Abstract
The utility model provides a cold water eliminating and defreezing system of a solar water heater pipeline, comprising a pipeline water-temperature sensor, a solar hot water tank, a heater, a hot water tank water-temperature sensor, a water pump, a water flow switch, a control box, a hot water outlet pipe, an electric valve and a cold water pipe. In the utility model, a single chip microcomputer is adopted to control the system, and the cold water in the pipeline can be eliminated through timely heating and circulation on the water in the system, therefore, not only the water is convenient in use, but also the water resource is saved, and the freezing of the water is prevented.
Description
Technical field
The utility model relates to a kind of solar energy hot water supply system, especially a kind of solar water heater that is used for uses the system of getting rid of ducted cold water and preventing freezing pipeline of low temperature and solar water heater, and promptly usually said solar energy water heater pipe cold water is got rid of and winterization system.
Background technology
In solar energy hot water supply system, because of the pipeline inner product has cold water, freeze easily when not only it is cold during use, and in use want will just have hot water to flow out after these cold water eliminatings earlier, both waste water resource was made troubles to the user again.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cold water that can get rid of in the solar water heating system, makes the user in time use hot water, the conserve water resource, and what can prevent again that cold from causing freezes, and avoids solar energy heat distribution system to damage because of freezing.
For addressing the above problem, this solar energy water heater pipe cold water is got rid of and winterization system comprises pipeline cooling-water temperature sensor, solar energy hot water tank, heater, boiler cooling-water temperature sensor, water pump, water flow switch, control box, hot water outlet pipe, electrically operated valve, cold water pipe.Its improvement is: water pump one end is connected with solar energy hot water tank, the other end is connected with pipeline cooling-water temperature sensor, electrically operated valve, water flow switch, the pipeline cooling-water temperature sensor other end is connected with solar energy hot water tank, the electrically operated valve other end is connected with cold water pipe, the water flow switch other end is connected with the hot water outlet pipe, heater, boiler cooling-water temperature sensor are connected with boiler respectively, and pipeline cooling-water temperature sensor, heater, boiler cooling-water temperature sensor, water pump, water flow switch, electrically operated valve are connected with control box by lead.
As further improvement of the utility model, in the described control box electronic circuit board is housed.
After adopting this scheme, formed water circulation system at pipeline cooling-water temperature sensor, solar energy hot water tank, pump house, electronic circuit is controlled system according to preset program, when the hot water outlet pipe there are flowing out, system will the basis that water temperature compares in to water tank and pipeline on, open in good time or switch off the pump, by the circulation of water, cold water in the pipeline is entered solar energy hot water tank, make the user in time use hot water; When water temperature was lower than uniform temperature in the solar energy hot water tank, system can heat to the water in the solar energy hot water tank by heater automatically, freezes preventing; When the water in the pipeline is lower than uniform temperature, system will open water pump the cold water in the water pipe will be entered solar water container, freeze to prevent the water in the pipeline.
Description of drawings
Below in conjunction with accompanying drawing the utility model specific embodiment is described in further detail.
Fig. 1 is that a kind of solar energy water heater pipe cold water of the present utility model is got rid of and the winterization system schematic diagram.
The specific embodiment
By a kind of solar energy water heater pipe cold water shown in Fig. 1 get rid of and the winterization system schematic diagram as can be seen, native system comprises pipeline cooling-water temperature sensor 1, solar energy hot water tank 2, heater 3, boiler cooling-water temperature sensor 4, water pump 5, water flow switch 6, control box 7, hot water outlet pipe 8, electrically operated valve 9, cold water pipe 10.Described water pump 5 one ends are connected with solar energy hot water tank 2, the other end is connected with pipeline cooling-water temperature sensor 1, electrically operated valve 9, water flow switch 6, pipeline cooling-water temperature sensor 1 other end is connected with solar energy hot water tank 2, electrically operated valve 9 other ends are connected with cold water pipe 10, water flow switch 6 other ends are connected with hot water outlet pipe 8, heater 3, boiler cooling-water temperature sensor 4 are connected with solar energy hot water tank 2 respectively, and pipeline cooling-water temperature sensor 1, heater 3, boiler cooling-water temperature sensor 4, water pump 5, water flow switch 6, electrically operated valve 9 are connected with control box by lead.
Referring to Fig. 1, in the control box 7 of native system electronic circuit board is housed.
Control circuit of the present utility model is made up of single-chip microcomputer, power circuit, temperature sensing circuit, water pump control circuit.Single-chip microcomputer is controlled system according to the program of input in advance, and power circuit converts civil power to dc source and powers to system; Temperature sensing circuit is made up of temperature sensor; Water pump control circuit is made up of FET, resistance.
After system powers on, when hot water outlet pipe 8 there are flowing out, water flow switch 6 is passed to single-chip microcomputer with signal, be divided into two kinds of situations this moment: a kind of is if the temperature basically identical at boiler cooling-water temperature sensor 4 and pipeline cooling-water temperature sensor 1 place, or the temperature at boiler cooling-water temperature sensor 4 places is when being lower than the temperature at pipeline cooling-water temperature sensor 1 place, and water pump 5 is not worked; Another kind is if the temperature at boiler cooling-water temperature sensor 4 places is when being higher than the temperature at pipeline cooling-water temperature sensor 1 place, water pump 5 work, cold water in the pipeline is entered solar energy hot water tank 2, to the temperature at boiler cooling-water temperature sensor 4 places when identical with the temperature at pipeline cooling-water temperature sensor 1 place substantially, water pump 5 quits work, and makes the user in time use hot water.When the water temperature in the solar energy hot water tank 2 was lower than uniform temperature, system can heat by the water in 3 pairs of water tanks of heater automatically, freezes preventing; When the water in the pipeline is lower than uniform temperature, system will start water pump 5 cold water in the water pipe will be entered solar energy hot water tank 2, freeze to prevent the water in the pipeline.Open electrically operated valve 9, running water can be by cold water pipe 10 to the Jia Shui of system.If outlet pipe and 2 of solar energy hot water tanks at native system water pump 5 insert electrically operated valve, native system can also be realized adding water from the trend water tank, and increases hot water effluent's pressure by water pump.Native system also can be synthesized together with the solar water-temperature water-level display system.
