A kind of solar energy hot blast circulation water heating system
Technical field
The utility model relates to solar energy resources and utilizes field, relates in particular to a kind of air type solar energy hot water supply system.
Background technology
At present, countries in the world all, advocating energy-saving and emission-reduction, make full use of regenerative resource.Under the ordering about of this guiding, be accompanied by solar energy industry and move to maturity just steadily, solar water heating system has obtained large-scale application.
The photo-thermal industry of China has been passed through the development of two more than ten years.Solar heating engineering market has also experienced from rural area to city to concentrated process, solar energy industry is in the critical period of upgrading transition, urbanization process has highlighted the importance of solar heating engineering architecture-integral more, and hot water engineeringization is leading industrial market fast development.
Conventional solar hot water all using liquid especially water as conducting heat, thermal storage medium, there is defect and drawbacks such as " easily freeze winter, over-heating in summer, leakiness, perishable, the life-span is short ", particularly outstanding in the area of cold, lack of water, supply of electric power deficiency.And the area that these economic developments relatively lag behind exactly, natural environment is relatively severe is that solar energy resources is abundant, the area that heating and hot water supply requirement are large.
Solar heating engineering system is in the urgent need to thoroughly solving technically " safety " and " life-span " two hang-ups of engineering, if " safety " was broken through with " life-span ", solar heating engineering system will be as the develop rapidly of emerging rapidly in large numbersBamboo shoots after a spring rain.
Utility model content
The utility model, for the existing shortcoming of above-mentioned prior art, provides a kind of solar energy hot blast circulation water heating system.
The utility model solves the technical scheme that its technical problem adopts:
A kind of solar energy hot blast circulation water heating system, mainly comprises:
One group of air collector, it is by helical vacuum pipe, header and be configured to, and this stent support vacuum tube, header, make heat collector and Integration of building;
Air water heat-exchanging water tank; On the inner bag of this domestic water water tank, there is individual interlayer, be used as the passage of hot blast, complete the heat exchange of wind and water;
A circulating fan;
A hot-air system high-temperature safety valve;
The utility model priority scheme is as follows:
Above-mentioned air collector, air water heat-exchanging water tank, circulating fan, hot-air system high-temperature safety valve are each other for air channel connects.
Above-mentioned solar heat wind system, in order to meet the heat demand of domestic water water tank, adopts the exchange heat of water tank inner air and water, and heat exchange area is large, and thermal loss is few.
The utility model compared with prior art has the following advantages:
1, a kind of solar energy hot blast circulation water heating system selects air collector, air water heat-exchanging water tank, circulating fan, hot-air system high-temperature safety valve each other for air channel connects.Wherein hot-air system is installed on outdoor (as the balcony) of building, by pipeline, the hot water in water tank is guided to the water spot such as kitchen, toilet.Native system is owing to having adopted wind as circulatory mediator, can effectively prevent pipeline frozen block, leaks, the phenomenon such as corrosion occurs.
2, the heat-exchanger rig of system adopts in water supply tank inner bag outside and makes air channel interlayer, the definite stainless steel tube that says employing diameter 10mm, make the helical form of coarse pitch, be attached to the outside (being generally bull) of inner water tank, then make the cylindric outside that is enclosed within helix tube with galvanized sheet, form air channel interlayer, the heat transfer process of system is completed in water tank inside, can effectively prevent heat loss, reduce system equipment quantity, occupy little space, system is installed the advantages such as simple.
3, system is furnished with air system high-temperature safety valve, can in the time that high temperature appears in solar heat wind system, can automatically open, and discharges high temperature, the infringement that control high temperature causes system.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model hot-water heating system.
Reference numeral:
1. air collector; 2. hot-air system high-temperature safety valve; 3. circulating fan; 4. air water heat-exchanging water tank.
Detailed description of the invention
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, for a kind of structural representation of solar energy hot blast circulation water heating system, comprise air collector 1, hot-air system high-temperature safety valve 2, circulating fan 3, air water heat-exchanging water tank 4.
Particularly, above-mentioned some air collectors 1 couple together becomes one group of air collector, one end at this group air collector connects a hot-air system high-temperature safety valve 2, be connected with the inlet and outlet of air water heat-exchanging water tank 4 by air channel, blower fan 3 is connected in air channel, the circulatory system is by temperature difference control, after temperature in system raises in heat collector air channel with water tank in temperature formation temperature poor, when temperature difference reaches setting value (as 10 DEG C, adjustable) time, circulating fan 3 starts to start, wind system is circulated, heat in heat collector is brought in water tank, in heat collector, temperature declines, when the temperature difference of temperature in heat collector and water tank drops to when setting value (as 3 DEG C, adjustable) time, circulating fan stops operating, the air water heat-exchanging water tank that solar energy wind system is carried heat energy by this temperature difference control stores.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
