The latent heat recovery type heat exchanger is one of the effective methods in order to improve thermal efficiency by recovering latent heat. This paper described that the heat transfer and pressure loss characteristics of the latent heat recovery type heat exchanger having straight fin (fin length : 65mm or 100mm, fin pitch : 2.5mm or 4mm) were clarified by measuring the exchange heat quantity, the pressure loss of heat exchanger, and the heat transfer coefficient between outer fin surface and gas, and that the effects of fin length and fin pitch on heat transfer and pressure loss characteristics were clarified. Furthermore the equations for predicting the heat transfer coefficient and pressure loss which are necessary on design of the heat exchanger were proposed.
