Power is power, 600Watts of power is 60ĒWatts of power wherever you are.
I accept that I may be a bit dense but I simply cannot see how you can have any machine thatís 600% efficient as you are suggesting. Itís simply not possible as there is no machine on the planet thatís 100% efficient, let alone 600% You cannot get more energy output than you input. Itís a basic law of physics.
If it was possible the entire planets energy needs would disappear. Country ďAĒ produces 1million kilo watts of power and exports it to Country ďBĒ who, using a 600% efficient machine convert that 1M to 6M. They then export it to country ďCĒ who do the same, so 6M becomes 36M, the next country do the same and you get 216M. Next country x6 gives you 1296 million Kw so after a few countries you have billions of Kw of energy available.
An air conditioner is basically a fridge it draws heat from the air inside the motorhome and TRANSFERS it to the outside air. Thatís why it has a fan and you can feel hot air being ejected by the fan and the fridge on your motor home needs a current of air across the back to remove that heat (a MH fridge doesnít have a compressor though, it relies on a convection current so is less efficient) The energy to do all of that has to come from somewhere and thatís the compressor thatís inside the air on unit. That compressor needs an energy source to operate, either electrically to turn a motor or mechanically from the vehicle engine.
To quote an old saying. ďYou get nowt for owtĒ
Its not the destination that matters.
It's who you share the journey with (even if itís in a caravan!) I am very fortunate to have Mrs Plodd to share mine with
