Description

The invention relates to the technique of ventilation and air conditioning.

The aim of the invention is to expand the functionality and increase the efficiency of air treatment.

Fig. 1 is a schematic diagram of a room ventilation system; figure 2 - the processing unit Bos - spirit; FIG. 3 shows a schematic diagram of a ventilation system for a room with additional heat exchangers; Fig. 4 shows an air treatment unit with a shower device; FIG. 3 is a schematic diagram of a ventilating room ventilation system with a recirculation channel and air distributors.

The room ventilation system contains an air treatment unit 1 with inlet and outlet pipes 2, 3 and 4, 5 exhaust and outside air communicated respectively with room 6 and the atmosphere.

The air treatment unit 1 is made in the form of a multichannel membrane module 7, having a housing 8 and parallel partitions 9 of polymeric material with gas-tight gaskets 10, forming between them alternating ducts 11 and 12 of exhaust and outside air.

But at least part of the partitions 9 is made of polymeric nuclear membranes 13.

The exhaust air ducts 11 are located in the module 7 in a cross direction relative to the direction of the outside air ducts 12, and the exhaust air outlets 4 and 5 are connected to the room 6 and the atmosphere, respectively.

The inlet and outlet pipes 2 and 4 of the exhaust air and / or the inlet and outlet pipes 3 and 5 of the outside air can be equipped with heat exchangers 14 and 15 connected in parallel to them.

The system may contain a source of compressed gas or liquid (not shown) and a shower device 16 connected to the latter, located in the channels 11 and 12 of the exhaust and outside air.

The shower unit 16 may be located in the gaskets 10 of the membrane module 7.

In the exhaust air channel 11, an air pretreatment unit 17 and a preheater 18 can be installed.

The treated air is supplied to room 6 via distributors 19 and 20.

The air treatment unit 1 may have a recirculation duct 21 for exhaust air.

The room ventilation system operates as follows.

The exhaust air from the room 6 through the inlet pipe 2 enters the exhaust air ducts 11, where as a result of diffusion mass exchange with the outside air passing through the ducts 12, the exhaust air is enriched with oxygen while reducing the concentration of carbon dioxide.

The dust-free, heat-treated exhaust air in the unit 17 and the preheater 18, enriched with oxygen and freed from excess carbon dioxide in the air treatment unit 1, treated exhaust air through the outlet nozzle 4 is again supplied to the room 6.

The external air after its mass exchange with exhaust air in the air treatment unit 1 is vented to the atmosphere through the outlet nozzle 5.
