General info and advantages of air conditioning

 Because the UK has a temperate climate many people have assumed that air-conditioning in their car would be a rarely used luxury that was not worth paying for. Now that we have experienced a relatively warm summer (and 2013 being the warmest summer in the UK for over 10 years) the benefits of air-conditioning are gradually being generally accepted particularly as our climate is relatively damp with moist (and thus uncomfortable) air. Moreover the additional benefits that are not immediately obvious are now being appreciated by those fortunate to have a good system operating in their car. As about 80% of all new cars are now fitted with AC as standard since about 2008 almost all of us now have the ability to use this facility even if we only ever buy secondhand cars. Just be aware though that if you buy a two year old car that the AC will not be working as well as it was when it was new – most cars would be needing an AC service by three or four years old.
What are these benefits?
• The ability to reduce the in-car temperature to a comfortable level on exceedingly hot days, without having a seventy mile an hour gale buffeting you and being unable to hear the radio or your passengers because of the wind-noise.
• If you have youngish children you will quickly appreciate the extra quiet in the back – aircon seems to almost magically remove the bad temper from most children.
• As aircon also conditions the air, the ability to remove the moisture from the air coming into the car on really muggy days and to achieve a comfortable atmosphere within the car, perhaps in conjunction with the heater control – the AC button will control the Relative Humidity and the heater if needed will control the temperature leaving you free to enjoy the warmth without being stuffy.
• The ability to be able to see through the windscreen and all the other glass clearly without a film of mist. The safety aspect of aircon is often overlooked but is extremely important, particularly to the people-carriers which are so popular now. Using the AC button to direct the air to the screen the moisture on the glass will be evaporated very rapidly, long before a screen-heater has had a chance to warm up and will continue this advantage around the side glasses and on to the rear screen. For best effect use the AC button, perhaps in conjunction with the heater in winter and on the fresh air setting (not recirculation). AC is usually extremely good at de-misting and this safety aspect of good all round visibility, even when picking up a crowd of wet noisy kids in winter, is one of AC’s strong points. It has to be admitted that very occasionally the climate can be so very damp on odd days that even with the AC working effectively the demisting function can work only slowly but this is very much in the minority – for most days the AC will clear the screen like magic.
• The cleaner, fresher air with low Relative Humidity will enhance driver awareness and help prevent drowsiness making your journeys and those of your loved ones safer over long distances as drivers are better able to remain fresh and alert.
• Being caught in a long traffic jam on a hot day can be purgatory with all the exhaust fumes coming straight into your open windows, particularly if you are dressed for business – wet under the arms and hot under the collar – probably the time when you most wished that you had bought a car with aircon. This is when AC proves it is one of the nicest affordable luxuries.
• All the air coming into a car with aircon passes through a heat-exchanger, which as it is very cold, quickly becomes dripping with condensation, which collects and drains out under the car. Air entering this heat exchanger will contain dust and pollen grains, but by the time the air has passed through this heat-exchanger (called the evaporator) the vast majority of these pollutants will have been filtered out, trapped by the condensate and dripped back onto the road. It is estimated that approximately 80% of all dust and pollen is trapped in this way on each pass through the evaporator – this helps us all but is a source of particular relief to Hay Fever sufferers or Asthmatics, particularly children. Most modern cars now also include a filter to remove most pollen and dust, although frequently called a Pollen Filter it should really be called a Cabin Filter as it is very useful in both summer when pollen is rife and in the rest of the year to remove road dirt and other pollutants such as brake and tyre dust. The AC will simply assist the removal of these pollutants.
• By allowing all car windows to remain closed, even on the hottest days, the aerodynamics of the car remain at optimum, keeping fuel consumption low and exterior noise to a minimum, increasing safety to the driver and passengers. There is a page devoted to the fuel consumption aspect of AC – please read this as there are plenty of urban myths on the use of AC. Tell any lie frequently enough and many people will start to believe it.
Any disadvantages? A couple of minor ones – Opera singers or even actors can find that the dry air can degrade their voice. 


Air Conditioning Re-Gas - R134A
Your Air-Conditioning doesn’t just provide in-car comfort during the hot summer months; it can also be used in winter to demist your windscreen. Air-con systems create dry warm air rather than the normal humid air from outside which can clear your windscreen much more quickly than your regular blowers.If the Air Conditioning system isn’t working properly moist air won’t be able to demist the windscreen, affecting visibility.

Around 10% of air-conditioning gas will be lost from the air-con system every year, that's why most car manufacturers recommend that the air-con system is recharged with new gas every 2 years
