Abstract

This study investigates the impact of changing mounting types on the vibration characteristics of a 1 HP split-unit air conditioning compressor. Excessive vibration in compressors can lead to reduced efficiency, increased noise, and premature component failure, emphasizing the importance of effective vibration management. Experiments were conducted using three mounting types: the original rubber mount, a newly designed rubber mount, and a shock absorption spring head mount. Vibration levels were measured at two critical locations near the mounting base and the copper pipe connection using high-precision sensors. The results showed significant differences in vibration isolation capabilities among the mounts. The original rubber mount exhibited the highest vibration levels, while the new rubber mount reduced vibration by 40-45%. The shock absorption spring head mount demonstrated the best performance, achieving reductions of over 64%. Both the new rubber and spring head mounts complied with ISO 10816 standards for vibration severity, ensuring reliable and efficient operation. This research highlights the practical benefits of using improved mounting systems to enhance compressor performance and longevity. While the shock absorption spring head mount provided the most effective vibration isolation, the new rubber mount offered a cost effective alternative. The findings provide valuable insights for designing and maintaining air conditioning systems, contributing to advancements in vibration management technologies. Future work should explore broader applications, real world testing, and innovative materials for mounting systems to further improve performance.
