Hi there,
I need some help with correct fan sizing for a 30m x 8.5m x 3.35m(h)/ 100' x 28' x 11'(h). The added challenges are having to push or pull everything geothermal tubing, whilst not being so loud/power hungry.
There is a lot to plan and not enough info readily available on the topic. I would like to push/pull the hot air out of the greenhouse and through 20 pipes each 30m/100ft located 1.8m/6ft underground and back up into the greenhouse.
I did a whole design with a solar chimney, but sadly, that would only pull approx 800m3/h / 28251ft3/h (life must be hard in the US with all those big numbers), and I need minimum 3300m3/h... 116538,4ft3/h. Best would be 10000m3/h......... 353146,67 ft3/h
Pressure is also an issue, when having to pull air through 20 pipes and a 100ft greenhouse (pic 1) or with a different design just recirculating the air through the tubes (pic 2).
So this discussion should be about fan sizing and correct pipe layout to save on fan pressure.
