When you are talking about efficiency, have you considered the energy consume to turn it into ice? The energy of the fan to constantly blow at the ice. Compare with air-con who does not have to freeze water into ice at the start.

what if ice is not found ?

This is a thing called air-con that using this concept.

The refrigerant in the compressor in your "ice" lah, don't need so troublesome, energy inefficient to replace ice.

or more conventionally, freeze the ice in the middle of the night where the temperature is cooler and no one is in office, store it, and use it for air con during day.

this concept ady available in the market long time ago.

I not able to get the pic.. but then the shape is look like a Mini fridge / air purifier.

U can remove back cover to put the ice into a box behind. Then refill once the ice melted.

Its china made if not mistaken. But then throw it since not really 100% works.

Troublesome refill ice, and its not really cold like air-cond. And noisy of course.

Updated: Its Air Cooler Fan. google it for pics. thx

Pity it is not efficient enough to sustain the ice cube as it will melt. Instead of re-invent air cond , personally I think it is a good idea for TS to do research how to keep the cubes in solid form to be used in other application

Actually I've thought of something similar. When it gets too hot, and you need to cool down fast without the equipment.

Just get some ice, and place them infront of a table fan facing you.


Good work, keep it up.

And this is key ( =

The tariffs for off peak hours would be lower too, so money is definitely saved.

When it is hot on afternoon...

go places with aircond,

so they don waste energy and you'll get good temperature..

i concur. my faculty uses such cooling system.

at night when energy needs are at its lowest, the system uses up electricity to freeze the water.

during the day, the ice is used to chill water, which is then circulated throughout the building. the chilled water runs thru coils in the air ducts, which in turn chills the air.

very cost effective for large complexes, considering the cost of water over refrigerants.

if i'm not mistaken, one such system will be built in putrajaya too. i knew this when one of their consulting engineers came to our faculty to give a talk.

TS,
i don this is not so practical. further innovation need to be made so that it become a nice invention. Plus, this is more likely to be a simple machine to speread the cool air from the ice, but not a mini air conditioner.

if TS really wants to pursue mini AC, he shouldn't use water.. i mean; indeed water is dirt cheap compared to refrigerants, but to freeze water uses up energy too. it won't be cost-effective in the long run.

don;t try to find new way to cooler down heat Mark Lampard....
Albert Einstein said air-cone = everything

During my evening class, I bought a lot of ice pack and put it into a big bowl .. that time I got not enough moneh to afford extra gas + my home 40km from home .. and I tried to sleep in car, too sleepy liao ... half an hour passed

The result : Failed liao ... I'm still sweating and wet inside car ..
