Description
技术领域 technical field
本实用新型涉及通风换气领域,具体涉及一种利用太阳能驱动的窗式新风机。 The utility model relates to the field of ventilation, in particular to a window-type fresh fan driven by solar energy.
背景技术 Background technique
近几年环境污染问题愈发严重,雾霾、沙尘暴在某些城市中出现的频率越来越高,给人们的身体健康带来了极大的威胁。为防止大气污染对人体健康造成的危害,人们采取了各种办法。使用室内空气净化器是很多人的选择,应用空气净化器虽然可以消除室内低浓度污染物,去除异味、灰尘、细菌,但却无法降低室内CO2含量和增加O2的含量,因而无法从根本上改善室内空气品质,送给人们真正新鲜的干净空气。提高室内空气品质最简单、最有效的办法,就是加强室内外的通风换气,不断向房间补充洁净的新风。 In recent years, the problem of environmental pollution has become more and more serious, and the frequency of smog and sandstorms in some cities has become higher and higher, which has brought great threats to people's health. In order to prevent the harm caused by air pollution to human health, people have taken various measures. The use of indoor air purifiers is the choice of many people. Although the application of air purifiers can eliminate indoor low-concentration pollutants, remove odors, dust, and bacteria, it cannot reduce indoor CO 2 content and increase O 2 content, so it cannot fundamentally Improve indoor air quality and give people really fresh and clean air. The simplest and most effective way to improve indoor air quality is to strengthen indoor and outdoor ventilation, and constantly add clean fresh air to the room.
通常的室内空气净化器与空调室内机比较类似,放置在室内,吸入房间的空气经过滤后在房间内循环。这种室内循环的空气净化器在室外空气较差时,开窗引入新风等同于“先污染后治理”,而且这种空气净化器滤网本身在室内,容易造成关机时滤网污染物脱落形成二次污染。对于净化器无法处理的某些污染物,会由于房间一直密闭而造成浓度升高。如果关闭门窗没有新风进入,三四个小时后空气含氧量降低,二氧化碳等含量增高。这种方式进风源没有得到有效的净化,不能从源头上保证进风的质量。 Common indoor air purifiers are similar to air-conditioning indoor units. They are placed indoors, and the air sucked into the room is filtered and circulated in the room. When the outdoor air of this kind of indoor circulation air purifier is poor, opening the window to introduce fresh air is equivalent to "pollution first and then treatment", and the filter screen of this air purifier itself is indoors, which is easy to cause the filter screen pollutants to fall off when the machine is turned off. Secondary pollution. For some pollutants that the purifier cannot handle, the concentration will increase due to the room being kept closed. If the doors and windows are closed and no fresh air enters, the oxygen content of the air will decrease after three or four hours, and the content of carbon dioxide and the like will increase. In this way, the air intake source has not been effectively purified, and the quality of the intake air cannot be guaranteed from the source.

Wherein, the solar photovoltaic DC power supply system includes a solar panel 1 and a battery pack, and the battery pack includes a first battery 4 and a second battery 5 . The fresh air introduction purification system includes a fresh air section and a return air section. The fresh air section includes the first primary effect filter 11, the electrostatic precipitator 10 and the cross-flow fan 9 arranged in sequence. The air duct of the fresh air section is connected indoors and outdoors; the return air section It includes a second primary filter 12 and a regulating air valve 13 . The control system includes a solar controller 3 , an AC/DC converter 7 and a DC voltage converter 6 .
太阳能控制器3用于控制太阳能电池板1对第一蓄电池4和第二蓄电池5充电。交直流变换器7的输入端连接蓄电池组的输出端,其输出端连接贯流风机9。直流电压变换器6的输入端连接蓄电池组的输出端,其输出端连接静电除尘器10。调节风阀13的 出风口连接新风段,并设置在第一初效过滤器11和静电除尘器10之间。调节风阀13选用电动调节风阀,并通过控制系统控制其开闭。太阳能光伏直流电源系统还包括用于对蓄电池组进行充电的充电模块2,该充电模块2的输入端连接公共电网,其输出端连接蓄电池组的输入端。 The solar controller 3 is used to control the solar panel 1 to charge the first storage battery 4 and the second storage battery 5 . The input end of the AC-DC converter 7 is connected to the output end of the battery pack, and the output end is connected to the cross-flow fan 9 . The input end of the DC voltage converter 6 is connected to the output end of the battery pack, and its output end is connected to the electrostatic precipitator 10 . The air outlet of regulating damper 13 connects fresh air section, and is arranged between the first primary effect filter 11 and electrostatic precipitator 10. Regulating damper 13 selects electric regulating damper for use, and controls its opening and closing by control system. The solar photovoltaic direct current power supply system also includes a charging module 2 for charging the battery pack. The input end of the charging module 2 is connected to the public power grid, and the output end is connected to the input end of the battery pack.
