Some people think that buying a fresh air system is a waste. Opening the window ventilation does not cost money, so why spend money and energy to install the fresh air system? First of all, when the air quality outside is bad, PM2.5, dust, automobile exhaust, industrial exhaust gas will enter your house. In winter or summer, air conditioning has been turned on, opening windows is not available; If living in high floor, it is not secure for a family with children. In conclusion, each household has its own special situation, if open window has other hidden dangers, a fresh air system of course, is needed to achieve ventilation

When outdoor fresh air is introduced into the pipeline, insulation pipes should be used to prevent condensation on the outer wall of the pipeline caused by temperature difference in winter when the external temperature is lower than 0℃.

Wall-mounted fresh air system is generally one-way air delivery by the micro-positive pressure principle: in the case of window closed, when it forces the filtered external fresh air inside, indoor air pressure will be slightly higher than the outdoor, and then the original indoor polluted air constantly squeeze out through the door, and finally through the toilet and kitchen air vents . This can achieve ventilation effect, reduce indoor PM2.5, and eliminate carbon dioxide and formaldehyde.

But in the advertising map made by some manufacturers who claims their wall-mounted ventilation system can achieve the whole house purification, the air of each room is squeezed out through the window gap. It is important to know that users who generally choose ventilation system tend to use highly sealed windows, otherwise noise and tiny particles can also come in through the cracks. In this case, dirty air is not easy to get out of a closed room without a vent. Any room that does not belong to the negative pressure area, clean air will not flow in, but will pass through the bathroom and kitchen and come out from the vents, so that the whole house cannot be purified.

So weather wall-mounted fresh air system can perform the whole house purification depends on the room type, the position of the air vent and window sealing. If you are not sure about your home, you can make an appointment to survey and measure the best product for you.

At present, there are two main ways of filtration, electrostatic dust collection and HEPA filtration

Fresh Air system is that the fresh air unit, purifier, fresh air pipe and air vent introduce the outdoor fresh air into the room, after purification treatment, and then convey the fresh air through the pipe to each room. At the same time, the dirty indoor air with low content is discharged from the outdoor to ensure the stability of indoor pressure (micro positive pressure).

It can be calculated in two ways:

(a), the number of ventilations: the number of home ventilation generally select 0.75-1 times.

(b), fresh air volume per capita: 30-50 cubic meters of fresh air per hour.

For example: a 15 square master bedroom with 2.5 meters high floor. According to method 1, it is calculated to get the fresh air volume per hour 15×2.5×1=37.5 cubic meters; while according to method 2 calculation, the number of people in the master bedroom according to 2 people, the required hourly fresh air volume of 2×30×60 cubic meters two calculation results, Select a larger one as the basis for selection, i.e. the room requires 60 cubic meters of fresh air volume per hour. The rest of the room is also calculated according to this method, the sum of the total air volume of each room is less than or equal to the maximum air volume of the selected ventilation unit

The air vent is the terminal device of the ventilation system introducing outdoor air into the room, and the source of blowing out or bringing in in the air supply system. The air pipe is an important device for conveying fresh air, and all the vents need to be closely connected with the air pine to ensure the normal operation of the whole system. The composition of the ventilation system: the ventilation motor-air pipe-air vent, all three are indispensable.

Yes, the fresh air unit has a filter.

The pressure generated by the impact of the pipe wall due to irregular movement of air molecules is called “static pressure”. Then the purpose of setting up the static pressure box is to obtain static pressure. When the air is conveyed through the pipe, in order to make the air pressure of the pipe consistent, it is necessary to establish a static pressure box, so that the dynamic pressure is all converted into static pressure, and then evenly distributed in the air ducts. Similarly, when the air is returned through the pipe, a static pressure box is also required to allow the air to be fully mixed.

Some single ducts of the air supply pipe is also installed static pressure box for noise reduction by the principle that the air into the static pressure box speed significantly slower, the wind will be reduced. The function of the static pressure box is to provide uniform pressure for each branch line, theoretically the static pressure inside the static pressure box is equal, that is to say, the internal flow rate of the static pressure box is zero, which can be met by the fact that the static pressure box volume is infinite, which is impossible in the project. Generally, the air speed within the box can be controlled below 2m/s, or can be greatly reduced relative to the wind speed of the inlet and outlet duct.

Yes, but there is no fresh air in the room, the reduction of indoor oxygen content, people will feel faint.

It may, if set-up incorrectly or not maintained properly. TAK AIR fresh air system is designed to avoid secondary contamination and our professional maintenance team is trained to ensure it.

The fresh air purification system in TAK AIR is an independent air treatment equipment system consisting of the air supply system and the air return system. At the entrance of the external air, the clean air is brought into the room by the purification module through the decomposition, impact, adsorption, blocking and sterilization of pollutants, and the dirty air is discharged through the exhaust pipe or micro-positive pressure. At the same time, regular maintenance is carried out twice a year, which will never cause secondary pollution.

