Interior Structure Additions (Part 2 of 2: Fans and Ventilation)
Note that the heater is on in this image, which also shows the placement to allow for the fans to mix the carbon dioxide and also the heat to prevent stagnate and stratified air inside the structure.
HAV Fan
This Atlas HAV (Horizontal Air Flow) 18” and 1/10hp, 1 amp fan moves 1790 CFM (Cubic Feet per Minute) at 1600 RPM (Revolutions Per Minute) which, will run 24-hours a day so even when the large yellow exhaust fan is off, so the air will continually be mixed.
Exhaust Fan
The large yellow fan is a Dayton outdoor mobile air circulator that has 42” diameter blades and two speeds. On low it will it will run 9,000cfm at 4.6 Amps and on high 15,000cfm at 5.3 Amps. This is an industrial air circulator that has a water-resistant motor which is important because of the mist cooling system I have installed will result in a consistently high humid environment.
Wall Shutter
The fan is placed directly in front of a Dayton 48” Backdraft Damper model # 4FZJ2 which allows for high-velocity applications. There is one in front of the large exhaust fan and two more on the other side that will allow for outside air to be naturally drawn into the structure.
Scaffolding
The yellow exhaust fan sit on MetalTech Safeclimb Baker Style 6ft. x 6ft. x 2.5ft. scaffolding that has an 1,100 lbs. capacity. The wheels were not installed and it was leveled by using heavy duty metal stakes which also provide a solid support system on what is uneven ground.
CO2 Mixing Fan
Under the scaffolding is a black 20” Hurricane Pro Heavy Duty Orbital wall/floor fan that is rated at 4,500cfm and a max 1,400rpm. This fan is pointed at the plant and is intended to help mix the carbon dioxide that will be supplemented. This fan oscillates inside the protective wire cage which is a nice feature.
