New high performance, low GWP refrigerants for stationary AC and refrigeration.

Author(s) : LECK T. J.

Summary

In response to concerns about global climate change, and in consideration of probable legislation that may impact the production and use of refrigerants with high global warming potential, a set of new refrigerant candidates has been developed for evaluation. Some candidates are designed for stationary air conditioning in residential and light commercial end uses. Other refrigerant candidates were designed more specifically for use in medium temperature refrigeration applications. These candidates all have GWP values that are reduced significantly from R134a, R410A and R404A values, and have good predicted performance characteristics as determined by cycle modelling. Model results must always be validated by actual system tests, and that work has been underway for some time now. System tests are indeed showing that the predicted model results are achievable. This presentation describes these candidates and show some results from evaluations of their cooling and heating performance properties and LCCP (life cycle climate performance) comparisons.
