A kind of air collector heating systemTechnical field
The present invention relates to a kind of air collector heating system, belong to technical field of solar.
Background technology
At present, indoor heating mainly adopts conventional energy resource as air or heating installation, and its main drawback is not environmental protection.Air collector is arranged on roof, office space can solve indoor heating on daytime because adopt air collector directly absorb sunshine change into heat energy then replace indoor, itself as long as power consumption components and parts be blower fan, energy consuming ratio is lower, and environmental protection.But utilizing air collector to carry out heating system uses not extensive at present.At present in the rural area in some provinces of northern China, adopted passive solar house, not only improved grange indoor thermal environment in winter situation, and a large amount of heating coal consumptions have been saved, obtained applying to a certain degree, but owing to mostly adopting Te Longbu thermal-arrest body of wall, be subject to the not impact of the factor such as easy-maintaining and construction quality, many its heating functions of having lost gradually.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing for prior art, and a kind of solar energy air heat collector heating system of being convenient to installation and maintenance is provided.
For solving this technical problem, the invention provides a kind of air collector heating system, comprise cold air duct, air collector array, hot-flow flue, blower fan, Electric air valve, hot-blast outlet, cold wind import and control system, air collector array is arranged on outdoor top by collector bracket, air collector array is UNICOM's cold air duct and hot-flow flue respectively, cold air duct is provided with cold wind import, hot-flow flue is provided with hot-blast outlet, blower fan is arranged in cold air duct, Electric air valve is arranged in hot-flow flue, and control system control blower fan start and stop and Electric air valve open and close; Cold wind flows in air collector array and absorbs heat after cold wind import is driven by blower fan, and then hot blast is entered indoor by hot-flow flue by hot-blast outlet.
Described air collector array is formed through connection in series-parallel by multiple air collectors.
Described air collector is dull and stereotyped air collector, or vacuum tube air collector.
System realizes constant temperature circulating by control system, and indoor temperature is during higher than design temperature, and control system is closed blower fan, and opens Electric air valve, and hot blast flows to outdoor through exhaust outlet; Indoor temperature is during lower than design temperature, and control system is opened blower fan, and closes Electric air valve, and hot air flow is to indoor.
Beneficial effect: the present invention adopts independent air collector as heat collecting element, be convenient to installation and maintenance, its stable performance, safe, can move for a long time, can not produce problems of excessive heat, can not produce the problem of preventing freeze in winter yet, safeguard easy for installation and can meet the office space heating problem on daytime.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 cold air duct, 2 air collector arrays, 3 hot-flow flues, 4 blower fans, 5 Electric air valves, 6 hot-blast outlets, 7 cold wind imports, 8 collector brackets.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The present invention includescold air duct 1, air collector array 2, hot-flow flue 3, blower fan 4,Electric air valve 5, hot-blast outlet 6,cold wind import 7 and control system.
Described air collector array 2 is arranged on outdoor top bycollector bracket 8, air collector array 2 UNICOM'scold air duct 1 and hot-flow flue 3 respectively.
Describedcold air duct 1 is provided withcold wind import 7, and hot-flow flue 3 is provided with hot-blast outlet 6, and blower fan 4 is arranged incold air duct 1, andElectric air valve 5 is arranged in hot-flow flue 3, and 4 start and stop of control system control blower fan andElectric air valve 5 open and close.
Cold wind flows to the interior heat absorption of air collector array 2 aftercold wind import 7 is driven by blower fan 4, then hot blast enters indoor by hot-flow flue 3 by hot-blast outlet 6, indoor cold wind enterscold air duct 1 bycold wind import 7 simultaneously, forms next circulation, continuous heating room air.
Described air collector array 2 is formed through connection in series-parallel by multiple air collectors, is the components and parts that absorb solar energy and sunshine is changed into heat energy.
Described air collector is dull and stereotyped air collector, or vacuum tube air collector.
System realizes constant temperature circulating by control system.
When heat supply heating state, when indoor temperature is during lower than design temperature, control system is opened blower fan 4, and closesElectric air valve 5, after air collector heating hot air flow to indoor for room heating; When indoor temperature is during higher than design temperature, control system is closed blower fan 4, and opensElectric air valve 5, and hot blast flows to outdoor through exhaust outlet, to guarantee that room temperature maintains in comfort standard.
At non-heating season, as long as assurance room temperature is higher than setting value, just can closes blower fan 4, and openElectric air valve 5, hot blast flows to outdoor through exhaust outlet, utilize the hot stack effect of air collector, realizes intensified ventilation, and meets the requirement of room dehumidifying.
The present invention adopts independent air collector as heat collecting element, is convenient to installation and maintenance, its stable performance, safe, can move for a long time, can not produce problems of excessive heat, also can not produce the problem of preventing freeze in winter, safeguard easy for installation and can meet the office space heating problem on daytime.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
