I've seen many videos and read many websites, including commercial websites. I've seen circulation rates from 3 to 7 times an hour. I've seen pipe diameters of 3"/6" and 4"/8", and I've seen different suggestions for the battery length. I'm very confused. Which of these is right, which is wrong, and which depend on the size or design of my
greenhouse? How do I determine what is right for my
greenhouse?
I'll be building it in southern Vermont, on the north side of a mountain unfortunately. I'll have an orangarium that will be either 20'x30' or 30'x30', I'm planning on putting a hot tub in it and I'll build a
RMH for seating around the tub. Connected to the orangarium will be three connected greenhouses, each 20' by 34'. I plan on keeping each at somewhat different temperatures most of the time. Behind the north wall I'll have additional rooms for a kitchen,
mushroom rooms, offices,
aquaculture, etc., which I plan on heating with RMHs. I'm planning on four climate batteries, one under the orangarium, and the other three under the greenhouse sections. I don't plan on extending the climate batteries under the offices. I'm not sure how tall the building will be yet, I'm still working out roof angles.
Are there formulas/calculations I can use to determine the best pipe diameters, lengths, fan capacities, etc.?
