Brief Introduction to Auto Air Conditioning Compressors

 

Auto air conditioning compressor is the core component of the vehicle air conditioning system and is driven by the engine. As one of the core components that creates the necessary circulation in a vehicle's air conditioning system, its main role is to apply the necessary pressure (compression) to the vehicle's refrigerant to activate its heat transfer properties and change its temperature. Without it, your entire air conditioning system won't be able to perform its primary function of producing cool air inside your car.

Working Principle of Automobile Air Conditioning Compressor

 

 

Refrigerant

Freon is a commonly used refrigerant, which is a fluid that essentially turns hot air into cold air. This refrigerant and compressor are an important combination that work together. Your car's engine drives the air conditioner compressor, whose main job is to compress the refrigerant used to draw hot air inside your car's cabin.

 

Driving Method

Pulleys and V-belts drive the compressor that is connected to the vehicle's engine block. When you turn on the air conditioning system, an electromagnetic clutch activates the belt drive. The swash plate oscillates six double-ended pistons, which are responsible for intake and compression. Note that refrigerant flow is controlled by a reed valve. A thin mist of oil then circulates and mixes with the refrigerant to provide proper lubrication to the moving parts.

 

Refrigeration Process

Next, the air conditioner compressor draws gas from the refrigerant through the evaporator, causing the pressure to drop. The reduced pressure causes the refrigerant to evaporate at low temperatures, and the air conditioning compressor then absorbs the cold vapor and compresses it. During the compression process, the refrigerant gas is heated and pushed through the pipes into the condenser. Here it reliquefies and dissipates heat, then moves to an area where it cools. The refrigerant then absorbs heat from the passenger compartment. It returns to its gaseous state in the evaporator before being sucked into the air conditioner compressor.

Benefits of High Quality Auto Air Conditioning Compressors

A high-quality auto air conditioning compressor can not only provide you with coolness quickly, but also save you money, as follows:

Keep Cool

A car air conditioner compressor is vital to keeping your car or truck cool during the summer months. Without them, heat can quickly build up and cause failure. These compressors work by using refrigerant to cool the air and reduce its volume, thereby reducing the amount of energy required to keep your car cool.

Avoid Engine Overheating

As an important part of a vehicle's cooling system, the car air conditioning compressor helps circulate and dehumidify the air inside the vehicle. If your A/C compressor isn't working, your car won't cool properly, and you may experience problems with your windows fogging up or your engine overheating.

Maximize Vehicle Performance

The air conditioner is just one of the many components of a car's air conditioning system, and the air conditioning compressor is the most critical part of the air conditioning system. When these parts fail, it can have a domino effect on your vehicle, including increased fuel consumption. At the same time, the performance of the air conditioner will decrease significantly.

Reduce Maintenance Costs

A high-quality air conditioning compressor not only keeps your vehicle comfortable and cool, it can also reduce the cost of maintenance or repairs. If your car air conditioner compressor is not of high quality, it can cause major problems such as leaks and clogs. When this happens, repairs can be costly and take time to recover properly.

7 Types of Auto Air Conditioning Compressors

Here are 7 common types of automotive air conditioning compressors and how they differ:

01

Rotary Compressor

Rotary compressors are the most commonly used type in automobiles. They are more efficient than other types and are used in small cars and large trucks. However, rotary compressors are also more expensive than other types.

02

Diaphragm Compressor

Also called a rotary compressor, this type of compressor uses a diaphragm to compress the refrigerant. These compressors are usually installed in the engine compartment because they are not very efficient at compressing air. However, they are more reliable than some other types of compressors and can last up to 100,000 miles before needing replacement.

03

Centrifugal Compressor

Centrifugal compressors are the most common type of automotive air conditioning compressor. They are used in vehicles with high power output and are more efficient than other types of vehicles. This type of compressor is also more durable than other types of compressors.

Auto Air Conditioning Compressor
Scroll Compressor

Scroll compressor is one of the most commonly used automotive air conditioning compressors. Scroll compressors are suitable for low-pressure applications requiring long discharge lines, such as refrigerators or other commercial refrigeration equipment. They use scroll-shaped rotors to compress the refrigerant inside the coils and then expel it into the vehicle. This helps improve energy efficiency because the internal combustion engine (ICE) generates less heat. However, since they have no throttle or variable speed drive (VSD), they can only operate at one speed: full power.

Vane Compressor

Sliding vane compressors are the most efficient type of air conditioning compressor. Vane compressors provide high power and cooling capacity, which is necessary for vehicles that require a lot of power or have extensive cooling requirements. They are also quieter than reciprocating compressors and can be used where sound is an issue, such as in commercial vehicles or racing cars. Vane compressors use fewer moving parts than other types of compressors, which makes them less prone to failure because they don't have delicate parts that can become damaged over time.

