Each door type central solar heating device
Technical field
The utility model relates to application of solar, specifically a kind of each door type central solar heating device.
Background technology
At present, the solar-heating device that uses in the residential quarter has two kinds: a kind of is family expenses separate unit solar water heater, and a solar water heater is installed on each comfortable roof of each household, and the outward appearance of building is had bigger influence, is unfavorable for the architecture-integral design.Another kind is centralized solar-heating device, is made up of heat collector, attemperater, assisted heating device, water circulating pump, pipe-line system and heat-insulation system.When weather was fine, heat collector absorbed solar energy optical-thermal and directly the water in the boiler is heated for use; Water in overcast and rainy need assisted heating device startup heat tracing water tank is for use.Like this, the operation of whole device needs a large amount of water, electricity consumption.If in the sub-district, use this device, must need to set up Fare Collection System, bring a lot of troubles to Property Management of residence, influence solar energy optical-thermal The Application of Technology, popularization.
And present heat collector is directly the circulation of the water in attemperater heating back to be used for the user, running water directly is heated in solar thermal collector, because of containing certain calcium, magnesium ion in the running water, and the heat collector water temperature inside can be than higher, even can surpass 80 ℃, and this just causes the solar thermal collector inwall to be easy to fouling, and pyroconductivity descends, thereby collecting efficiency is descended, influence the result of use of whole solar energy equipment.
Summary of the invention
The purpose of this utility model is that design is a kind of freely provides heating and domestic hot-water for the user, need not household metering, safeguard, operating cost is low, can combine closely with the building roof, be easy to the each door type central solar heating device of solar energy and architecture-integral design, and the solution solar thermal collector encrustation problem of employing new technology.
The utility model each door type central solar heating device comprises: solar thermal collector 1 and normal pressure heat collection water tank 2 one tunnel link to each other with thermal-arrest circulating line 8, and another set of routes thermal cycle water pump 3 links to each other with the pipeline that check valve 14, pipeline are connected to form; Supply water of pipeline that horizontal main 10 and heating agent water supply standpipe 11 be connected to form of normal pressure heat collection water tank 2 one road and heat exchange water circulating pump 4, heating agent links to each other, and another road links to each other with heating agent return riser 12, the horizontal main 9 of heating agent backwater and one of the pipeline that gate valve 13 is connected to form; Each family is led in the supply water other end of the pipeline that horizontal main 10 and heating agent water supply standpipe 11 be connected to form and the other end of the pipeline that heating agent return riser 12, the horizontal main 9 of heating agent backwater and gate valve 13 are connected to form of described heat exchange water circulating pump 4, heating agent, and the other end of the heat exchange loop at each family, heating equipment 6 and above-mentioned two-way pipeline is in parallel.
Be marked with heating agent in solar thermal collector 1, normal pressure heat collection water tank 2 and thermal-arrest circulation line 8, heating agent is demineralized water or other less scaling working medium.
Heat exchange loop comprises: running water pipe 18 is connected with the cold side water inlet of the plate type heat exchanger 5 at each family, and one of heat supply water pipe 17 and assisted heating device 7 links to each other, and the other end of assisted heating device 7 is connected with the cold side delivery port of the plate type heat exchanger at each family 5.
All pumps, electromagnetic valve are all controlled automatically by control system 15.
In this device, solar energy heat collector is just as thermal source, heating equipment 6 and plate type heat exchanger 5 heat exchange by each indoor setting provide heating and domestic hot-water for the user, and the water, electricity, gas that device is consumed all insert by oneself water meter of user, ammeter, gas meter.Its operation principle is: when weather was fine, solar thermal collector 1 was with the heating of the heating agent in the roof normal pressure heat collection water tank 2.When the user opened heating equipment 6, the heat medium circulation pump forced circulation started, and heating agent raises indoor temperature, for the user provides indoor heating by heating equipment 6 heat exchange; When the user used the domestic hot-water, heating agent was heated to be the user with running water the domestic hot-water is provided by plate type heat exchanger 5 heat exchange.Relatively poor in weather condition, sunshine, water temperature in the normal pressure heat collection water tank 2 was lower, then starts assisted heating device 7, for the user provides indoor heating and domestic hot-water when not enough.
The advantage of the utility model each door type central solar heating device is: under the situation of the centralized arrangement of solar thermal collector, can provide free heating and domestic hot-water for resident family, Fare Collection System need be set, be easy to the maintenance management of property, also be easy to the design of solar energy and architecture-integral simultaneously; Can effectively solar energy heat collector be separated with hot-water supply,, guarantee that solar thermal collector remains higher collecting efficiency increasing the problem that can solve the solar thermal collector internal incrustation under the condition of cost seldom.
