Car Ac System Explained

The air conditioning system in your car is comprised of a compressor condenser expansion valve and evaporator.

Car ac system explained.

Air conditioning now comes as standard in almost all newly produced cars and is a feature that most car owners have come to expect. The compressor of the car air conditioning system is driven by the crankshaft of the engine through the belt drive. How does a car s air conditioning work. Any ac system requires a refrigerant such as r 134a.

This is due to the rapid expansion of the compressed gas. The compressor is a pump driven by a belt attached to the engine s crankshaft. Recharging your ac is a temporary fix to a likely bigger problem. Car air conditioning is a system within your car that allows you to cool the interior air of the vehicle in hot weather providing for a cooler environment for the occupants.

When your car s air conditioning ac begins to lose power and doesn t blow cool air it may be time for an ac recharge. We ll start with the high pressure side as it leads from the engine to the passenger compartment. This pressure forces the liquid out of the compressor through the hoses in your ac hose assembly which. Condenser it is the device looks like a small radiator and is used after the compressor as it provides condensing i e.

If you have ever used a can of compressed air to clean computer components you will know that the bottle gets very cold in a short amount of time. When the refrigerant is drawn into the compressor it is in a low pressure gaseous form. Recharging your ac means adding more refrigerant to your ac system to allow the air to start blowing cold again. All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side.

Lowers the temperature of the high pressure and high temperature liquid refrigerant sent by compressor through forced convection provided either by. Your vehicle s compressor powered by the serpentine belt compresses the refrigerant into a liquid putting it into a high pressure state. This system is controlled by a main computer which sits in the dash and also houses the controls for the mode and temperature settings. Your heater and air conditioner hvac have three jobs cool the interior of the car down heat the interior up and defrost the windshield.
