Radiators Help Your Car’s Air Conditioner

In the context of simplicity, nothing can be more enjoyable than driving in your car with the air conditioners open to cool your tired, perspiring bodies (especially in this tropical country’s weather). That’s why your car’s air conditioning system is one of the top priorities of your car’s maintenance next to making sure it runs from point A to point B efficiently and safely. Speaking of important components of your car, the radiator is vital to its engine. Its primary purpose – which is to cool your engine, should not be overlooked.

Overheating is a major dilemma and a terrible thing to have if you own a car. It can cause everything from something as simple as being late to your destination to something a lot more serious like an accident. But a common misconception is out there for some average Joes. (Car buffs don’t need to know about this basic thing). A lot of people think that radiators help your car’s air conditioning system. And I am here to tell you in this article that it is a misconception. Allow me to elaborate.

First off, let’s separate the two components. What does each one do? In doing so, you’ll know how they are not related to each other. Don’t worry, I won’t get too technical to keep things as simple and as understandable as can be.

Car Air Conditioning SystemYour car’s air conditioning system works with the same purpose just like any air conditioning system – to give off cool air. And the way it “makes” cool air is by making a cycle of condensation and evaporation within its own system with 5 distinct components. There’s the evaporator which sits inside your dashboard which gives off cool air, the compressor to keep the refrigerant cycling, a metering orifice, the receiver-dryer which removes moisture, and the condenser which sits in front of your car’s radiator. With all these parts making a cycle of condensation and evaporation, it removes heat – which “makes” coolness to be blown by a fan of your air conditioning system.

How does your car radiator work? More specific than just, “to cool the engine” is saying this. It transfers the heat from the coolant (which came from a very hot engine) to the open air which makes the coolant lose heat and become cooler to go back into the engine where it will take some if its heat into the open air again and again in a cycle.

What can you get from this? It’s pretty obvious. To put it simply, the air conditioning system deals with cooling the internal of the car with the driver and passangers inside, but the radiator cools the engine. Probably it’s a common misconception because a part of the air conditioning system (the condenser) sits in front and very close to the radiator that it makes some people think they work with the same cycle. But actually, no. They do not work within the same cycle. Your car’s radiator has nothing to do with its air conditioning system. So there you go. That’s why any problem involving either of the two must be treated as if it were coming from two separate working parts of the engine.
