Hey Eric,
I've done a lot of testing of interior temp v exterior temp on two
models of ammonia-cycle regfrigerators -- the stock Vanagon one, and a
standalone Dometic RC3000 unit that I use on longer off-the-grid camping
trips.
The ammonia cycle is capable of pulling something around a 40 degree (F)
differential between ambient temperature and internal temperature, and
my measurements agree with this.
If it's a 100-degree (F) day, the inside of the refrigerator will slowly
climb up to 60F. That is above the maximum allowable temperature for
food safety (between 40F to 140F is the "danger zone") and also results
in beer that is warmer than I like to drink.
