Ever been on a family road trip? If you are anything like us, then amongst the eye spy and various petrol/snack stops, a healthy debate is inevitable. Arguing anything from politics to the big bang, the best way to cook any given meal and of course to the epic chicken and egg scenario, our family has covered it all. Well… all except one.. does air conditioning use more petrol?
The big Air Conditioning Use Debate
This has to have been one of the more heated debates. As we all know, air conditioning use needs power, why? Well for the technical explanation, it uses energy to compress the cooling liquid. This process requires a big heavy compressor. In the home, the air conditioning condenser is installed outside with interconnecting pipe work joined to an indoor evaporator. Normally a wall mount and if you are especially fancy, a Daikin one (the Rolex of the Air Con world).
So what about on those long distance journeys in the heat…20 miles from the nearest petrol station and the fuel light flashing vigorously because dad didn’t want to stop at the last service station?
Considered a bit of a myth by some, it is, in fact, true (Mum was right). We do use up more fuel by keeping cool. So air conditioning use burns petrol! Why? Well, In a car, the compressor is linked to an electric clutch which engages the process. This process requires more energy than if the car was simply driving. There is a 2% increase in the use of fuel when you turn on the air conditioning.
So now is the bigger question, did we keep cool and knock out on the side of the road or did we listen to mum and wind down the windows to conserve our last litre of fuel? Well….I am writing this whilst waiting for the AA to recover us. Thanks, Dad.
