The composition separation of R407C is used to improve performance of air conditioners and heat pump water heater units. Therefore, it is important to grasp a separation performance of a packed column rectifier and make a useful nondimensional equation of mass transfer coefficients for design of the rectifier. The experiments were carried out to investigate an influence of the vapor velocity on the separation performance, and an overall mass transfer coefficient of gas side was measured. The nondimensional equation for the mass transfer coefficients was made based on the measured data. The influence of the refrigerant charge and the packed height on the separation performance was evaluated with the experiments and calculated results with the equation. The calculated results agreed with the experimental results.
