Refrigerant

1. Chlorofluorocarbons (CFCs): - Examples: R12 (Dichlorodifluoromethane) - Properties: CFCs are highly effective as refrigerants due to their stability, non-flammability, and low toxicity. - Environmental Impact: They were found to be damaging to the ozone layer, leading to increased ultraviolet radiation reaching the Earth's surface. This ozone depletion contributed to environmental issues such as skin cancer and climate change. As a result, their use has been phased out under the Montreal Protocol. 2. Hydrochlorofluorocarbons (HCFCs): ...

Refrigerants Impact on coil design

Refrigerants in HVAC systems can be categorized into different types, such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and hydrocarbons. The choice of refrigerant significantly impacts coil design in HVAC systems. For example, the transition from CFCs to HCFCs and HFCs was driven by environmental concerns, as CFCs were found to deplete the ozone layer. HFCs, like R-410A, became popular due to their ozone-friendly nature, but concerns over their high global warming potential (GWP) led to the development of alternative refrigerants...
