The present invention relates to a device for modeling air draught for research purposes of animal thermoregulation. It consists of an enclosed air conditioned stable unit (16) with a solid internal partition (7), which creates in the enclosed air conditioned stable unit (16) an experimental section (1) and a cold section (2) of different internal temperature. Both the sections are interconnected in the bottom (14) by a pipe (6) through a sludge channel (8). Free end of the pipe (6) in the experimental section (1) is attached by a clamping clip (10) to a pipe holder (9) and the free end of the pipe (6) in the cold section (2) is attached by means of a clip (5) to an axial-flow fan (3), which is arranged in a fan holder (4). In the experimental section (1), there is arranged a thermographic camera (13). A fixing cage (11) for an animal (12) is fastened by a horizontal yoke (15).
