The solar water heater has become Chinas renewable energy market demand is one of the largest and most rapid product development. However, most of the solar energy water heater control system on the market at present is single function, complex operation, it is not convenient to control the problem, a lot of controller with functions of temperature and water level show, only and the error is bigger. The main existing problems are the following two aspects: (1) does not have temperature control function. When due to weather or climate and light intensity is insufficient, the solar energy water heater will reach bath temperature requirements, to inconvenience water heater water heater users. Even if part of the solar water heater with auxiliary heating function, and is usually used in electric heating mode. And traditional electric heating temperature control heating unipolarity, big inertia, big lag and time-varying characteristics, application of the traditional analog control method, it is difficult to achieve ideal control effect. May also be the result of the heating time cannot control burnt, thus wasting electricity. (2) water control usually USES the manual control, water is not easy to find, cause the waste of water resources. Or a so-called water level control, is done by setting the solar water heater tank water when the function of automatic filling water, the water is full automatic water supply. Current control scheme is much by water level sensor based on lack of water or with water of different signal control on-off of semiconductor devices, thus further control the opening and closing state of the relay, solenoid valve, or not to water. This scheme is easy to cause the loss of the user in the process of using water filling water, mix water problems. For home users, a day in the use of hot water is not a great difference, if at any time when using filling water, mix water and then need to add complementary heat. So for manual control and mid-range solar water heater, we aim to use the control of water level sensor to develop a more intelligent, more economic and automatic water control system of the solar water heater. The system has the following advantages: you can set up time, external extension ability strong, easy to use, short development cycle, lower development costs. Meet the requirements of economy, practicality, scientific.
