变频涡旋压缩机噪声特性及降噪方法研究
Research on noise characteristics and suppression methods of variable frequency scroll compressor
摘要
Abstract
In order to solve the problem of excessive noise of variable frequency scroll compressor,the noise characteristics of scroll compressor under different working conditions and speed were studied in detail.In the full anechoic chamber,the noise acquisition system is used to test the noise characteristics of the compressor under different working conditions and speed,and it is found that the scroll compressor has additional noise under the medium speed(70 rps),and the noise is mainly from the exhaust valve mechanism.On this basis,the exhaust valve mechanism is optimized,and the disc exhaust valve is used instead of the reed valve to reduce the extra noise caused by the reverse movement of the valve to slap the valve seat.The research results show that compared with the reed exhaust valve,the total sound pressure level of 30,70 and 110 rps under medium temperature conditions decreases by 0.99,3.83 and 1.82 dB respectively,while the total sound pressure level of 30,70 and 110 rps under low temperature conditions decreases by 1.42,4.15 and 1.98 dB successively.The research results will provide theoretical and technical support for the design of inverter scroll compressor with low noise.关键词
