What should be paid attention to in the installation of the fresh air system, and the precautions fo

First of all, you have to understand that fresh air is not a filter, not a filter, its first task and main task is to ventilate.

Second, you need to understand several common patterns of fresh air:

1. Home decoration is common in two-way flow with heat.

2. One-way flow air supply type (exhaust air is solved by the ventilation fan or bath bomb in the bathroom).

3. One-way flow exhaust type, only exhaust air, no air supply design.

Third, understand your needs – what exactly are you going to do? Or what do you want to do in different areas of your house? How many people live? Are there any patients? Do you have children? Do you smoke?

For example, if you have designed a full-heat fresh air system for the whole house, but you have a tea room or study at home, and you still have the habit of smoking, then you should install an independent large-volume exhaust device in the tea room or study;

If you are not new and have a budget that you don't have, but you have children at home, you can consider putting a wall mount in your child's room.

For example, if your home is a villa and a jump, you must know what the function of each floor is, and the design principle is to first ensure the air change in the area with frequent human activities, on this basis, you can consider whether each floor has a machine or two floors to share one, which involves whether your service provider has experience in doing jumper pipeline installation; If you have a basement, then think about what the basement does? If it is only for general storage, it is possible to make a large air volume exhaust fan, the principle is that there is no one living in the area, the requirements for heat ** are not so high, simply consider the problem of exhaust and ventilation.

What matters should be paid attention to when installing an indoor fresh air system in home decoration?

What are the precautions for the installation of the fresh air system?

First, it is necessary to keep the position of the main engine of the fresh air system horizontal and firm. If it is a ducted fresh air system, it is generally installed on the ceiling of the kitchen or bathroom, which should be determined according to the actual situation on site.

Second, the fan and air duct of the fresh air system should be selected according to the actual installation situation, the hose or hard pipe should be selected, which is generally a combination of hose and hard pipe, and a single pipe should not be used indiscriminately, and the pipe diameter should be consistent with the size of the fan inlet and outlet. If a hose is used, it should be installed with a certain degree of tightness to avoid twisting and deformation.

Third, in the installation process of the pipeline-type fresh air system, if you encounter a wall or beam that is not allowed to open in the property, you should use a lintel, and at the same time, when the pipeline needs to change direction, the angle should be greater than 90 ° as much as possible, and the pipeline laying should be as short as possible, and the laying of useless pipes should be refused, because the longer the pipe, the greater the wind loss at the end.

Finally, the fresh air outlet and the exhaust air outlet are generally installed diagonally to ensure the maximum distance between the two air outlets, so as to avoid the fresh air that has just entered the room from being discharged directly from the exhaust outlet. At the same time, rain caps should be added to the air outlets exposed to the outdoors, and they should be effectively installed to avoid direct rainwater backflow!

If you have purchased a fresh air system at home, the next step is the installation step. What are the precautions for the installation of the fresh air system? PChouse will take you to find out.

1. The installation location of the household fresh air system.

From the perspective of space, aesthetics, noise, etc., the host of the household fresh air system is best installed in a non-residential area. Such as bathrooms, kitchens, garages and laundry rooms on the ceilings. Does not take up extra space, hidden; It does not affect the interior aesthetics; And the noise is low, which does not affect the rest.

2. Installation space of household fresh air system.

Before installation, it must be ensured that there is enough operating space, and it is convenient for future maintenance and cleaning, and it should be considered that 500 500mm (the specific size is based on the size of the host) access port should be reserved in front of the main engine or above the ceiling, so as to facilitate the maintenance of the main engine in the future. For the sake of aesthetics, many families like to "hide" the fresh air system, which is inconvenient for subsequent cleaning.

3. The installation position has air supply conditions.

Strictly speaking, the distance between the outdoor air supply and exhaust outlets of the household fresh air system is as far away as possible, the horizontal distance should be more than 10 meters, and the vertical distance should be more than 3 meters, but this is difficult to do in the residence, but it is necessary to ensure a distance of more than 1 meter; The bottom of the air inlet should not be less than 2 meters away from the outdoor ground, and when the air inlet is arranged in a green area, it should not be less than 1 meter, and it should be far away from the smoke exhaust pipe of the gas water heater of the neighbor's house.
