Technologically speaking, does this work?

>So what you're saying is I need more ice?
Yes, like 40 kilograms of it. Per hour. 4 20 lbs bags. Each is $5 I bet.
$20/hour.
I think window air conditioner is cheaper in long run. It will pay for itself within a week.
And yeah, I assumed 0C, not whatever -20C they are keeping it, so you may need little bit less.
This.

Yes, but a few frozen bottles of water behind it would have been more effective if set to low.

>latent heat of fusion, 334000 joule/K-kg
Yes, I assumed 0C water.
>as well as the latent heat of vaporization, 2230000 joule/K-kg.
It is important only in dry climate. But in dry climate you can 30C without AC no problem. And if it is 35C, you can swamp cooler.

yes

t. thermodynamics and entropy expert

Oh, and I forgot that AC usually doesn't run full retard, but rather with 50% duty cycle.
So, 20-ish kilo of ice.
Only if refrigerant leaks.
Window and mobile AC are brazed at factory, and they check them with sniffer. They are sealed units, just like fridge you have, so they don't leak (usually). There are a lot 30+ year window units that are still working.
Also, keep in mind they use similar AC on factory to make ice.

Mini splits and central air is different story. They are installed by HVAC specialist. If HVAC specialist had made shit braze (for central air) or shit flare (for mini split), and didn't pressure test with vacuum and nitrogen (like all of them do. Most of them only vacuum lines for couple of minutes in best case), it will leak.
Or thirdworld install, like I did, where you don't use vacuum pump, but release freon to remove air from lines...

>Also, keep in mind they use similar AC on factory to make ice.
I meant they use similar technology but beefed up.

>I assumed 0C water
But your answer said 40kg 0C ice, not 40kg 0C water.

I had a brain fart. I thought about ice, but I meant water.

You're right. Transporting a literal metric ton of ice to your commune hut from some iceberg in the arctic ocean every day is clearly the only solution to global warming.

Am I taking to AOC by any chance?

Just get one of these if you're thinking of that.

>Hydro Chill Technology
don't post schlock here

Literally the same thing can be done by hanging wet towels with a fan blowing across it, except cheaper, more cooling, and less portable

It would be more efficient to put the ice behind the fan's rear intake. The ice in front the lower temperature air (even in spite of it being slightly lower than ambient 'cause you know air in motion is cooler) isn't as efficient as from behind the intake because the air in motion blowing from the fan causes the ice to melt faster than the rear position.

IT'S FUCKING SCIENCE, YOU MORONS.

better to do something like this

>put pipes in holes
>cut hole in lid
>put fan in lid
>put ice in bucket

put them inside a closed bottle if the surrounding is humid

Fuck is this bullshit

It is called a "ghetto" solution. It does solve the issue, just uses no complex methods.

Just wear shorts and point the fan at your calves. Let blood circulation do the rest.

mixes the air and the ice. If its done right there's a grill inside letting air get to the bottom of the ice and a catch tray to drain meltwater.

I have two of them because the central air in my house can't keep up with all the crap I have running in my room. They run for about 8 hours on low with about 20 oz of water in them and keep the room about 20 degrees cooler for about 10 watts of power draw on low. It's a better option than putting an additional portable window unit in and hogging up more power and space.

I built one of these a few years ago, its total bullshit and didn't work whatsoever.

Next time use frozen water bottles. Not just bags of ice or ice water.

retard
9th grade physics

Yes, it would work, but would introduce a lot of humidity (ice is solid water, and humidity is invisible water, duh). For better results try using special "dry" ice.

The ice would be way below 0c, probably -20

I used frozen gallons of water, same kind of container that you usually see milk stored in.

The main issue will be increased levels of humidity

wear swim shorts and put ice in your pockets. I do it nearly every day and it works great.

>the future (2019)
>there is still no new technology to keep you cool
Fucking yikes.

So you greatly reduced the surface area available to cool air and got shit results?

Just put a fan on your window blowing in at night.

Yeah blowing warm air into a hot house is totally going to work well

It would be even more efficient to eat the ice cubes.

