Description

The invention relates to ventilation and serves to ventilate livestock buildings as well as rooms with large amounts of heat and moisture.

The purpose of the invention is to expand the operational capabilities and intensify heat exchange,

The room ventilation system 1 contains a supply fan 2 and the AFTERDIYa i i, j connected to it: onG

connected main air duct 3 and distributing air duct 4 with air distribution gaps 5. In addition, the system contains a recirculation fan b for intake of indoor air, the inlet of which is connected to the pipes 7, 8 connected to the room and the additional pipe 9 associated with the atmosphere. The nozzles 7-9 are closed off by the flap valve 10. The outlet of the fan 6 is connected to the recirculation pipe 11 with an air-eelectric outlet, a slit 12 located in its lower part, and the pipe 11 is located above the main air duct 3. The system also contains air exhaust vents 13, mounted on the periphery of the room, the intake pipes 14 of which are located below the main duct, and the trays 15 for collecting the equipment located under ;.Hydrgl:; ь: Eccentric 3. 3.

The main air ducts 3 are located directly at the ceiling of the room (see Fig. A}, the recirculation pipe 11 forms two cavities located on both sides of the main duct 3 and contains additional air distributing slots 16 facing the main duct.

The system works as follows. In the cold period of the year, the check valve 10 closes the additional connection 9. At the same time, the fan. 2 supplies the cold outside air to the central air duct 3. At the same time, the fan 6 delivers warm humid air from the room through the air inlets 7.8 located in the most humid places of the room to the recirculation air duct 11 and through the air gap 12 to the ventilation duct 3. Around its surface, the internal air of the room gives off some of the heat to the cold supply air. KROP. Moreover, water vapor condenses on the outer surface of the main duct. As a result, latent evaporation heat is released, which also heats the intake air. The latter enters the dispensing hub 4, and then the B room is fed through the air-distributing gap 5. The condensate formed is blown off into the trays 15 and removed from the room, which increases the efficiency of heat exchange. As a result of heat exchange, the supply air is heated, as well as the cooling and dehumidification of the indoor air. Under the action of overpressure in the room, part of its air is removed through the air shafts 13gv atmosphere. The location of the open ends 14 of the shaft 13 below the supply air,

creates an air cushion in the upper zone of room 1, and also allows exhaust air to be removed directly from the working zone of room 1. In the transitional

and a warm period of the year, when the outdoor temperature rises and the need for heat exchange disappears, the check valve 1C closes the pipes 7 and 8 and opens the pipe 9 to supply the outside
