At this time X and X 1 Included angle < 40 DEG, resulting in a top fan air supply speed V that enables the air flow from the second purge space 111 to flow directionally to the raised floor 300 5 ＝0.45m/s；
S3 by measuring the vertical height distance h=3m between the top blower 220 and the raised floor 300 and at V 5 The ventilation times of the present library cleaning system, n=3600/(H/V), were calculated by combining 0.45m/s with a preset time of 3600 seconds 5 ) The number of times =540,
at this time, N is more than 200 times, and the actual working wind speed V of the top fan 220 is obtained 6 =0.45 m/s and the actual working speed V of the side blower 140 7 =0.3m/s, thus far the construction of the library cleaning system was completed. In the present embodiment, V 1 、V 3 、V 5 、V 6 Is the same as the value of V 2 、V 4 、V 7 In other embodiments, the values are the sameThe actual numerical value is calculated or measured according to the actual use condition change.
In summary, by the cleaning method of the vertical warehouse cleaning system in this embodiment, the actual purge wind speed of the top blower 220 and the actual purge wind speed of the side blower 140 with the best cleaning effect can be obtained, so that the high cleaning effect can be achieved, and meanwhile, it is ensured that the combined purge wind can flow from the raised floor 300 through the second purge space 111 from the first purge space 210 without generating vortex, and the whole purge process is efficient and stable.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present application will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present application.
