Modern requirements for refrigeration agents in transport air conditioners

Vadym Ishchenko Nadiya Braikovska Iurii Shcherbyna Yuri Demchenko

The Scientific advances, changes in national legislation in the field of combating the effects of global warming and market requirements have stimulated the development of fourth generation refrigerants. In  contrast  to the  first  and  second  generation  refrigerants, which  provided,  along  with  the  principle possibility of  achieving a refrigerating  effect,  such  qualities  as  durability  and  operational  safety,  the third and fourth generations include environmental constraints in a significant way. The identification of a link between leaks of traditional second-generation chlorofluorocarbon (CFC)-based refrigerants and  the  destruction  of  the  protective  atmospheric layer  of  ozone  gave  rise  to  the third  generation  of refrigerants.  The  Vienna  Convention  and  the  Montreal  Protocol  were  the  reaction  of  the  world community,   leading   to   the   banning   of   ozone-depleting   substances   (ODS).   At   the   same   time, hydrochlorofluorocarbons were considered as temporary or transient and hydrofluorocarbons (HFCs) as   long-term   working   bodies.   Interest   in   the   natural   refrigerants   ammonia,   carbon   dioxide, hydrocarbons and water has increased dramatically
