The compressor is the pump part of the system that moves the cooling solution, Freon, through the auto air conditioning system Tucson Arizona Air Conditioning Repair . While moving through the system, the Freon, which is a gas and a liquid, is forced through various sized metal and rubber hoses and tubes, through what is known as an expansion valve. This steady pressure and condensing and expanding of the Freon makes it get extremely cold within the metal and rubber hoses. As the Freon moves into the dash area of the car, it is relocated into a metal tube system that is called the evaporator core.
This system is comparable in function to a radiator, nonetheless, the extremely cold Freon within the interior of the metal tubes in the evaporator core cools the air that the air conditioner fan blows from the back of the dash to the front. This cooled air is then blown into the passenger area of the car through the vents located in the dash.
The control on the dash that the driver or passenger can readjust doesnt control the temperature of the evaporator core, rather, it controls how much air is blown throughout the core. The greater the amount of air, the more cold air that is pushed into the cars cab or passenger area. More sophisticated auto air conditioning systems have a thermostat that automatically adjusts the fan and controls the temperature of the passenger area. As the temperature rises, the thermostat sends out a signal to the fan to speed up and produce more cold air, decreasing the temperature.
Auto cooling systems likewise get rid of heat from the car with the Freon that is returning from the evaporator core to the condenser. This is done at the front of the engine, normally close to the radiator. The warmed Freon is transferred to the condenser, which is like the evaporator core, however, instead of allowing the cold Freon to cool the air, it permits the hot Freon to release the heat to metal fins, then a fan blows this heat away from the engine. In this way, the auto cooling system works as both a cooling and a heat removal system as the Freon circulates through the hoses and metal condenser.
