【摘要】 混合工质的充灌或泄漏都可能造成制冷空调系统中工质组分浓度发生变化,影响系统性能。本文研究了R407系列混合工质组分浓度变化的特性,获得了组分浓度变化的特征线,并研究了当组分浓度沿特征线变化时,制冷空调系统循环性能的变化规律,可用于指导采用R407工质的系统设计。更多还原

【Abstract】 Charge and leak processes of zeotropic refrigerant can cause the change of mixture concentration in refrigerant systems and affect the system performance. The concentration change character of R407A/B/C/D was investigated and the concentration characteristic line was obtained. The performance change of refrigerant systems along the characteristic line was analyzed.更多还原
