A scientific illustration showcasing the evolution of refrigerants through time. In the foreground, a collection of chemical formulas and molecular diagrams depicting the transition from early chlorofluorocarbons (CFCs) like Freon to more environmentally-friendly hydrofluorocarbons (HFCs) like Puron. The middle ground features vintage air conditioning units and gauges, contrasted with modern, sleek HVAC equipment. The background depicts a timeline of refrigerant development, with historical events and technological advancements fading into an atmospheric, moody landscape. Realistic, technical, and informative - this image provides a comprehensive visual guide to understanding the progression of refrigerants used in air conditioning systems.
