| - | === Absorption refrigeration === | ||
| - | Absorption (ie, propane-powered ammonia cycle) fridges were popular in RVs because they used minimal power to run the ignitor, control board, fans if any. This type of fridge had to to be quite level so the ammonia cycle cooling would work by gravity; | ||
| - | Absorption units are rare in vandwelling setups due to size, expense, and need for exterior venting. | ||

| - | Over the last few years RV refrigerators have been going to 12v or, more commonly, 110v residential style units. | ||
