We're not all professional mechanics, and not all of us are driven by passion for fixing things and fiddling with our cars on our own. Still, it's good to know the basics of how your car works that makes your life easier on a daily basis.
People often can't tell the difference between car AC coolant and car AC refrigerant. Mistaking these two may lead to catastrophic consequences for your car, so it's best to get it sorted out.
It's often mistaken that the coolant keeps your car cabin from getting too hot, but that couldn't be further from the truth. Car AC coolant doesn't exist.
As you probably know, when the engine in your car is running, it generates tremendous amounts of heat so it needs to be cooled down. The cooling system of your car prevents your engine from overheating by utilizing a coolant, among other things.
To keep the engine temperatures at steady and constant values, coolant is usually a 50/50 mixture of antifreeze and water.
Upon starting the engine, a water pump will also start circulating the coolant through the radiator and the engine itself. Then the thermostat opens to control the flow of coolant through the radiator so that the engine temperature can be kept at a constant level.
The flow of coolant usually does not occur when the engine is cold in order to make it easier to warm up quickly. The thermostat will then open each time it's needed to keep the engine temperature constant.
It may seem illogical, but car coolant helps keep you warm during the winter. The aforementioned water pump circulates the coolant to the heater core, which is located just under the dash of your car.
After that, the blower fan blows the air over the heater core and through all the ducts, so that it provides your cabin with hot air.
Getting back to the main issue, what most people refer to as car AC coolant or car air conditioner coolant is actually car AC refrigerant. A refrigerant is a gas or liquid with a low boiling point.
The refrigerant in your car AC is very efficient in absorbing heat, and therefore cooling your car cabin. This happens through a few thermodynamic processes in a closed-loop car AC system. The most expensive part in the car AC system is the compressor. This is where the refrigerant gas is compressed.
Then the pressurized gas is fed to the condenser where the gas condenses and leaves as liquid, still highly pressurized. At this stage the high-pressure liquid is just looking for an excuse to vaporize, and it gets the opportunity when it goes through an expansion valve in the car AC system. The property of the car AC Freon is such that it turns into a low-pressure gas at water freezing temperature or 32F.
To facilitate heat transfer with the hot blower air, the cold Freon gas enters an evaporator core. The blower air is cooled before it exits the air ducts in the car cabin, and the spent car AC refrigerant or Freon is sent to the compressor to resume the cycle.
People often mistake these two when their car AC doesn't work properly. If you need to get your car air conditioner fixed, you should visit a professional mechanic to check for refrigerant leaks. Keep in mind, these aren't coolant leaks.
Good news is that car air con top up with new refrigerant is an easy and inexpensive process. In most cases it just needs new refrigerant and proper re-pressurization of the whole system. Be sure to check out United Tires for car air conditioner recharging if you’re in the greater Chicago area.
