Session II 

The Cold Truth about Refrigerants and Refrigeration

Speaker  

Andy Hayes, Heat Transfer Sales, ASHRAE Distinguished Lecturer

Summary  

There’s a lot of talk currently about the environmental impacts of refrigerants. However, unless we opt to completely eliminate the cool comforts of our modern lifestyle, refrigerant is not going away. It will always be a necessary evil in the built environment.

We’ll take a trip down memory lane and review the vapor compression cycle and how the first-generation refrigerant systems performed. We will revisit the high performance and energy efficiency of the first generation of air conditioning systems and reflect on the unintended consequences.

We will discuss the next few iterations of refrigerant blends, focusing on the performance, trade-offs and sustainability sides of all the changes to refrigerant systems and along with the sustainability and environmental impacts.

Where is refrigerant today and what are the the real-life limitations of where we can go tomorrow?
