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.
Can anyone point me to purveyors of the hardware to do something like
this? Because I'll have a limited time to build this, I'm looking for
something that uses more-or-less off the shelf gear, and not a whole lot
of custom engineering.
How tightly regulated?
I've been looking into this to make a chamber of that general size that
is around 10-15C and 50% RH (for incubating sausage duplicating an
Italian cave<grin>)...
Most kitchen stuff (refrigerators, etc.) tend to have fairly big
fluctuations of temperature as the compressor cycles, although if you
put a lot of mass in the controlled space that certainly slows it down.
There are also a variety of things like cold storage (for florists, for
example) - they tend to be assembled out of simple building blocks:
insulated wall panels, a cooler unit, a door.
Lab incubators or commercial baking is another source (imagine raising
bread consistently)
However, all these kinds of applications can easily tolerate a 5C swing
in temperature since the thing being controlled is fairly massive and
its internal temperature will vary less.
The challenge with a "small" space is that when the cooling unit comes
on, you're blasting in cold air, and it's not "well mixed".
Thanks!
John
