SPONSORED BY DAIKIN - Most ASHPs and VRF systems in the US use R-410A, a well-known HFC refrigerant. In this session we will cover the basics of refrigerants and their role in the refrigerant cycle, and in the coefficient of performance [COP] of these systems. We will also dissect the environmental impacts of HFCs from their Global Warming Potential [GWP] to their Life Cycle Climate Performance. The life safety implications of HFC refrigerants will be discussed, with an introduction to the ASHRAE 15 & 34 standards. We will review previous and current phase-outs for refrigerants, as well as look forward to the next refrigerants for ASHPs and VRF, and building code implications and limitations that are involved.
