Car Air Conditioning & Engine Performance

How does a car’s air conditioning affects engine performance

I’ve previously mentioned in my other blogs on engine performance in particular with the alternator & AC. The AC when in operation typically robs about 10% of our car’s horse power.

There’s a video on YouTube Channel “engineering explained”, illustrating this point further. Here is his findings - With the AC turned on, the car uses more energy to reach top speed. ( View the video here https://youtu.be/ue6DsRncyfI )

Windows down vs AC

We approach this problem with our unique KoolTec AC Concept. The oil in the AC compressor lubricates, remove dirt & reduces friction and if the reduction of friction is further enhanced, the AC compressor would need to work less hard to provide the cooling efficiency.

What we do for you is to remove 100% of the old compressor oil & inject a new superior quality oil package with quantity of oil & refrigerant specified by the car’s manufacturer and this completed with no parts removed. This special compressor oil package reduces friction in the compressor drastically thus giving back horse power to the engine.

The History of Air Conditioning

The History of Air Conditioners & How This Changed The World

With temperatures continuing to rise across the world & summers becoming more & more unbearable with each passing year, there’s no better time than now to take a look at the evolution of cooling through the years & how man grew to be dependent on his little invention.

Did you know that man’s attempts to keep his homes cooler than the outside temperature have been going on since ancient times? However, it was only in 1902 that Willis Havilland Carrier invented the first modern air conditioner.

There are a few historical moments to note which influenced the development of automotive air conditioning (MAC) -
- 1987 Montreal Protocol phased out of ozone depleting substances
- 1994 R12 refrigerant banned in all automotive AC & replaced with R134a
- 1997 Kyoto Protocol signed to protect earth’s climate reducing green house gases
- 2013 R134a green house gases compulsory replacement with R1234yf in all new car models
