If you are someone who has always been curious about how car AC works, continue reading below for a deeper look into air-conditioner theory, system components and system operation. The air-conditioning system in a car works by manipulating refrigerant between a liquid and a gaseous state. As the refrigerant changes states, it absorbs heat and humidity from the vehicle and allows the system to give off cool, dry air. To change the refrigerant between a liquid and a gaseous state, the air-conditioning system works to control pressure and temperature. In the past, automotive air condition systems used R as the refrigerant. R aka Freon is a very effective CFC-based chlorofluorocarbon refrigerant that is not flammable and not poisonous to humans. Manufacturers transitioned to Ra in the mids.

When it comes to car air conditioning, most people take it for granted. Without your air conditioner, driving in warmer climates like Australia will become an unbearable experience for the common driver. Have you ever wondered how car air conditioning works? Well the car air conditioner has pretty much worked the same way for its entire existence in the modern world and that is, it cools and removes humidity from the air. The compressor is connected to an evaporator which cools the air as it passes through. The cooled air is then sent through vents in your car cabin. All car air conditioning systems are fully closed loops. In one full loop, it changes the state of matter 3 times with a high-pressure side and a low-pressure side. The refrigerant is drawn into the compressor as a low-pressure gaseous form. Once the gas is in the pump it is put under extreme pressure psipsi and is forced out to the condenser.

Automotive AC technicians diagnose and repair AC systems on a regular basis at dealerships and independent shops. Once the gas is in the pump it is put under extreme pressure psipsi and is forced out to the condenser. Schedule An In-Person Tour, car a/c diagram.

You probably don't think of your car's air conditioning system very often. But if it broke down, you'd definitely miss the cool air. So, how does AC work in a car? Automotive air conditioning has been with us longer than you might think. Packard invented automotive AC all the way back in , and in it was the first car company to offer factory-installed air conditioning. Of course, this early system didn't have a thermostat, but it was better than not having anything at all.

The car AC system diagram illustrates the components and flow of air conditioning in a vehicle. The car AC system diagram provides a visual representation of how the various components work together to cool and circulate air inside a car. It includes key elements such as the compressor, condenser, evaporator, and expansion valve, illustrating the path of refrigerant as it undergoes compression, condensation, expansion, and evaporation to remove heat from the cabin. By understanding the car AC system diagram, car owners and technicians can diagnose and repair issues related to air conditioning, ensuring optimal comfort and performance on hot days. The car AC system comprises a compressor, condenser, expansion valve, and evaporator.

Phone Required. I am not convinced since the cooling is good while running.

The evaporator looks similar to a radiator, with its coil of tubes and fins, but its job is to absorb heat rather than dissipate it. Had a novice question on this: Quote: Originally Posted by Jeroen On a clutch only system the compressor clutch is activated based on the low pressure part of the system. A fan blowing over the outside of the evaporator coil blows cool air into the passenger compartment. Learn about how long it takes to become an automotive technician, salary, job outlook and more.

The system looks complicated, but it's really quite simple. Once you know how it delivers cold air you will be better informed when problems occur and how to fix them, or understand more on what a garage is telling you when having it repaired. Your heater and air conditioner HVAC have three jobs, cool the interior of the car down, heat the interior up and defrost the windshield.

With classes starting every weeks, no need to wait to start your career. The expansion valves controls the amount of refrigerant flowing through the evaporator based on the upstream temperature of the refrigerant. If a leak is present in any component, simply recharging the system with new refrigerant will be at best a temporary fix. Please give your expert opinion. I do not want to change the compressor since I will be changing the car soon. Then cooled down, it is led through a drier absorbing any moisture. Skip to content. But while in neutral and first gear, the compressor seems to be not working, the cooling drastically reduces and in case of extended duration in idling and first gear crawling, it starts blowing hot air.
