Due to Regulation EU 517/2014 (F-Gas), the use of refrigerants with GWP higher than 150 was limited from 2015 on in small capacity refrigeration systems in Europe. Although refrigerants that dominate are R600a and R290 nowadays, which are classified

A recent trend to spread the use of CO2 refrigeration cycles in warm regions of the world is to combine a CO2 cycle with another one using a high performance refrigerant. Two alternatives are being considered: cascade and mechanical subcooling system
