FIELD: heating.SUBSTANCE: present invention relates to a cooling unit with VAV-function, which is designed to feed into the premises of the cooled or heated inlet air. The device for air treatment, in which the cooling unit is equipped with a pressure chamber for the inlet air with openings for supplying inlet air flow into the mixing chamber, which also receives recirculating air from the premises through the coil, and the amount of inlet air is regulated by displaceable adjusting panel having a number of openings where the openings in each group have different sizes, and where on the surface of the pressure chamber under the adjusting panel there is an opening for each group of the adjusting panel and then when the displaceable adjustment panel is moved to a position where the selected opening is aligned with the opening on the surface, the same number of openings always opens from the pressure chamber to the mixing chamber, and the openings are always at the same position, and the openings on the adjusting panel and the openings on the surface are located along the entire length of the mixing chamber, at that the surface and, correspondingly, the adjusting panel is located with the inclination with respect to the coil, thereby the inlet air flow rate is provided, and the recirculating air flow is formed.EFFECT: device is characterised with low power consumption and meets the specific functional requirements of a particular unit.7 cl, 4 dwg |
