How to Select the Right Size A/C Vacuum Pump

Wed, 11 Nov 2009 14:19:33 +0000

A A/C vacuum pump has several uses for the auto air conditioning mechanic and automotive shop. The main purpose of a vacuum pump is to remove air and moisture from your automobile air conditioning system. Moisture is a serious threat to your car’s air conditioning system. Moisture will move through the refrigerant line as fine mist and crystallize wherever it expands. Also, when moisture mixes with refrigerants it will become extremely corrosive. You won’t notice this damage until it’s too late. A vacuum pump removes moisture by creating a vacuum in the a

Air Conditioning Condensers: Giving You a Cool Driving Experience

Wed, 11 Nov 2009 14:19:33 +0000

Driving in your faithful Mercury during the summer months should prove to be a cool experience - that is if you're AC condenser is working properly. However, if you do feel that amidst turning on your air-conditioner to its full capacity you still feel sweaty and hot, then you may want to check your AC condenser.

The Mercury AC condenser radiates heat of the refrigerant, which at most times is a Freon gas, passed to it by the AC compressor. The AC condenser cools the refrigerant and turns it to a liquid form. The engine fan would usually aid in the cooling of the refrigerant, albeit an additional condenser fan would still be needed. The liquid refrigerant would still be warm but it would not be as hot as the gas in the compressor. An expansion valve would then advance to transform the liquid refrigerant into a cold, gaseous form, so as to once again absorb the warm air inside your automobile.

Thinking about how it works the Mercury AC condenser is one of the vital and essential parts needed to keep your air-conditioner working for your Mercury. It could, in a nutshell, be compared to your vehicle's radiator because it works out the same function. The radiator keeps the water circulating throughout the engine to cool, and on the other hand, it is your Mercury AC condenser that keeps the refrigerant flowing through your car's air conditioning system to cool.

Changing a Mercury AC condenser which has already gone through the usual wear-and-tear would surely ensure you a cool ride, even during those humid summer days.

Convert your automotive air conditioner from R-12 to R-134 Refrigerant.

Wed, 11 Nov 2009 14:19:33 +0000

If you have an older car it may have R12 refrigerant in the air conditioner system. You can still buy R12, but it is very expensive. If you are ready to convert your system to R134, here is a brief explanation of the procedure with a few insider tips to help you. To begin you will need a conversion kit with all the necessary materials. It will include: 2 new adapter fittings, 2 -3 cans of R-134, and a hose with adapter. Once you have all the materials, you can begin the process. The first thing you have to do is have the R12 recovered with a refrigerant recovery machine. (It is illegal to just open the valve and let it out in the air.) Now that the air conditioning system has no pressure, it is time to install the new valve kit. At this point some people freeze up (no pun intended) because they are afraid of mixing up the adapters on the high and low pressure ends. Don’t worry, they are different sizes. The bigger one goes on the low pressure side of the system and the refrigerant hose will only connect to the low side valve. It is pretty hard to mess this up. Now that the adapter valves are connected, it is time to start the car and put the air conditioner on high. Turn the blower fan to its highest setting as well and open the windows. Grab a can of R134 and hook up the hose and T valve that came with your kit. With the hose hooked up to the can begin to twist the T valve until it punctures the can. Then open the valve to let some freon out and purge the air in the line. Turn the can upside down and hook it up to the low side adapter valve. Now slowly open the valve and let the Freon flow into the system. At this point the compressor will begin to cycle on and off. Don’t panic, this is normal. Keep adding Freon until the system begins to cool. You can feel the low pressure line begin to get cool and condensation will accumulate on it. (Do not grab the high pressure line. It can burn you.) You probably will not need all 3 cans and be careful not to overfill the system. If the air conditioner is still not cooling after the second can, something is wrong. You may have a leak in the system or some other difficulty. Do not be tempted to keep pumping Freon in the lines. If the low side line is cold and dripping with moisture you are done. If you have a air conditioning manifold gauge set, the low side should have a pressure of 40 – 50 psi. Good luck and stay cool!

Question : I SUSPECT my 1985 Nissan 130Y may have an electrical problem.

After an extended run, the air conditioning system cuts off and cooling does not resume until it has been switched off for at least 15 minutes. I have consulted at least three air-con specialists but none have been able to solve the problem.

