DETECTION OF MOISTURE IN REFRIGERANTS |
摘要 |
Moisture can be detected in a refrigerant background such as HFC (Hydroflurocarbon) HFC-134A and HFC-152A and exampled by HFC-23, HFC-32, HFC-143A, HFC-125, HFC-245FA, HFC-227EA, and the like. The system can include a light source operating at any one of several wavelengths within the water absorption bands at wavelengths such as 1.4, 1.9 and 2.7 µm and a detector that measures the transmitted light intensity through the HFC samples. In one variation, the light source is a tunable diode laser and the moisture level is determined by direct absorption and harmonic spectroscopy. Related techniques, apparatus, systems, and articles are also described. |
