Research on Constant Temperature Control System for Hot Water

Abstract:

In view of the present that this defect of water heater shower valve of the water temperature does not direct the user to the water temperature and can't maintain a constant outlet water temperature for long time, innovating a new type of water temperature control device. The adjusting device used the system of single chip microcomputer STC89C52 as the core, real-time water temperature and hot and cold water temperature were collected by digital temperature sensor DS18B20, adjusted with PID control method, drive motor drive the angle of opening and closing of the blade in mechanism device, to change the water volume of the hot and cold water. the purpose of keeping water temperature gain on the users required temperature and keeping constant temperature, through data experiment shows that the adjustment system structure is simple, running accurate effective and adjusting the steady and fast.
