RefrigeranT & Lubricant Chemistry and Interaction

125 Years of ASHRAE: What I have learned in the last 35 years

When I joined a hermetic compressor company as a research chemist back in the early 1980’s I was quickly introduced to ASHRAE. The first project I worked on was to construct a manifold assembly used to make glass sealed tubes based on ASHRAE Standard 97. Years later I was attending ASHRAE conferences and sitting in on various technical committees dealing with refrigerants, lubricants, contaminant control and system chemistry; listening to what was going on in the refrigeration and air conditioning industry. I was introduced to individuals who were working on similar projects that I was and learned how ASHRAE research worked, the value of handbook chapters, various programs I could attend and yes how standards where developed and implement like what I learned in Standard 97. 

35 years later I find myself still in the industry utilizing ASHRAE, have a son that is also in the industry and now I try to be a leader and mentor. This paper will focus on what I have learned over the years that has helped me and my industry peers advance the art. It will look back to how these functions have been shaped and look forward to what’s next.
