Paper Abstract

The solar water heater has advantages of low cost, no pollution, safety, energy conservation and is very suitable for users in rural area. But many now used solar water heater has no alarm device resulting water and resource wasting because of forgetting to turn off the valve after water sailing upstream. To overcome this defect, an intelligent annunciator for solar water heater installed at the end of the return pipe is presented and designed in order to remind the user. Firstly, the advantages and disadvantages of automatic and manual sailing upstream are compared concluding that manual sailing upstream is more trustiness. Then an annunciator for solar water heater is studied and ameliorated. Its principle, parameters index and functions are introduced. The annunciator uses CD4069 chip as the core circuit with very little assistant circuit. It can provide sound and light alarm at the same time. This annunciator for solar water heater water is very simple in production, low cost, the use of safe and convenient. The annunciator is applicable to all solar power products, including various types of early installation of solar power water heaters and water tanks without changing their structures. It can meet family and industrial environmental applications.
