As the F-gas regulation drives the HVAC industry toward refrigerants with lower global warming potential, propane has emerged as a leading alternative. However, its flammability presents new safety challenges. Integrating gas sensors into refrigeration systems can mitigate these risks by detecting leaks early and enabling preventive action. This talk will explore the role of gas detection in ensuring safe propane use, compare available sensing technologies, and provide guidance on selecting the most appropriate solution for specific applications.
