That sir, is incorrect. Ask anyone that has owned a boat for many years. Normally the pump is run to clear the bilge & is not used for a while. I suggest you search on "why boats sink at the dock". The cheap bilge pumps crap out - hopefully not when you need them in an emergency situation.

Nice idea but i submit that implementing will be akin to urinating off the high side (of the boat - not compressor).

it seems like he'd rather spend nickel and dime to buy 2 bags of ice on every summer day that he'll drive his $300 car @ 85mph for 2 hours on a veggie than spend a little more to fix the system properly

I'm thinking coffee would be so much better and could even be endured the first couple of miles in the summer.

The quote is from Albert Einstein

Yes, I have one of these things that someone gave to me. I was amazed when I saw them go for over $200 at the swap meet.

Now, how big are the units? Would they fit under the hood? I'm just thinking about leaving the setup all stock except for the compressor.

I know I probably will not do anything, but you never know! My house uses the R410A.

How would the AH @ 18,000 BTU translate to say something like "uses 16 amps when operating"?

Ok, I have the solution.

Bucket of Ice/water with the bilge pump. Run a long hose from the pump through the seat back and bottom and then back into the ice water. You could even run a longer hose through both seats.


Then in the winter, you could run some coolant through it. 180 degree seats OOOOOWWWW HOTTTTTT!

so pretty much you want an over complicated swamp cooler

Did anyone on here ever see America's Worst Driver (I think thats what it was called, it was dumb didn't last too long). They had a car with a huge clear box tank on the roof. There were hoses placed in the upper corners of the tank that ran down into the car above the driver and and passenger. Any sudden movment, turn, stop would force the water down the tube onto the occupants. If you make sure your doors are sealed tightly you could have a mini wading pool. :D

also if this system is going to work what about the price of ice and the expense it will be

$2 for a bag of ice can get pricey after a while

As long as we are free thinking, why not use a venturi system. This is what small airplanes use (ACM - air cooling machine). They all use bleed air from the engines, hence, not much cool air while on the ground. This, however, could possibly be resolved by using an electric motor in a car. The cheap route: weld together 2 metal funnels at the skinny ends and then mount an electric motor at one end to force ambient air thru at the front end. If you can achieve enough pressure, the air exiting the opposite end will be super cooled from the low pressure in the middle of the venturi. You may not, however, be able to achieve enough presure inside the venturi with the electric motor, so another possibility is an extra turbo from a 300D, which could be mounted aft of the regular turbo with piped-in ambient air to the squirrel cage.

Mine is EXACTLY like that except it is a gold color. It has the same sticker on it.

I would sell it for $200 and then you problems would be solved.

new swamp cooler
 

New swamp coolers are available:

The principle here is when the water evaporates from the cooler, it takes heat from the air, cooling it. I'm originally from southern La., and these things never worked well with the humidity so high and the air so full of water vapor at the start.

There's all sorts of other schemes. I once thought of using liquid nitrogen. (it can be had for $0.10/L, about a quart) and just spraying it into a heater core. Or just spray it out into the car, as long as there's small amounts of it. You'll die if you try to live on straight nitrogen.

And seriously, I've seen a working a/c for automobile installation that used air as the working fluid. It was not in a car at the time. It compressed air, heating it, cooled the air with a "radiator"/fan set up, then used a "expansion valve" (just a pin hole) to expand the air. It put out very cold air, a fog like out of a freezer. It worked well as a demo. I think it would have to have a steady supply of clean air to be reliable.

No practical air conditioning probably did him in.:rolleyes:

Took 3 hrs to plumb and wire the pump. Top 2 lines into exp valve are the IN and OUT to the evap. Cut fittings off the copper tubes and ran new lines thru vents to passenger floor to pump and cooler.

95 degree ambient today..
using a small cooler for first test and about 2 trays ice water I got 75 degrees at the vent for about 20 minutes.

With a standard size cooler plumbed in and bigger blocks I should be able keep cool for 2 to 3 hrs.

I will not need to buy ice.....someone has invented this thing called a deep freeze, its amazing. Just put water in it and it freezes it for free. A 5 gallon bucket block of ice fits perfect inside the cooler. I'm hoping it will lengthen the cooling period. Everything is Temporary....

My $300 airport commuter car (odometer stopped at 330k) is back to blowing cold air again. Thanks for all the input and ideas.
