Summary

From the viewpoint of global warming prevention, it is becoming increasingly important to detect and repair leaks of fluorinated refrigerants from refrigeration and air-conditioning equipment as quickly as possible. In order to solve this problem, a technology to detect and identify leaks quickly with fewer man-hours was studied, and a remote detection technology using infrared absorption of gas was focused on.
In this study, the absorption wavelengths of currently used HFC refrigerants were researched, and it was found that R-32, which has a relatively simple molecular structure, is an easy refrigerant to measure for reflective infrared laser absorption spectroscopy measurements. And, considering that R-32 and its mixed refrigerants are used around the world among various fluorocarbon refrigerants, a remote detection device for R-32 gas was developed and successfully detected.
