 ==== Methods of refrigeration ====
 === 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;  there is no pump.((http://www.doityourselfrv.com/know-rig-level-enough-rv-refrigerator-work-properly/))  Using one out of level could damage the $$$ cooling unit.
+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.  The fridges are very efficient (both propane and 12v controls) on propane, but use a great deal of power to run off electricity.
 Absorption units are rare in vandwelling setups due to size, expense, and need for exterior venting.
