Air conditioners use chemicals that easily convert from a
gas to a liquid and back again. This chemical is used to
transfer heat from the air inside of a car cabin to the
outside air. The machine has three main parts. They are a compressor, a condenser and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. The evaporator is located on the inside the cabin.That's the part that cools your cabin.
The working fluid leaves the compressor as a hot, high
pressure gas and flows into the condenser. If you looked at
the air conditioner part outside the cabin in front of the
radiator, look for the part that has metal fins all around. The fins act just like a radiator in a car and helps the heat go away, or dissipate, more quickly.
ABOUT US
When the working fluid leaves the condenser, its temperature is much cooler and it has changed from a gas to a liquid under high pressure. The liquid goes into the evaporator through a very tiny, narrow hole called expansion valve. On the other side, the liquid's pressure drops. When it does it begins to evaporate into a gas. As the liquid changes to gas and evaporates, it extracts heat from the air around it. The heat in the air is needed to separate the molecules of the fluid from a liquid to a gas. The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air.
By the time the working fluid leaves the evaporator, it is a cool, low pressure gas. It then returns to the compressor to begin its trip all over again. Connected to the evaporator is a fan that circulates the air inside the cabin to blow across the evaporator fins.
There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the cabin through other ducts usually at the dashboard.
This continues over and over until the room reaches the temperature you want the room cooled to. The thermostat senses that the temperature has reached the right setting and turns off the air conditioner. As the cabin warms up, the thermostat turns the air conditioner back on until the cabin reaches the temperature.
