Abstract

Usage: in ventilation. SUMMARY OF THE INVENTION: supply air is supplied to the room in jets from top to bottom with the possibility of individually adjusting their parameters and then removing air from the lower part of the room. Air is removed by a laminar flow. The upper boundary of the laminar flow is maintained below the human respiratory organs. 1 ill.

Description

The invention relates to ventilation and can be used in industrial and public buildings.

The aim of the invention is to reduce energy consumption and improve working or resting conditions at fixed locations.

. The drawing shows a room ventilation system for implementing a method of ventilating a room with fixed locations for a person.

The ventilation system of the room includes room 1 with fixed places 2 and 3 for work or rest, supply air ducts 4 and 5, switchgears 6. Air duct 4 has valves 7, which are equipped with fixing devices (not shown in the drawing) and rods 8 and 9 The switchgears 6 at the points of the air outlet therefrom are provided with perforated panels 10 for forming diffuse jets. The fixed places 2 and 3 of a person's stay in the room have a lower 1 zone located below the human respiratory organs and an upper T2. In the lower part of room 1 and zones of places 2 and

3 there is an exhaust opening 13 for drawing air from a room.

The ventilation system of the room operates as follows.

The air is pre-treated (cooled, drained, heated, etc.) and fed into the duct 5, from which it enters the switchgear 6. From the switchgear 6, the air is distributed by jets covering fixed locations 2 and 3 of the person. In order to provide the required individual parameters of the air medium at each fixed place of a person's stay, duct 4 is supplied with air into the room 1 with parameters different from the parameters of the air supplied through duct 5. By means of tg 8, 9, the position of the valves 7 in the switchgear b and therefore, the amount of intake air from the duct 4 and mixed in the switchgear 6 with the air supplied through the duct 5 is changed. To provide the necessary odor and air jet to the switchgear

b air with pre-prepared odors, for example, forests, pestilence, etc., is supplied through separate channels of the duct 4. The supply jets after ventilation of fixed places of human residence by the flow of the CMM laminar rotor gave that from the lower zone of the room through opening 13 (gap along; walls).

the movement of air jets and a laminar flow stream with room air in areas of fixed human areas, which leads to an improvement in working and resting conditions.

The absence of the need to ventilate the entire area of the room according to this technical solution leads to a decrease in the metal consumption of the ventilation systems and their capacities, and therefore to a reduction in capital and operating costs.

SUMMARY OF THE INVENTION A method of ventilating a room with fixed places for a person to stay by supplying flowing air to the room with jets from top to bottom with the possibility of individually adjusting their parameters and then removing them air from the room in its lower part, characterized in that the air is removed from the room by a laminar flow from the lower zone of the room, while the upper boundary of the laminar flow is maintained below the human respiratory organs.
