Imagine a situation where you are decked in traffic snarl in hot summers. You are all sweaty and exasperated with the moment and your sweat-absorbed clothes make a damp spot on the seat. Your feet get stuck to the central vinyl upholstery or are miffed by the velvet. Well, this situation is everyone’s nightmare, whether it is a driver or passenger. The sole relief and respite from this plight is a good car air conditioning. This facility has become a ubiquitous feature in almost every car today. What started off as plain-shot refrigerant with chlorofluorocarbons affecting the ozone, has become today’s refined, safer and newer refrigerant.

The fundamental aspects:
Well, it appears to state conditions in the air. The mechanism not only cools things down, but significantly reduces humidity or moisture content.
- All air conditioners entail the same functional pathway regardless of the installation ambit like the car or a building. The three core parts are compressible, evaporator and condenser.
- The freezer or fridge in car air conditioning is an air conditioner in itself. It’s a field or electronic segment in its own right. Many people do not realize the fact that turning on the system actually reduces the volume of miles per gallon of the vehicle.
- There’s energy involved here to remove the moisture and heat from the air inside the car. It is the consumers’ petrol owing to the additional engine load.
The core components:
The primary principles of car air conditioning are condensation and evaporation followed by expansion and compression. They underline thermodynamics to the physicists and engineers.
- The first round of evaporation denotes the little surgical prints or spirits rubbed against your hand’s back. It feels cold. The reason is evaporation and the back of your hand’s spirit begin to evaporate. When it does, it takes away all the heat away from your skin’s surface.
- In condensation, it’s like someone walking in from the cold into another domain wearing glasses. The glasses shall always steam up because the takeaway’s moist air cools once it touches the cold surface of your glasses. The air entails less ability to retain moisture; hence it condenses and changes into water on those glasses.
- With compression heat, you need to know that all gases will eventually convert to liquid. Expansion cooling is like a deodorant. You know it feels cold when you spray it. The propellant inside expands in the volume very quickly to effectuate this.

Now keeping aside, the surgical spirits and takeaways that form the basic ideas, the most important question is how do all these fit into effectuating your vehicle’s vent to blow cold?
- The answer lays in the crux of car air conditioning flexible hoses and hard tubing deices connecting the actual components of air conditioning inside. The core principles are the physics behind its functionality. The five main components in the whole system are compressor, receiver-dyer, expansion valve, condenser and evaporator.
- The former is a pump propelled by a belt looped to the crankshaft of the engine. When you draw the refrigerant into it, it stays is a low-intensity gaseous form. When you turn on the air con system, the compressor pumps the all-important, high pressure refrigerant vapor to the condenser.
- The condenser is a radiator type device that radiates heats out of the block. The air flowing in this layer and twisting tubes cool the incoming refrigerant and helps to convert to liquid again.
Primary repair steps:
Weak airflow and leaks are the main causes that affect car air conditioning. Detection is a critical step for maintenance. You need to check the clogged valve and compressor clutch along with the brown fuse ambit.
We hope that the above mentioned tips will help you to understand the fundamental aspect of car air conditioning.
