制冷系统四通阀动作有效性研究

Activation Effectiveness Study of Four-way Valve in Refrigeration System

四通阀为制冷系统中最常用的元器件之一,其动作的有效性直接影响到系统是否可以正常工作,但对四通阀动作的有效性和噪音的评价并没有太多的研究,实际应用中失效的情况时有发生。为此,本研究在保证低噪音的前提下,研究不同工况下四通阀换向所需的最小工作条件。

Four-way valve is one of the most common components in refrigeration system. The activation effectiveness directly impacts the normal work of whole system. However, there is inadequate study on its movement effectiveness and noise evaluation, which always leads to malfunctions in actual work. Therefore, this study assures the low noise as the precondition, aimed to study the minimum operation conditions the four-way valve needs to work in different conditions.
