They include analyzer, a rectifier, and two heat exchangers. ), the controlling of that absorption process has changed greatly with the advent of printed circuitry and automatic mode switching, but the actual application of the theory of absorption remains quite constant yet today. In short, heat from inside the freezer is transferred through the pipes of the low temperature evaporator and released to the exterior. An absorption refrigerator is the most efficient when using propane, but less efficient when using electricity. However, if you find that you need to do so, just locate the tank where ammonia is stored and fill it up as needed. RV refrigerators are specially made for RV's and they work on absorption principle unlike compression mechanism used in home refrigerator. Here the hydrogen vapor rises back up to the evaporator section while the ammonia is mixed with water in the absorber vessel, flows to the boiler and the process starts all over again. Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid. The refrigerator has five main parts: Heat is applied to the ammonia and water solution in the generator.
