Method for determining category of insulating medium or for determining blowing agent in insulating medium for disposal or recycling of refrigerators, involves determining presence of blowing agent of category in sample gas by sensor

摘要

The method involves determining a presence of a blowing agent of a category in a sample gas (28) by a sensor (06). The presence of blowing agent of another category in the sample gas is determined by another sensor (07). The blowing agent of the former category has chlorofluoro hydrocarbon and hydrofluorocarbon. The blowing agent of the latter category has pentane, particularly cyclopentane. The presence of the blowing agent or an insulating medium (02) of one category is determined due to a signal of the former sensor and a signal of the latter signal. An independent claim is included for a device for determining a category of an insulating medium or for determining a blowing agent in the insulating medium.