其工作原理为:太阳能光伏直流电源系统将光能转换成电能以直流电的形式轮流对第一蓄电池4和第二蓄电池5进行充电,蓄电池组给新风引入净化系统提供电能。具体为,第一蓄电池4或第二蓄电池5输出的直流电进入到交直流转换器7中,直流电被转换为交流电带动贯流风机9转动,同时直流电压变换器6也将第一蓄电池4或第二蓄电池5输出的直流电升压后供给静电除尘器10使用;室外污浊空气首先通过浸渍有活性氧化物的第一初效过滤器11,随后新风通过静电除尘器10,静电除尘器10对新风中的PM2.5及PM10等颗粒物进行静电吸附,大幅降低新风中的颗粒物浓度,最后新风在贯流风机9的作用下送入室内。另一方面,在实现新风引入净化的同时,还可以控制调节风阀13的开度,使一部分室内回风混入到新风中,这样可以大大减少新风段的工作量,大幅节约电能。当调节风阀13完全开启并关闭新风段新风入口时,此时新风机则转化为室内空气净化器,室内空气依次经过第二初效过滤器12、调节风阀13、静电除尘器10后,通过贯流风机9将净化后的空气重新注入室内。 Its working principle is: the solar photovoltaic DC power system converts light energy into electrical energy and charges the first storage battery 4 and the second storage battery 5 in turn in the form of direct current, and the storage battery pack provides electrical energy for the fresh air introduction purification system. Specifically, the direct current output by the first storage battery 4 or the second storage battery 5 enters the AC-DC converter 7, and the direct current is converted into alternating current to drive the cross-flow fan 9 to rotate. At the same time, the DC voltage converter 6 also converts the first storage battery 4 or the second The DC power output by the second storage battery 5 is boosted and supplied to the electrostatic precipitator 10 for use; the outdoor dirty air first passes through the first primary filter 11 impregnated with active oxides, and then the fresh air passes through the electrostatic precipitator 10, and the electrostatic precipitator 10 is used for the fresh air. Particles such as PM2.5 and PM10 are electrostatically adsorbed to greatly reduce the concentration of particles in the fresh air, and finally the fresh air is sent into the room under the action of the cross-flow fan 9. On the other hand, while realizing fresh air introduction and purification, the opening degree of the damper 13 can also be controlled and adjusted so that part of the indoor return air can be mixed into the fresh air, which can greatly reduce the workload of the fresh air section and greatly save electric energy. When the regulating air valve 13 is fully opened and the fresh air inlet of the fresh air section is closed, the fresh air fan is converted into an indoor air purifier, and the indoor air passes through the second primary filter 12, the regulating air valve 13, and the electrostatic precipitator 10 successively. The purified air is reinjected into the room through the cross-flow fan 9 .
本实用新型的新风机在工作时,太阳能控制器3能够根据第一蓄电池4和第二蓄电池5的电压对蓄电池组进行充电控制:当第一蓄电池4电压达到要求而第二蓄电池5电压较低时,仅对第二蓄电池5充电;反之则仅对第一蓄电池4充电。在阳光不足或没有阳光且第一蓄电池4和第二蓄电池5的电压都较低时,可通连接公共电网的充电模块对蓄电池组进行充电,保持系统的平衡稳定的运行。 When the fresh air blower of the present utility model is working, the solar controller 3 can charge the storage battery pack according to the voltages of the first storage battery 4 and the second storage battery 5: when the voltage of the first storage battery 4 reaches the requirement and the voltage of the second storage battery 5 is relatively low , only the second storage battery 5 is charged; otherwise, only the first storage battery 4 is charged. When the sunlight is insufficient or there is no sunlight and the voltages of the first storage battery 4 and the second storage battery 5 are both low, the charging module connected to the public power grid can be used to charge the battery pack to maintain a balanced and stable operation of the system.
以上所述仅是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。 The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
