This episode of the BS* + Beer show is a discussion aroundrefrigerantswithJon Harrod, owner ofSnug Planet, andBryan Orr, founder of theHVAC School. Jon shares an information-rich 10-minute presentation that includes a brief history of refrigerant transitions. Topics of conversation include: how refrigerants work in a closed system; specifics of R-410A, HFCs, and “short-lived climate pollutants;” the mission to make HVAC equipment self-contained and leak proof; storing refrigerants; latent heat evaporization and condensation; the idea of using ammonia and propane to replace current and yet-to-come refrigerants; CO2 as a refrigerant; and a bevy of ideas that challenge how we think about refrigerants today.

Enjoy the show!
