How to choose the fresh air system, wall mounted fresh air or ducted fresh air is better?

Installation:

The installation of the piped fresh air system is large, which needs to be carried out simultaneously with the house decoration, and the installation of the wall has not been treated and the ceiling has not been completed. The main machine and the pipeline are hidden and installed in the ceiling, and when doing water and electricity, it is necessary to contact the engineer to check the installation environment, communicate the pipe layout plan, and the installation location of the equipment.

The wall-mounted fresh air system does not need to lay pipes, and can be installed before and after decoration without destroying the original decoration style. It is easy to install, just punch a vent and a few screw holes in the exterior wall to complete the installation. The wall-mounted fresh air is more flexible and can meet the needs of any type of householder, and it is also suitable for small apartment users.

Purification: Due to the large air volume of the main engine and the large air supply area, the ceiling-type fresh air can realize the ventilation of the whole house, and the overall ventilation effect is good. The air supply outlet and exhaust outlet are installed in different positions of the same room, and the fresh air is sent to each room through the pipe, and the dirty air is installed in the exhaust outlet of each room to be pumped out, so that convection can be formed in each relatively independent space, which effectively ensures the quality of the air.

The wall-mounted fresh air system is restricted by the air volume and installation location, and the air supply and purification area is limited, which can meet the purification needs of independent space.

Far dust wall-mounted and ceiling-mounted fresh air systemThe difference is: the wall-mounted type is not subject to decoration restrictions and can be installed at any time, but the ceiling type must be done before decoration; Although the ceiling type is higher than the wall-mounted type, the ceiling type has a larger air supply range and can achieve ventilation of the whole house.

The ceiling-type fresh air system can solve the fresh air ventilation of the whole house at one time, and the air in the whole house can be kept fresh and natural at all times. Whereas.

The wall-mounted fresh air system is more suitable for air purification in a single room, that is, you install a fresh air fan in which room you are mainly active in, so that it is more energy-saving to use. Each has its own good, I want to know more about the Aylespie.

The first is the air volume. **The air volume of the fresh air system is very large, which can fully meet the needs of the whole house. The air volume of the wall-mounted machine is relatively small, and the air volume is suitable for the overall space of 3 to 40 square meters and less than 3 people.

The second is the installation method. **The installation of the fresh air system is hidden, and a lot of pipes need to be laid, and the equipment host and pipes need to be hidden. It looks relatively beautiful and is suitable for installation and use before decoration.

A wall-mounted fresh fan only needs to make a hole in the wall or window to bring in fresh air. It is particularly convenient and quick to install and use, and is suitable for installation and use after interior decoration.

The third is how much land is occupied. **Fresh air will take up a lot of space and area, this is because the pipes are also arranged. The wall-mounted machine does not occupy an area and does not arrange pipes. Generally speaking, the machine itself is not large, and it is all hung on the wall to pick up codes.

Fourth, heat exchange. **The heat exchange efficiency of the fresh air system is relatively high, while the wall-mounted equipment is small in size. The wind and area are directly related to the spring acacia.

Considering that the so-called full heat exchanger has a small fuselage and air volume, the actual effect is not ideal according to the user's feedback. Therefore, the wall-mounted machine does not require heat exchange, and the first consideration is the lightness of the size and the comfort of the customer experience. If you are afraid that cold air will directly enter the room in winter, you can consider using a wall-mounted fresh air system with intelligent electric auxiliary heating to prevent outdoor fresh air from interfering with the cooling of the room.

**Fresh air, also known as pipeline fresh air, is mainly used in engineering, large office spaces, hotel villas. When the device is installed, each room needs to enter the air and exhaust two pipes. The main engine has high power, noise, and of course, the air volume is also large, and the main engine is generally placed in a remote corner.

Advantages, can effectively solve the problem of indoor ventilation can be enjoyed in every room, can filter the dust in the air, insufficient, the installation is more complicated, the noise is large, the filter element is inconvenient to replace, the function is single, the price is too high, the general family needs 8000-20000 can not accept, and the power consumption is large.

Household wall-mounted fresh air, also known as wall-mounted fresh air purification system, is mainly used in homes, offices, schools, hotels, villas, real estate commodity buildings, entertainment venues, etc.

Advantages, energy saving, environmental protection and low carbon, simple operation, humanized design, intelligent mode, can efficiently filter dust bacteria in the air, carbon dioxide nitric oxide, formaldehyde, benzene xylene, odor smoke particles and other harmful gases have low noise, easy installation, independent operation. Cost-effective, such as Gu Nai wall-mounted fresh air is only 2380 per unit, even if one per room is only more than 7000, but only air detection, monitoring indoor air quality at any time, the filtration system is easy to replace, insufficient, large shopping malls can not achieve integrated operation, installation needs to punch 110 mm, the effective area of fresh air is small 30 square meters per unit.

**Fresh air system: complex installation, loud noise, need to lay pipes on the roof, it is difficult to maintain in the later stage, a lot of dust accumulates in the pipes, it is not easy to clean, breed various bacteria, and it is expensive and not suitable for families.

Aodeo fresh air system is a stand-alone wall-mounted, 15 cm ultra-thin design, the use of Aodeo fresh air system to become the world's thinnest fresh air overclocking, does not occupy indoor area, ultra-simple appearance design, full of fashion, so that the living room space in the living fresh air at the same time, but also add a sense of art to the room.

