Abstract:The characteristics of R236fa and its feasibility as refrigerant of
   ejector refrigeration system are studied.Through the thermodynamic
   analyses on the ejector refrigeration system,the operation efficiencies
   with R141b,R123,R134a and R236fa as working fluid respectively are
   compared,and the advantages and characteristics of R236fa as refrigerant
   in ejector refrigeration system are drawn.The operation system
   performance of the ejector refrigeration system with R236fa in different
   working conditions is analyzed,and the pump power consumption,the COP
   and the ejector critical geometric dimensions are analyzed.When the
   cooling capacity of system is 1 000 kW,the maximum pump power is 58
   kW,the diameter of the mixing chamber is 152 mm,COP reaches 0.35
   maximally.The research results show that the ejector refrigeration
   system with R236fa has better economical benefits and outstanding
   advantages in the design and manufacture of the large-scale
   refrigeration system.
