Referring to Fig. 1, the natural ventilation automatic sliding window that embodiment adopts comprises outdoor temperature sensor 1, indoor and outdoor differential pressure pickup 2, centralized control unit 3, sliding sash opening controller 4, active window body 5 and fixed window frame 6; The outdoor temperature sensor 1 that wherein is arranged at outside window is transferred to detected outside temperature information in the centralized control unit 3 that is connected with outdoor temperature sensor 1; The described indoor and outdoor differential pressure pickup 2 sensing chamber's external and internal pressures of central authorities of edge that are installed on fixed window frame 6 are poor, and this information is transferred in the centralized control unit 3 that is connected with described indoor and outdoor differential pressure pickup 2; Place the input of indoor centralized control unit 3 to be connected with outdoor temperature sensor 1, indoor and outdoor differential pressure pickup 2 respectively, receive outdoor temperature sensor 1 and indoor and outdoor differential pressure pickup 2 signal transmitted, its output is connected with sliding sash opening controller 4, carries control information to sliding sash opening controller 4.
Last edge, the lower frame of described fixed window body 6 extend to the same side respectively; Sliding sash opening controller 4 is arranged on the extension of lower frame of fixed window frame 6, is connected the control information of receiving center control module 3, the aperture of control active window body 5 with active window body 5; Described active window body 5 moves along last edge extension, the lower frame extension of last edge, lower frame and the fixed window frame 6 of sliding sash opening controller 4 according to the opening information that receives.
The area of described fixed window frame 6 equates that with active window body 5 described active window body 5 can overlap, partially overlap or separate along the last edge extension of fixed window frame 6, when move the lower frame extension with the fixed window frame window.
Accordingly, control the method for above-mentioned natural ventilation automatic sliding window aperture, may further comprise the steps;
Centralized control unit 3 is made different disposal according to the temperature value that outdoor temperature sensor 1 and indoor and outdoor differential pressure pickup send:
(1) if outside temperature t
0＞30 ℃, centralized control unit 3 sends closes the control information of active window body 5 to sliding sash opening controller 4;
As outside temperature t
0More than 30 degrees centigrade, be generally the summer of comparison sweltering heat, the ventilation of should not having windowed should take to close window, uses air-conditioning temperature-reducing.So, this moment natural ventilation automatic sliding window aperture percentage O
pShould be zero, promptly close active window body 5, as shown in Figure 1;
The aperture percentage O of natural ventilation automatic sliding window
pBe horizontal sliding window aperture percentage, O when opening fully
p=100%, O when closing fully
p=0;
(2) if outside temperature is 20 ℃≤t
0≤ 30 ℃, the indoor and outdoor differential pressure information that the transmission of centralized control unit 3 analysis room's inside and outside differential pressure sensors 2 comes, if indoor and outdoor pressure differential deltap P be 0＜| Δ P|＜9, centralized control unit 3 sends aperture percentage O
pThe control information of=1-Δ P/9 is to sliding sash opening controller 4, if indoor and outdoor pressure differential deltap P is | and Δ P|＞9, centralized control unit 3 sends aperture percentage O
p=0 control information is to sliding sash opening controller 4;
In this temperature range, the optimum natural ventilation, the sliding sash area is only considered both sides magnitude of pressure differential and wind speed, the absolute value of indoor and outdoor pressure differential deltap P is in 9 handkerchiefs, and window place wind speed is generally less than 3m/s, relatively more suitable natural ventilation, and the absolute value of indoor and outdoor pressure differential deltap P is during greater than 9 handkerchiefs, wind speed can cause that greater than 3m/s indoor paper flies upward and stronger blowing feeling, should not window;
When room pressure during greater than pressure outside, Δ P is a malleation, otherwise Δ P is a negative pressure, and the unit of Δ P is Pa;
(3) if outside temperature is 12 ℃＜t
0＜20 ℃, centralized control unit 3 sends aperture percentage O
p=5% control information is to sliding sash opening controller 4;
In this temperature range, only need a spot of natural ventilation, satisfying the demand of human body, so the aperture percentage of natural ventilation automatic sliding window is fixed on 5%;
(4) if outside temperature is t
0＜12 ℃, centralized control unit 3 sends aperture percentage O
p=0 control information is to sliding sash opening controller 4;
When outside temperature is lower than 12 degrees centigrade, answer enhanced leaktightness, carry out building heat preservation, should close active window body 5 this moment, i.e. aperture percentage O
p=0;
The control information that sliding sash opening controller 4 sends according to centralized control unit 3 is regulated active window body 5 and is in buttoned-up status, as shown in Figure 1, or adjusting active window body 5 is in the part opening, as shown in Figure 2, or regulate active window body 5 and be in the complete opening state, as shown in Figure 3;
Natural ventilation automatic sliding window of the present invention is simple in structure, and element is less, greatly reduces cost.
Natural ventilation automatic sliding window of the present invention and control method thereof are controlled the sliding sash aperture according to indoor and outdoor pressure reduction, two parameters of outside temperature, and the control strategy science is clear and definite, for this energy-saving building technology of natural ventilation provides actual effective equipment.
It is wide that natural ventilation automatic sliding window of the present invention and control method thereof are suitable for the region, is specially adapted to obvious, the cold in winter and hot in summer area of four seasons difference.
