Abstract: A novel evaporator with a vapor-liquid separation is proposed. It can control quality of refrigerants by vapor-liquid separation that is accomplished by the baffle with small holes in the heads. A steady model of the vapor-liquid separation evaporator is established. The calculated heat transfer coefficient and pressure drop are verified by experiments with errors within ±30%. The effect of tube arrangements on the thermodynamic performance of the evaporator is analyzed by this program. The results show that the effect is significant.

Key words: vapor-liquid separation evaporator, tube pass scheme, heat transfer coefficient, pressure drop
