This study investigated methods for improving the performance of heat exchangers for use in the hot-water supply side of a heat-pump-type water heater system.The pressure drop and heat transfer characteristics inside the coiled flow channel of corrugated tubes in laminar and turbulent flow regions were experimentally investigated.Four corrugated copper tubes with an outside diameter of 12.7 mm and coiled diameters of 100,120,140,and 180 mm were used in this experiment.