There are two main sources of noise in the fresh air purification system: a, noise from fan operation in fresh air main engine, the noise generated by the return of the air current shock, friction pipe and the air vent.

a.) The host of the fresh air system is a volute-type centrifugal DC motor fan. The fan is designed with reasonable impeller Angle according to the air flow mechanics. During operation, there is no mechanical friction and the reasonable blade shape line reduces the noise to the minimum; The optimized impeller reduces the axial force to the minimum degree. With an efficient impeller, and after the static and dynamic balance correction, the whole machine runs smoothly. Without any vibration damping device, the bearing amplitude is relatively small. It features small loss, high efficiency, large air volume, small vibration, low noise and other advantages. Compared with AC, DC motor has better performance in energy saving and environmental protection.

Are you still worried about its noise? Obviously not necessary.

b.) a professional design team and standard construction team is available to the installation of TAK AIR fresh air purification system.

Noise reduction scheme 1: Air divider: installed in the fresh air coupling air outlet. Advantages: 1. The air volume is evenly adjustable; 2. Reduce the noise of the tuyere

Noise reduction scheme 2: silencer: a 1-meter-long silencer pipe is installed at the fresh air main outlet and the end air outlet to reduce the noise of the air vent;

Noise reduction scheme 3: Use silencer cotton: a layer of glass fiber soundproof cotton about 1.5-3.5cm thick is pasted inside the fresh air main engine box to effectively reduce the noise of the host operation.

TAK AIR fresh air system include excellent-quality host, professional design team and standardized construction team, which can secure the use effect of the fresh air system of TAK AIR, and reduce noise as far as possible.

Yes, because the source of pollution first through the filter for filter and antisepsis. If the filter doesn’t be replaced in half a year, antibacterial effect will become worse. Although the conveyed fresh air is clean, in the rainy season, the filter cannot block brume. So the growth of bacteria is inevitable, do not change in long-term will cause secondary pollution.

It generally depends on the specific situation. for air distribution, it is better to have more supply air points, but more supply air points will lead to the increase of pipe abnormity and also increase the resistance of the whole system. However, more air supply points will lead to more abnormity of pipe and increase the resistance of the whole system.

So it depends.

Not necessarily, it is subject to availability. It is generally recommended to install in the bathroom or kitchen. It’s fixed with hanging wire and pull explosion. Just as the expansion screw works, the host has a hanging hole, gaskets should be added above and below the hoisting hole. When it’s level, tighten the upper and lower nuts and the customer is advised to add a shock cushion below. The access port is generally left on the terminal side with size of 450×450

Ceiling space to meet the installation height requirements, distance from the wall to meet maintenance requirements, noise impact requirements are not high, convenient indoor pipe, the supervisor convenient access to the outdoor, the host location needs to be placed in the bathroom or kitchen and other non-functional rooms near the outdoor, to meet the noise requirements.

Ceiling space meets the installation height requirements, distance from the wall meets maintenance requirements, noise impact requirements are not high, convenient indoor pipe layout, the convenient access of main duct to the outdoor, the host location needs to be placed in the bathroom or kitchen and other non-functional rooms near the outdoor to meet the noise requirements.

Rough room or secondary decoration of the house is more convenient

有人觉得购买新风系统就是交智商税，开窗通风不要钱，为啥要花那么多钱那么多精力装新风系统。首先外面空气质量不好的情况下，PM2.5、灰尘、汽车尾气、工业废气会进到家里。遇到冬天或夏天，已经开了空调，开窗通风不太现实；如果住在高层，家里有小孩，开窗还不安全……总之，每家每户都有自己的特别情况，如果开窗通风有其他隐患，当然需要新风机来实现通风了。

室外新风引入管路，为防止在冬季外界气温低于0℃情况下，管道存在温差而产生管道外壁结露现象，应使用保温管道。

壁挂式新风机一般是单向送风的，利用的是微正压原理：在窗户封闭的情况下强制送入过滤好的外界新鲜空气，室内的气压会略高于室外，然后室内原有的污染空气不断通过门缝挤压出去，最终通过位于洗手间和厨房的排风口自然被挤压到室外。这样可以实现通风换气效果，降低室内PM2.5、排除二氧化碳和甲醛。

但有些号称壁挂式新风机能做到全屋净化的厂家的宣传图里，每个房间的空气是经过窗户的空隙挤压到室外。要知道一般选择新风机的用户往往会搭配密封性很高的窗户，不然噪音和微小颗粒也可以从缝隙中进来。这样的话，脏空气其实并不容易从没有排风口的密闭房间出去。凡是不属于负压区的房间，干净的空气也不会往里流通，而是会经过卫生间和厨房，从排风口出去了，这样是做不到全屋净化的。