Answer : THE air conditioner of a car works on the principle of a refrigerator, removing heat from the air within the passenger cabin, and discharging the heat into the atmosphere.

A typical air conditioning system consists of a compressor situated between two radiator coils. The compressor pressurizes a gas (freon, a family of gases that contain hydrogen, carbon, chlorine and fluorine), transforming it from a gaseous to a liquid state.

The liquid is forced through an orifice into a cooling coil (located in the passenger compartment), where it evaporates. The evaporating fluid absorbs heat from the atmosphere (cabin). The gas is then transported out of the passenger compartment to another cooling coil located in the engine compartment where excess heat is discharged to the atmosphere.

The cycle is repeated and the gas is re-compressed. There are many reasons why an air conditioner can stop working, and one of the most common is that the compressor fails to engage (compress).

A safety switch located along the air-conditioning lines switches the compressor off should the system pressure rise or fall below pre-set safety levels. Although these switches are relatively reliable, they are liable to occasional failure, but replacements are relatively cheap.

Alternatively, the switch could be switching the compressor off because the system pressure has risen beyond the upper safe working limit. This is either because the system has been overfilled with gas or the electrical cooling fan has failed, resulting in excessive high system temperatures and consequently
exces- sive pressures.

On the other hand, if there is a leak in the system and system pressure falls below a lower safe limit, the compressor must be prevented from running in order to prevent damage to compressor components. An air-conditioning system specialist would be able to measure if system pressure is causing your problem.

The last possible cause is the failure of the thermostat or the "anti-frost switch" (if available). This prevents excessive cooling and icing of the cooling coil.

A build-up of moisture around the cooling coil reduces airflow through the coil resulting in reduced airflow, hence reduced cooling efficiency.

Thermostats and anti-frost switches are relative cheap components to replace, and a specialist should be able to determine if they have failed.

Automotive air conditioner basic troubleshooting tips.

Wed, 11 Nov 2009 14:19:33 +0000

Automotive air conditioner basic troubleshooting tips.

It is summer time and very hot outside. Especially in your car and especially if you are sitting in traffic. Here are few troubleshooting tips you can try yourself before running to the dealership or auto repair shop to fix that pesky air conditioner. If your automotive air conditioner isn’t working quite right, here are a few ideas to begin. First of all start with the control panel on your dashboard. Most automobiles have an A/C button that actually turns the compressor on and allows cold air to be circulated. You might have accidentally hit the recirculation button instead of the A/C button. (Don’t laugh, I had a friend that spent a week in a hot car and all he needed to do was press the right button.) The second thing to check is the actual function of the controls. Do they move at all? Are they loose and jiggle around? The big question is “do they feel different from the last time your air conditioner worked?” This could tell if the controls are messed up and need replacing. Your air conditioner system may be fine but the controls could be frozen or broken. If your controls seem to be functioning, let’s move to the blower fan. Turn on your car and start you’re air conditioner as you normally would. Then turn your blower to its highest setting. Can you here your fan blowing? If you can hear it, does it sound weak or whinning. This could signal that your blower motor is malfunctioning or needs to be replaced. If it doesn’t work at all, check the fuse for the blower motor. The fuse for your blower motor should be located in the fuse box under the dash.

Most automobiles have the fuses clearly labeled. First take out the blower fan fuse with the removal tool provided in the fuse box. A blown fuse should be easy to identify. However if you are unsure, replace it with a similar rated fuse and try your blower again. If that fuse blows you may have a bad blower motor or a short in the circuit. In this case, you will need an authorized mechanic to fix it.

If the blower fan is working properly and you can only get cold air out of the defroster vents, you may have vacuum-system supply line problem. To check for this, look for a small black plastic tube going from the engine area through the dash. It is usually right by the refrigerant lines. Check this tube and see if it has holes or is not connected. If you have one, you can hook up a A/C vacuum pump to your air conditioning system and pull a vacuum on it. If it won't hold a vacuum, then there is a leak in it.

To locate a leak, there are several different types of refrigerant leak detectors or sniffer leak detectors on the market. These handy tools can help you locate where in the A/C system refrigerant is leaking.

If all of these little tips are not helping and you’re A/C doesn’t blow cold air no matter how many switches you turn on or off, you will probably need an certified mechanic. Good luck and stay cool!

