The air outlet holes 43 are uniformly formed around the wall of the air duct 42.
The working principle of the invention is as follows: air in the upper space 61 of the airing room body 6 enters the lower space 62 of the airing room body 6 through the porous net 5, then enters the heat and humidity treatment equipment 2 through the air return box 1, and part of the air entering the heat and humidity treatment equipment 2 is mixed with the other part of air passing through the side ventilation valve 25 through the cold coil 23 and the hot coil 24, and the rest is discharged outdoors through the air outlet 27. The mixed air is pressurized by the blower 26 and then sent out of the heat and humidity treatment equipment 2 after being mixed with the outdoor air entering through the fresh air valve 28, and is conveyed to the air distribution pipe 4 through the air supply pipeline 3, and finally is emitted to the upper space 61 of the airing room body 6 through the air outlet small holes 43 of the air distribution pipe 4. And so on.
Wherein the porous net 5 in the airing house body 6 has the effect of making the air of the upper space 61 uniformly enter the lower space 62. The symmetrical trapezoid-shaped air inlets 12 of the air return box 1 have a uniform air return effect. The opening degree of the valve of the side ventilation valve 25 in the heat and humidity treatment equipment 2 can be adjusted to adjust the air quantity passing through the cold coil 23 and the hot coil 24, and the heat and humidity treatment equipment has the functions of adjusting the dehumidification quantity and the heating quantity. The opening degree of the fresh air valve 28 can be adjusted to adjust the amount of outdoor air entering the heat and humidity treatment equipment 2, and the air temperature and humidity entering the upper space 61 of the airing room body 6 can be adjusted.
