becomes a high-pressured gas. Now the compressed gas travels through the condenser. The condenser is a set of coils, which permits the hot refrigerant to lose its heat. It is visible as the set of metal fins seen on the outside of a window air conditioner. As the hot gas circulates into the condenser, a fan blows air across the tubes and then to the outside. The warmth from the gas radiates into the moving air and out the house, and this assists in the cooling process. As the refrigerant leaves the condenser it has transformed to a liquid. The liquid now flows into the evaporator through a tiny hole.

Air conditioners use chemicals that readily convert from a gas to a liquid and vica versa. The compound, usually Freon, is termed the "refrigerant," and it flows in an enclosed circular tube.
