A gas refrigerator is only cost effective when there is no access to electrical outlets. They are otherwise costly and are used mostly for travel trailers and RVs.
An electric or gas refrigerator was a relative rarity in 1930. They were quite expensive compared to the average wage. A new gas refrigerator cost about $150 in 1930s dollars.
There are plenty of advantages of gas fridge for a cottage. However, the main effective which a gas fridge for a cottage is running even when the electricity is off.

Natural gas is generally more cost effective since it cooks quicker and costs less.
Propane can be slightly more cost efective to opperate.
CFC gas is used for cooling refrigerator.
It is definitely more cost efficient to buy a new model refrigerator as opposed to replacing a part on an old one. The newer models are high energy efficient and will cost a lot less running than the old ones.
bio gas is very useful and it is not causing any pollution and it is also cost effective and the gas emmited by it are used for cooking and it is also
Methane
Gases in a refrigerator are used to transfer heat from the inside to the outside of the refrigerator. When the gas is compressed, it becomes hot, and when it expands, it cools down. This process allows the gas to absorb heat from inside the refrigerator, keeping the contents cool.
It depends on how far the item must be shipped, compared to the cost of gas to drive to a retailer. Obviously, having an item shipped to CA from NY would be more cost effective. However, shipping an item from a store three miles away would likely not be cost effective.
When the gas in a refrigerator expands, it absorbs heat energy from the surroundings to compensate for the decrease in pressure. This absorption of heat energy results in a decrease in temperature, causing the refrigerator to cool. This process is known as the Joule-Thomson effect.
