Gravity-flow ventilation and force ventilation mode convert purpose, make the CO of room air2Concentration and temperature parameter reach needed for person works
It is required that.Wherein each room boundaries condition such as table 2.
Boundary condition table between 2 each side of table
Operating condition one:
Such as Fig. 3, the city Ping Yintai kindergarten building is faced to Hangzhou and carries out identical wind speed, 27 DEG C of identical outdoor temperature respectively
Southwest and the simulation of northwest wind direction calculate, and are respectively 20%, 50% and 100% by control window aperture.Southwestern wind direction is obtained to send
Indoor air temperature (Fig. 4), the CO of different window apertures in the city Feng Shiyintai kindergarten building2Concentration distribution of contours (Fig. 5)
And indoor air temperature (Fig. 6), the CO of the interior different window apertures of the northwest city wind direction Shi Yintai kindergarten building2Concentration isopleth point
Cloth (Fig. 7).It is required according to indoor air quality, in conjunction with indoor air quality parameter concentration and distribution, is passed through in different wind directions
Outdoor and interior sensor issues air quality signal to control panel, and through executing agency's adjustment and movable window is fanned, and completes to adjust
Window aperture can reach effect of natural ventilation, and room 7-9 and room 12,16 window aperture of room need to reach when such as southwestern wind direction
100%, remaining room window aperture is at least up to 50%, and room 1-6 when the wind direction of northwest, 20% window aperture has met CO2It is dense
Degree and temperature requirement；Except room 16 need to be using remaining 50% window aperture of room in addition to force ventilation；If interior CO2Concentration mistake
Not in personnel's preference temperature scope, then control panel and executing agency automatically control jointly closes window, opens machine high or temperature
The new wind devices of variable air rate or air-conditioning equipment in tool equipment, using force ventilation mode, room 16 when such as northwest wind direction, full open window
Family can not make indoor air quality reach personnel's comfort index, need to use force ventilation.Each room window is opened when the wind direction of northwest
Degree demand specifically such as table 3, when southwestern wind direction each specific window as corresponding to 27 DEG C of outdoor temperature in table 5 of room window aperture demand
Family aperture demand.
3 each space air quality table of northwest wind direction different window family aperture of table
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
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
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 three:
Such as Fig. 3,16 DEG C, 23 DEG C, 27 that the city Ping Yintai kindergarten building carries out wind speed outside identical chamber respectively are faced to Hangzhou
The simulation of DEG C wind-warm syndrome calculates, and the indoor air temperature for obtaining different window apertures in the city different wind-warm syndrome Shi Yintai kindergarten building is equivalent
Line is distributed (Figure 10, Figure 11, Figure 12).It is required according to indoor air quality, in conjunction with indoor air quality parameter distribution, in different wind
Air quality signal is issued to control panel by outdoor and interior sensor when temperature air-supply, through executing agency's adjustment and movable window
Fan is completed to adjust window aperture to be that can reach effect of natural ventilation, such as room 1-11 and 13-16 at 16 DEG C of outdoor temperature, be reached
50% or more window aperture just can guarantee the requirement of CO2 concentration, and can substantially meet temperature requirement；Wherein room 12 suggests closing
Window, the force ventilation for taking air-conditioning heating, for keeping the temperature and improving air quality；Interior is substantially met at 23 DEG C of outdoor temperature
Temperature requirement, but room 7-9 and room 12,16 window aperture of room need to reach 100%, remaining room window aperture is at least up to
To 50%, it is just able to satisfy indoor CO2Concentration requirement；With 23 DEG C of outdoor temperature at 27 DEG C of outdoor temperature, room 7-9 and room are removed
12, room 16 needs outside aperture 100%, remaining room needs 50% window aperture.If interior CO2Excessive concentration or temperature be not in personnel
In preference temperature scope, then control panel and executing agency automatically control jointly and close window, open the variable air rate in mechanical equipment
New wind devices or air-conditioning equipment make indoor air quality reach personnel's comfort index using force ventilation mode, room at such as 16 DEG C
