Description

This research project involves an in-depth study of the effects of different classes of chemicals identified in manufacturing process fluids on the stability of R-134a and POE lubricants. The project is divided into three parts with the following objectives:

Part I:

  • To conduct a literature search and review to identify the classes of fundamental chemicals that are likely to produce significant interactions with the HFC/POE system.
  • To compile a list of chemical classes that are known to be present in commonly used process fluids.
  • To review the chemical classes and chemical species that are present in process fluids and that are also most likely to come in contact and react with the HFC/POE system.
  • To select fourteen different chemical species for an in-depth experimental study.

Part II & III:

  • To conduct sealed tube tests of the fourteen selected chemical species with R-134a/POE.
  • To determine whether and under what conditions of initial concentration and aging temperature the selected chemical species are reactive in the R-134a/POE system.

When possible, to suggest reaction mechanisms, calculate reaction rate constants from the effects of aging time on the concentration of decomposition products, estimate the orders of reactions, and obtain Arrhenius plots based on the effects of aging temperatures on reaction rates.”
