SUMMARY

Using a fridge to cool a room is ineffective; it expels more heat than it absorbs, ultimately raising the room temperature. The discussion suggests that utilizing a canvas roof with water buckets can be a viable cooling solution. Evaporative cooling through water can effectively lower temperatures, especially when combined with reflective materials. The canvas option is recommended for renters due to its cost-effectiveness and portability.

PREREQUISITES
  • Understanding of thermodynamics related to refrigeration
  • Knowledge of evaporative cooling techniques
  • Familiarity with reflective materials and their thermal properties
  • Basic concepts of insulation and its impact on temperature regulation
NEXT STEPS
  • Research the effectiveness of evaporative cooling systems
  • Explore materials for reflective roofing, such as shiny metal or white coatings
  • Investigate insulation options for ceilings in rental properties
  • Learn about the principles of heat transfer in enclosed spaces
USEFUL FOR

Homeowners, renters, and anyone interested in cost-effective cooling solutions for hot climates, particularly in urban settings like Bangalore.

good / bad ideas:
1. have an extra fridge. small 170 litres. can i use it like an ac - cool the room? switch it on and leave the door ajar?

2. buy five-six 15x15 feet white canvas, put it on my roof. put 2-3 buckets of water on roof. canvas acts as a buffer between main roof and sun. water helps keep it all cool

its summer in Bangalore and new place is on the top floor so hotter than before!

like to know if i should try any of these? is 1 bad? will 2 be effective at all?

1 is not good. The fridge takes heat out of the air inside it and pumps it out the back.
As the fridge needs energy to operate, more heat comes out the back than is taken out from the inside. It would heat up the room.
 
lol ty :-) so i guess this old ts to the fridge grave yard for this old chap

anyone on the canvas idea? need to buy them, would help to know if it will help at all
 
Evaporating Water is fairly effective. You can increase the rate of evaporation by using cloth creating a larger surface area. Putting something reflective on the roof also helps. White is better than black, shiny metal is better than white.
 
How about better insulation in your ceiling?

its a rented place so 'i think' canvas will be cheaper and can be sold when moving out

and another ceiling will make for less space ...

will go find prices weekend ty all