Why does this work? Is it simply due to the blood vessels in the feet? Or is there a nervous reason too?

>how does this work

its like asking how polar vortex works

for being Jow Forums you guys suck at tech
thats literally the most efficient way of doing it

Attached: obcdrnacrja11.jpg (1024x576, 110K)

can i have a quick rundown of how that works?

Blowing a warm load into your hot arse is totally going to work well.

>heres a thing
*the thing

Freezing the water in your freezer generates more heat than what the ice cools, but it's not like you care about your whole apartment. So OP's pic works for a while if you make it blow in your direction.

Cold drinks and ice make your body heat up to counter the cold, it would be the opposite of effective.

Heat is vented from the body through hands, feet and head. Stick one of those in cold war and you will cool down fast.

exactly, this is Jow Forums, not /sci/

thats literally how an AIO cooler works

only that you need to put some ice ont he bucket every 5 to 6 hours (room temp above25)

I'm guessing cold water is circulating through the copper pipe and the fan is blowing on the pipes cooling the air a bit

Yes, obviously.
>air is directed over ice
>heat transfers from air to ice

Looks similar to typical liquid cooling.
Coolant cycles through, being refrigerated and pumped through copper pipes. Guessing the cooler has a reservoir and a pump in it and is then just filled with ice, since I can't see any other pipes. Could have a peltier device or something else stupid on the other side I guess. Really not sure what the gray cable is. I thought it was just power for the fan but then running it inside the cooler would be kind of retarded. Also to go to all that effort and then not drill and seal proper holes in the cooler is unforgivable. Looks like it's open 3~ cm on the far side and would surely destroy it's potential efficiency.

>Am I taking to AOC by any chance?
Ayy carramba

look up "swamp cooler" apparently people in deserts use an alternative AC tech that ADDS humidity instead of removing it. sounds crazy to a swamp dweller like me.

Ice cubes are hugely overrated actually, can't absorb a lot of heat energy and therefore don't provide a noteworthy cooling improvement over a liquid that's cool to begin with (i.e. cold tap water). Unless you're already at swampy humidity (in which case AC is the only solution) the most efficient methods to cool down are wearing a damp t-shirt with a fan going (careful not to get sick, don't point the fan directly at you) and/or sticking your feet into a bowl of cold water.

yeah basicly this but its more efficient if done properly
(close the bucket and drive the copper pipe inside completely)

>2019
>Entropy still running the show

>ice evaporates
>humidity increases
If you have 29c and 45% humidity and you start using that useless piece of shit, bravo, now its still 29c but the humidity is over 50% and it feels even hotter.

Whatever happened to thermoacoustic refrigerators?
Around 20 years ago in TV they said it was going to revolutionize cooling.

yes but not the way you'd think and most likely that fan generate more heat than what those ice cubes would be able to cool

go back to

Entropy always wins.

>For better results try using special "dry" ice

inb4 somebody suffocates in a hot room because they replaced all the oxygen with co2.

JUST USE LIQUID NITROGEN TO COOL THE ROOM BRO.

What's the quietest desk fan?

just add more ice and fans

You forgot to consider the friction of the fan producing more heat, a simple cooper heatsink would work much better than a fan to transer the heat to the ice
This design solves this But it would be better to use a box sealed with an exposed heatsink instead of using a fan

Or even better, put ice inside a big sealed heatsink, i mean a car radiator with ice inside would cool a room perfectly, if you replace the ice once melted and the room is properly heat insulated, no fan would be needed.

How could I, the brainlet, learn basics of physics related to cooling and air flow from the internet? I'm well after HS and I didn't take physics and I already forgot the basics I had in middle school.

Is it doable on a basic level?

Would this work?, i would walk in the street with a fan tied to my head.

Why do you have to be this way?

i finished high school and after that i just started reading on my own i hated the way teachers use education just for the kid to be brainwashed on being dependant of the said goverment

I attached a 120mm fan to a baseball cap once, blowing in my face. it worked pretty well but dries your eyes out.

brown fat is only in the feet and collar bone, so these are the spots that will most effectively warm or cool the blood
