Can someone explain if natural gas can be use as refrigerant?

First the term “natural gas” refers to several mixtures in different compositions, so you should specify better.

The main components of these mixtures are CO2 and Methane.

Methane has a Critical temperature around -82°C while CO2 around +31°C, so CO2 would behave as an incondensable gas in a Methane cycle.

If you reach the purity necessary for a refrigeration cycle then the term “natural gas” would no longer apply.

There was a company in Aussieland that tried to market a refrigerant that had a significant LP gas content . It is possible to have a blend with LP gas but its just too damn dangerous , who wants to die over a fridge .
I went to a job years ago when that gas was sold and found a 20ft open top Freezer running on it .
I happily left the job without doing any work on it . I thought one day I might see that supermarket on the evening news with the roof blown off and some deaths . I didnt happen there but I think a car A/C system went up in flames ...that gas is not on the market now.

Hi, JackWebber :)


Can someone explain if natural gas can be use as refrigerant?

assuming you are thinking about hydrocarbons ... like refrigerant grade propane (R290) or refrigerant grade propene/propylene (R1270) it is possible, but not that simple ....

Best regards, Josip :)