Piston Compressor

Piston compressors are used in residential and commercial air conditioning systems. They are cheaper than rotary compressors but are noisier. The main advantage of piston compressors over rotary compressors is their quietness. Unlike rotary devices, which use an electric motor to drive the pump, piston devices use an oil-lubricated piston as the pump. The oil prevents air from getting between the pistons during operation (which can cause loud noises) and keeps the pistons moving smoothly through the stroke cycle without any delay or friction.

Reciprocating Compressor

Reciprocating compressors are the most widely used type of air conditioning compressor in automobiles. They consist of two cylinders that move back and forth to compress the refrigerant, which is then cooled through a condenser and evaporator. Reciprocating compressors are great for cars because they are simple and cheap. Still, they can be more efficient because they are unable to maintain a constant pressure level between the compressor and receiver/dryer elements.

 

Things to Consider When Buying a New Auto Air Conditioning Compressor

Determine the Compressor model

Manufacturers frequently update parts on vehicles so that the parts work efficiently. Therefore, one of the most important aspects that you need to consider is the year, make, and model of the car. In any case where this information cannot be accessed, you can always consult your vehicle manufacturer.

Consult An Expert

There are some vehicles now without air conditioning, especially older vehicles. This doesn't mean that if your car doesn't have air conditioning, it's impossible to install one. What you need to do is consult an expert and he/she can advise you on the parts that are best for your car.

Extra Parts

When installing your air conditioner, you may need additional hardware. Some manufacturers are fully aware of this and can provide you with these parts at a quoted price. This will lower your purchase price compared to other dealers. By shopping online, you also save on shipping costs, and you get good warranty options, too. Usually, people choose the product with the longest warranty.

Right Type of Oil

Needless to say, these compressors use oil, and it's obvious that your compressor needs oil. Always keep in mind the type of oil going into the compressor. It's also important to consider the labor costs of replacing an air conditioner, as well as the cost of the purchase itself.

 

Symptoms of Car Air Conditioning Compressor Failure

There are some warning signs that will present themselves if your AC compressor is starting to go bad. Below are the top 4 symptoms:

Strange Noises

If you switch on your air conditioner and there are a lot of strange noises being generated, then your AC compressor is likely starting to fail. The compressor relies on a sealed bearing and numerous other components to turn. If the internal bearings or components were to get damaged or worn out, then it will make it more difficult for the compressor to operate properly and silently. Strange noises will only be the beginning of the problem. That is why you should take this symptom as an early indicator that you need to get your AC compressor replaced.

Hot Air

If you turn on your air conditioner and you only get hot air blowing out of the vents, this is a clear indicator that your AC compressor is failing. If the refrigerant cannot circulate through the air conditioning system because of a bad compressor, then it is not going to create the cool air that you want. As a result, you will have hot air instead. This might be a gradual process where you will first feel the cool air getting slightly warmer. After a while, the air will get to the point where it is completely hot with no coolness whatsoever.

Leaking Fluid

The AC compressor has its own internal bearings which prevent fluid from leaking while it is pressurizing the refrigerant. However, if these bearings were to become worn out or damaged, then fluid could easily leak through them. You will need to replace the bearings because they cannot be repaired.

The Clutch is Stuck

The AC compressor has its own clutch which is connected to the engine via a pulley and a belt. This allows the compressor to use the engine is power to run. If the clutch were to get stuck or seize entirely, then it would not be able to transfer power from the engine over to the compressor. In most cases, you will not be able to repair the clutch if it has seized like this. Your only option in most cases will be to replace the entire compressor.

 

Mistakes You Should Avoid When It comes to Car A/C Compressors

 

Neglecting Annual Maintenance Procedures

Due to their porosity, all rubber hoses have a Freon leak tolerance of up to 10%. Therefore, it is easy to calculate how much Freon a car air conditioner may lose each year. Every vehicle with air conditioning in the engine compartment is equipped with a data plate indicating the type of Freon and its content in the vehicle's system. For example, if it is 525 grams, the leakage could be as high as 50 grams per year. In other words, if the air conditioner has not been refilled for four years, there may be about 300 grams of refrigerant remaining. This is dangerous because the cooling efficiency decreases and the system is operated at a greater load with less lubricant circulating in it.

Turn on the Air Conditioner in Freezing Conditions in Winter

During air conditioning operation, all interior parts of the air conditioning system are lubricated. This avoids drying out of rubber seals, hoses, etc., thus maintaining the tightness of the system, minimizing refrigerant leakage, and lubricating all internal components of the compressor and preventing corrosion. In winter, the air conditioner should only be turned on in freezing conditions in a warm room, as it cannot work when the outside temperature is below freezing. A warm car room can be a service station, some car wash, a covered parking lot.

