Kitchen Large Electric Appliances - Replacing Freezer Thermostat With Wal-Mart Digital Home Control?

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? :confused:

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 have a bad link.

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.

If you tell us exactly what you are trying to do it would help.

Refrigerator Thermostat (http://www.homebrewers.com/product/BE875/Refrigerator_Thermostat_by_Johnson_Controls.html)

Yes, I know how to control humidity in the range I desire
in an airtight box. I am not asking about humidity. I am
asking about temp. control.

How more explicit can I be than to say I want to replace
the thermostat in an existing freezer with another with
a different range and run it? I don't understand what
else you could need to know.

I have been told more than one source that a box as well
insulated as a refrigerator without power will generally maintain an internal temp. of near 72-75F even if left outdoors as long as it is ALWAYS in shade. This is from
people who incubate bird eggs.

I would think that compressor would hardly ever run
within my parameters. There would likely be a significant
period between compressor run cycles. Maybe I just
need to experiment. I have gotten a few negative
responses from people but no one seems to be able to
say for certain.

You may have received negative responses because maybe people are telling you something you do not want to hear.

I am not sure where you can ask the question you did and then say that you did not want to control humidity???

The above statement is false.
If an insulated box was placed in an environment that was at an elevated temperature it will reach equilibrium at a rate that the insulation allows the transfer of heat.

So, watcha building?
