Evolving Regulations for Refrigeration Systems
Since the 1950s, synthetic refrigerants have been widely used in cooling systems. While they are non-flammable and non-toxic, many contribute significantly to the greenhouse effect. International agreements, such as the Montreal Protocol and the F-Gas Regulation, aim to reduce the use of these climate-damaging substances.
Constantly changing regulations have led to an artificial shortage of refrigerants, causing significant price increases. As a result, new systems are now designed with refrigerant charges below 3 kilograms. Additionally, continuous monitoring of cooling systems is recommended, and the frequency of mandatory leak-tightness inspections has been significantly increased.
Precision Control with Axetris Infrared Sources
Axetris infrared sources cover the entire spectrum from 2 µm to 14 µm. Two key measurement principles utilize these sources: non-dispersive infrared spectroscopy (NDIR) and photoacoustic spectroscopy (PAS). While these methods have a higher initial cost compared to conventional sensor solutions, they offer a lifespan of over seven years, extended calibration intervals, and reduced maintenance efforts—leading to significantly lower operating costs.
