The Chilling History of Refrigerants: from Ether to Modern A2Ls

Ever wondered what refrigerants really are and how they've evolved? In this video, we dive into the fascinating history and science of refrigerants, from early evaporative cooling to today's advanced A2L refrigerants.
We cover:
The basics of evaporative cooling
Benjamin Franklin's experiments with ether and alcohol
The birth of closed-loop systems
Early refrigerants like ammonia and methyl chloride
The game-changing introduction of Freon (R12)
Environmental concerns and the phaseout of CFCs and HCFCs
The rise and fall of R410A
Modern A2L refrigerants and their properties
The ongoing use of CO2 and ammonia in specialized applications
Learn why we're moving towards mildly flammable refrigerants and the trade-offs of this move. Whether you're an HVAC pro or just curious about how your AC works, this video breaks down the history and science of refrigerants in a way everyone can understand.