How to Select the Right Size A/C Vacuum Pump

Wed, 11 Nov 2009 14:19:33 +0000

A A/C vacuum pump has several uses for the auto air conditioning mechanic and automotive shop. The main purpose is to remove air and moisture from your automobile air conditioning system. Moisture is a serious threat to your car’s air conditioning system. Moisture will move through the refrigerant line as fine mist and crystallize wherever it expands. Also, when moisture mixes with refrigerants it will become extremely corrosive. You won’t notice this damage until it’s too late. A vacuum pump removes moisture by creating a vacuum in the air conditioning system. The low pressure will boil off the moisture at very low temperatures. This will vaporize the water and vent it out through the system. Now the next issue is what is the best type and size of vacuum pump to use. First, there are 2 types you will come across. The cheapest is a venturi type that runs from your shop air compressor. A Venturi type are popular with the home mechanic crowd since they are cheap and easy to use. However, they are limited by the fact that they it is very hard to boil off much moisture with one of these types. They just will not pull a good a vacuum as you need. The best and most common types that are found in a professional auto shop is a good electric model.( Click here to see a Robinair Vacuum Pump.) Every professional air conditioner mechanic and auto shop have at least one. You now have to decide what make and model to purchase or rent. Most air conditioning vacuum pumps have a CFM rating on the box. This indicates how much air volume it can remove from the system. The more air the pump can move, the quicker it will achieve the proper vacuum. There is also two stage and single stage pumps. Also, the two stage pumps are quicker and more efficient, but a single stage will get the job done. This chart below is handy reference to help you choose the right size for your needs.

How to Use a Air Conditioning Vacuum Pump on Your Car

Wed, 11 Nov 2009 14:19:33 +0000

A vacuum pump is a piece of equipment that will allow you to pull a vacuum on your car's a/c system. They fairly simple and inexpensive to operate. First, turn off your car's air conditioner and shut the engine down. You don't hook the vacuum pump directly to the A/C system. You to first hook up a refrigerant gauge manifold set to the low pressure port on the system. (Generally, this is the blue hose that is attached to the gauges.) On your gauge set there is a port in the middle. This is where you connect the vacuum pump. Using a gauge manifold set allows to shut down the vacuum pump without losing the vacuum you have just created. If you just hooked the A/C vacuum pump straight to your air conditioner, you would lose the vacuum as soon as you

Refrigerant Leak Detector! Finding Leaks in your Air Conditioner

Wed, 11 Nov 2009 14:19:33 +0000

As summer approaches, it is time to start thinking about our car’s air conditioning system and if it is working properly. One of the most common problems with an A/C system is refrigerant leaks and locating them. Finding the source of the leak can be a tedious and time consuming. The leaking Freon could come literally anywhere in the system from tubing to a accumulator to a tiny pressure switch gone bad. The EPA has made it much more stringent rules in dealing with refrigerant leaks. The days of topping off the air conditioner with a few cans of R12 are long over. Now even small leaks must found and corrected. Here comes technology to the rescue. There are several methods air conditioning repair shops employ to locate and fix refrigerant leaks. Each method has its pros and cons and their use depends on the situation. The three most commonly used are a electronic refrigerant leak detector, ultraviolet dye leak detection kit, and

Robinair AC machines have come along way from just recovering refrigerant

Automotive AC Machines

Wed, 11 Nov 2009 14:19:33 +0000

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 refri

Robinair 15600 AC Vacuum Pump

Wed, 11 Nov 2009 14:19:33 +0000

The name Robinair is synonymous with quality and respect in the automotive air conditioning industry. They produce a full line of air conditioning service products and are used by professional mechanics worldwide. One of their best known products in their top of line high quality vacuum pumps is the Robinair 15600. This model is the choice of professional air conditioning mechanics and auto shops worldwide.

Robinair 15600 is the industry standard.

