[background technology]
At present, solar water heater only is used widely aspect domestic water, people's heating in the winter time generally adopt electricity, combustion gas, coal as thermal source, reach the purpose of heating by radiator or tubular type floor heating, this device will consume a large amount of electric energy or a large amount of coal or natural gases in water heating process, not only cost is higher for it, and can strengthen environmental pollution.Some also having occurred on the market now utilizes solar energy to carry out the indoor heating device, but these devices exist the defective that can not keep continuing the constant temperature heat supply more, especially at sunshine inadequate the time, its water temperature does not reach people's requirement of living at all, says nothing of and has carried out heating of house.
[summary of the invention]
Defective in the objective of the invention is to use at above technology, and openly provide a kind of simple in structure, energy-conservation, safe, and can keep the solar heating system of lasting constant temperature heat supply.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is as follows: a kind of solar heating system, it is by storage tank, electric heater unit, solar energy heat collection pipe, water purification installation, circulating pump, outlet pipe, the heat radiation heating installation, water inlet pipe, inductor, magnetic valve, automation system controller constitutes, described solar energy heat collection pipe is connected setting with storage tank, storage tank is provided with steam vent, inside is provided with electric heater unit, simultaneously, storage tank also is connected with inductor, storage tank is connected with the heat radiation heating installation with circulating pump through water purification installation by water pipe, and the heat radiation heating installation is connected with storage tank by another backflow water pipe, form a water circulation, article two, be respectively arranged with water inlet pipe and outlet pipe on the water pipe, water inlet pipe is provided with magnetic valve, magnetic valve is connected with automation system controller by circuit, simultaneously, described automation system controller also is connected with circulating pump by circuit, electric heater unit and inductor.
In concrete the use, when the water level in the storage tank was lower than designated water level, automation system controller started the magnetic valve automatic loading water, makes cold water enter storage tank via water inlet pipe, finishes water on the water tank.When automation system controller senses that water temperature reaches design temperature in the storage tank, circulating pump starts automatically starts working, water by storage tank by water pipe respectively via sending into the heat radiation heating installation behind water purification installation and the circulating pump, water pipe is provided with outlet pipe, and outlet pipe can be discharged life hot water.Like this, not only can reach the effect of indoor heating, and not influence life hot water again.Simultaneously, the water that enters the heat radiation heating installation enters storage tank by another backflow water pipe again, form a water circulation, if when water temperature is lower than design temperature in circulation engineering, automation system controller starts electric heater unit makes water temperature rise to design temperature.
Beneficial effect: the utility model adopts solar energy and electrical heating to combine, and not only simple in structure, energy-conservation, safety, environmental protection, and full intellectualized operation can guarantee lasting constant temperature heat supply in 24 hours.
[specific embodiment]
As shown in the figure, a kind of solar heating system, it is by storage tank 1, electric heater unit 2, solar energy heat collection pipe 3, water purification installation 4, circulating pump 5, outlet pipe 6, heat radiation heating installation 7, water inlet pipe 8, inductor 9, magnetic valve 11, automation system controller 12 constitutes, described solar energy heat collection pipe 3 is connected setting with storage tank 1, storage tank 1 is provided with steam vent 10, storage tank 1 inside is provided with electric heater unit 2, simultaneously, be connected with inductor 9 on the storage tank 1, storage tank 1 is connected with heat radiation heating installation 7 with circulating pump 5 through water purification installation 4 by water pipe, and heat radiation heating installation 7 is connected with storage tank 1 by another backflow water pipe, form a water circulation, article two, be respectively arranged with water inlet pipe 8 on the water pipe, outlet pipe 6, water inlet pipe 8 is provided with magnetic valve 11, magnetic valve 11 is connected with automation system controller 12 by circuit, simultaneously, described automation system controller 12 also is connected with circulating pump 5 by circuit, electric heater unit 2 and inductor 9.
