| Abstract: | From the market levels,cost estimation,reliability and etc.,this paper analyzes the feasibility on the PA66 spool instead of broach spool in the retaining valve using in air-conditioner. As the broach retaining valve is hard to process and costly,it is feasible that using the PA66 retaining valve in the new refrigerant R410a instead of broach. |
