家用冰箱压缩机能耗增大和制冷量波动的原因之一是压缩机阀片不完善。减小阀片舌簧部刚度,可以减小阀片开启所需的压差△P以及压缩机消耗的功率,同时可增大冷量。但是减小吸气阀片舌簧部刚度,会导致气阀关闭滞后,造成制冷剂泄漏,使制冷量的增大变得微不足道。 Household refrigerator compressor energy consumption and cooling capacity fluctuations is one of the reasons compressor valve imperfections. Reducing the stiffness of the valve disc reed section reduces the pressure differential ΔP required for valve opening and the power consumed by the compressor while increasing the cooling capacity. However, reducing the rigidity of the reed valve portion of the suction valve causes the valve to close and lag, resulting in the leakage of the refrigerant, which makes the increase of the cooling capacity negligible.
