  • Little White Knowledge Class: Installation Guide for Fresh Air System
  • Published: 2019-10-16 Views: 51 times Author: Ka-generation ventilation

    I have encountered many fresh air users who have encountered this problem: why the fresh air system I bought at home has a large amount of air and sufficient functions, but the effect experience is not good when I use it, and it does not meet expectations. This may be because there is a problem with the fresh air installation, and the quality of the after-sale installation will also affect the overall function and effect of the fresh air system. Below, I will summarize the installation details and precautions of the fresh air system for everyone!

    新风系统安装

    1. Install according to the design drawing

    The main point here is that you must install the installation plan of the design drawing to install. Many users obviously get the fresh air installation drawings, but they always like to change it here, and there are changes. Often, the more places that are changed, the greater the chance of affecting the fresh air effect. .

    Now many fresh air system vendors will provide fresh air design drawings. After selecting the fresh air system, users only need to send the area, structure, and floor plan of the house to the fresh air designer. The fresh air designer will use the data to locate the fresh air fan and the layout of the ducts, air outlets, and peripheral facilities. Here it is emphasized that during the actual installation of the fresh air system, it must be installed in strict accordance with the design drawings, to ensure that each link of the fresh air system is installed in place, and to cooperate well with the overall interior decoration.

    2. Host installation

    Install according to the installation design drawing of the fresh air system . The first step is to install the main unit. The main unit is generally installed in the balcony, kitchen or bathroom ceiling. The main unit is installed in the place where the required air duct length is the smallest to reduce pipeline resistance. The main unit needs to be fixed firmly with expansion screws, so as not to cause the machine to shake during operation, and the internal motor and fan blades will make a lot of noise, affecting the air volume and effect. It should also be noted that the suspended ceiling below the machine uses a movable ceiling or has an access opening, which is convenient for the later maintenance of the machine, replacement and replacement of parts and repairs.

    3. Pipeline installation

    波纹管、 PVC 管、铝箔软管、镀锌铁皮风管。 There are many choices of pipes for the fresh air system. The commonly used pipes are PE bellows, PVC pipes, aluminum foil hoses, and galvanized iron ducts. According to the use environment, place, and needs, select the appropriate pipeline for installation.

    The installation of the pipeline must not have too many errors. Try to keep it horizontal and vertical, and also ensure that the inner diameter of the pipe is clean and free of debris. During the installation, the positions of the air outlet, direction and diameter of the pipeline must comply with the design drawings, and the installation of the pipeline must be supported by cranes.

    4. Host-to-pipe connection

    主机和管道接口处应该采用防火帆布和铝箔连接, 防火帆布和铝箔 不可以扭曲、破损、不能皱起,必须要平整,接缝要粘包紧密,不能漏风,连接处需用扎带固定。 Attention should be paid to the connection between the host and the pipeline : 1. The interface between the host and the pipeline should be connected with fire-resistant canvas and aluminum foil . , The connection needs to be fixed with a cable tie.

    5.Air outlet installation

    Air inlet installation

    Before installing the air inlet, be sure to choose the installation location, it is best to install under the window sill or a relatively easy installation location, never install it in a blind spot. The correct installation position can make the indoor dirty air form a circulation system with the fresh air, so that the indoor air can be circulated and circulated. When installing the air inlet , it should be firm and stable.

    Exhaust vent installation

    For the toilet air outlet, it is best to choose the installation position above the toilet. For indoor air outlets , the best installation position is above the door frame. This installation method makes the exhaust air and fresh air form a ventilation circulation system, so that the indoor air can be well circulated and the indoor air is more fresh. The exhaust air outlet must be firmly installed. It should be noted that the air outlet should be close to the roof or wall.

    6. Precautions during installation of fresh air system

    是一个非常重要的环节,对于后期的使用效果有重要的影响,所以在安装过程中需要对各个环节加强注意: The installation of the fresh air system is a very important link, which has an important impact on the later use effect. Therefore, it is necessary to pay attention to each link during the installation process:

    (1) Be sure to construct according to the fresh air design drawings, and you cannot modify it without permission. You must ask the installation design engineer for the modification.

    (2) Emphasis should be placed on the pipelines installed with fresh air systems, and hard pipelines should be used first;

    (3) When arranging pipelines, it should be considered as far as possible to reduce the loss of air volume;

    (4) According to the customer's needs, try to meet the owner's requirements for the height of the indoor ceiling;

    (5) During the installation process, it may be necessary to punch holes in the wall. At this time, when choosing the installation location, the overall structure of the room cannot be destroyed at the cost, and the wall should be protected from damage.

    (6) It is also important to choose the location of the air outlet. The location of the air outlet of the fresh air system should be selected reasonably, and the relationship between the location of the air outlet and the return air outlet should be handled to avoid mutual influence.

    The installation of the fresh air system needs to pay attention to all aspects, and must not be careless in pursuit of beauty, speed and effort. For fresh air to work well, installation is important! !! !!
