Refrigerant Sensing in the Low-GWP Transition

As the HVAC/R industry transitions to low-GWP refrigerants, engineers and OEMs face new challenges related to safety, regulatory compliance, and system design. Refrigerant sensing is becoming a critical component of leak detection and mitigation strategies for next-generation HVAC/R platforms. This white paper explores the environmental and regulatory factors driving the transition, the evolution of refrigerants, and the growing importance of refrigerant sensing technologies. It also examines sensor performance considerations, including detection accuracy, response time, environmental robustness, and long-term reliability, and provides an example of an A2L refrigerant sensor implementation.
