Indicate that still (18 DEG C < temperature < 22 DEG C or 26 DEG C < temperature < 28 DEG C), ◎ indicates best (22 DEG C≤Wen Du≤26 DEG C)
Operating condition two:
Such as Fig. 3, face Hangzhou that the city Ping Yintai kindergarten building carries out 27 DEG C of identical outdoor temperature respectively, window aperture is
50% 1.1m/s, 1.9m/s, 2.5m/s arrives stream wind speed, which is simulated, to be calculated, and the different air-supply city wind speed Shi Yintai kindergarten buildings are obtained
Surrounding air speed (Fig. 8), interior CO2Concentration distribution of contours (Fig. 9).It is required according to indoor air quality, in conjunction with Interior Space
The distribution of gas quality parameter issues air quality signal to control panel by outdoor and interior sensor in the air-supply of different wind speed,
Through executing agency's adjustment and movable window fan, completing adjusting window aperture can reach effect of natural ventilation, such as room 7-9 and room
Between 16 when outdoor wind speed is less than 2.5m/s, need to expand window aperture on the basis of former 50% window aperture, remaining room exists
When outdoor wind speed is less than 1.9m/s, also needs to expand window aperture on the basis of former 50% window aperture, can just make room air
Quality reaches personnel's comfort index；If interior CO2Excessive concentration or temperature not in personnel's preference temperature scope, then control panel and
Executing agency automatically controls jointly and closes window, opens the new wind devices of variable air rate or air-conditioning equipment in mechanical equipment, using machine
Tool draft type makes indoor air quality reach personnel's comfort index.Each room window of difference arrives stream wind speed when southwestern wind direction
Aperture demand is specifically such as table 4.
Each space air quality table of the southwestern wind direction difference arrives stream wind speed of table 4
Note: CO2Concentration × expression can not (CO2Concentration>=1500ppm), o indicates still (1000ppm<CO2Concentration <
1500ppm), ◎ indicates best (CO2Nong Du≤1000ppm) temperature × expression can not (temperature>28 DEG C or temperature<18 DEG C), o
