  • Patent number: 8070355
    Abstract: Disclosed are a method of detecting a leak of fluoroolefin compositions and sensors used therefor. In particular, the method is particularly useful for detecting a leak of a fluoroolefin refrigerant composition from a cooling system of an automotive vehicle. Such fluoroolefin refrigerant compositions have double bond structures which make them particularly well suited with sensing technologies, including: infrared sensors, UV sensors, NIR sensors, ion mobility or plasma chromatographs, gas chromatography, refractometry, mass spectroscopy, high temperature thick film sensors, thin film field effect sensors, pellistor sensors, Taguchi sensors and quartz microbalance sensors.

  • Patent number: 8058070
    Abstract: Disclosed are a method of determining the components of a fluoroolefin composition, a method of recharging a fluid system in which the composition is used, and sensors used therefor. In particular, the composition may be a fluoroolefin refrigerant composition used within a vapor compression system, where the refrigerant composition is useful in cooling systems as replacements for existing refrigerants with higher global warming potential. Such fluoroolefin refrigerant compositions have double bond structures which make them particularly well suited with sensing technologies, including: infrared sensors, UV/vis sensors, NIR sensors, ion mobility or plasma chromatographs, gas chromatography, refractometry, mass spectroscopy, high temperature thick film sensors, thin film field effect sensors, pellistor sensors, Taguchi sensors and quartz microbalance sensors.
