The RV Fridge Wiki page will use drawings to share the physics governing the process used for common RV refrigerators, discuss safety, and tie together the science for this widely misunderstood refrigeration process.
In recent years residential refrigerators have become popular with larger RVs. The residential type refrigerators are generally of the vapor-compression refrigeration type. There are many drawbacks to residential fridges due to the energy that they require. For example, if one is not plugged into the municipal power grid an RV needs to store enough electrical energy to run the residential type fridge. The expense can be very high for running generators, installation of the proper type of inverters, battery replacement, and solar systems. This page will focus on the absorption refrigerator due to the fact that it is easy to sustain these fridges as long as propane (LP) gas is available.
Following is a block diagram and a simplified drawing of a typical absorption type RV Fridge. The block diagram is a simplification of the fridge cycle which shows the key components combined with the fluid flow within the circuit. The simplified drawing more closely resembles the actual refrigeration cycle so that the reader can draw a connection between the components on their fridge and what is occurring within the tubing.

The block diagram shows the flow of the fluids (Qx) which includes both gas and liquids between the components of the pressure vessel which is commonly called the cooling unit. The yellow line and flow Q1 is the holding tank mixture of liquid water, ammonia, and a rust inhibitor. The flow direction is identified by an arrow next to the fluid flow ID Q1. Also, the heat input (endothermic processes) and heat rejection (exothermic processes) for the respective components has been identified for each component.
