【Abstract】 in this paper, the leakage process in a tank with a nonazeotropic mixture hasbeen analysed theoretically. The effects of vapour and liquid leakage on the concentration in thetank have been discussed under various conditions. The simulation shows that the effect of vapourleakage on the concentration is much greater than liquid leakage and increases obviously as thetemperature of the tank goes down. But the relationship between the vapour leakage fraction andtank concentration does not change remarkably at different initial charges. Only using some nearazeotropic mixtures, the concentration in the tank seems unchanged during the process of vapourleakage. It is certain that this investigation is of value in studying leakage of refrigeration or heatpump systems and finding a simple way to charge the systems with refrigerant mixtures.更多还原
