Summary

AHRTI (Air-Conditioning Research Technology Institute) sponsored a research program on developing essential low GWP refrigerant database in collaboration with Oak Ridge National Laboratory (ORNL) and National Institute of Standards and Technology (NIST). In 2019, AHRTI received a US Department of Energy Building Technology Office funding award to carry out this research program. As part of the overall effort, Trane Technologies conducted AHRTI Project 9016 – Chemical Stability of Low GWP Refrigerants with Lubricants.
This paper summarizes the results of highly accelerated life tests (HALT), conducted according to ASHRAE Standard 97 sealed glass tube methodology, for refrigerants R-1234ze(E), R-450A, R-515B, R-1234yf, R-513A, and R-516A with and without lubricants. The lubricants studied were polyalkylene glycol (PAG), polyolester (POE) and polyvinyl ether (PVE). The study also included evaluation of HFC blending components R-227ea and R-152a.
