From household refrigerator to cooling chambers and passing by air conditioners of all types, refrigerants are widely used in both industrial and domestic equipments. These fluids, which are henceforth being banned due in particular to their environmental toxicity, are expected to be replaced. Replacing them is a difficult task considering that the only solutions currently available are the so-called “natural” refrigerants, such as ammonia, hydrocarbons and CO2. The disadvantages of these products are mainly toxicity (NH3), flammability (HC) and high pressures (CO2). However, with minimal skills and compliance with safety rules, they do not eventually prove to be more dangerous…
