摘要

A novel pre-compression system is proposed: a dual vibrating nozzle mechanism that utilizes the waste vibrations from an oil-free linear compressor body. The pre-compression performance of the proposed system was evaluated using both numerical simulations and experimental measurements. Phase differences were systematically varied from 0° to 360° in 45° increments, and three different dual vibrating nozzle models were tested. Performance was assessed by comparing suction valve displacement and the average suction mass flow rate for each model. The results demonstrate that the dual nozzle model with a 4–14.64 mm configuration and a 180° phase difference exhibited the best performance. Compared to the single vibrating nozzle, the dual nozzle model showed a significant improvement in pre-compression effectiveness. This improvement is directly associated with potential increases in the cooling capacity and energy efficiency ratio (EER) of the linear compressor. Future work will focus on integrating the dual vibrating nozzle system into real-world compressor hardware.
