R32 vs R410a: A Complete Comparison – hvacshop.com.au

WebApr 20, 2024 · Because R410a has a GWP of 2088, it can generate 2088 times more global warming than carbon dioxide. R32, on the other hand, has a GWP of 675, which indicates it can cause 675 times more global warming than carbon dioxide while being far less destructive. As a result, having a lower GWP is healthier for the environment. WebMar 17, 2024 · Freon and refrigerants have more similarities than differences.
