Automotive AC Machines
As any mechanic knows, the ability to offer a comprehensive service to customers,
being able to offer repairs and care for all aspects of a motor vehicle maintenance program is key to being able to retain customers.
Air Conditioning is more or less standard across all models these days, and while in the past, AC maintenance was a highly skilled and niche market, it is now an essential side of the business and key to any workshop’s continued success.
In order to ensure that refrigerant is recovered properly from a car’s air conditioning system during servicing, a workshop must use an automotive AC machine.
These devices prevent the release through venting of CFC gases. EPA guidelines require that when a car is being serviced, the Freon,
or CFC12 that is used as the coolant should be collected and recycled in order that it is not released into the environment where it can potentially damage the ozone layer.
The refrigerant used in most motor vehicle air conditioning systems is based on chlorofluorocarbons, which have been linked with causing damage to the ozone layer, and as such, the control of these substances is of particular concern to the environmental protection agency.
Whenever a car air conditioning system undergoes maintenance, proper care must be taken to protect the environment from the release of CFCs, and this is best done by using automotive AC Machines.
By reusing Freon gas rather than allowing it to be vented into the atmosphere, the environment is protected. However, when the refrigerant is collected from a car’s air conditioning it can be contaminated with water,
oil and any of the other liquids that are used in cars. By using automotive AC machines, it is possible to process the refrigerant and remove any of the other fluids from it,
allowing it to be reused, either in the same system as it has been drained from, or alternatively, in another car altogether.
There are a whole range of different refrigerant recovery machines on the market to suit all types of workshop, from small operations through to large commercial garages that deal with many different types of car, and need to be able to offer a complete service to clients.
Choosing the right automotive AC machines for your needs can be a daunting task, and too many people simply opt for the cheapest model available, rather than making an informed decision about the best product for their needs.
EPA requirements aside, the most important factor when choosing the correct automotive AC machine for your business, is the capacity of the machine to deal with the range of vehicles that you currently work on.
You need to choose a machine that can connect easily with all the different types of car that your workshop deals with, and which has enough capacity to recover and treat the refrigerant left in the system to remove any impurities.
Basic automotive AC machines such as the Pro Set Oiless Portable Recovery Recycle Unit are flexible enough to reprocess coolant from a fairly wide range of sources, remove any contaminating oils and other liquids, and release the Freon in perfect condition for reuse.
There are other machines in a similar price bracket that are reliable enough for every day use, and yet still compact enough not to require a vast amount of space in your workshop.
Automotive AC Machines such as the Inficon Vortex refrigerant recovery machine are ideally suited to occasional use, and are very compact.
If offering AC repairs and servicing is key to your business, then having the right tools for the job is essential. Getting it right at the beginning when you choose an AC coolant recovery machine often means choosing a model from the Cool Tech range.
These robust and highly regarded specialist tools are at the centre of any serious AC shop, and thanks to their efficiency and great value for money, will pay for themselves over and over again.
Automotive Air Conditioners
It’s August, the car is jammed with kids and luggage, and you’re finally on your way to the cottage. Suddenly you realize that your car’s air conditioning system is on the fritz, and your family vacation really starts to heat up.
Automotive air conditioning systems were first introduced in 1940 to address customer demands for relief from unbearable heat.
These systems use refrigerant to cool the air and remove the heat from the car’s passenger compartment. Air conditioning also cleans the air that enters the car, and removes excess moisture as it dehumidifies the air.
There are three basic components to any automotive air conditioner system:
1. Compressor–Considered the heart of the air conditioning system, the compressor transfers and compresses refrigerant gas to let the heat out of the car.
2. Condenser–removes heat from the refrigerant and cools down the high-pressure gasses.
3. Evaporator–Acts as the heater core of the air conditioning system. The evaporator removes the heat from inside the car. The refrigerant then condenses the air and transforms it into water.
Cars manufactured in 1995 or later have been equipped with R-134A air conditioning system. These ozone-friendly units do not contain CFCs, are nontoxic and nonflammable.
Prior to 1995, automotive air conditioners came with R-12 refrigerant, most commonly Freon. During that time, a car owner experiencing air conditioner problems needed only to visit a local retailer to purchase a recharge kit.
With a can of Freon and basic knowledge, the average driver could easily repair his or her own air conditioning system.
When studies confirmed that R-12 systems were contributing to the damaged ozone layer, many countries including the United States banned their manufacture.
The most common complaint about automotive air conditioners, particularly R-134 systems, is the odor that permeates from the A/C vents. Mechanics and car manufacturers have concluded that accumulated bacteria and fungus in the evaporator core likely cause the odor.
Because the air conditioning system is loaded with moisture, it attracts microbes. The solution offered by automakers is to make the blower motor effective in drying out the evaporator after the A/C system is turned off. General Motors introduced this breakthrough, called Electronic Evaporator Dryer.
This solution might offer relief to some car owners, but not to all. Installing this system can cost hundred of dollars. As a result, many car owners have resorted to finding alternative methods of fighting the odor.
Using antibacterial chemicals such as Lysol can be an effective short-term solution. Keeping a can of Lysol handy can go along way for your odorous air problem.
Just spay the Lysol inside the car, and in the air intake once a week, for temporary relief from the problem. Another way to help eliminate the odor is to shut off the A/C unit at least one mile before reaching your destination.
This will allow enough time for the evaporator to dry out, essentially doing away with the moisture and microbes that cause odor. This can be the easiest and least expensive method in combating the issue.
Caring For Your A/C System
* To keep working efficiently, your automotive air conditioner must be recharged from time to time, depending on how often it is are used. Consult your mechanic or your owner’s manual for information about system recharges.
* Call your mechanic if you see water leaking from the A/C system’s condenser, as this can affect the refrigerant. Have the system repaired before refilling it.
* Replacing the filter once every three months will also help to maintain the performance of your automotive air conditioning system. This is where dust builds up when the A/C system is running.
* Setting the gauge at one specific temperature will also help it perform well. If you constantly switch from one temperature to another, your system will have trouble adjusting accordingly.
Automotive air conditioners can be a driver’s best friend, whether you’re traveling across town or from coast to coast. Keep your A/C unit well maintained, and keep your cool on the road.
