dear supplier,i want to ask you these radiators of evaporators are separated from evaporator or inside of it? if it is inside where is the compressor?is that inside of evaporator or outside of it?does it have separated battery or we should use of the automobile battery?i ask all these because i am looking for one A/C to use it inside an automobile at the summer.You know that when we use A/C WHICH IS FOR THE CAR,AT THE TIME OF USING IT uses more petrol and it reduses the speed of the car when driving.if to be one seperated A/C which we dont use of the automobile battery AND it works by itself with its own battery and it would be great.tks/Naser
