Car Air Conditioning Facts

Although it was initially a luxury, air conditioning is currently a common element in most vehicles. The best thing is to leave the servicing of your car air conditioning systems to professionals. However, you can have the most enjoyment from the system if you know a few things about how it functions and the specific malfunctions to look out for.

Car Air Conditioning Facts

In general, there are numerous options in automotive air conditioning such that it might be overwhelming. Since the financial investment needed can be substantial, making the right choice is a vital personal and business decision.

Australia’s extreme temperatures make air-conditioning an essential thing, especially when it comes to construction and mining since it has a huge impact on:

· Productivity and performance
· Dehydration, heat exhaustion and safety
· Emotional stability & decision making
· Breathable air quality, allergens and respiration
· Fatigue and alertness

Each of these factors has an economic effect on the company, employees and their clients. Needless to say the safety and general well-being of people.

Regardless of your choice of rooftop or bunk air-conditioning units, you should ensure that:

· Air-conditioned spaces need to be frequently ventilated.
· Professional installation and service is important
· Try to sustain an average humidity of around 50% – 60%.
· Keep room or bunk temperature around 21º – 25º C.

Studies prove that the human body tends to feel comfortable at 21-25 degrees Celsius, with 50% relative humidity and an adequate flow of clean air. The working efficiency of human beings is maximum in comfort conditions. That means that they can work with much vigour, productivity and clarity.

A reliable air conditioner helps in circulating filtered air within the vehicle, truck or construction equipment. The air is relatively free from bacteria, microorganisms, smoke, dust and dirt particles etc. Because of this, it allows a healthier environment inside, and the overall well-being of the person is secured.

There’s less noise when the windows of the air-conditioned regions are closed. Generally, less noise maintains peace and allows soothing sleep. And this is something that can be crucial.

Why Should You Have Your Car Air Conditioner Serviced Routinely?

This is one of the most commonly asked questions.

For starters, the Automotive air conditioner system is distributed over a huge part of the vehicle. You got the condenser right up front while the evaporator is within the cabin. All the other functioning parts along the way are all joined with rubber hoses and generally sealed with rubber o-rings.

The environment is usually harsh since it has to deal with extreme temperature changes, engine vibrations, corrosion from the elements and much more. The reality of the situation is that there is nothing like a perfect moving seal and, quite frankly, the compressor seal does the hardest job.

The compressor is typically driven off the engine and the only thing that prevents the gas from escaping is the seal surrounding the shaft to the compressor’s body. This seal requires lubrication and it only comes from the oil inside the system and the oil is supplied to the seal by the gas.
Bearing this in mind, it is only safe to say that after a few driving years, the system will have used a fraction of the gas delivering the lubricant to the seal. As a general rule, the less lubricant and gas in the system, then the less lubrication of essential parts and the likelihood of premature malfunction of these components. Generally speaking, up to 10% of the system’s charge is utilised in this way annually, and a further 10% of the remaining charge every year after that.

Why Does My Refrigerator Never Require Service?

Have you been wondering why your refrigerator never needs service?
This is primarily because a refrigerator compressor doesn’t have any exposed seals or o-rings. It is typically sealed inside a steel container as it holds the full charge of oil and gas. Once charging is complete, the pipes are usually crimped and soldered while every other joint is also soldered together.

Generally, this allows an entirely airtight seal on that system. Another important thing you should know is the difference when it comes to system power. Once you turn on your refrigerator, you do not expect it to be cold for several hours, the automotive system is often expected to ensure cold air is coming out of its vents before driving to the corner of your street. Since the automotive system is functioning much harder, it requires more maintenance.

You Might Have to Consider Recharging Your System If Your Vehicle Doesn’t Feel Cold Enough

Perhaps your vehicle doesn’t feel as cold as before? If so, then your system might require servicing since the refrigerant gas that’s used to run the system tends to deplete over time. On average, many vehicles lose up to 15% yearly. This leakage often occurs when the system isn’t used in the winter months, which leads to the drying out of the small “O” ring seals and causing a slow deterioration in system performance.

In case this continues, the system will eventually not be able to function at all. Many issues of this sort could be resolved quite easily by conducting a leak check of your system and a complete refill of the air conditioning refrigerant. Sometimes, this is known as a re-gas.

