I want to create some sealed environments where I have semi-fine
control over temperature & humidity drift with timing etc.

Is it unreasonable to ask an upright freezer cooling system to
regulate the box to temps in the 50s to 80s F? Is it OK if
the outside ambient might peak at 105F for a couple of hours
once in a while (really not often)? They will probably won’t be in a
climate controlled environment.

I don’t mind some unusual wear and tear but I don’t want to
burn anything up overnight.

I have a book on HVAC and it looks like the similar kind of
compressors are often used between window A/C units and
freezers.

They sell a device on to basically do exactly this (or the temp.
part anyway). Here is the link:

I think it should work just fine…what do you think?

I am quite handy with simple electronics, capacitors, switches,
relays, controls, etc. The finer points of refrigeration I suspect
would take a few years I don’t have right now…

Thanks!

You will not achieve any kind of close temperature control and will have absolutely no control over humidity.

Compressors may look the same but most have a specific temperature operating range.
There are some compressors that can operate at both low and medium temp but it is rare to find this type in a freezer.
