Question about DIY air conditioner with ice chest.

Okay so I made a DIY air conditioner out of a ice chest and a fan from a air handler. I have it sitting on the ice chest blowing into it and the ice bottles inside.I have about 3 gallons worth of ice bottles in there and the air still does not blow cool..Why is that? Is the fan blowing to much? I don't understand why its not blowing cool. Ive tried everything even put salt in the water and on the ice to make it cooler.Thats what the fan looks like.

It does blow through the ice chest. I have 3 holes cut out in the front with pvc pipe so i can direct the air flow.

Adjust the blower speed to the lowest speed. BTW, I have never seen anyone try this before, Good Luck.

Way too much airflow is my guess. I think most people use box fan. That thing looks like its rated for several thousand cfm.

Edit: having the ice in bottles is insulating the ice. Freeze the ice in bottles and then cut away the plastic before placing them in.

Edit 2: Do you have access to free ice or something? I'm pretty sure you're much better off with a portable air conditioner. Or using the fan as an evaporative cooler.

You're just kidding yourself with that contraption, it will never supply even the equivalent of a 1/4 ton of cooling.

I bought one of those type of fans about 10 years ago. they call it Ice cool fan. around $70, same concept as yours. It did not perform well, so you only see that type of fans on the market for about 2 years. Just not enough cooling power. I used it as a regular fan for a few years. never bother to add ice in there after a few days, does not work anyway.

I have one set up almost identically with the frame, only sitting on the outlet. We use it to evacuate air from crawl spaces, etc. Very inefficient, IMO. Air is drawn in too close to the outlet, so you are not moving much air from an extended perimeter. I sat it in front of the shop with the doors open and could not feel any air movement in the shop because it was drawing air within inches of the outlet. Placed my large round fan there, and it drew much better.'

The "air conditioner" set ups with ice are cute, but I doubt they would be very effective, especially with such a forceful fan.

What some people fail to realize is air conditioners do NOT create cold. They only move heat from point A to point B. They just move the inside heat from inside to outside. What you are trying to do an old fashioned ice box did but that used a block of ice that was almost a quarter of the size of the very well insulated icebox. Insulate your house as well as an icebox and fill one fourth of it with a solid block of ice it might work... till the ice started melting. If your too young to relate to an ice box think of a picnic cooler and how much ice you must put into it..

A ton of cooling is the equivalent of 2000 lbs of ice, or 12000 BTU's. Your 24lbs of ice would equal 144 BTU's

Thats also how freezers work. They move heat out of the the water into the kitchen. So if you're freezer is inside your house, really you're just waisting a lot electricity to change the temperature of the water and then let the water reabsorb that same heat outside the freezer.

You need more ice surface. Use ice cubes. Not in bottles or bags, just bare ice cubes in the chest.
