When we operare a 24Volts system on 12 Volts,the performance is same ,can any one brief how it can be attained.
The vechile Operating voltage is 12 volts where as system is operatin at 24Votls.
Another fine example of a badly described problem.
I think that the OP has an Air Conditioning unit which requires a 24volt supply.
He wants to run this air conditioner in his car which has a 12v electrical system.
Of course I may be completely wrong in my understanding.
Do you get 24V AC aircon units then? (I know nothing about aircon - apart from mechanically powered ones in cars, and big single or three phase mains ones).
Certainly if you do, then it seems a good bet - it's certainly an obscure enough power requirement.
Use a DC-DC converter to up the voltage? Mind you, an air-con system would draw umpteen Amps at 24V so the converter would gobble at least 2 x umpteen Amps. I think a fair bit of the air-con's duty would be cooling the converter .
I have an Air Conditioning Unit in my caravan that operates on 240 vac normally, but can be operated on 12 vdc whilst mobile. I've never used it on 12 vdc except to try it once to check it worked. On 12 vdc it will only operate on minimal setting - seems to just operate ventilation fan drawing air across refrigerant fins. I've always been a bit concerned that RAM air would damage the fan.
