GREENHOUSE AND METHOD OF ITS MICROCLIMATE KEEPING AND ADJUSTMENT Russian patent published in 2015 - IPC A01G9/14 A01G9/24 

FIELD: agriculture.

SUBSTANCE: greenhouse includes framework, light transparent enclosure, chambers for air mixing with turbochargers installed at the greenhouse ends at diagonal to each other, system of air heating and temperature, humidity, carbon dioxide concentration regulation in supplied air, and regulated ventilation holes with exhaust fans in the greenhouse roof. Inside space of the greenhouse is provided with the longitudinal curtains out of light transparent material separating it to at least four rows of air corridors, at that one curtain is located at center of the greenhouse, and other along side walls. Mixing chambers are provided with air valves connecting them with internal space of the greenhouse and environment with possibility to regulate air flowrate, and with at least one gas burner, heater, temperature and humidity transmitters installed inside and at output of the chambers. The method includes air supply with specified parameters from the mixing chambers to bottom part of the greenhouse along internal air corridors, creating opposite convection flows separated to two parts, one is directed to the opposite mixing chamber, and another is directed to the air corridor along the side walls of the enclosure with further return to the mixing chamber. In the mixing chamber the air flow is saturated by carbon dioxide being combustion product of natural gas, is heated or cooled, if necessary. Temperature and humidity are adjusted by replacement of the overheated and waterlogged air removed via the ventilation holes by dry external air supplied to the mixing chamber, and by flows recirculation from internal and external air corridors by regulation of their flowrates ratio using the air valves.

EFFECT: reduced materials and power consumption, improved conditions of plants life activity.
