Refrigerator
Thinking of upgrading our basic "B" to a B+ or even a C. Never having one before, a fridge that is, I was wondering what type is the best unit to get. I think most units are AC/DC. OK I get that. Ther...

There are 2.3.2 types of Refrigerators used now days in RV's
1: Absorption Cooling Units..
These are refrigerator/freezers that actually run o heat They can be Propane only (Which is actually a residential unit) Propane/Electric 120 volt (Very common and Propane/Electric 120/12 volt (Becomming more and more rare for the 12 volt option did/does not work that well.
They work by a series of chemical reactions and are powered by a heater... I won't describe it fully but the technology is older than my 65 years.. My Maternal grandfather worked with it in his prime in fact (he died before I was born).
The 2.2 types are electric only fridges.. One is the common Residential like you have in yoru sticks and bricks, It draws from 100 to around 4oo watts of electricity running, bit more for the fraction of time it takes the compressor to start.. This works by compressing a gas till it turns liquid, cooling the very hot liquid in a heat eschanger, then allowing the high pressure liquid to spray out into evaporative tubes which get very cold. Your home fridge will nto do this but a friend of mien worked on a system that uses this technology and hits sixty below (F).. next.
There is a new version of this, Comes in both Residential, RV and "other" formats (Mine is a chest freezer at the moment) This uses a compressor just like the traditional Residential..... only mine draws 36 watts.. The Dometic and Norcold RV fridges using this technology are below 50 watts with the doors closed (Amazing that opening the door makes that big a difference you have to specify) These run on 12 or 120 volts.. Mine is running on 12 cause that is the easiest feed.