Block the Radiator

Installing a fine-grained mesh in front of the radiator-condenser will impair the cooling of the radiator. At the same time, the efficiency of the air conditioning system decreases and the automobile compressor begins to work at high load. Therefore, the resources of the compressor and many components of the air conditioning system are naturally reduced. If the radiator condenser is not cleared of debris, especially after spring, a similar problem can occur when the radiator condenser becomes clogged with lint.

Unprofessional Maintenance

Maintenance of the air conditioning engine is recommended to be carried out by professionals from a verified or recommended professional service station. These professionals have special equipment, including gas stations and gas analyzers used to determine the composition of Freon. During the maintenance process, many irregularities may occur, causing the air conditioner to fail. For example, you've been filled with low-quality Freon, including different types of Freon. Although the mixture as a whole may meet the temperature requirements (boiling point or freezing point) of the same R134a Freon, it may not be compatible with the oil used in the system. As a result, the lubrication of the system will deteriorate significantly, and the car air conditioning compressor will soon fail.

Ultimate Guide

Q: How long should the service life of a car air conditioning compressor be?

A: In theory, a car air conditioning compressor can run for ten years, but in fact, it wears out faster, not because the time has expired, but because there is a problem with the system. If you don't monitor pipes and hoses and clutch and pulley bearings, within three years the system may become unusable.

Q: What are the symptoms of a broken AC compressor?

A: Typical symptoms of a failed air conditioner compressor: A constant buzzing, rumbling sound, or a sound when it is turned on, even when the air conditioner is turned off; No clicking sound when turned on (the solenoid is not working).

Q: Can the air conditioning compressor be repaired?

A: In order to restore operation of your car's air conditioning compressor, not only do you need to eliminate the leak and fill it with new refrigerant, you also need to completely flush the system and sometimes even replace the piston. This is an extremely expensive repair and doesn't always make sense when it would be easier and cheaper to install a new compressor.

Q: How to save the most money on air conditioning compressor repairs?

A: Bring your car in for an A/C diagnostic and get a complete invoice for repairs. Buy all the parts you need from us and you'll save the most money.

Q: Where can I buy the refrigerant I need for my air conditioning compressor?

A: First, refer to our air conditioning system oil chart to find out which refrigerant your system requires. Refrigerant (also known as Freon) can be found at any local brick-and-mortar auto parts store, or you can have a mechanic or air conditioning technician source it during a repair.

Q: How do I know if my car AC compressor is bad?

A: Among the most common signs that your car's AC compressor is starting to fail is that it will start making odd, clunky noises. This is typically a sign that the compressor is about to give out for good. So, if you notice any weird noises coming from your AC unit, it's time to take it in for repair.

Q: What is the average life of an auto AC compressor?

A: Your AC compressor and refrigerant should last about 12-15 years.

Q: Can I drive my car with a bad AC compressor?

A: It's never a good idea to drive with a broken compressor. Doing so can result in expensive repairs that are otherwise avoidable.

Q: Can a car air conditioning compressor be repaired?

A: If your compressor shows signs of failure, good service, lubrication, and air conditioning recharging can resolve any issues and prevent future failures. But if it does fail, then you will need to replace it. This is not a case of simply removing the unit and installing a new one like other car parts.

Q: Can I unplug my AC compressor and still drive?

A: You can drive with a locked-up compressor if you disconnect the wire to the AC clutch. If a pulley doesn't rotate, disconnect the driving belt from the compressor and tension roller, but only if it doesn't connect a water pump and other parts.

Q: Why doesn't my car's air conditioner blow cold air?

A: Your vehicle's air conditioner not working could be caused by a faulty air conditioner compressor or a Freon leak. While these are the most obvious reasons why your car's air conditioner isn't working, it could also be something as simple as a broken belt or a dirty cabin air filter.

Q: Can I replace AC compressor myself?

A: Typically, replacing a compressor should be done by a professional, but you can perform this task at home if you are competent working with your hands. Doing the job yourself can also save you a decent amount of money.

Q: How much does it cost to replace a car air conditioning compressor?

A: The cost to replace a vehicle's air conditioning compressor depends on the type and location of the vehicle, as parts and labor costs vary. On average, it costs about $1,100 to replace an air conditioner compressor, with labor costs ranging from $160 to $200 and parts costing $650 to $840.

Q: Why is my car's air conditioner cooling so slowly?

A: A coolant leak inside the air conditioning unit, an open hot coolant valve, a damaged air compressor, electrical problems with the climate control system, a clogged air filter, or loose flaps can all cause your car's air conditioner to cool slowly.

Q: Does car AC get colder when driving?

A: Your car air conditioning works much better when you're actually driving because the faster the engine turns, the faster the AC compressor runs, which lets the system cool more effectively. Don't waste time and gas by letting your car run before you go.

Q: How long does it take for a car air conditioner to get cold?

A: On average, your car's air conditioner takes three to five minutes to cool down. However, some cars may take longer depending on the model and air conditioning compressor. A car air conditioning system functions similarly to a house or office air conditioning system.
