Embodiment 1
[0035] Compared with the velocity distribution of deflectors with different radians, such as figure 2 As shown, the traditional deflector is a straight baffle without curvature. When the deflector produces different radians of upward protrusion and downward depression, the resulting diversion effect will change and affect the airflow organization form. Such as figure 2 (b) is the velocity distribution nephogram in the ward formed by the curved deflector 5 . The arc deflector 5 of the present invention is concave downwards, and the curved radian is Compared with other curved radians, it can be found that under this downward concave radian, the air outlet speed can meet the wind speed requirements inside the ward, and the jet flow area can reach the patient's breathing area, which shows that the air directional transmission technology in the pathogenic microorganism prevention and control ward of the present invention The curved deflector has a good improvement effect.
Embodiment 2
[0037] The present invention is compared with the airflow organization of traditional ward interior ventilation, as image 3 As shown, it is found that the wind coverage of the traditional ward ventilation system is poor, the wind speed does not meet the requirements, etc., and the fresh air is mixed with the polluted air in the room. After the vertical wall-attached jet is added to the traditional ward, it is drained through the arc-shaped deflector, and at the same time merged with the air flow of the air purification device. The air directional transmission technology in the pathogenic microorganism prevention and control ward of the present invention sends the air flow to the designated area in an organized manner, that is, It shows that the air directional transmission technology in the pathogenic microorganism disease area has a good air supply effect.
Embodiment 3
[0039] Such as Figure 5 As shown, for the purification coating smearing wall 13 wind speed area distribution streamline diagram, 6 typical curves will clean the coating coating wall 13 is divided into different 4 areas; Wherein area one is by typical curve 1, typical curve 2, typical curve 3 and Typical curve 4 is surrounded, area 2 is surrounded by typical curve 1, typical curve 2, typical curve 3, typical curve 4 and typical curve 5, area 3 is surrounded by typical curve 5 and typical curve 6, and area 4 is surrounded by typical curve 6 surrounded.
[0040] The regional distribution of wind speed is determined by the wind speed proportional coefficient of each region, and the wind speed proportional coefficient is the ratio of the regional wind speed to the wind speed of the air supply outlet of the slit Among them, V x Be the regional wind speed, and the regional wind speed is the wind speed within 10 centimeters of the wall 13 surface where the purification coating is ...
