Ammonia versus Compressor Fridge...
After all the talk about Danfoss compressor fridges and how much better they were than the old school Ammonia Units, I decided to 'fiddle with mine and do a long term test using a remote digital recor...

I am bumfuzzled. :h Everything I've read up until this thread had led me to understand that ammonia rv fridges can't achieve more than about 35 degrees difference from ambient temp. Everyone said so; it seemed to be "common knowledge." This alleged "fact" would translate to a fridge temp of about 65 degrees if the outside temp was 100. But a couple of you folks seem to be indicating that your fridge temps hold steady below 40* even when it's 100* outside. Unless I've misread, I need to completely re-adjust my understanding of these fridges! Or am I missing something? :?
I should add that my last two trailers had small (2.5-3.0 cu ft) units with side venting only. Their performance was abysmal. I did manage to get right around that 35* differential when I hung an O2Cool fan just outside the upper vent to suck air out through the vent system at a high rate. I can't imagine how that fridge could have been capable of a 50 or 60 degree temp drop, though!
