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...

Put a gallon of water in the freezer, and 2 gallons in the fridge.
Monitor the temperature remotely so the doors don't need to be opened and note the figures on an hourly basis. ambient, inside RV, fridge, and freezer.
If you run just the fridge on electric and route the power through a kill-a-watt meter, some information will become available about duty cycle. My back yard experiments indicated 2:3 with no connection to the ambient temperature once the fridge had finished cooling down.
Thanks for offering to do this.

With HVAC the biggest issue is insulation.
I do have one of those 7 foot tall fridge/freezer at home and it does use the same size compressor the 5 footer does, yet the huge freezer goes below 0F easy.
I assume the insulation and door gaskets is playing huge role here.
Just for the sake of it, we are expecting 100F this weekend.
I will start my ammonia refrigerator and see how low it will go.
My plan is to start it before noon in full heat and time it.
Any other suggestion for the test?
