Noise and cycle performance of a new damping valve for compressor.

Number: pap. 1135

Author(s) : HUANG B., YUAN H.

Summary

A new design of damping valve which contain two steel valve and one piece of silica gel is proposed in this paper. This new structure is considered effectively in the valve noise improvement especially in the mid-low speed which can lead the flutter response of valve. 6 case damping valves of different height are assembled in compressors. Noise and cycle performance experiments are carried out with the same working condition cases. One optimal damping valve is selected and its sound pressure level of compressor is gotten about 2dB improvement comparing with the traditional product in the mid-low speed as 3210rpm and 1380rpm. Meanwhile, cycle performance's result is at the same level with the traditional product.
