Abstract

The invention relates to air conditioning technology. The purpose of the invention is to intensify the heat and moisture treatment of air and reduce the size of the device.

Turbulizadi flow in the confuser of the first P 9 flag splitters 4 leads to a continuous flow around the diffuser P 9 even at considerable opening angles (up to 40), which reduces the pressure loss and reduces the size. P 9 is made of a two-layer elastic material with an internal hygroscopic and external non-hygroscopic layers, which leads to additional flow turbulization due to vibrations of the polymer film under the action of the gas flow. 1 3.P. f-ly, 3 ill. c & (L figure 1 co j co co / / / J2 / J / 7 1B 15 77

Description

The invention relates to air conditioning technology.

The aim of the invention is to intensify the heat and humidity treatment of air and reduce the size.

Fig, 1 schematically shows the proposed device, the section; in fig. 2 shows section A-A in FIG. one; Fig. 3 shows a variable cross-section sprinkler.

The device for heat and humidity air treatment contains a fan 1 and an irrigation chamber 2 behind it along the air course with nozzles 3 placed in it, times fO

the input speed, and falls on the walls of the confuser of the second pipe 9, of the stack through pipe 12 into the tray 6, from where the pump 11 sends the liquid back to the nozzle 3.

Turbulization of the flow in the confuser of the first pipe 9 is a flag: with new crushers 4, the diffuser of the first pipe 9 is continuously separated even at considerable opening angles (up to 40), which reduces the pressure loss and reduces the size.

The gas flow rate in the confuser of the second pipe 9 again by snubber 4 and the separators 5 of the flag 15 will melt, increasing of the razor type and the pallet 6, the connectedness of the velocities that have not leaked out to the nozzles 3 of the liquid circulation circuit 7. The irrigation chamber 2 is made in the form of a frame 8 and a sequence

two confused-diffuser nozzles 9 made of a two-layer elastic material with an internal hygroscopic and non-hygroscopic external layers, and the grinders 4 and separators 5 are installed in the minimum sections of the nozzles 9. The nozzles 3 are made in the form of tubular sprinklers 10 section. Circulation of the liquid of the liquid with respect to the gas flow rate, which also intensifies the evaporation of these droplets. Then the gas with non-dropping liquid droplets passes the flag-shaped separators 5, in which droplet moisture is effectively separated from the gas stream, which passes Next to the diffuser of the second 25 nozzle 9 and supplied to the conditioned room. The turbulization of the gas flow in the diffuser of the second nozzle 9 also leads, as in the diffuser of the first nozzle 9, to an increase in

into the gas stream of liquid and gas droplets, these drops deviate from the gas flow lines, the drops fall on the walls of the diffuser of the second pipe 9 and through

The device works as follows.

The gas (air) supplied by the fan 1 passes the confuser of the first pipe 9, increasing its speed at a constant drive power of the fan 1, reaching the maximum value at the narrowest point of the confuser. Installed in this part of the confusion of the liquid level in the pallet 6 there are a valve 14 to feed the liquid and the overflow tube 13. In cases where evaporative cooling is not enough, the system can be fed

Bore-down flag crushers 4 are intensively carried out using heat-exchanging oscillations, effectively dispersing the liquid (coolant) coming from the nozzles 3, cooling and moistening the passing gas. Boost

The turbulence of the gas flow due to the film, the latter oscillates under the influence of a more intense oscillation by the action of the gas flow, and the additional flag elements contribute to the improvement of mass transfer. The presence of diff. fusor of the first pipe 9 along the ganic 17, in which the supplied liquid is cooled.

When performing the walls of the diffusers and confusion of the pipes 9 from polimetalno turbuliziruet it and thereby contributing to the intensification of mass transfer.

The basal flow leads to additional turbulence. A part of the droplets of the fluid carried by the air flow moves along the lines of its movement, deviating from the direction of the vector

the input speed, and falls on the walls of the confuser of the second pipe 9, of the stack through pipe 12 into the tray 6, from where the pump 11 sends the liquid back to the nozzle 3.

Turbulization of the flow in the confuser of the first pipe 9 is a flag: with new crushers 4, the diffuser of the first pipe 9 is continuously separated even at considerable opening angles (up to 40), which reduces the pressure loss and reduces the size.

The velocity of the gas flow in the confuser of the second nozzle 9 increases again, and the difference in the velocities of non-dropping drops increases.

fluid relative to the flow rate of gas, which also intensifies the evaporation of these droplets. Then the gas with non-dropping liquid droplets passes the flag-shaped separators 5, in which droplet moisture is effectively separated from the gas stream, which then passes the diffuser of the second pipe 9 and is supplied to the conditioned room. The turbulization of the gas flow in the diffuser of the second nozzle 9 also leads, as in the diffuser of the first nozzle 9, to an increase in

velocity differences not evaporated

into the gas stream of liquid and gas droplets, these drops deviate from the gas flow lines, the drops fall on the walls of the diffuser of the second pipe 9 and through

the drain pipe 12 flows into the sump 6. Without evaporating the fluid from the sump 6, passing the filter 15, the regulating valve 16, the pump 11 is again fed into the nozzles 3. To adjust the level of the fluid in the sump 6, there are a liquid feed valve 14 and an overflow tube 13. In In cases where evaporative cooling is not enough, the system can be fed

carried out using heat exchange

17, in which the feed fluid is cooled.

When the walls of diffusers and confuser pipes 9 are made of polymer film, the latter oscillates under the action of a gas stream, in addition

to turbulize it and thus facilitate the intensification of mass exchange.
