Im looking for an effective way to set up a passive air cooling system to keep the house cooler and keep the humidity down. I think a lot can be accomplished with our house by creating conditions that provide air draw through the house. I am also going to work on creating some shade over windows and the south side of the house.
As for air movement, one thought I had was taking a roof vent turbine and installing it attached to a pipe or duct that leads into the house instead of venting the roof. Has anybody tried that? I think it could act as a whole house fan except the fan is wind driven on top of the house to pull air up. If we did that, how would we close it up successfully in the winter?
The other idea im toying with involves the basement. We dont have any ductwork in the house- our heating is propane and electric radiant heat. Im thinking of cutting floor vents in the first story and running ductwork down to open near the cement basement floor. The walls are insulated down there, and the floor is going to be sealed to reduce humidity and moisture transfer. I think these two ideas together will create a stack effect that will draw cool air up from the basement and vent hot air out of the roof.
Any thoughts or ways to expand the concept would be appreciated!
I think it the brilliant idea, I have never tried this before but I will surely give a try. The passive cooling can be adopted as a viable alternative to conventional cooling system. In architecture, passive cooling refers to a building that uses no energy-consuming technology or devices in order to help maintain a comfortable inside temperature. Some common methods of passively-cooling a house include properly sheltering it from the sun, utilizing a reliable breeze, and using a nearby water source to cool the local air temperature.
The passive air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases, and hence make sure that the air conditioning system is in proper working condition, we have to clean it regularly for that we need to contact the professionals like
