It thought about the action of the bubbles in hot water as a corrosion factor of the erosion corrosion generated in copper hot water piping systems of building equipment. It investigated concerning of the copper hot water piping systems of building equipment, and the career of the erosion corrosion generation, and the dissolved oxygen concentration and the states of white cloudiness with the hot water. The loop circulation equipment that simulated the hot water piping systems of building equipment was constructed. The generation condition of the bubble in hot water was examined. As a result, the generation of the erosion corrosion was clarified to the closed copper hot water piping systems of building equipment and it was clarified of the generation of the bubble on the downstream side etc. of the valve by use of hot water.
