How does car AC work?
Before explaining how car AC works, let’s talk about the basic principles of air conditioning. Air conditioning works by removing heat and moisture from the air inside a closed space. This is achieved by the use of a refrigerant that circulates through a closed system of pipes and is compressed and expanded through various stages, changing from a liquid to a gas and back again.
In a car, the AC system is an accessory that is powered by the engine’s belt. When you turn the AC on, a compressor begins circulating refrigerant through the system. Here’s a closer look at the main components of a car’s AC system:
- Compressor: The compressor is the heart of the AC system. It compresses the refrigerant gas and pumps it through the system.
- Condenser: The condenser is located in front of the radiator and helps to release the heat absorbed by the refrigerant.
- Evaporator: The evaporator is located inside the car’s cabin and removes moisture and heat from the air.
- Expansion valve: The expansion valve controls the flow of refrigerant into the evaporator, which helps regulate the temperature.
The process of removing heat and moisture from the air begins as the refrigerant gas leaves the compressor and travels through the system. As the gas passes through the condenser, located in front of the car’s radiator, it gives off heat and becomes a high-pressure liquid. The liquid is then cooled as it passes through the expansion valve and into the evaporator. As the liquid expands, it turns back into a gas and absorbs heat and moisture from the air inside your car, which is then blown out through the air vents.
To maintain the AC system’s effectiveness, it’s important to have it serviced regularly. This includes checking the pressure, checking for leaks, and replacing the refrigerant if necessary. By doing this, you can ensure the AC system in your car will function properly and keep you cool on even the hottest days.

How Car AC Works
Before you hit the AC button, it’s essential to understand how car AC works. Understanding the principles of its operation can help you make informed decisions when using the system and identify potential problems.
Car AC systems work by transferring heat and moisture from the cabin to the outside. The process starts with a compressor, which compresses the refrigerant gas and converts it into a high-pressure, high-temperature gas. The hot gas moves to the condenser, where it dissipates the heat to the outside, resulting in a cooled-down, high-pressure liquid that flows to the expansion valve. The expansion valve regulates the refrigerant’s flow and reduces its pressure, causing the liquid refrigerant to expand and transform into cold gas, which moves to the evaporator. As the cold gas passes through the evaporator, it absorbs the heat and moisture from the cabin, cooling the air and removing humidity. The process repeats as the refrigerant gas is cycled back to the compressor.
| Component | Function |
|---|---|
| Compressor | Compresses the refrigerant gas and converts it into a high-pressure, high-temperature gas. |
| Condenser | Dissipates the heat from the gas to the outside, resulting in a cooled-down high-pressure liquid that flows to the expansion valve. |
| Expansion Valve | Regulates the refrigerant’s flow and reduces its pressure, causing the liquid refrigerant to expand and transform into cold gas, which moves to the evaporator. |
| Evaporator | As the cold gas passes through the evaporator, it absorbs the heat and moisture from the cabin, cooling the air and removing humidity. |
