<p>When drying, heated drying air is blasted onto flat textile passing between a pair of jet chambers (5, 6) with outlet air nozzles (70). During blasting the heated drying air onto the flat textile, the direction and size of velocity vector of the heated drying air leaving the outlet air nozzles (70) are changed, whereby the magnitude and time characteristic of this change takes place in individual portions of the jet chamber (5, 6) surface so that increase in intensity of the heated drying air movement along the surface of the dried flat textile as well as increase in intensity of withdrawal of the heated drying air reflected from the flat textile surface and saturated with steam are achieved, which results in a higher drying effect to the flat textile. The proposed air-conditioning circulation circuit comprises air heating unit (1) to the outlet of which a fan unit (2) is assigned by its inlet. Said fan unit (2) outlet is connected with both an upper and a lower jet chambers (5, 6), whereby both the jet chambers (5, 6) have variable cross section and are provided with air outlet nozzles (70). The fan unit (2) contains a pair of independent pipelines (20) situated side-by-side, where to the inlet of each of them there is assigned one axial-flow fan (21) that is drivingly coupled with a frequency-controlled motor (210), whereby outlet hole of each piping (20) is connected with a portion of an inlet hole (30) of a mixing chamber (3), whose outlet hole (31) is coupled with both the upper and the lower jet chambers (5, 6).</p> |
