The Workings of a Car Air-Conditioner

Air conditioning systems are a great way to cool down during hot weather. Air conditioners are a complex piece of equipment, and if you are not sure what to look for, then there is a chance that you will get yourself into trouble sooner than later.

If your car’s Air Conditioning Aldershot gets broken, you might need help from an auto mechanic.

An air conditioner is thus made up of several parts and components, including a compressor, condenser coil, expansion valve, evaporator coil, and blower motor. You may also see the presence of a capacitor bank. To keep all these parts working together properly, you must regularly check the different parts of your vehicle.

Air conditioning systems are very complex systems, made up of many different parts. These parts all require regular servicing to maintain them at peak efficiency. Some parts of the system may become clogged, causing the system’s airflow to slow. Over time, this will lead to a decrease in the cooling capacity of the system.

Regularly checking the system should help to identify any problems before they cause issues. When the system does not function correctly, it could mean that the system requires repair. A service technician will carry out a full inspection of the system, including a visual check of the compressor. If the system still fails to operate properly, it may be necessary to replace the unit.

How does your car’s air conditioning work?

When you start your car, the engine heats up the coolant inside the engine block. The coolant then circulates through the water jacket, cooling the cylinder walls. As the coolant returns to the engine block, its temperature drops, causing the compressor to run at high speed.

The compressor compresses the refrigerant, increasing its pressure. The compressed refrigerant enters the condenser, where the pressure falls, and the refrigerant turns to vapour. The refrigerant then flows to the evaporator, where it absorbs heat from the passenger compartment and converts it to a liquid again.

Different Parts of Car Air Conditioner


A compressor is an important part of any air conditioner system. Its primary function is to increase the pressure of the refrigerant before sending it through the condenser coil. Without a compressor, there would be no cooling effect. A motor usually drives a compressor, and the engine turns the belt that drives the compressor.


A condenser is a device that cools down the hot gas inside an engine. It is mainly connected to the radiator, and after cooling down the gas, it returns back to the engine and gets recharged. It reduces the gas’s temperature and pressure before entering the radiator.


An accumulator is a part of an automotive air conditioning system that stores excess refrigerant before returning it to the compressor. An accumulator prevents the liquid refrigerant from entering the compressor during engine startup. During normal operation, the accumulator provides additional capacity to store refrigerant until it requires it again.

Thermal Expansion Valve

A thermal expansion valve (TXV) is an electronic device that allows the flow of liquid refrigerant through a closed-loop system. TXVs are commonly used in automotive climate control systems to regulate the amount of heat transferred to the cabin.


An evaporator is a device that cools water through evaporation. The heat energy gets absorbed into the water and then released as vapour. Evaporators are primarily used in refrigerated cars, air conditioning systems, and other devices that need to remove heat from the water.


Refrigerants are compounds that absorb heat from the surrounding environment. Inside an air conditioning Aldershot system, refrigerants get heated and become liquid. When it comes in contact with the cold coil, it turns back into gas. As it absorbs heat from the surroundings, it becomes less dense and thus lighter.

This allows the refrigerant to rise and flow out of the compressor to the condenser. The condenser cools down the refrigerant to its gas phase, allowing it to move further to the evaporator. There, it sucks heat from the indoor air, turning it into a vapour and then moves to the compressor again.

Air Conditioner service

Our cars need regular maintenance, but we usually ignore the fact that our air conditioners also require care and attention. When you notice that your air conditioner isn’t cooling properly, it might be time to get it serviced.

If there are any leaks, then you’ll need to fix those first. Then you’ll need to check the filters. Finally, you’ll need to clean out the evaporator coil. Checking the air conditioner regularly is easy to prevent costly repairs down the track. It is also a great opportunity to check if there are any signs of leaks and other problems.

If you notice anything out of place, contact the service provider immediately. Topping up the refrigerant will help prolong your system’s lifespan and add a bit of extra capacity when demand peaks. Adding a couple of drops of lubricating oil to protect the compressor will help reduce friction inside the system and prevent damage due to heat buildup.
