Window(s) size 3.5 feet* 5 feet (width)
Fan (2 nos.) Specifications Product page - specifications
Sweep size: 400 MM
Air Delivery: 75 CMM (What is the formula to convert CMM to CFM?)
Volume of the premise : 7200 Cubic Feet
High and Low Temperature day cycle (extreme during the year):
Summer: 45 Celcius - 29 Celcius (Comfort Target 22 Celcius)
Winter: 26 Celcius - 8 Celcius (Comfort Target 26 Celcius)
Purpose: To take the advantage of Temperature gradient between external temperature and internal temperature. Use fans during the time period when beneficial and put on Air Conditioner (Cooling and Heating) when compulsorily required to achieve last lag of the temperature target.
Note: Premise is a concrete building with no insulation, so its temperature follows the external temperature. (Heats up after external temperature goes higher and cools down after external temperature goes down)
(1) How effectively a single pedestal fan (blowing inward) can bring the outside air in the room if blades are 2 feet away from a fully open window (with the distant window of same size at the other end of the house is kept open)?
(2) How effectively a pedestal fan (blowing outward) can throw the air from the room out of window if blades are 1 foot away from a fully open window (with the distant window of same size at the other end of the house is kept open)?
(3) How effective will be two pedestal fans (one inward and one outward placed at distant fully open windows of the house) for displacing the indoor air with outside air?
