Ways to a Happy Driving
When driving or riding a car, one of the first things we consider is comfort. Part of that comfort is knowing that you’ll be kept cool inside the car when the weather is scorching outside; and that you’ll be kept warm when the weather is freezing on the outside. This is the job of the vehicle’s air conditioning and heating systems .
The air conditioning system removes the heat that makes us uncomfortable and returns the air to the car's interior in an "un-heated" condition. Air conditioning, or cooling, is really a process of removing heat from an object (like air). It works this way: a compressor circulates a liquid refrigerant called Refrigerant-12 (more commonly known as Freon). The compressor moves the Refrigerant-12 from an evaporator, through a condenser and expansion valve, right back to the evaporator. The evaporator is right in front of a fan that pulls the hot, humid air out of the car's interior. The refrigerant makes the hot air's moisture condense into drops of water, removing the heat from the air. Once the water is removed, the "cool" air is sent back into the car's interior.
On the other hand, the heater core - a smaller version of the auto radiator, is what helps keep our toes warm when it's cold outside. The heater core is mounted under the dash board. Some of the hot coolant is routed through this little radiator, by more hoses. A small electric fan is also mounted there especially for the purpose of directing the heat inside the car. The principle is exactly the same as the one used in the radiator for your engine, except that the heat is released inside the car instead of outside. Most engines use the heater core to warm the air coming from the air conditioner if the dash setting is not on "cold". More efficient designs don't do this because it makes the engine work harder than it has to. They cycle the compressor on and off to lessen the cooling output.
