Shop Refrigerator

[Steve Shipley <shiples@comcast.net>]

I have a refrigerator in the shop.  I went out to get an ice cream cone the
other night and it was barely frozen.  Since we recently got our first freezing
weather, I was wondering if a refrigerator is affected by the outside
temperature.  The shop is unheated so I'm pretty sure the temperature was
around 32 degrees for a day or so.  Does a refrigerator depend on the 
temperature
to function?
