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.

The Natural Gas Refrigerator

Do you have a natural gas well on your property? Is electricity overly expensive? Are you tired of the annoying noise the compressor and fan on your electric refrigerator produces? Are you EMF intolerant? If you answer yes to any of these questions, then a natural gas refrigerator may be just the thing you need.  This technology has been around for nearly 100 years and was very common in households during the 1950’s. It has since faded from the household due to the abundance of electricity, but has continued to be the system used in Recreation Vehicles. Read more – click here.

Considering that an electric refrigerator is the largest energy hog within a normal household, using a natural gas refrigerator can save you hundreds of dollars per year. Some properties include a natural gas well and for those lucky enough to own one, a natural gas refrigerator is the best way to go since it would cost nothing to operate. Other households are experiencing sky rocketing electricity prices. Eliminating the electric refrigerator is the single appliance that can lower your electricity cost the most. Compare your electricity rate of 1800 watts per day to the cost of a natural gas refrigerator consumption of 1200 BTU per hour of gas usage.

The noise of an electric refrigerator fan and compressor  can be quite annoying and for those that are Electro Magnetic Field intolerant, a gas refrigerator can be a great relief. There are no moving parts on a gas fridge which translates into silent operation in addition to less maintenance and no parts to break down. These units are completely non electric. The refrigeration is produced by an absorption system that uses heat, pressure, and gravity to create the movement of the refrigerant. The EZ Freeze brand gas refrigerator includes no motors, compressors, fans, or circuit boards. The EZ Freeze brand is made specific for household use whereas the RV refrigerator models are not. Even though some people elect to use these RV models in the house, they do require electricity to operate them  from gas and incorporate circuit boards, electronic igniters, and solenoids.

Gas refrigerators operate from either natural gas or propane gas and can be easily converted to one or the other with the change of only a couple parts. Usually taking only a few minutes for the conversion. The big difference in these two types of gas is in how the gas arrives to the refrigerator. Natural gas is generally piped in from an off property source such as a local gas company through their own metering system. Some lucky few do have natural gas wells on their properties without outside metering. This source requires a constant flow from the supplier or well. Propane is a liquid gas that is stored in tanks and is generally trucked and pumped into a storage tank located on the property. In this case the energy is “stored” and can be used full time or just in case of emergencies or natural disasters.

Too some a natural gas refrigerator can be a great alternative and to others it can be necessary for survival.
