AUTONOMOUS GREENHOUSE WITH NIGHT HEATING AND DAYTIME VENTILATION USING SOLAR ENERGY Russian patent published in 2021 - IPC A01G9/14 

FIELD: agriculture.

SUBSTANCE: invention relates to greenhouses with night heating and daytime ventilation with solar energy and can be used in agriculture. The greenhouse contains a support structure on which solar collectors 1 are placed, connected by inlet 2 and outlet 3 pipes with a heat accumulator 4. The support structure is made of several arc-shaped pipes 5, on each of which an arc-shaped pipe 6 of larger diameter and shorter length is installed coaxially with a small gap with the possibility of moving and fixing its position by rigid connection. At the same time, the upper and lower ends of these pipes 6 are connected horizontally to each other, forming a frame 7 for fixing each solar collector 1. Solar collectors 1 are located from the centers of arc-shaped pipes of larger diameter perpendicular to their chord 8, drawn from the ends of the pipes 6, and fixed with mounting supports 9 and 10 from the ends of the pipes 6 to the upper and lower parts of the collectors 1, respectively. The heat accumulator 4 is made in the form of side pipes connected in series by pipes 11, held by mounting brackets 12 on the longitudinal bases 13 of the greenhouse with a small gap to the light-permeable coating. Check valves 14 are mounted in the inlet and outlet pipes, and a circulation pump 15 is built into the inlet pipe, connected to solar panels 16 fixed on mounting supports 9 and 10. In the greenhouse, an increase in heating efficiency is provided.

EFFECT: extension of the range of greenhouse solutions.
