Rotary-heat exchanger which have three functions as a blower, a heat exchanger and a pump have been developed on the basis of a cross flow fan. In the first paper, the blower and pump performances of the rotary-heat exchanger were clarified. In the present paper, we report the heat transfer characteristics of it as a heater and a cooler. The experiments as a heater have been done using with several kinds of rotors that differ in shape. As a consequence, the experimental relation between the heat transfer coefficients and the parameters of the rotary-heat exchanger was obtained. And in the experiments as a cooler, it is clarified that the heat transfer coefficient is higher than that of a heater. In particular, condensed water droplets on the blades of rotor which are heat transfer surfaces are rapidly and continually blown off by the centrifugal force.
