General / Off-Topic 30ºC in my room, how to cope with the heat ?

Stand a bowl full of cold water and Ice behind your desk fan. The fan will drag the cold air towards you, Humidity will increase, so balance is everything, Have 2nd fan pointing out of a window. This will draw air out of the room and create circulation. No Fan, Then put the bowl of water and Ice up "High", Cold air falls warm air rises. Sit on the floor to play, and have your PC low in the room :)

Buy a A/C...

Or we could make it complicated.

Build cold reservoir and hot reservoir, install pumps and and let "something" could be water, circulate from hot to cold.

(Thot−Tcold)/Tcold to know the maximum capacity Thot>Tcold W=cV×δT×N×10%W=cV×δT×N×10% ,where δT=30 KδT=30 K is the temperature difference, NN is the mass/number of air (particles) and cVcV is the heat capacity.

But as I said, keep it simple, buy a fan or a A/C :D

I live most of the year in the tropics, I got a pool, water vapors in front of high speed fans outside, also using natural wind compression to cool my house down plus of course A/C when it gets too hot.

The best PC-related cooling I ever had was a few years ago on a hot summer evening. My PC kept dying from heat so I opened it up and found it had become dust-city in there. I reached for a can of compressed air and diligently blasted every component and filter clean and clear of dust before sealing back up the case (dust outside).

Not only did my machine run smooth for the rest of the evening but the compressed air can had chilled to almost sub-zero temperatures with use. Putting that ice-cold can against my forehead and neck was heaven :)

I confess ignorance of the formula, but I'm staying far from any maximum capacity Thots. :)

Your house sounds well designed.
I built on a hill, excavated on the eastern side, placed the garage to face the prevailing wind in the lowest excavated level, and used it as a shaded air intake. The garage doors are just a steel grill.

The central stairwells drive the wind through the building. The mass of the hill shields the lower levels from the worst of the sun. In the Caribbean, the heat is sometimes too much for passive cooling, but so far we haven't needed AC.

I ran water pipes painted black in a plain grid over the exposed west wall, covered it in glass. The flow cools the wall, and they work as a solar preheater.

I'd like to see your professionally engineered setup though. Sounds better.

And it's all zero energy rated, I can pull the plug and go off grid if I want to :)

Pumps for the pool runs on solar power, water collection from roof area collected in a small grey water pool, where i got some plants to natural filter the water. Then it's pumped (solar driven pumps) to a small water tower during daytime (kinetic energy storage) :)

The collected water is used for showers, washing machine, dish washer, the filtered a second time and used to flush the toilets :D

All the crap goes to a biodegradable area where fast growing plants are using it to, well grow.
I got a truck who empty the main tank every 6 month, however I can run it 100% off-grid, but then there will e a bit of smell from it when the wind direction is in the "wrong direction", not much just a little. But my daughter and wife don''t like that so we get the truck :)

Spend a lot of time building it, but now I'm good :)