Air Conditioning vs. Climate Control: What Is The Difference?

Essentially, air conditioning is a cooler, as it cools down the air to a preset temperature. On the other hand, climate control is a system that uses your heater together with the cooler to provide you with a steady even temperature that could be set to your comfort. Typically, these systems control fan speed along with vent direction based on sunlight conditions and temperature set. However, there is one thing you should know is that – in case you do not have climate control, then you can control your air conditioning system’s temperature manually, by allowing a bit of warm air from your heater. What’s more, this is an excellent option for defogging your vehicle in winter, since the air conditioner can dehumidify the air.

What Could Go Wrong With Your Air Conditioning System?

Most customers don’t use their air conditioning system in the winter months. Sadly, this might lead to drying out of the internal seals and ultimately cause leaks. It would really help to use your air conditioning all year round for demisting their windows. In most cases, air conditioning systems will function even if the heater is on, and when it comes to summer, that air conditioning unit hasn’t suffered the common issue of seals drying out.

By turning air conditioning systems off during the winter months, it leaves condensation within the pipework. Together with heat from the engine, this allows a good breeding ground for mould spores and bacteria. Apart from the unpleasant smells, it can lead to allergic reactions and sore throats. Furthermore, windows often mist up in the winter months when the filter is blocked since the warm air stream can’t circulate appropriately.

So, how would you identify a faulty system? Some of the warning signs include:

· Strange odours from vents
· Inadequate cooling from vents
· A rhythmic clicking sound from beneath the hood with the defroster or air conditioner on
· Noisy drive belts, blower motor or compressor
· Water on the passenger compartment’s floor
· Windows that cannot defog when applying the defroster
· An electric cooling fan that tends to cycle on and off quickly

Run Your Air Conditioner Throughout the Year to Help Maintain the System

If you run your air conditioning during the winter months, it will not only keep the system well lubricated but also leak-tight. This is because the refrigerant comes with the oil that lubricates the system and the compressor. It also keeps the hoses and seals moist, which prevents them from drying out and cracking, causing leaks.

Why Disinfect?

Does your air conditioner make you sick? Perhaps it has a funny smell whenever you turn it on? During your Air Conditioner’s operation, water usually condenses on the evaporator within your dashboard and is discharged below the car. It can be noticed as clear water dripping beneath the vehicle when the system is being operated. Typically, this moist dark environment is ideal for allowing the growth of mould and other spoors. It is often the cause of bad odours whenever the system is switched on. In case you’re travelling with a passenger with a cold, you might get the germs that are cold incubating in that moist environment. Getting the system disinfected routinely helps get rid of these nasties.

Strange Noises Need to be Attended Immediately

In case your air conditioning system begins to make noises that you haven’t heard before, it would be best to have a professional vehicle air conditioning check on it. Some noises might be early signs of a compressor failure.

Generally, the compressor is the costliest part of the system and if your compressor bearings fail or if the compressor seizes up, it means that other parts might get contaminated. In such as case, a flush of the system will be required, as well as replacing the compressor and certain components, which might be quite expensive.
What Is Retrofitting?

You might have come across this term, but you have no idea what it means. The Ozone protection plan was formulated Back in the mid-nineties and led to Ozone-depleting gases becoming a controlled gas. Since one of those gases is R12 Refrigerant, it was phased out and the entire importation and production of the Gas was halted. R134a, a new Ozone Friendly Gas, was meant to replace the R12. However, it had slightly different properties, since it was not particularly compatible with the lubricant utilised on the R12 systems. Therefore, the system needs to be modified to operate on the new Gas, fittings, filters, expansion valve in certain situations and the oil. Furthermore, the new gas works at around 10% higher working pressure which can cause some issues on an older system.

Why Would You Consider an Air Conditioning Diagnostic Service?

When you have an issue with your Air Conditioning, this particular service is made to locate the fault. Is that fault because of low gas levels, faulty components, electrical fault or a blockage somewhere? Because any one of these faults might be the cause of your trouble, it would be prudent to inspect and correctly diagnose the fault. Think of it as visiting the doctor and getting a blood test and physical to identify the problem.
