Senseair To Showcase The S8 A2L Leak Detection Platform At AHR 2020

NAPERVILLE, Ill., Jan. 20, 2020 /PRNewswire/ -- The HVAC/R industries are currently using high Global Warming (GWP) refrigerant gas blends.  These blends made up 2% of all Greenhouse gasses in 2011 – projected by the EPA to increase by 64% in 2020 and by 139% by 2030.  This has driven the North American HVAC/R market to reevaluate a potential industry-wide shift to refrigerant blends with a lower Global Warming Potential (GWP).

Any potential refrigerant blend change must not only reduce the GWP of the refrigerant blend but also optimize the energy efficiency and life-cycle climate performance for the HVAC/R market to accept any potential cost impact of implementation.

R32 (difluoromethane) and R32-based refrigerant blends have been identified as the lead alternative refrigerant with the capability of reducing the global warming potential (GWP) of refrigerants in the HVAC/R market.  R32 and R32-based refrigerant blends have the potential to represent a 5% reduction in the HVAC/R demand on the power grid – $6b savings in power generation cost avoidance per the US Energy Information Administration while providing a zero-ozone depletion potential.

The unique challenge with R32 and R32-based refrigerant blends is that these gasses are mildly flammable per ISO 817:2014, and as such have an A2L classification that would require the HVAC/R systems to incorporate a gas leak monitoring and mitigation system according to UL 60335-2-40 Edition 3 Annex GG & LL.

Senseair S8 A2L Leak Detection Sensor Core is designed to ensure UL alignment in the areas of:

  • 15+ Years Expected Lifetime
  • Fast Response Time; < 10 Seconds
  • Measurement Accuracy
  • Long-term Measurement Stability
  • Autocalibration Algorithm for Maintenance Free Installation
  • No Measurement Impact due to Temperature or rH Changes
  • Immunity to poisoning
  • Selective to the gas being measured, no influence from "other" gases
