What are the advantages of ductless fresh air systems?

The pipeless fresh air system is commonly known as negative pressure type (or positive pressure type, which is mainly negative pressure type on the market); Pipeline fresh air fresh air system generally refers to the forced inlet and forced exhaust air have the fresh air system (commonly known as the two-way flow fresh air system), these two kinds of fresh air systems have their own characteristics: general; If you have a basement (referring to the house underground), and if you want to ventilate in the basement, then the two-way flow fresh air effect is good and more powerful. But if your home is a normal building.

Similar to a house type with several bedrooms, living rooms and bathrooms, it is a good choice to choose negative pressure.

The fresh air system duct is connected by soft air duct at the tuyere and the connection of the main nozzle, and the hard pipe is arranged as the main pipeline to connect the host to each tuyere.

Most of the hoses are plastic hoses or composite hoses. There are many kinds of hard pipe materials: PVC, metal, FRP, etc., and the most used hard pipe material is PVC.

The fresh air system has only one pipe, and there is no pipe connection between the inlet and exhaust air, and the exhaust air uses a breathing treasure, which is installed on the glass of the bedroom.

There is pollution in decoration materials and homes, the impact of floor heating on pollutant volatilization is not paid attention to when installing floor heating, high-performance doors and windows are replaced but not equipped with fresh air system, and the Yushidu fresh air system is intelligently purified, and the oxygen-rich fresh air is introduced, which can comprehensively purify the air; The integrated design of air distribution can be directly connected to the PE pipe for fresh air, making the installation more concise and the air volume more uniform. In addition, the split fresh air fan has an intelligent operation mechanism for internal and external circulation, which automatically opens the internal circulation when the indoor carbon dioxide concentration reaches the standard, reducing energy consumption and prolonging the life of consumables; When the indoor carbon dioxide exceeds the standard, the internal circulation is turned off to quickly replace the dirty air and create a healthy breathing environment. The product is designed with large air volume and high residual pressure, which can help the construction party overcome more pipe resistance and maintain sufficient air volume at the end during the construction process.

Its advantages and disadvantages will be analyzed in detail.

First, let's take a look at the advantages of ductless smart fresh air systems.

1. Energy conservation and environmental protection.

The ductless intelligent fresh air system does not require additional air ducts, which greatly reduces the consumption of energy and material sources. In addition, it can effectively filter harmful substances in the outdoor air and reduce indoor air pollution, so as to achieve the purpose of green environmental protection.

Second, high comfort.

Traditional ventilation systems need to manually adjust the air outlet and wind speed, which may cause uneven indoor temperature and affect living comfort. The ductless intelligent fresh air system can automatically adjust the wind speed and temperature according to the temperature difference between indoor and outdoor, so that the indoor comfort is always maintained.

Third, the degree of intelligence is high.

The ductless intelligent fresh air system is equipped with advanced sensors and intelligent control systems, which can monitor indoor air quality and temperature in real time, and automatically adjust the fresh air volume and temperature as needed, which greatly improves the convenience of life.

However, despite the many advantages of a ductless smart fresh air system, it also has some significant drawbacks.

First, the initial investment cost is high.

Due to the high design and technical requirements of the ductless intelligent fresh air system, its initial investment cost is relatively high, which may exceed the budget of some consumers.

Second, the maintenance cost may be high.

Although the operation and maintenance of a ductless intelligent fresh air system is relatively simple, there is still a certain cost to replace components such as filters on a regular basis. This can be a burden for some economically disadvantaged families.

To sum up, the pipeless intelligent fresh air system is gradually becoming a new choice for people to improve their living environment by virtue of its advantages of energy saving, environmental protection, high comfort and high degree of intelligence. However, the disadvantages of high initial investment costs and possible high maintenance costs also require serious consideration <>

1. As follows: 1) PAD: The air duct of the secondary fresh air processed by the fresh air processor.

2) Number of large SAD: air supply pipes.

3) FAD : Duct of fresh air (untreated) drawn from outside the street.

4)rad: return air duct.

2. This is the code name of the air duct of different systems, not the name of the material, KED is the kitchen exhaust pipe, FAD is the new air duct, and EAD is the exhaust pipe.

3. The air supply to the house is called the fresh air pipe, and the air that is discharged to the outside of the house is called the exhaust pipe.

4. The fresh air system is an independent air handling system composed of air supply system and exhaust air system, which is divided into two types: piped fresh air system and ductless fresh air system. The pipeline reputation type fresh air system is composed of fresh air fans and pipe fittings, which purify the outdoor air through the fresh air fan and introduce it into the room, and discharge the indoor air through the pipe.

<>1. Fresh air ducts are very common now, but many people are not very familiar with fresh air ducts. Generally speaking, the fresh air system pipe adopts a hard pipe air duct as the main bridge connecting the host to each air outlet, and the hose is used at the junction of the air outlet and the main engine air outlet, so as to give full play to the advantages of soft and hard pipes, extend the service life of the entire fresh air system, and ensure the effect of air supply and exhaust.

2. At present, the domestic Chunshi fresh air system pipes mostly use PVC, plastic hoses, composite hoses, metals, flame retardant foam plexiglass fiber reinforced plastic and other customized pipes.

1. It is inconvenient to install. When installing fresh air, it is necessary to make many vents on the wall, and punching holes in the wall will cause certain damage to the wall, and the fresh air needs to be installed on the roof of the shed, which will also occupy a certain amount of ceiling space, which will reduce the lifting of the house, thereby causing a sense of oppression to the room.

2. There is a noise problem of a row of wheels. Even if the ventilation duct is wound with insulation cotton, it is impossible to avoid the tung cover, the noise is the operation of the machine itself, and the other is the noise of the ventilation, for people who are more sensitive to sound, it will affect the daily life and rest, the above are the shortcomings of installing fresh air, it is recommended to choose according to their actual situation.
