What is an absorption refrigerator?
Absorption refrigerators, sometimes called three-way refrigerators, rely on a gas flow heat exchange system located in the back of the refrigerator to extract heat from the refrigerator and cool the internal temperature. Absorption refrigerators have three means of being powered; 12-volt battery power, 110-volt battery power, and LPG gas.
What are the pros and cons of an absorption refrigerator?
Pros: 1 Absorption refrigerators can run for an extended period of time because they rely on the gas flow exchange system rather... 2 You will not need to spend additional money on batteries and charging systems like solar power to run. 3 The heat exchange system of cooling means the refrigerator runs completely silent.

Is a compressor fridge better than an adsorbtion fridge?
Compressor fridges are much more effcient than adsorbtion ones because they use a pump system rather than just a heat exchanger. However, the downside is they make more noise. Try sleeping in your kitchen and you will get the idea. In small vans as long as you can live with the noise they will be better.
Which is best absorption or compressor fridge?

Residential refrigerators
I first saw the residential refrigerators pop up in the RV market back in the late 1990s, but only on the larger diesel rigs. The reason was, people were getting frustrated with the RV refrigerators that didn’t cool very well in extreme temperatures. Also, there was the fear of fires as well as the recalls, which we will discuss later.
How the compressor-driven refrigerator works
A residential refrigerator uses an electrical compressor to compress the refrigerant inside. The compression results in the refrigerant raising its pressure while getting very hot and traveling up through the coils on the back outside of the refrigerator. Once the hot gas meets the cooler air in the room, it turns into a high pressure liquid.
The advantages of a residential refrigerator
The electrical compression method works better in hot temperatures and cools down faster when you are getting ready to take a trip. It also works better in high altitude, although I do not think this is a fair comparison.

A rich solution of ammonia, water, hydrogen, and sodium chromate is kept in the absorber vessel and flows to the boiler, where it is heated by either a flame on propane, or a heat element on 120-volt power. The ammonia turns to a vapor and travels up the pump tube to the condenser fins at the top of the refrigerator on the outside.
