How an RV Refrigerator Works
By Mark Polk
You need to have a basic understanding of how an RV refrigerator works.
For starters, keep in mind that your RV refrigerator is different from the one in your house. Your RV refrigerator doesn't use a compressor or any moving parts for that matter. It works off of the principle of absorption. Instead of applying cold directly the heat is drawn out, or absorbed. The theory is, when there is an absence of heat there is cold. Basically your RV refrigerator uses heat, either from an electric heating element or LP gas flame. The heat starts a chemical reaction and then through evaporation and condensation causes it to cool. It also works off of gravity, freezing the freezer compartment first and then dropping down to the refrigerator compartment.
The RV must be fairly level for the refrigerator to operate properly. Older RV refrigerators required more precise leveling, but even the newer models need to be close to level for optimum performance. Over time a cooling unit operated out of level will be permanently damaged. Traveling with the refrigerator on will not cause problems because the liquids and gases in the cooling unit are constantly moving around. They don't collect and stay in areas of the cooling unit like they can in a stationary, out of level refrigerator.
RV absorption refrigerators do a great job for RVers.
Happy Camping,
Mark
