| + | * **Con** - constant need to add frozen material and the requirement to dispose of any melted ice. You lose significant amounts of interior volume due to the space taken up by the cooling material. | ||

This type of fridge had to to be quite level so the ammonia cycle cooling would work by gravity; |
| + | |||
| + | 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. | ||
