Existing and upcoming regulations in regard to PFAS (per- and polyfluoroalkyl substances, also called “forever chemicals”) and F-gases (fluorinated greenhouse gases) are severely restricting the use of conventional synthetic refrigerants in air conditioning, heat pumps, and other HVAC systems. The natural refrigerant R290 is propane gas, which is considered to be a more sustainable alternative to conventional solutions. However, due to its high flammability, reliable and highly accurate leakage detection measures are required to ensure safe operation.
Senseair’s newly developed gas sensor Sunlight R290 employs the latest NDIR (non-dispersive infrared) technology, utilizing LED light sources and photodiode sensors. Due to its minimal heat generation, the sensor can be safely operated with R290. Additionally, due to the characteristics of the NDIR method, the detection is less affected by vibrations or interfering gases, enabling robust and reliable measurements that meet the stringent leak detection requirements of the IEC 60335-2-40 safety standard for electric heat pumps, sanitary hot water heat pumps, and air conditioners.
