House cooling


The house was hot for the past few weeks due to the drought hitting my area. After surfing around the internet I stumbled on an article describing how to bring cold air into the house while blowing hot air outside. This interest me quite a bit and after much googling I found an article on how to setup a ventilation fan. The whole cost of the project was RM180 and some heavy sweating. Took about one hour set it up but it was worth it. The house is now 1 to 2oC cooler. The only disadvantage is that I can’t leave the ventilation fan on all the time due to it’s high electricity consumption – 80 watt!. Now if only I find a way to harvest the energy of the sun to turn the fan ….. I guess that will be the next project?
