FIELD: agricultural engineering, in particular, design of agricultural cultivation constructions with protected ground, such as greenhouses.
SUBSTANCE: greenhouse has light transparent covering and above-ground heating system made in the form of closed underground zone communicated with atmosphere and space under light transparent covering. Greenhouse is equipped with exhaust shaft positioned in upper part of light transparent covering, at side of end opposite to end adjacent to which feeding branch pipe is disposed. Underground zone is made in the form of air duct-heat-exchanger formed as hollow rod having continuous wall, said hollow rod being buried into ground. Air intake device is positioned near one side of greenhouse and feeding branch pipe is located near opposite end of greenhouse.
EFFECT: improved parameters of microclimate within greenhouse, simplified construction and enhanced reliability in operation of greenhouse.
