The specific embodiment
The specific embodiment of the technical scheme of accompanying drawings the utility model; As shown in Figure 1; The solar water heating system that photovoltaic and photo-thermal combine comprises that flat-plate solar collector 2, water tank 3, straightway pump 5, flat-plate solar collector 2 medium inlets and straightway pump 5 are connected through pipeline, and flat-plate solar collector 2 media outlets and water tank 3 are connected through pipeline; Straightway pump 5 is connected with water tank 3 interior coil pipes; There is temperature sensor 7 at 2 media outlet places at flat-plate solar collector, in water tank 3 upper and lowers temperature sensor 8 and 9 are arranged respectively, and straightway pump 5, temperature sensor 7,8,9 are connected with controller 4 respectively; Also comprise solar panel 1, solar panel 1 is connected with controller 4.Described straightway pump 5 is through controller 4 power supplies, and controller 4 power supplys are provided by solar panel 1.Water tank 3 and user side pump 11 are connected through pipeline, also have a temperature sensor 10 in 11 outlets of user side pump, and sensor 10, user side pump 11 are connected with controller 4 respectively, and user's pump 11 is supplied power by controller 4.
Also include a battery 6, battery 6 is connected with controller 4.
Solar panel 1 provides the input power supply for controller 4, and controller 4 has the LCD display interface.
As shown in Figure 2, the input of controller 4 should be a wide region, is main with the characteristic that can adapt to solar panel 1.The type selecting of solar panel 1 can decide according to bearing power size and actual condition.The PV interface of controller 4 is the solar panel input, and the branch of both positive and negative polarity is arranged, and S1, S2, S3, S4 are DC output end, and controller 4 also has temperature sensor interface, is connected with the temperature sensor of this system.
The lead-out terminal S1 of controller 4, S2 are output as direct current, and voltage is 12V, and lead-out terminal S1, S2 are connected with user side pump 11 with straightway pump 5, for the pump power supply, also have the lead-out terminal S3, the S4 that reserve, can be other dc electric apparatus power supplies.Straightway pump 5 is to adopt dc brushless motor, has MPPT (maximum power point tracking), can constantly adjust peak power of output with the power of sunlight and give DC water pump, and straightway pump 5 is 8-24V wide region operating voltages.User side pump 11 also is a straightway pump.
The operation principle of the solar water heating system that this photovoltaic and photothermal combines is: when sunlight began according to solarization, cold medium temperature slowly raise in the flat-plate solar collector 2, and solar panel 1 can provide power supply to controller 4 simultaneously; When intelligent controller detects between flat-plate solar collector 2 temperature T 1 and the water tank temperature of lower T2 when existing one to open the temperature difference, this temperature difference can be provided with, for example T1-T2=Δ T '=10 °; This value can be regulated through the LCD panel button; Controller 4 is just given S1 terminal output 12V direct current, and straightway pump 5 is just started working, and arrives flat-plate solar collector 2 to cold medium transport in the coil pipe of water tank 3; Thermal medium in the flat-plate solar collector 2 is transported in water tank 3 coil pipes through the driving of DC water pump 5 again; Thermal medium in water tank 3 coil pipes again through coil pipe the cold water of exchange heat in the water tank 3, the cold water water temperatures heat absorption in the water tank 3 and rising, the medium heat release in the coil pipe and temperature descends; The temperature that detects T1 and T2 when controller 4 is during near some difference DELTA T ' '; For example T1-T2=Δ T ' '=4 are spent, and this value can be regulated through the LCD panel button, and controller 4 just cuts off the out-put supply of DC water pump 5; Water pump just quits work, and has so just accomplished first circulation.Flat-plate solar collector 2 continues to receive sun lights and shines; Inner medium temperature continues to rise; When the T2 in medium temperature T1 in controller 4 detects flat-plate solar collector 2 and the water tank 3 reached the unlatching temperature difference of setting, intelligent controller 4 was connected the power supply of straightway pump 5 once more, began the circulation of heat exchange for the second time this moment; Go round and begin again, the water temperature in the water tank 3 just progressively rises to the temperature of setting.Simultaneously on controller 4, connect a battery 6 again, can save the electric energy of solar panel 1 subsequent use.