The most common air conditioning vacuum pump is the Robinair 15600. This versatile vacuum pump is a 6 cfm, 2 stage vacuum pump that is most often found in the automotive service shops. For the professional automotive shop, the 6 cfm is minimum size vacuum pump you need. This size can handle vehicle air conditioning systems ranging from a car all the way to buses and RVs. The Robinair 15600 has the cfm to removc moisture and air from most vehicle air conditioning systems. This unit has the power reach a 600 micron vacuum in under 60 minutes on most air conditioning systems. A weaker unit takes more than twice that amount of time. Also, the latest A/C systems are built to much tighter specifications and getting a good solid vacuum has never been more important. The reason is the modern systems are far less tolerant to contaminants and moisture build up and this can cause long term damage. If moisture builds up in the lines, it can crystallize at expansion points in the air conditioning system. This is why pulling a good vacuum is critical. A good solid vacuum in the system will evaporate the moisture and prevent “freeze up”. Moisture causes many other problems. High moisture levels combined with refrigerants is very corrosive to air conditioning systems. You will not notice the effects of corrosion until its done some serious damage.

The Robinair 15600 is a good investment

It may be tempting to use an inexpensive Venturi type vacuum pump. This type a vacuum pump works off of shop air to produce a vacuum on an air conditioning system. They are cheap and relatively easy to use. However, they will not pull a proper vacuum and they leave damaging moisture behind. The Robinair 15600 vacuum pump is a 2 stage model that runs off of 110 volts. The 2 stage rotary design and high cfm rating on the 15600 insure you will get the required 600 microns of vacuum. (It can achieve this under 60 minutes saving you time as well.) Venturi type vacuum pumps are really made for the home garage mechanic and professional air conditioning service techs do not use them. A good 2 stage vacuum pump will pay for itself over time and produce far better results.

Robinair produces vacuum pumps with lower cfm ratings and they may be fine for your particular application. All of the Robinair vacuum pumps are 2 stage and built to the industry’s highest standards. But if your operating a automotive service shop or maintain a varied fleet of cars and trucks, the Robinair 15600 should have you covered for most air conditioning systems.

Refrigerant Recovery Systems and EPA Compliance

Wed, 11 Nov 2009 14:19:33 +0000

Back in the 1980s, it became apparent that the most popular refrigerants used in automobile air conditioning systems could do a great deal of damage to the environment if they were released into the atmosphere, and consequently, refrigerant recovery systems were needed to collect any CFCs. CFCs or chlorofluorocarbons have been proven to damage atmospheric Ozone. The Ozone layer protects the world from the harmful ultra violet rays from the sun, and if it was damaged people around the world would suffer a higher risk of contracting various skin cancers from the sun.

The EPA (Environmental Protection Agency) put in place a number of guidelines and regulations to minimize the amount of CFCs that were unnecessarily released into the atmosphere, and required that whenever repairs are carried out to an automobile air conditioning system, the refrigerant is collected by using a refrigerant recovery system, and then it can be recycled or properly disposed of in order to minimize any environmental impact that it has.

Under section 608 of the CAA, the EPA requires that all possible measures be taken to prevent the venting of CFCs when car air-conditioning is being worked on. The act, which was introduced in 1992, sets out a number of penalties that can be applied to anyone who knowingly allows for CFCs to be released into the atmosphere. These penalties include large fines after conviction, and heavy censure.

In order to meet the EPA regulations and ensure that a minimum of 80% of refrigerant is recovered during repairs to an air conditioning system, a good quality refrigerant recovery system is absolutely essential as part of your workshop set up.

Because the damage done by CFCs to the ozone layer is practically irreparable, and extremely severe, preventing their release into the environment is absolutely essential, and it is because of their potency that the EPA regulations are so strenuously applied. If a person or business is found to have broken EPA guideline 608, they can face fines of up to $25,000 per violation.

Although the huge fines for operating without a refrigerant recovery system ought to be enough to ensure that everyone in the industry invests in keeping in line with the regulations, simple environmental responsibility should also be taken into account.

Choosing the right kind of refrigerant recovery system for your business is essential. You need to ensure that the equipment has enough capacity to handle whatever jobs come your way, and yet fits in with your acquisition budget.

Refrigerant recovery

A/C Charging Scale

Wed, 11 Nov 2009 14:19:33 +0000

When repairing and refilling an air conditioning system, getting the exact amount of coolant in the system right is essential if you want it to work properly. This is where A/C charging scales come into their own. These handy tools work in conjunction with your AC coolant recycling equipment to refill the AC system properly and get it completely correct.

The more accuracy that you can work with when adding the coolant to an AC system, the better it will work, and the less likely it is for anything to go seriously wrong with it in the near future. A/C charging scales are designed to provide a pre determined amount of coolant such as Freon into the system in order to get the system filled up as efficiently as possible.

