How to cool the car off with out running it

[oil pan 4]

This weekend is going to be something like 104°F.
My wife wants a car port. We don't have one yet plus 104 is still pretty warm.
So I went to lows and found an 8,000btu/hr frigid air brand air conditioner that said "dent" on the front. Price was $240. Yes It had a dent.
I figured I would try to see how far I could talk them down.
I got it for $140, I didn't even plan on buying an air conditioner when I went there today.
I am going to replace my 3 or 4 year old 5,000btu A/C for the guest room, sell it for $75.
Until my mom visits I'm going to use it in the car.

So I folded down the back seat put the air conditioner in the trunk so the front was blowing into the back seat area and packed a towel around the edges and plugged it in. Leave the trunk open for heat rejection.

I will add pictures soon.

It cools off the car great. Cant be using more than 10 cents worth of power.





Unplug, toss the cord in the trunk, close the trunk, close up the seat and you don't even know its there.
If you are in a humid area the condensation might be a problem. It normally very dry here.

I'd say you got ripped off...but at least its 8000btu. I didn't pay much more for my portable 8000btu, and I only paid 50 for a 5000 and 70 for another 5000btu. That was a few years ago, mind you...

Oh, hey...they're meant to drip off out the back, afaik. You might have a "leak" spring up all of a sudden...

We had about 20% humidity today. Any extra water will get burned off by the condenser coils.
I wasn't going to pay $240 for a new one.
Some one I work with wants to buy my 3 or 4 year old window unit for $75 next pay day.
So total the new window unit will only cost $65.
I try to use them for 2 to 4 years then sell them and replace them with a brand new scratch/dent unit.
Instead of running them till they die, plus after a few years they lose efficiency and don't cool as well.
Last summer i was using all window units, I have replaced all window units with high efficiency inverter split heatpump units except in 1 room that is used for storage and guests.
Now the window unit will hardly get used.
I sold the other 2 window units as soon as it started to warm up a few months back.
The splits cost about $2,400. I got tired of noisy inefficient window units that barely cool the house.

Nice mod! I am curious roughly how long it takes to cool down the car?

I ran it for an hour, that was plenty long enough. The compressor even cycled off.
I think it really only needs more like a half hour.
