FIELD: heating.
SUBSTANCE: invention relates to ventilation and air conditioning engineering and can be used for the distribution of plenum air into various premises. The task to be solved by the invention consists in the creation of an air outlet device, with the simple design, the use of which should provide such technical result as the decrease of the coefficient of attenuation of the flow rate of plenum air and increase of comfort of stay in the ventilated room due to the high intensity of dampening of the flow rate of the supply air jet. The essence of the invention is that the ventilating air outlet device contains an assembly frame around the hole for air outlet of a square or rectangular shape on which from the ventilating flow the arch is installed in the form of a semi-cylinder curved plate.
EFFECT: device allows using the air outlet device in premises with small volumes, and also in premises with high hygienic requirements to air mobility and temperature.
