In view of the shortcoming of traditional solar water heater with water wasting and incon-venient to use in winter,the emptying anti-freezing and water-saving intelligent control system is de-signed for traditional solar water heater.This intelligent temperature control system takes AT89S52 mi-crocontroller as the core and utilizes the digital temperature sensor DS18B20,LCD and solenoid valve. This system has realized the functions of the pipeline emptying anti-freezing,water temperature,water level display.And the PID control can maintain a constant water temperature when bath.This system has good man-machine interactive features,in accordance with the requirements of the national energy con-servation and emissions reduction.
