Analysis the characteristics of R1234yf, R1234ze, R134a on reefer container

Abstract

In this work, the characteristics of R1234yf, R1234ze, R134a on reefer container were studied. According to pressure enthalpy (p-h) diagram, a computer code developed by Matlab was used to calculate power consumption, coefficient of performance (COP), compression ratio, discharge temperature, etc. The result shows that, at the same degree of subcooling and superheat, the power consumption, discharge temperature and compression ratio of R1234yf is higher than that of R1234ze, R134a. The COP of R1234yf is maximum. R1234yf can be used as an environment-friendly replacement for R134a in reefer container.
