Shouldn't it just be frigerator?? What I am specifically looking at is the prefix "re" [to add the meaning "do again", especially to verbs, e.g. rebuild, remarry] when most things you would put in the Refrigerator are room temperature. I imagine this would even be more so in the past.

My dictionary does say that Latin refrigerare (to make cool) is composed of re- (back) and frigus, frigor (cold).
Re- in Latin does not always mean "back" or "again". Sometimes it is just an intensifier.
Look at request or require or even refried. You aren't doing anything again, just doing it more strongly.
