160-Watts

My AC is currently broken so I had the idea to put a large blower fan (for ventilating a house while painting or something) in the passenger floor to cool me off. It seems to draw A LOT of power. It's currently hooked up to a 160watt inverter. I can really only use it for an extended time on the lowest setting, haven't tried the medium but on the high setting it'll trip the inverter to turn off cause it can cause the voltage readings to dip below 12 if I'm playing music at a high enough volume to hear over the blower and my sub hits too hard. I for certain can't use my headlights and the blower at the same time.

My question is, will this possibly impact my fuel economy the same as if I were just running the AC?
1) 160-Watts is a little over 2/10ths of a horsepower.
2) The belt-driven A/C compressor will pull 2-3-horsepower.
3) If you can keep your head and neck ventilated, you've got a shot at comfort.
4) If it's very humid, you'll never really be comfortable, without the dehumidification an A/C offers.
5) Any 12-VDC blower, out of any automobile, on 'high'-speed, would provide enough airflow to cool you, if it's going to happen at all. Losing the inefficiency of the inverter might make up the distance with the alternator output.

A split-type AC would be a more obvious choice

Seriously, there were some folks in my country adapting residential split AC units on vehicles, mostly trucks and motorhomes. There was even a guy who fitted a spit AC into an Opel Omega, with the condenser right in front of the radiator and the evaporative unit on the roof right behind the rear seat area.

Yeah, I'd use the blower in the car if my control panel wasn't busted and stuck on heat lol people want like $450 for a non-busted used one so I went with the inverter and blower in the floor for now till I can find a cheaper replacement for the ac controls
