Résumé

This paper comparatively evaluates the feasibility of R404A, R507A and propane (R290) as substitute refrigerants for R22 used in most low temperature and transport refrigeration applications. The present investigation has been done for a finned-tube condenser based on a segment-by-segment simulation model, which is validated with experimental results from published literature. The performance simulation and comparison of the finned-tube condenser using the refrigerants are carried out at different inlet air temperature and velocity to mimic the actual space conditions. The results show that R290 has lower pressure drop, lower mass flow rate and higher specific heat transfer than R22. Although R404A and R507A have higher specific heat transfer than R22, both of them have larger pressure drop, and bigger mass flow rate. Overall, R290 offers better performance and reliability than R404A and R507A, and can be used as long term substitute refrigerant for R22 in low temperature and transport applications.
