In recent years, the global refrigeration industry has increasingly adopted high-efficiency, low-GWP (Global Warming Potential) refrigerants; R32 and R410A have emerged as the mainstream choices for residential air conditioners, heat pumps, and commercial refrigeration equipment. Compared to traditional R22 systems, these next-generation refrigerants impose more rigorous demands regarding system operating pressures, compressor discharge temperatures, and thermal cycling conditions, thereby presenting new challenges for the reliability of piping connections and vibration-damping components.
