GREENHOUSE FOR GROWING VEGETABLES Russian patent published in 2020 - IPC A01G9/24 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural structures. Greenhouse for growing vegetables is arranged in the form of an air closed chamber located on the ground surface. From above it is limited by a convex transparent cover. Greenhouse can be single-section and multi-section. Outer walls are continuous. Internal walls at multisection structure are not solid and are made of separate posts embedded in soil and combined in transverse tightening, and in longitudinal - by crossbars. Device for reducing air temperature in air closed chamber of greenhouse is combined with roof and is made in the form of double-glazed window from two parallel glass with cavity between them, filled with water, if necessary flowing. In the daytime the cavity of the air chamber of the greenhouse is heated by solar radiation. At the same time part of solar radiation is absorbed by double-glazed window water, and part is reflected. From the chamber, excess heat is diverted into the water from the double-glazed window. Air temperature inside greenhouse cavity is set proceeding from rational temperature mode for vegetables growing. Water temperature in the double-glazed window cavity is calculated proceeding from the heat balance estimation. Glazing unit can be quite powerful. Then water is cooled at night due to heat exchange with external air. But it is more effective and reliable to equip the water cooling system, which is connected to the double-glazed window cavity by means of pipes. Efficiency of the proposed technical solution consists in the fact that in conditions of a hot climate it is possible to provide a normal temperature mode of an air chamber, using the whole light day without artificial obscurity.

EFFECT: proposed design can be widely used for other premises in hot climate, for example, various public buildings, cafes, etc.
