I may have the opportunity to build a small "clock room" and am
considering whether I could make it an environmentally controlled space.
I'd like to learn about the options for doing this.
The space would probably be 6x8 feet or so, in a basement with one
outside wall.
I'm lost with the basic concept here. Help me understand this.
This room would be a large closet in my basement where two racks of
various OCXO, Rb, Cs live. There wouldn't be a lot of in-and-out
traffic. I'm not looking for 0.01 degree regulation -- <1 degree C and a
few percent humidity throughout the year seems a reasonable goal.
What I envisioned was a very small heat pump or other heating/air-con
unit coupled with some sort of proportional control. I just don't know
where to start looking for that, or what other issues to be thinking about.
(I know the way time-nuts think, and I recall the great ideas posted
here in the past about using an old refrigerator, or burying standards
in a deep hole -- but this would be wrapped into a bigger construction
project that I'm going to be managing from a distance, so I need to keep
it fairly straight-forward.)
Thanks, all!
John