所以壁挂式新风机能不能做到全屋净化还是要看房型、排风口的位置及窗户密封性。如果您对自己家的情况还不是很确定，可以预约上门勘察及测量，为您选择最适合产品。

目前主要方式有两大过滤方式，静电集尘和HEPA过滤

新风系统是通过新风机组，净化器、新风管道和风口，将室外新鲜空气吸入室内，经过净化处理后，再把新鲜的空气通过管道输送到每个房间，同时将室内污浊、含量低的空气排出室外，保证室内压力的稳定（微正压）

可按两种方法计算：

（a）、换气次数：家装换气次数一般选择0.75-1次。

（b）、人均新风量：每人每小时30-50立方的新风量。例如：一15平方主卧室，层高2.5米，按照方法1计算得到每小时新风量15*2.5*1=37.5立方，按照方法2计算时，主卧室内人数按照2人计算，则需要的小时新风量为2*30=60立方两种计算结果，选择较大的一个作为选型依据，即该房间每小时需要60立方的新风量。其余房间也按照该方法计算，各房间总风量之和小于等于选择的新风机组的最大风量。

风口是新风机引入室外空气到室内的末端装置，是送风系统中吹出或引入的源头。风管是输送新风的重要装置，所有的风口都需要与风管紧密连接，才能保证整个系统的正常运行。新风系统的组成：新风机-风管-风口，三者缺一不可。

带，新风机组内有过滤的滤网。

由于空气分子不规则运动而撞击管壁所产生的压力称“静压”。那么建立静压箱的目的就是获取静压。在多风管送风时，为使各风管的风压一致，则需要建立静压箱，使动压全部转化为静压，再平均分配到各风管中。同理，在多风管回风时，也需要静压箱，可使空气充分混合。有些单风管的送风管道也装静压箱，目的是利用静压箱消声，原理是空气进入静压箱内速度明显变慢，风声会减小。静压箱的作用是为各分支管路提供均匀的压力，从理论上说静压箱内部静压处处相等，也就是说静压箱内部流速处处为零，要满足这点的条件是静压箱体积无穷大。在工程项目中这是不可能的，一般箱内风速可控制在2m/s以下，或相对于进出风管风速有大大下降即可。

不会。一般的新风设备会造成二次污染。

新风净化系统的噪音来源主要有两个： a、新风主机中风机运转噪音b、送回风气流冲击和摩擦管道、风口产生的噪音。

a、泰棵新风净化系统主机是采用蜗壳式离心DC直流电动机风机。风机根据空气流力学采用合理叶轮角度设计，运行时，无任何机械摩擦，合理叶片形线使噪声降为最低；优化设计的叶轮使轴向力减小到最低程度，且有高效的叶轮，并经静动平衡校正，使整机运行平稳，在不加任何减振装置的情况下，轴承振幅比较小；具有损耗小，效率高，风量大，振动小，噪音低等优点；性能优越直流电机的直流相对于交流比较节能环保。

你还担心它的噪音吗？显然没有必要。

b、泰棵新风净化系统安装时有专业化的设计团队和规范施工团队。

噪音降低方案1：分风箱：安装在新风净化耦合出风口。优点：1.风量分流均匀可调节；2.可以降低风口的噪音；

噪音降低方案2：消音管：在新风主机出口和末端风口分别安装一段1米长的消音管，以降低风口的噪音；

噪音降低方案3：使用消音棉：在新风主机箱内贴一层玻纤隔音棉约1.5-3.5厘米厚，有效减小主机运行时的噪音。

泰棵新风净化系统具有产品品质要过硬的主机、专业化设计团队和规范施工团队，能够保证泰棵新风净化系统使用效果的情况下，尽量降低噪音量。

需要、因为污染源首先通过过滤网过滤抗菌、如果半年不更换滤网、抗菌效果就会变差。虽然新风送进来的都是洁净的新风、但遇到雨季、滤网不能阻挡水气、所以细菌滋生是必然的、长期不更换就会二次污染。

一般根据具体情况而定，对于气流组织而言是送风点多会好，但是送风点多会造成管道异形件的增加，也会增加整个系统的阻力。所以要看情况而定。

不一定，视情况而定，一般建议装在卫生间或厨房。固定用吊丝和拉爆，和膨胀螺丝原理一样，主机上都有吊装孔，吊装孔上下要加垫片，水平时上下螺母拧紧就可以了，下面建议客户加一减震垫。检修口一般留在接线侧450*450大小即可。

吊顶上部空间满足安装高度要求、离墙距离满足检修要求、对噪声影响要求不高、方便室内管路布管、主管方便接出室外、主机位置需放在卫生间或厨房等靠近室外的非功能性房间，以满足噪音要求。

毛坯房或者二次装修的房子较为方便些
