Fun fact: the entire reason refrigeration and cooling capacities are measured in tons is because it’s based on the amount of energy required to melt one ton of ice.

to melt or to freeze?

When it comes to refrigeration, it's two sides of the same coin. While one end cools, the other side heats. In home ACs, the heating end happens to be outside (where it heats up the outside air while the inside portion cools the inside air). And heat pumps are just ACs but running in reverse. Refrigeration is basically moving heat in the opposite direction of entropy.
So basically, an AC unit can melt or freeze ice with the same amount of energy depending on which end you point at the ice/water.

But the term came from the amount of energy required to freeze a ton of ice because that was the purpose Willis Carrier invented the technology for. Back then they'd use it to create ice out of nearby fresh water for cities instead of shipping it in from far off glaciers or frozen lakes. The ice was how you kept house or restaurant-scale things cool.
Plus you're incorrect on the heat pumps. They generally have higher heating capacity than cooling because the inefficiency in the system creates some waste heat.

How can cooling capacity be measured in melting ice? Heat capacity I get but cooling?

Better than nothing. I had to do this in Scotland a few years ago when it was hotter than balls there and even the Scots were like: ‘Yeah, air conditioning would be nice right about now.’

My AC broke when I was living in the valley several years ago. I mcguyvered a set up with one of those Styrofoam coolers, a series of frozen water bottles, a fan like yours there and then a 90 degree dryer vent. Cut holes in the top for the fan and the vent, fan blew down into the cooler and the dryer vent came out the other side. It worked pretty well as a personal cooling unit. Just had to have at least two sets of water bottles to keep things going.

u/Not_RonaldRegan Aug 28 '26
Yeah we actually have central AC but it’s currently broken. Until Monday when the replacement part comes. And then maybe fully fixed by Wednesday. Maybe. Until then just sleeping in a room at 90 degrees Fahrenheit.

Grew up in the San Gabriel Valley.

Sort of got used to it… sort of.

I like your set up. I made this homedepot bucket one 10 years ago and still use it today. If it’s for like a small bedroom it cools it down by a good 5-8F. I usually fill up Liter bottles with water and freeze it, and you can reuse it/save on ice.

$5 a day in ice x 30 = $150 for very localized cooling. It's probably more efficient to use ac.

Before moving to a place with central AC I had a portable LG AC unit with the vent hose that goes out the windows from offer up for $100. I gave it to my parents and it's been running for 7 years. Cools down a large room quick and uses like $20 in electricity a month.

No Lisa, it won't overload the motor! The motor runs 12 hours a day for 30 years. It's not going to care about running more hours for a few days. It will, however, make your food warm.

Drop the ice into a trashcan, drill a doorknob sized hole near the top of the can (somewhere above the water line when it eventually melts), set the fan on top of the trashcan blowing inward (kinda sealing the top of can with the fan).
The can will collect the cold air from the ice and the fan will blow the cold air out the hole you drilled.
We saved a server room at Dell in the early 00’s when the cooling went out in the building. We bought up all the ice at all the local gas stations and grocery stores, filled large plastic trashcans with ice and placed box fans on top. We had like 20 trashcans in that server room.

Only thing I can think I’d try is putting the ice block behind the fan so the fan is pulling cold air; at the moment I can’t help but wonder if it’s just blowing hot air across the ice and making it melt faster. Ice block looks cool, though!

u/GreenDaynger Aug 28 '26
That's how I did it when I was in a similar circumstance. Only problem I can think of is any moisture getting pulled through can mess up the motor.

u/whateversclevers Aug 28 '26
You don’t want to pull moisture through the fan and motor. Better to keep it in front.

u/droppedketchuppacket Aug 28 '26
blowing hot air across the ice melting it would mean that the hot air is cooling down, which is exactly what OP is hoping for. it's thermodynamics, man.

u/StereoMushroom Aug 29 '26
The melt water is going to be close to freezing temperature, so shouldn't be too much evaporation going on. If OP drains the water before it gets up to room temperature I'd think effect on humidity should be pretty small.

The best way to cool yourself is to lower your core temp. One of the easiest ways to do that is through the anus. Get to work.

If you have metal colander place them on top of the ice. The ice will cool down the colander and diffuse the air to create more surface area.

Put it in a cooler, crush the ice, run a tube that’s fed by a fan through the ice in the cooler, you can also put some water in the cooler to better transfer the temp, no mess no clean, it’s more efficient at delivering targeted cooling

u/Petridishmocktail Aug 28 '26
I know the picture looks funny, but this is exactly the way an old fashioned ice boxes used to work. Someone would deliver a large block of ice and stick it in the top of the machine and a fan would blow on it keeping the food cold before refrigerators became commonplace. Growing up in the 1970s my grandparents still had an old version in their garage. (It's still functioned, but wasn't used)

Probably not that effective if the humidity is over 50% in your area.
These types of setups mimics a swap/evaporative cooler.

swamp coolers perform poorly in high humidity. the water capacity in the air is already close to saturation so evaporative cooling like a swamp cooler can't transfer much water into the air

5/10. Thats a humidity increasing fan. You are adding water to the air and reducing your body's cooling ability.
Maybe 7/10 if the ice cube fan is drawing in hot air directly from a pc desktop exhaust
