Latest A2L R32 Refrigerant Gas Sensor Communicates an Alert or Engages in Mitigation Procedures

Press Release Summary:

The A2L R32 Refrigerant Gas Sensor is designed for implementing leakage detection in refrigeration systems. The sensor targets R32 gas concentration in the A2L mixtures and calculates concentration of refrigerant gas and relates to avoidance thresholds by levels of Lower Flammability Limit.

Senseair Launches A2L R32 Refrigerant Gas Sensor At AHR 2019

ST. CHARLES, Ill., Jan. 7, 2019 /PRNewswire/ -- Refrigerant gases, a necessity for controlling thermal functions in refrigeration systems, typically fall under stringent regulations. Since the Montreal protocol in 1987, refrigerants like chlorofluorocarbons (CFCs) were the first to be banned. Today, the HVAC/R industry is undergoing its latest change to address the contribution to climate change.

This new change adds some drawbacks in the efforts to phase in refrigerants with low Global Warming Potential. Specifically, many of the new refrigerants being introduced fall within A2L classification, meaning that they are mildly flammable according to ISO 817:2014.

To overcome the concerns of the mild flammability, development of an A2L gas leakage detection sensor for mixtures containing R32 provides a solution for controlling mitigation systems and/or shutdowns.

Senseair, as a global leader in gas sensing technologies, has recently launched a robust and long-lifetime NDIR-based refrigerant sensors to implement leakage detection in refrigeration systems. Senseair targets the R32 gas concentration in the A2L mixtures and calculates the air volume concentration of the refrigerant gas and relates it to the avoidance thresholds by levels of Lower Flammability Limit. The sensing platform can then communicate an alert or directly engage in mitigation procedures.

Senseair offers their solutions either as a calibrated sensor module for integration by customer, or as a complete pre-integrated board design with relays and additional features bundled with all the required sensory aspects. Senseair can even design and manufacture the complete enclosed system for a product which is ready to install. To learn more about this new innovation, visit Senseair at the AHR EXPO January 14th – 16th in Atlanta, GA.
