| 摘 要： | 文中从范德瓦尔状态方程导出了工质状态的气液相尖点突变机理.从自复叠循环低温节流阀的阀前工质状态入手,以自动复叠式循环的两个节流阀开度作为控制变量,分析了低温节流阀前工质状态的突变,进而针对自复叠试验中的突变现象进行了分析和解释.结果表明,随着自复叠循环的高温节流阀开度不断减小,低温节流阀前工质将由液相状态朝着气化突变方...

| Abstract: | The cusp-type catastrophe mechanism of gas-liquid state variation was deduced by Van der Wall equation.With the control parameters of throttle valves' opening,the refrigerant state catastrophe before low-temperature throttle valve in Auto-cascade refrigeration(ACR) system was analyzed,and the catastrophe phenomenon in ACR system experiments was analyzed and explained.The result shows that,with the decrement of high-temperature throttle valve's opening,the state of the refrigerant before low-temperature thro... |
