Course Description

Refrigerants are substances used in HVAC systems to transfer heat and enable cooling or heating. They are critical to system efficiency and performance. Common types include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and natural refrigerants such as ammonia and carbon dioxide. Understanding refrigerant safety is essential because improper handling can pose significant risks to both human health and the environment. Over the years, refrigerant technology has evolved, shifting from high ozone-depleting substances to modern low-GWP alternatives, improving environmental sustainability. These chemicals are present in a wide range of applications, including residential air conditioning, commercial refrigeration, and industrial HVAC systems. Their chemical properties determine both performance and safety, making proper management critical to prevent leaks and environmental contamination.
