How does a car's refrigerant work?
This heat, together with the heat picked up by the refrigerant in the evaporator, is expelled by the condenser to the air that is flowing across it from outside the car. The refrigerant then cools and changes phase from gas to liquid.
Which part of the car expels heat?
Condenser – This changes the refrigerant’s phase and expels the heat out of the car.
What is the name of the substance that carries heat out of a car?
Refrigerant – A substance called R-134a (newer models) or R-12 freon (older cars), the refrigerant carries heat out of the car.

What does the AC condenser do?
Making sure the condenser is operating properly is super important because it affects the operation of the entire AC system. The AC condenser is an essential Ac system component typically found on all newer vehicles. It converts the high-pressure refrigerant coming from the compressor to a high-pressure liquid form, through a condensation process. This happens in a heat exchange process where the refrigerant heat is expelled and exchanged with the outside air.
What is the purpose of a car condenser?
The car condenser is a vital component of the AC system that converts refrigerant from gas to liquid state so it can travel through the air conditioning system. The condenser works as a heat exchanger, and during the conversion state, a tremendous amount of heat is forced out of the refrigerant. Suppose the AC condenser clogs or is damaged; it will ...
What happens if a condenser leaks?

Where is the AC condenser located?
The condenser is normally mounted just in front of the vehicle�s radiator. It receives the full flow of ram air from the movement of the vehicle or airflow from the radiator fan when the vehicle is standing still. The ac condenser is poorly protected from the road debris.
What is the difference between an evaporator coil and a condenser coil?
The difference between them is that the evaporator coil absorbs heat from the surrounding area we need to cool down and the condenser coil rejects all the heat absorbed at the evaporator and compression action of the ac compressor.
How does a condenser change temperature?
The gas leaving the compressor, flowing through the discharge line, and entering the condenser is so hot compared with the surrounding air that a heat exchange between the hot gas and the surrounding air begins to occur immediately. The air being passed over the condenser is 95 F, compared to the near 200 F gas entering the condenser. As the gas move through the condenser, it begins to give up sensible heat to the surrounding air, which causes a drop in gas temperature. The gas keeps cooling off, or desuperheating, until it reaches the condensing temperature and the change of state begins to occur. The change of state begins slowly at first with small amounts of vapor changing to liquid and gets faster as the vapor-liquid mixture moves through the condenser. This is a latent heat process, meaning that even though heat in Btu is being rejected from the refrigerant, the temperature is staying constant.
Why is my AC condenser leaking?
The ac condenser is poorly protected from the road debris. Road debris hitting the ac condenser coil is one of the main causes of condenser leaks.
What happens when a refrigerant is 100% saturated?
When the condensing refrigerant gets about 90% of the way through the condenser, the refrigerant in the pipe becomes pure saturated liquid. If any more heat is removed from the 100% saturated liquid, it will go through a sensible heat rejection process because no more vapor is left to condense. This causes the liquid to drop below the condensing saturation temperature. Liquid cooler than the condensing saturation temperature is called subcooled liquid.
Which type of condenser is the most efficient for heat transfer?
The Parallel flow condenser (PFC) is the most efficient style of condenser for heat transfer because the fins stay in contact with tubes and refrigerant can flow through multiple tubes at the same time .This design provides the best possibility for the refrigerant to release heat .The PFC design uses multiple port tubes and corrugated metal fins with louvers.
What Is a Condenser and What Does It Do
A condenser is in the front of the radiator behind the bumper. Its main function is to help cool and dehumidify the incoming air, making it more comfortable for you and your passengers. The conditioner also reduces your risk of getting sick due to bacteria and mold that grows when in humid environments.

Why Water Leaks From the Condenser
The condenser is located on the back of the engine and its job is to bring down the temperature of the engine. It’s crucial not to overlook any leak coming from the condenser as that leak will cause corrosion, which can lead to other significant problems.
Signs That You May Need a Replacement
It is possible that you may need a replacement if water starts dripping out. You can check the radiator levels and make sure there are no leaks. If you find either of these problems, get your car checked by a professional!
Conclusion
Fixing a hole in the condenser of your car’s air conditioner can be tricky, but this article should help you get started. If you notice water dripping out and are unsure on the cause, measure any leaks with jug or radiator levels to see if anything is wrong.
How does a car condenser work?
Here’s how it works: refrigerant is pumped from the AC compressor into the condenser as a hot gas. Air flowing through the condenser cooling fins reduces the temperature of this hot, gaseous refrigerant and it the refrigerant gas “condenses” into a liquid which is then metered by a valve into the evaporator in your car’s passenger compartment. In the evaporator, that liquid refrigerant flashes (boils) back into a vapor because it is absorbing heat from your passenger compartment. The vapor containing the heat is then drawn into the “low” side of the compressor which compresses it back into the condenser, starting the refrigerant cycle all over again.
What is AC condenser?
AC condensers are a critical component of your vehicle’s air conditioning system. The AC condenser transfers heat from the refrigerant to the atmosphere and thus is comparable to your engine’s radiator insofar as function.
How high pressure is AC?
Warning: the AC system is under very high pressure, up to several hundred PSI when operating, and thus you can be seriously injured (blinded or suffer permanent frostbite burns) if the refrigerant gas contained within is not recovered properly.
Why does refrigerant flash back into a vapor?
In the evaporator, that liquid refrigerant flashes (boils) back into a vapor because it is absorbing heat from your passenger compartment. The vapor containing the heat is then drawn into the “low” side of the compressor which compresses it back into the condenser, starting the refrigerant cycle all over again.
