Description
Technical field
The present invention relates to technical field of solar water heaters, specifically a kind of water tank free sun that can be automatically replenished
The control system of energy water heater.
Background technology
Water tank free solar water heater utilizes power PC M phase-change materials, and will by concentric locking collar tubular type parallel-connection structure
Energy-accumulation material is inserted in solar energy heat collection pipe, the storage in place after solar energy heat collection pipe thermal-arrest is realized, with " PCM phase-changing energy-storings
Material " substitutes the solar water heating system using " water " as heat storage medium, realizes cistern free, the module of solar water heater
Change.Water tank free solar water appliance has the advantages that the thermal efficiency is high, thermal starting is fast, therefore is widely used.
What water tank free solar water heater used at present is usually the thermal-collecting tube done by the big pipe glass of ultrahard carbon silicon, and
Thermal-collecting tube also serves as water tank use, and therebetween, overpressure is normal pressure for daily non-bathing.Therefore, it is warm in thermal-collecting tube when solar radiation
Degree rise, a part of water vapor, raises thermal-arrest overpressure, drains so as to which part water be extruded from the overfall of thermal-collecting tube.
If continuous more days fine days, and user use water heater, it is possible to the thermal-collecting tube at the top of making becomes blank pipe, and such one
Come, not only the actual use capacity of water heater can greatly reduce than rated capacity, and if user again just in the sun very
Using water heater when processing strong, temperature can reach and be spent 200 more at this moment emptying thermal-collecting tube, once there is water entrance, it is possible to go out
Existing booster phenomenon.
The content of the invention
The present invention proposes a kind of control system for the water tank free solar water heater that can be automatically replenished, and can make heat collector

When opening spray head bathing, the pressure in hot-water line declines, and pressure sensor detects this signal, signal is passed
Controller is transported to, controller controls normally opened bidirectional electromagnetic valve to close, and hot-water heating system is formed a closed-system, at the same time often
Powered-down magnet valve is opened, and cold water enters thermal-arrest by pressure itself in running water pipe by filter, pressure-reducing valve, Chang Guan electricity magnet valves
Device, hot water in heat collector is set along hot water tube top to shower nozzle, to form hot water bathing.When bathing finishes, spray head, system are closed
Interior pressure can raise rapidly, and when being increased to threshold value, pressure sensor can transmit the signal detected to controller, controller
Closed electromagnetic valve is often closed in control, cuts off tap water supply, while controls normally opened bidirectional electromagnetic valve to open, the pressure meeting in heat collector
Through this valve pressure release to normal pressure, the water released enters water storage box.Heat collector is daily to be at atmospheric pressure state, when sunny, collection
Temperature gradually rises in heat pipe, part water vapor, causes overpressure microlitre, and part water can be along cold water pipe adverse current, through branch
Pipe is left in water storage box, and same day idle running is cloudy or during evening, and the vapor of vaporization can return to the state of water, the pressure in heat collector
Power can reduce, or even negative pressure occur, now spill into the water of water storage box and can flow back to automatically in heat collector, go round and begin again, and be formed certainly
Dynamic moisturizing.The present invention can be automatically replenished heat collector, ensure that the actual capacity of heat collector will not be less and less, avoid water
The waste of resource, thermal-collecting tube will not also form blank pipe, avoid the generation of booster phenomenon.
As preferable technical scheme, the tie point of mixed water pipe and cold water pipe be arranged on pressure-reducing valve and normal powered-down magnet valve it
Between.
As preferable technical scheme, safe mouth, an end of the safe mouth and safety valve are set on the water storage box
Mouth connection, another port of safety valve is connected with hot-water line.
As preferable technical scheme, overfall is also set up on water storage box.Overfall can make heat collector and water storage box with it is outer
Boundary communicates, and keeps normal pressure, and can discharge water excessive in water storage box, avoids building the pressure；The presence of safety valve is played to system
The effect of protection, when related device damages in system, by safety valve pressure release when causing system internal pressure too high, it has been effectively ensured and is
The safety and stability of system.
By adopting the above-described technical solution, the present invention has beneficial effect following prominent：
Heat collector of the present invention is daily to be at atmospheric pressure state, and when sunny, temperature gradually rises in thermal-collecting tube, part
Water vapor, causes overpressure microlitre, and part water can be left in water storage box, same day idle running along cold water pipe adverse current through branched pipe
During cloudy or evening, the vapor of vaporization can return to the state of water, and the pressure in heat collector can reduce, or even negative pressure occur,
Now spilling into the water of water storage box can flow back in heat collector automatically, form heat collector automatic water supplement；It ensure that the reality of heat collector
Capacity will not be less and less, avoids the waste of water resource；Thermal-collecting tube will not form blank pipe, avoid the generation of booster phenomenon.
