Over the last 150 years, we have learned how to use a number of different refrigerants. The first refrigerants were ammonia, ethers, methyl chloride, air and CO2. Later, hydrocarbons emerged, and in 1930s we saw the first series of CFCs, mainly R-11 and R-12, emerging on the market, followed by HCFCs such as R-22 and R-502. Of those refrigerants that preceded CFCs, only ammonia remained on the mainstream market, with CO2 and the hydrocarbons disappearing. Ammonia was used in large industrial systems in many countries because it was very energy efficient.
