What do I need to pay attention to when installing a fresh air system?

When drilling, a lot of water is used. If there is no water, the drill bit will become very hot, will jam in the wall, or will become dull, so the installation equipment must be connected to the water pipe to continuously deliver water to the drill bit. As soon as the hole is drilled, the water will flow out of the hole and through the waterproof cover into the dirty bucket.

The water flows from a turquoise bucket to the drill bit, and then through the waterproof hood to the dark blue dirty bucket. When drilling, a lot of water is used.

After punching the holes, the master put the installation template on the wall, laid the template flat, and then carved the position of the installation screws on the wall. In this way, when the machine is suspended, it is ensured that its air inlet is just facing the air duct.

The fresh air system brings high-quality indoor air quality to people, and is widely used in today's seriously polluted air. However, many users will have various problems when using the fresh air system, which makes the use of the fresh air system unable to achieve the expected results. The reason for this is that there are many problems in the installation of the fresh air system.

So, how to install the indoor fresh air system in order to achieve the user's expected use goals? To install an indoor fresh air system, you must first determine the installation time. Generally speaking, the installation of indoor fresh air system is often carried out during indoor decoration, mainly for the following reasons:

It can be synchronized with the decoration, which can be well combined with the interior decoration, which can not only maintain the installation effect of the fresh air system, but also make the indoor decoration not damaged; Installed in the interior decoration, the fresh air system with the interior decoration, showing the beauty of the decoration, at the same time, the fresh air system shows the luxury of the interior decoration, and improves the grade of the interior. The installation of a fresh air system indoors is, of course, to make the air in the indoor environment fresher and cleaner, and to improve the indoor air quality. Therefore, in order to ensure the good use effect of the fresh air system, the installation of the air outlet is also particularly important, so as to ensure that the indoor air is fresher and cleaner.

The tuyere of the fresh air system needs to be installed in a place where the outdoor air is cleaner, so as not to affect the indoor air with dirty gases, which can make the air entering the room cleaner. In addition, it is necessary to do a good job of waterproofing measures at the air intake device. As for the location of the air suction in the kitchen, it should also be away from the stove.

The fresh air system brings high-quality indoor air to people, but in order to truly enjoy this high-quality indoor air, all related issues need to be paid attention to during the installation process. Today, the fresh air system is increasingly accepted and used by people, and only by paying attention to installation can it be better used by people.

The ventilation duct of the fresh air system will affect the use effect of the fresh air system, and it is also necessary to pay considerable attention to the installation of the ventilation duct, and the installation of the ventilation duct should be installed in strict accordance with the design drawings. In addition to the ventilation duct of the fresh air system to be made in accordance with the specified requirements, it is also necessary to keep the pipeline horizontal and vertical during the pipeline installation process. It should be noted that during the installation of the ventilation pipe, all connections should be firm and reliable, and there should be no loosening, otherwise the fresh air system will produce noise during operation and bring inconvenience to the user.

Because the host of the system is placed in the bathroom ceiling and other places, not in the conventional living area, the bare metal operation noise of the host is between 30 and 50db, and the ceiling will basically reach the range of noise levels that a person can accept, so the noise of the system can not be felt in the living room and bedroom.

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.

There are many problems that need to be paid attention to when installing the fresh air system, the first is that the distance between the outdoor air inlet and the exhaust outlet should not be too close, otherwise the indoor harmful gases will be sucked back as soon as they are sent to the outside; The second is that the pipe from the indoor return air outlet to the fan part should be as short as possible; so as not to affect the air supply effect if the pipeline is too long; The third is that the position of the fan should be placed away from the living and working area, such as the kitchen, bathroom, balcony, etc., so as to avoid the wind noise affecting the rest of the stool when the machine is running and it is known; Fourth, the location of the main engine installation needs to reserve a maintenance port to facilitate the replacement of the filter screen and the maintenance and cleaning of the infiltration brigade.

When installing the fresh air system, you must pay attention to the following issues:

1. The fresh air host must avoid being too close to the bedroom, or the noise pollution really can't accept the rock hunger.

2. Avoid right-angle bends in fresh air pipelines.

3. The air supply and exhaust pipelines should be separated.

4. If you encounter an air conditioner, you should also pay more attention.

5. Try to do the top delivery, side row, rough and early return.

Precautions for installation of ceiling-mounted fresh air system.

1) The fresh air system is generally installed in the form of a suspended ceiling, which will have a certain impact on the floor height, so it should be included in the design and planning before the decoration, and the appropriate fan size should be selected, so that it is convenient for the service provider to design a reasonable installation plan and construction, ensure the quality of the system, and will not destroy the overall decoration pattern in the future.

2) The fan is generally placed in a relatively secondary area such as storage room, cloakroom, etc., so as to avoid the sound of machine operation affecting sleep and rest. It is not suitable for the kitchen and bathroom, although these two areas have suspended ceilings and there is enough space to install fans, but due to the high humidity, the air quality is not very good, in order to reduce the adverse effects on the fans, it is best not to install them in the kitchen and bathroom.

3) The exhaust outlet should be selected in an area where people are more concentrated or stay for a long time; The air intake should be arranged in a position that allows air to flow from the front (or side) of the person to the rear, which is more beneficial to health. It is best to keep the distance between the exhaust and air inlets to ensure that the exchanged air does not mix.

4) If it is installed before the ceiling, it is best to use PVC pipe or galvanized air duct, although the construction is troublesome, but the service life will be longer; If the ceiling is basically installed, you can only choose a composite hose, which is easy to construct and maintain, and the layout is more flexible.

Install a fresh air system.

What kind of requirements are there:

Different from general household appliances, the fresh air system is not a product that is directly plugged in, but requires professional scheme design and installation to make the entire fresh air system give full play to its role. **The planning device of the fresh air system should consider the placement of the pipeline, reduce the loss of air volume as much as possible, and consider the requirements of the ceiling height.

Places where a fresh air system needs to be installed:

Newly renovated house.

Families with small children at home.

The house type is not transparent and the smell is heavy.

A house next to the road or a house with a source of pollution in the vicinity.

Houses with floors that are too high or too low.

Other special places (computer rooms, hotels, shopping malls, office buildings, restaurants, banks, hospitals).

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.

Is this picture you sent installed? This installation method is completely incorrect, it is best to connect a section of soft connection to the pipe connection of the host outdoors to reduce noise, to fix it with sealing professional tape, and it is not right for you to change the diameter to connect directly to the host, at least connect more than 1 meter of straight pipe, if the space is limited, at least connect a section of straight pipe.
