Description

Fie. 1

The invention relates to the field of solar engineering, in particular, to devices for producing dried fruits and growing vegetables using solar energy and is intended for round-the-clock use: from January to May, it works as a nursery. In summer it is used as a solar dryer for agricultural products, and in the autumn and winter periods as a greenhouse.

The closest is a continuous combined solar system comprising a drying chamber with an exhaust duct communicated with an external solid heat accumulator and a two-layer translucent topcoat 1.

The disadvantage of this combined solar installation is the short duration of the period of operation during the year, low efficiency.

The aim of the invention is to increase the efficiency of solar systems by providing year-round operation.

This goal is achieved by the fact that the dryer is additionally equipped with a water heating system with semi-cylindrical water heaters installed on the roof of the drying chamber and three accumulator tanks located inside the chamber in the upper part of its northern wall and placed along the length of the middle at equal distances and communicated between themselves .

In FIG. 1 is a general diagram of a drying plant; in FIG. 2 - section of the installation; in FIG. 3 is a section through a semicylindrical water heater in a hot box.

The combined solar installation contains an air heater-accumulator 1, a drying chamber 2, a brick fence 3. The north and side walls are made of bricks, the installation is oriented south and glazed 4. The air heater-accumulator is a double-glazed chamber 5 and has an angle of inclination to horizon 25 °. To reduce the heat flux, this part of the battery is thermally insulated 6 and 7. A coarse gravel 8 is used as the storage material; a pressure duct 9 is installed along the chamber wall. Round openings 10 are provided along the length of the wall that the heater / heater separates from the working chamber 10. On the upper part both lateral outer sides of the solar installation have hot plugs 1 with semi-cylindrical consecutively connected

water heaters 12. To heat the working chamber with water heaters, pipelines 13 are located at the bottom of the north wall along the bottom wall, and an exhaust duct 14 and water storage tanks 15 are installed in the upper part, which are simultaneously used to irrigate seedlings through pipeline 16. In the northern half Three cameras are mounted in the working chamber, and in

in the southern half, there are two shelves 17 and 18; on the shelves there are 19 wooden boxes with an area of 2 m each. Total useful area combined

fifteen

solar installation is 250 m.

In order to maintain the required temperature and humidity regime, as well as to create a microclimate for growing seedlings and drying agricultural products, a 20.21 ventilation system was installed in the solar installation.

1. The operation of the combined solar installation when using it as a nursery is carried out as follows.

In the afternoon, the sun's rays, passing through the transparent enclosure of the installation;

a) the storage material is heated and accumulated therein;

0 b) heat the air and the materials inside the working chamber;

c) they heat the water in the water heaters and ensure its natural circulation through the heating system of the working chamber.

5 At night, the opening between the batteries and the cooking chamber opens and the accumulated heat is gradually transferred to the cooking chamber. Our experiments show that the normal temperature regime for growing tomatoes, eggplant and pepper in any weather is ensured by the accumulated heat of the heating and irrigation systems. Experiments also

5 show that with multi-day blue temperatures, the temperature of the working chamber increased above normal, in such cases we connected a suction fan. To increase the brightness of

0 lower Rus (southern half), in the middle of the camera reflectors of 22 sun rays (polished sheets) are installed.

2. Combined solar works as follows.

5 The shelves contain the material to be dried (agricultural products). In the afternoon, the sun's rays passing through the installation's transparent enclosures:

a) heat the air and the storage material;

b) heat air, dried materials and building structures inside the working chamber;

c) they heat water in water heaters and ensure its circulation through the heating system.

At night, drying continues due to accumulated heat and heat from heating systems. We will also use a ventilation system to maintain the temperature and humidity conditions of the installation.
