Excerpt from: "The History of Gas Refrigerators and How Gas Refrigeration Works"

What is the history of the absorption refrigeration system?

HISTORY - The ammonia refrigeration cooling system which is also known as an absorption cooling system was first discovered in 1824 by Micheal Faraday who tried to liquefy gases which, among them was an ammonia gas. This experiment was used in taking ammonia vapor in a glass tube with silver chloride in it and allowing it to absorb in the silver chloride powder. He then heated the chloride -ammonia mixture and watched the ammonia liquid evaporate out of the silver chloride and become cold. This experiment later was the birth of the ammonia absorption cooling systems [HEREAFTER CALLED PROPANE REFRIGERATORS].

In 1926 Albert Einstein and a former student, Leo Szilard, embarked on a venture to develop a safer refrigerator since the electric refrigerators of the time were known to leak toxic gases through broken seals. Such an incident of a German family killed by fumes caught the attention of Einstein and sparked this project. Einstein insisted that a better refrigerator design must be possible.

Their goal was to design a device with no moving parts or mechanical motion and eliminate the wear and tear factor. They used their knowledge of thermodynamics to produce an absorption refrigerator. This device would drive a combination of safer gases and liquids through three interconnected circuits. It required only a small gas flame as a heat source and was totally sealed and safe. Some experts estimate the sealed system could last 100 years.

Einstein and Szilard applied for and received 45 patents in 6 countries for this type of refrigeration technology. None of their inventions ever reached customers. The introduction of the less-toxic coolant freon and better judgment kept Einstein and Szilard from continuing the project.
