Ok gotcha thank you LeftyRighty I'll do one fan for now if another is needed I can always add. But will use the larger vents as you suggested. To small is bad if to big can always close it a bit more.
They use static pressure loss of 0.10 to 0.30 inches of water across the the leaf, to guage air flow. I'm still trying to figure how to do this, or what it means, in a mini-chamber.
As I understand it some fans are designed (form, blade curvature) to generate a fixed pressure. Big vacuum cleaning systems are a prime example. A static pressure is generated and the energy used by the motor is a function of FLOW not pressure. Would that idea be useful in this application?Yeah, I agree with you on that - am trying to figure out a decent velocity, since pressure or cfm/lbs is a poor criteria for a DIY home curing chamber. But then you'll need enough velocity pressure to make the exhaust work.
This is getting complicated.
Also, need to be sure the air passes through the leaf, not short-circuiting around it. Not as easy as it seems. Unless you're blowing enough air that leaf is flapping in the breeze.
I don't understand after reading through many post it seems the trend is toward automated humidity control. It seems to me that no matter the home made chamber the user will need to get to know it, in doing so knowing where to set the damper / valve / would become known. So why not manual control?
Has any one made a chamber with a automatic humidity control? If so how?
way to dry, add mist. It is going to be a touchy feely thing which is going to have to be learned
Be careful with liquid water! If it gets on the leaves it will leave brown spots. I agree with the touchy feely thing, nothing is set in cement yet. It may take several seasons to settle this.
it is all going to be careful
Am thinking the heat and humidity could be separately controlled.
To me it seems to be the easiest way to go. One thermostat set to heat and the other (wet bulb) set to "cool". That and it's apples and apples to published data.
Tested PVC pipe for temp result not good.
AmaxB..... you never answered my question, and I'd like to know, since I'm planning to use PVC pipe. How did you test, and how did it fail? Don't want to go to CPVC, but will spend the $$$ if need be.
