Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is that the master of invention looks schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the passive type ventilating system of a kind of science and technology center building, comprises building frame main body 1, and described building frame main body both sides are provided with air-supply passage 2.Described air-supply passage is inclined-plane setting, allows building possess preferably attractive in appearance and unique; Between air-supply passage, be several cubicles, between cubicle, by ventilating opening 3, be communicated with, described ventilating opening is provided with carbon dioxide inductor and temperature sensor.By corresponding sensor, realized corresponding parameter in building is monitored, building frame main body bottom is provided with the basement 5 with air inlet, and described building frame main body upper end is provided with the chimney being communicated with cubicle 7.Described building frame main body middle part is provided with ventilation trunk 6, and ventilation trunk upper end is directly communicated with chimney 4.Conventionally the temperature difference on basement and upper strata is larger, just between levels, realizes flowing of air, and fresh air is entered by air inlet, then is sent by chimney, realizes the air in cubicle is substituted.In use, when arbitrary room indoor carbon dioxide concentration surpasses maximum limit, increase the unlatching of inlet and outlet to keep IAQ.If time delay or gas concentration lwevel, lower than lower limit, as 500ppm, increase air inlet quantity again, reach second increment level.Arbitrary room gas concentration lwevel is during lower than lower limit, the air inlet of closing this room, but air outlet continues to be held open.Above and below gas concentration lwevel restriction, time delay and air inlet are opened quantity and are regulated voluntarily by user.If need to heat in using, fresh gas flow will be controlled at floor level to maintain acceptable gas concentration lwevel.Particularly winter, due to the huge stack effect that indoor/outdoor temperature-difference causes, minimum even if ventilation orifice keeps, the air-flow that enters room also can be a lot.Provide quantitatively fresh air to maintain carbon dioxide level, mechanical ventilation system is operated more energy-conservationly, and all outside air port that passive type ventilates is closed prevent that cold wind from entering completely, if cold wind enters, for maintaining the hot comfort of indoor environment, heat, can cause energy waste.Do not need in transition season and summer to heat, the control of ventilating opening is completely according to temperature sensor (building interior air-flow is unobstructed, and gas concentration lwevel is no longer a problem).For reducing indoor high temperature, the throughput that passive type ventilates can be large as far as possible (avoid air-flow not smooth).
In building use procedure, temperature constantly raises, and because inside and outside heat obtains, can exert an influence to indoor air temperature.When indoor temperature surpasses ventilation refrigeration value (non-mechanical refrigeration in summer value), as 24 ℃, temperature controlled ventilation refrigeration mode is activated.These settings are regulated voluntarily by user but must be greater than the value of heating.Air inlet is opened by different increments, while opening by different increments, will have certain time-delay, and air outlet is opened after air inlet is opened again.If indoor air temperature continue to raise, finally reach buoyancy-driven and ventilate in the time of cannot introducing enough newly the temperature of wind, just force ventilation is opened.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
