Recharging a Car's AC The High-pressure Side All automotive air conditioning systems are (nearly) closed loops with a high-pressure side and low-pressure side. We'll start with the high-pressure side as it leads from the engine to the passenger compartment: Compressor: The compressor is a pump driven by a belt attached to the engine's crankshaft. How Does a Car's Air Conditioning Work? Any AC system requires a refrigerant, such as R-134a. Your vehicle's compressor, powered by the serpentine belt, compresses the refrigerant into a liquid, putting it into a high-pressure state.

Power Steering Stop Leak. Bosch Iridium Spark Plugs. Understand your car's AC system with this informative video diagram, tracing the refrigerant's path through key components. If you look at the diagram above, you will see the arrows which show the direction that refrigerant flows through your AC system. There are slight variations between some systems, but this diagram is a good overall view of a generic AC system. This setup is typical for most imports and a few domestic cars. The diagram below shows the entire system and refrigerant flow (high pressure in red, and low pressure in blue). These systems are closed (sealed) which continuously re-circulates the refrigerant. A receiver dryer or an accumulator is used to filter and remove moister from the refrigerant to help prevent the system from being damaged by rust or corrosion. Automotive air conditioning (A/C) systems have become more complex, making DIY repair more difficult. Strict environmental regulations also make repairs more costly and complicated. The most common air conditioning parts are the compressor, condenser, evaporator, orifice tube, thermal expansion valve, receiver-driver, and accumulator.

TYPICAL AUTOMOTIVE A/C SYSTEM DIAGRAM *Automotive A/C systems may vary from one application to another. Consult the owner's manual for system specific information. Low-Side Service Port There are five main parts of a car A/C: Compressor Condenser Thermal expansion valve or orifice tube Evaporator Accumulator or receiver/drier Each of the parts is connected by tubing or hoses to form a closed loop. Through that loop runs refrigerant, which is what really does the work of cooling down the air. Learn how a Orifice Tube A/C system works on a mobile vehicle. This is a beginning lesson on mobile A/C for anyone starting to work on Air Conditioning on ca. 89K views 4 years ago The 2 main A/C systems explained: Orifice Tube/Accumulator System vs. Expansion Valve/Drier System.

Automotive Ac System Diagram And Description
Displacement is controlled by a bellows actuated control valve located in the rear cylinder head. This control valve senses and responds to the system suction pressure or A/C system demand. Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable. How Does AC Work in a Car? 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.
The car A/C works in two cycles: Refrigeration and Evaporative Cooling (evaporation and condensation). The primary purpose of the car air conditioner is to make the cabin ambiance comfortable for the occupants. Firstly, Air Conditioning is the process of making the air comfortable for the car's occupants. Previous research has addressed the energy management of the A/C system for vehicles with traditional internal combustion engines (ICEs) [4] [5], where the A/C compressor is belt-driven by the ICE.
CAR AIR CONDITIONING /AC/ SYSTEM FUNCTION COMPONENTS
Table of Contents Car Air Conditioning AC System | Function , Components , Working The components used in automobile AC are- 1. Compressor - 2. Condenser - 3. Expansion valve- 4. Evaporator - 5. Receiver-Dryer- Receiver/driers serve three very important functions: 6. Refrigerant - 7. Pressure Regulating Devices 8. Orifice Tube 9. Accumulator An automobile or car air conditioning system works to cool the inside air of the vehicle cabin. The main purpose of the auto air conditioning system is to make the internal temperature of the air lowered and comfortable for occupants. The automotive air conditioning system cleans, dehumidifies, and circulates the interior air of the car cabin.