An A/C charging scale is a tool that is designed to help you to get the right amount of coolant prepared for loading the AC. In general, an air conditioning system will be rated to contain a specific amount of refrigerant in order to work correctly. This is done by weight rather than volume, as this can vary greatly dependent on temperature.

When the refrigerant has been purified correctly, it can be weighed using an A/C charging scale to gauge the correct amount. Then it can be injected back into the air conditioning at the correct pressure to make it work correctly.

There are a number of important EPA guidelines to consider whenever you deal with CFC coolants such as Freon. These chemicals are very volatile, and have been linked with doing serious damage to the ozone layer. This important part of the atmosphere is the main protection for the planet from ultra violet radiation from the sun. The ozone layer protects our lives, and since the 1980s, when concerns about the effect of CFCs on the ozone layer first became important, governments aro

The Robinair 34788 A/C Machine is the first machine available for refrigerant recovery that is fully compliant with the new SAE J2788 requirements that came into force in 2006, and will soon be mandatory. This means that for any business which is involved in refrigerant recovery from automotive air conditioning systems, the Robinair 34788 A/C Machine is an essential purchase required to stay in line with the latest EPA regulations.

The SAE J2788 regulations regarding the handling of AC refrigerants came into force for the first time in late 2006, as a guideline recommendation, and will become mandatory later this year. The regulations state that there is a requirement for all the CFC refrigerants to be collected when recharging an automotive AC system to prevent the leaking of the chemicals into the atmosphere.

It has been known for more than 20 years that the chlorofluorocarbons like Freon that are used as coolants and refrigerants in air conditioning systems are damaging to the environment. CFCs react with atmospheric ozone, causing it to be broken down and disperse. The ozone layer is an area of the atmosphere around 30 miles above the surface of the earth which protects the planet from the worst effects of the ultra violet radiation from the sun.

When CFC gasses like Freon are allowed to escape into the atmosphere, they damage the ozone layer, and reduce its ability to protect the planet from ultra violet radiation, which can cause skin cancers.

Since the 1990s, the EPA has introduced a number of recommendations and regulations that are designed to protect the environment from the release of CFCs. One of the most important areas that are governed by the regulations is the motor vehicle air conditioning servicing industry. When air conditioning is serviced, the CFC chemicals in the refrigerant need to be cleaned and recycled rather than simply released into the environment. Large fines are handed down to anyone who breaks the regulations, and these can run to tens of thousands of dollars for severe infringements.

With this in mind, it has become incumbent upon any auto workshops that deal with MVAC processes to keep up to date with the latest refrigerant recovery tools in order to ensure that they stay in line with the EPA requirements for refrigerant recycling, and air conditioning repair work.

Over the last few years, the requirements for keeping in line with the latest EPA guidelines have become ever more stringent, and with this in mind, Robinair, the leading company in producing refrigerant recovery machines has released the Robinair 34788 A/C Machine. This is the only AC machine currently available that is in full compliance with the new SAE J2788 regulations, meaning that for anyone looking to retool their workshop in line with the law, it is the only choice available.

Thankfully, the Robinair 34788 A/C Machine has all the features that you would expect from one of the top manufacturers, is easy to use, and carries out its work in a reliable and timely fashion. The main thrust of the new regulations is to tighten the restrictions

Antifreeze Recycling Equipment

Wed, 11 Nov 2009 14:19:33 +0000

Modern antifreeze recycling equipment can turn old worn out coolant into “like new” condition using a process of chemicals and filtration. In today’s environmentally conscious society, recycling and the conservation of resources is foremost on most people’s minds. Antifreeze is one of those chemicals that all modern automobiles need to run efficiently and well. With all the focus on gasoline and motor oil, the ethylene glycol in automotive antifreezes is easy to overlook. However, your car’s radiator should be flushed and new antifreeze put in at least every 30,000 miles. This makes for a lot of antifreeze that needs to be disposed of properly. There is another solution, instead of replacing your current antifreeze with a new coolant, your old antifreeze can be recycled and used again and again. Nearly all antifreeze is a combination of ethylene glycol and an additive package. Ethylene glycol will not wear out but the additives will become old and useless. This is why antifreeze needs to be replaced. The ethylene glycol, which is the petroleum based component of antifreeze, is still good and useable. It’s the additives and the gunk that collects in the your car’s coolant that render it unusable.
