FIELD: construction engineering. SUBSTANCE: this actually relates to construction of large-span spatial coverings. Structure is made up of two spatial coverings located one inside other. Their single-layer roofs are made of cheep and light-weight materials secured on single-screen formations which are woven from polymeric twisted ropes. Preset temperature and air humidity inside structures are maintained and controlled by layer of water constantly flowing down over external sides of internal covering and by streams of compressed air which draws drops of water from aforesaid layer of water and carries them into space between coverings where turbulent flows of humid air are created which are also restricted by internal walls of band made of water-repellent material in the form of truncated cone. This band due to possible adjustment of clearance between it and internal covering provides additional facility for air conditioning inside structure. EFFECT: high efficiency. 2 cl, 1 dwg
