Assuming this worked, how do I make this? I assume its a air conditioning.. I see
copper pipes, presumably circulating water via pipe, why i dont know

an ice box... a fan... this has to be an air conditioner right? so how does it work, how would you make one? shouldnt there be a pump

Just buy a window AC unit. You can get a 5k BTU one for $175, it will cool WAY better, it will be far less of a pain in the ass to use, and it's far more energy efficient than constantly freezing large amounts of water in your freezer.

I guarantee you that it uses more electricity to freeze a bunch of ice in your freezer and convert that into cold air in a room than it does to just run a small AC unit to do the same amount of cooling.

>> No.2549772

>>2549348
Refrigerator compressors are not made to do that kind of cooling. They are sized to keep a small volume of air cold which inside a highly insulated box. If you do what you show in your diagram, it's either not going to amount to any real cooling or it's going to kill the compressor. Or both. A window AC unit would use less power to cool better and would last much longer doing it.

A small window AC unit will cost you at most maybe $1.50 in electricity per day. Compare that to how much it costs to run the fan, run the pump, drive to the store and back, and purchase X number of bags of ice per day (you'll be likely to go through more than 1 bag a day)

>> No.2550496

>>2550483
>and purchase X number of bags of ice per day (you'll be likely to go through more than 1 bag a day)
That's easy. One ton of ice (latent heat of fusion) is 288k BTU or 12k BTU/hr over a 24 h period. That makes one pound of ice worth 6 BTU/hr. A window unit is probably in the neighborhood of 3k-10k BTU/hr.

>presumably circulating water
The styrofoam cooler is filled with ice and has a pump in it. The pump circulates water through the ice to cool it before it goes to the copper loop attached the fan, where air blows over the copper and gets cooled by heat transfer before heading back to the ice to do it all again.

>>2549083
>Where I live, the cold water out of the tap is cool enough year-round to make this work
No, it isn't. "Cold" water out of the tap will warm up much faster than ice, meaning you'll need to change the water out a lot more often.

>>2549115

Actually, if you're going to disregard their cost then there's no good reason to do this instead of getting a window AC. If they are the same price to you, why would you choose the most inefficient method? Or are you just fuckin retarded?

By time you waste your money and time on the parts for this meme cooler you could've just gotten a window unit and been way more comfortable for about the same amount of electricity. Not only that, but this fucking monstrosity takes up a ton of space in the room instead of the wimdow AND you have to keep taking this shit all apart so you can dump the warm water out and refill it with ice.

Yes, but that doesn't mean it doesn't work.
I literally used cold water for this back when I had a third-floor apartment ... one summer day was unbearably hot, and the A/C window unit wasn't doing enough, so I filled the bathtub with cold water and ran a fan in the bathroom doorway. It cooled the apartment down.
>"Cold" water out of the tap will warm up much faster than ice
That's the whole point of the contraption. Water is taking heat out of the air. If the water is warming up, that means the air is cooling down.
As the water approaches the ambient air temperature, drain the tub and fill it again.
Simple as.

>> No.2552353

>>2552307
No need to drain the tub, just put a cutting board or something in it under the tap so the water flows across the whole bottom and let it sit with a moderate flow. The tub will be chilled and the pipes leading to it will be constantly refreshed with cool water and lower the temperature of the walls gradually.

>> No.2552378

>>2552353
You'll also get loads of condensation off the copper coil that the fan will then blow everywhere.

Excess solar energy. Freeze a large amount of water at solar peak and use it with this method for the solar downtime. Cuts energy use from the grid or batteries enormously. I have a large house and some 20 kWh excess solar even on a bad day up to 40 kWh on a good, so I'm tempted to fix some kind of ice making machine and submerge a copper air intake pipe in the ice water bath permanently, this should permanently reduce the air intake temperature and thus the energy needed to cool it to a target temperature while the ice lasts

Large office buildings do this already. They get preferable rates overnight and make the ice. It's a very efficient way to time shift the load.

>> No.2552987

>>2552976
Yeah i saw there are some large commercially available units to do it too even so makes sense, the vast majority of my energy usage is cooling, too so i can't see much of a downside in doing this, i
I am thinking some kind of high wattage icemaker outside that i will rig to hass and autodump on full state to a large insulated container, radiant pipe loops in the container, insulated run from there to the intake on the household ac units, when they draw air in they will thus draw chilled air through the precooling apparatus.

It works if you're looking for something a bit better than just a fan. That being said, just get something purpose-built. It'll be more efficient and actually help during hot days. These also don't work so well when it's humid, so good luck in those climates.

>single hose unit

you know those actually suck the air from inside to cool the condenser coils and blow the hot air outside. you are basically cooling the air to just have it blown outside to keep the condenser cool so it doesnt overjheat

always get the 2 hose model that pulls outside air to cool the condenser and blows it right back outside so the evaporator can actually cool the room without the rooms air being used to cool the condenser.

>> No.2556741

>>2552307
I don't think you grasp the concept correctly. Ice will work better than cold water because it delivers lower temp water to the fan for cooling AND it can exchange more heat than cold tap water.

>>2552353
You're too stupid to insult. Once the water has exchanged all the heat it can it will stop cooling and you will have a tub of warm water. It's not a perpetual energy device. You will need to drain and refill the cooler.

>>2552378
Which is the exact opposite of what you want. You need to REMOVE moisture from the air to feel cooler. Unfortunately this device has no setup for the collection of drain water so it either re-evaporates back into the room or leaks everywhere.

>>2552971
Just go buy a fucking bag of ice for $4.

>>2552976
No, they don't.

>>2552987
For all that work you could simply pipe the tube through your existing fridge/freezer.

>>2554439
Using room air to cool the condenser improves efficiency and reduces electrical use without impacting the room temp dramatically.
Cool room air - easier to condense - lower pressures on compressor - compressor draws fewer amps. Outside air is the worst idea.
