Description
(1) technical field
The present invention relates to a kind of solar water heater, the defroster of the solar water heater that particularly a kind of suitable freezed in winter area and extremely frigid zones use.
(2) background technology
Prior solar water heater, area in the winter time freezes, extremely frigid zones particularly, under the low situation of environment temperature, the solar energy heating components and parts are even the all-glass vacuum thermal-collecting tube of vacuum thermal insulation also can bursting by freezing, inner water tank can be out of shape by freezing and expansion, even spalling, the upper and lower water pipe of water tank can freeze to stop up, and not only bursting by freezing can not be used, and the thawing season in next year also can't use, unless annual overhaul and change parts.Though and existing separated type solar water heater has avoided water tank in outdoor situation of easily freezing, but still can't resolve the antifreeze problem of solar energy heating components and parts.
In addition on energy-conservation angle, general water heater is when low light photograph, the unglazed photograph, solar thermal collector itself will produce heat waste, and behind the unglazed photograph, the water temperature in the solar thermal collector will descend significantly, when supplying water heating once more, the heating water temperature starting point of solar thermal collector needs when solar irradiation intensity is up to standard, with the water water temperature after the cooling in the heat collector is the heating starting point, so electricity was added heat power consumption and increased greatly winter, had improved the production cost and the operating cost of solar water heater.
(3) summary of the invention
The object of the present invention is to provide the light-operated hot water backflow of a kind of solar thermal collector, supplementary heating water source, realize the defroster of the solar water heater of solar thermal collector freezing prevention protection.
The object of the present invention is achieved like this: it comprises central control circuit, temperature sensor, level sensor, light sensor, water flow switch, water pump, electrically-controlled valve and control panel, wherein temperature sensor, level sensor, light sensor and water flow switch are connected central control circuit by cable, and central control circuit connects water pump, electrically-controlled valve and control panel by cable.
When realizing purpose, the present invention also has some architectural features like this:
1, electrically-controlled valve links to each other with water pump, water flow switch, all is arranged in the water-heater water tank.
2, control panel is arranged on the water-heater water tank surface, and keyboard unit and display unit are arranged on the control panel.
3, temperature sensor, level sensor are separately positioned in water-heater water tank and the heat collector.
4, light sensor is arranged on the heat collector.
The water of solar thermal collector when solar irradiation is not enough, is given central control circuit by the light sensor number of delivering a letter by the intensity of illumination control of the sun among the present invention, and the hot water in the control solar thermal collector is back in the indoor water tank of solar water heater automatically; And low light according to the time do not have water in the solar thermal collector, when solar irradiation reaches solar thermal collector thermal-arrest standard, make the water storage of central control circuit control room inner water tank pump into solar thermal collector automatically by water pump by light sensor, solar thermal collector serves as that the heating starting point is started working with the water temperature that charges into water.
Useful effect of the present invention has:
1, winter successive cloudy days, prevent that solar thermal collector from freezing damage.
2, low light according to, unglazed according to the time, reduce the heat waste of solar thermal collector itself.
When 3, solar thermal collector supplies water heating once more, the heating water temperature starting point of solar thermal collector improves (if the water in the solar thermal collector can not reflux, behind the unglazed photograph, water temperature in the solar thermal collector will descend significantly, when solar irradiation intensity is up to standard, solar thermal collector will be the heating starting point with the water water temperature after the cooling in the heat collector), save heat time heating time and the electric power consumption of mending.
4, because the present invention has " solar thermal collector freezing prevention " function, so do not need solar thermal collector self to have antifreeze function again, therefore the specification requirement to solar thermal collector reduces greatly, thereby has reduced the disposable input cost of producing solar water heater;
5, because indoor water tank is communicated with the water pipe of solar thermal collector when low light shines (low temperature), do not have water in the pipe,, reduced solar water heater day-to-day operation in winter expense so should not need winter communicating pipe to add the ribbon heater heating and anti-freezing.
6, when running water is cut off the water for a long time, the water between solar thermal collector and water tank and heat collector in communicating pipe all with reflux tank, can provide emergent and uses (water in all solar thermal collectors all can not reflux automatically use) at present.
Some of the above hot water backflow functionality of the defroster of solar water heater of the present invention acts on, and strengthened the function of use of solar water heater, improved the thermal efficiency of solar water heater, reduced the production cost and the operating cost of solar water heater effectively.
