Embodiment 1

[0059] In this embodiment, a 2m * 2m * 2.4m (L * W * H) for the study of building space, the work window in the building space 5 disposed next to a staff, the staff has a wall in front of the distribution table, see FIG. 1. Set supply air temperature of 22 ℃, velocity of 0.9m / s. Personnel 34.5 ℃ constant wall temperature, the wall temperature was 28 ℃ six constant wall temperature, the remaining heat insulating wall is set to a boundary. Blower plenum air inlet is slit 1, the air blowing outlet is located on the same side, the right person. Operating window 5 closed state: in the absence of work requires windowing operating window 5 closed state, since the lower blowing port 4 does not receive "instruction" is normally closed, by blowing treated air into the plenum chamber 3 a pipe 14, the first current through the first baffle plate 9 and 11, a relatively uniform velocity air blower opening first cavity 2 by continuous feeding, such as Figure 7 , Since the effect of wall, attac...

Embodiment 2

[0061] Such as Figure 8 Shown, there are two air outlet, a person is in front of the window, with the second embodiment example 1, the same as in Example 1 remaining boundary conditions. Operating window 5 ON state: In windows that open by job status window opening 5, the treated air is fed through the blower duct 3 a first plenum chamber 14 1 through the first plate 9 are flow and a first flow guide plate 11 enters the second cavity 15, both through the second flow plate 16 enters the third chamber 10 and the second guide 12 after the deflector. The second inner cavity 15 of air sent out by the outlet 4, is attached to the wall surface is formed continuous stream conveyed forward, the momentum after striking attenuation, eventually creating a uniform velocity field and temperature field in the comfort booth working area. At the same time, open time windows, with an increase in the magnetic block and the distance of the wireless transmitter, when the distance therebetween is great...

Abstract

The invention belongs to the technical field of ventilation airflow organization, and relates to an air curtain air supply system linked with window opening, which comprises a static pressure box, a window magnetic switch, a signal receiver and a magnetic control switch, the static pressure box comprises a box body, one side of the box body is connected with an air supply pipe for supplying purified air, the lower side of the box body is provided with a lower air supply outlet, the upper side of the box body is provided with an upper air supply outlet, and the lower air supply outlet is a normally closed air outlet; an air baffle is arranged at the lower air supply outlet, the signal receiver and the magnetic control switch are arranged on the air baffle, and the signal receiver is connected with the magnetic control switch; the window magnetic switch is arranged on an openable working window and comprises a magnetic block and a wireless transmitter; when the working window is opened, the wireless transmitter is communicated with the signal receiver; and when the working window is closed, the wireless transmitter is disconnected from the signal receiver. In a non-working state, the working window is closed, the lower air supply opening is closed, and air supply is stopped. And compared with a normally open air curtain, the use amount of fresh air is reduced to a great extent, and the energy consumption is reduced.

Description

Technical field [0001] The present invention belongs to the field of ventilation and air flow tissue, involving a disconnective air supply system and its working method thereof. Background technique [0002] As the number of main auxiliary facilities on the road, the number of main auxiliary facilities is also sharply increased. The highway toll pavilion is located in the center of the traffic main road. It is in sensitive areas that pollute the environment along the road. The idle speed of motor vehicles is incompletely combustion when fuel is incompletely combustion. Nitrogen oxides and harmful materials such as nitrogen oxides, and the pavilion fees are often required to open due to work, and harmful pollutants are invaded indoors through the work window, which has a great threat to the health of staff. [0003] One of the pathways of viral communication is that aerosol propagation, breathing, cough, speech, and spitting, etc. may produce aerosols. According to relevant inform...
