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 (ie, propane-powered ammonia cycle) fridges were popular in RVs because they used minimal power to run the ignitor, control board, fans if any.

+ | These fridges are often called //three way fridges// because they run on propane in the field, provide heat for the absorption cycle from 12v while driving, and from shore power when available. | ||
Absorption units are rare in vandwelling setups due to size, expense, and need for exterior venting. | Absorption units are rare in vandwelling setups due to size, expense, and need for exterior venting. | ||
