How to make window solar collector with their hands

Saving energy and the use of free energy nature, such as solar radiation – is important and useful. In the last time there was a lot of work in this area, especially closer to finding craftsmen. But an important disadvantage of solar collectors, the air is distilled, it is necessary to admit that to pass from the sun-heated manifold hot air into the room, you need to prepare the walls, namely to make a hole. In connection with such an obstacle to supply your home solar collector, transferring energy through the air flow, not all enthusiasts are solved. Such luxury can afford predominantly the owners of rural and other private houses, but even for them, the hole in the wall of the house is not cause for rejoicing. It is therefore proposed to make a window device, which bypasses the problem.

To bypass this problem one of the inventors proposed to put a solar collector directly into the window opening.

Parts and tools for the production of the useful model:

1) a piece of plywood large thickness;

2) jigsaws;

3) fan, powered by 12 Volts;

4) foil;

5) black heat resistant paint

6) pieces of aluminum

7) blind or other material for beauty;

8) thermostat, used for incubators.

Now all details of the work to manufacture the solar air collector. Show also the advantages and disadvantages of this device.

As application areas for such devices is quite wide, the master decided to make a solar heat accumulator for heating their homes. So the manifold had to be set in the window of one of the rooms.

You need to try to choose a window which overlooks the most exposed to the sun direction – South to our latitude. As the inventor of the room, where there will be a solar collector not a single window, it was decided one of them to take under the manifold, and the light loss was avoided due to the fact that other Windows remained covered. For option, when the window is only one, he advises to put a header on the half of it, to not have to turn on the electric light to lighting the room

To get the maximum efficiency from the solar collector, it is important to install the device at a right angle to sunlight. In summer it can be almost horizontal position of the light receiver. But in winter, the position of the Sun relative to the horizon allows you to set it upright. Heat is most needed, just at this time of year.

A further scheme of functioning of the solar air collector:

 




The device of thick plywood. Inside covered with foil for heat retention and even raise the temperature of the media.





 

after you have completed the preparation works in the solar collector you need to put a plate of aluminum. the author of working the plate at a certain angle in order to capture and maximize the Sun's rays at a right angle to this plate had a little bend.

Then you need to make holes in both parts of the device. Since hot air moves upward, the hole at the bottom need not warmed air into the housing through the top of the hot air will go into the room.



To enhance the effect of the warming of the solar collector, you need to paint it inside black heat resistant paint.

For best circulation of warm air in the top hole put the fan from the PSU of the PC for 12 volts. To automatically control its operation, set the thermostat for incubators. Adjustment configured to supply air into the room while heating it to 30 degrees.





Now you can give the device a presentable appearance. Not bad cope with this task a fabric of suitable size, which is attached to the manifold, having slots.





You are now ready to install in the opening window and operating a collector that will absorb energy and warm the house in Sunny weather. You can add the solar panel and the energy from it to power the fan.





Advantages of window solar collector:
1) Saving on heating apartments in the winter. Heated in spring and autumn when the Central heating is turned off. Heated country house in cool weather, when the sun is shining, but the temperature outside is low.

2) Easy mounting on the window opening.

3) low cost compared to other air collectors.
4) Easy dismantling for the summer period.

Disadvantages:
1) the Darkening of the room enclosure.
2) Low power due to the small usable area of the collector.