Aodeo Fresh Air provides fresh, clean air indoors 24 hours a day. Discharge the toxic and harmful gases released indoors due to decoration, and introduce outdoor air at the same time, which should be purified, sterilized and dusted.

Wall-mounted fresh air system and ** fresh air system are two common household fresh air systems, and they have some key differences in design, installation methods, coverage, etc.:

Wall-mounted fresh air system.

1.Installation: A wall-mounted fresh air system is usually installed on a wall, similar to an air conditioner. The installation is relatively simple and suitable for homes that have already been renovated.

2.Coverage: Typically only a single room or localized area can be served.

3.Cost: Compared with the best fresh air system, the cost of wall-mounted fresh air system is lower.

4.Noise: Since the device is installed directly in the room, it can be relatively noisy when operating.

5.Maintenance: Wall-mounted fresh air systems are generally easier to access and maintain.

6.Filtration effect: Although it has a filtration function, it may not be as powerful as the ** fresh air system.

**Fresh air system.

1.Installation: The equipment and pipes of the fresh air system are usually installed in the ceiling or inside the wall, which requires professional installation, and it is best to carry out it during the construction of the house or large-scale renovation.

2.Coverage: Able to cover the entire house, providing fresh air to every room.

3.Cost: The installation and maintenance cost is higher than that of wall-mounted fresh air systems.

4.Noise: Since the main unit and pipes are generally installed in isolated locations, the noise level is low during operation.

5.Maintenance: Routine maintenance may be difficult due to pipes installed in hard-to-reach places.

6.Filtration effectiveness: Usually equipped with more advanced filtration systems, which can remove pollutants from the air more effectively.

In summary, the wall-mounted fresh air system is suitable for houses that have been renovated, with low cost, simple installation and maintenance, but limited coverage; The ** fresh air system is suitable for new construction or large-scale renovation of houses, although the cost is higher, but it can provide a more comprehensive and efficient air purification effect. Depending on your living environment, needs and budget, you can choose the type of fresh air system that best suits you.

The brand of wall-mounted fresh air system, now there are a lot on the market, if you want to buy a reliable wall-mounted fresh air system, you need to look at the quality of the machine, air volume, noise, purification level, etc., the air volume of the wall-mounted fresh air system is from 80m h -240m h, ** is also in more than 3,000-9,000 have, mainly in the performance configuration is different. Schmaibo wall-mounted fresh air system suggests that if the local air quality is poor, the fresh air system is better than the air purifier. In addition, when choosing a wall-mounted fresh air system, you should also pay attention to whether the machine has a full heat exchange core, which is the tube to balance indoor and outdoor temperature and humidity.

In the northern region, it is best to choose such a full-heat wall-mounted fresh air system.

When people realized the necessity of fresh air system, various brands continued to innovate in product development and production. More liquid starter models meet people's requirements for fresh air systems. Among them, the wall-mounted fresh air system has been recognized by consumers because of its easy installation.

Below, I will give you a detailed introduction to the use and limitations of the wall-mounted fresh air system

Wall-mounted fresh air is a kind of household ventilation equipment, the equipment is hung on the indoor wall, the equipment is at least equipped with a power fan, filter, and some are also equipped with a heat exchange device, through the ventilation duct connected with the outside, the outdoor air, after filtration and other pretreatment, is sent into the room quantitatively, so as to improve the air quality in a single room. Wall-mounted fresh air fan, according to the different structures, is divided into two categories: unidirectional flow type and two-way flow type, unidirectional flow is subdivided into negative pressure type, air supply type, air supply plus internal circulation three kinds, two-way flow is also divided into full heat type, ceramic heat storage type, sensible heat type.

1.Dilute indoor air pollution. Introduce outdoor fresh air into the room, discharge indoor dirty air, and reduce the carbon dioxide concentration produced by personnel breathing.

There is no better way than to ventilate more," said Song Guangsheng, an authority on indoor environmental pollution detection and control in China. Fresh air is the most effective way to improve indoor air quality.

2.Improve indoor air quality on hazy days. When outdoor fresh air is introduced into the room, the wall-mounted fresh air fan effectively filters the fresh air, so that the indoor air quality is improved by means of ventilation replacement, and the respiratory health of the living room personnel is protected.

1.Wall-mounted fresh air fan can not completely replace the air purifier, at this stage of the domestic civil building door and window airtightness, in accordance with the national standard GB T7107-2002 "building exterior window air permeability performance classification and testing methods" provisions, 10PA wind pressure under the level 2 index of the air leakage volume, which means that in the case of a large temperature difference between indoor and outdoor in winter, the outdoor dirty air that penetrates into the room through doors and windows can reach dozens of cubic meters, and the actual part of the house does not reach this air tightness index. This means that even if a wall-mounted fresh air fan is installed, the fresh air cannot be filtered into the doors and windows when the air tightness of the doors and windows is not perfect.

However, due to the limitation of noise and heat exchange capacity, it is difficult to achieve the CADR value of three to five hundred for the air purifier due to the limitation of noise and heat exchange capacity.

2.The wall-mounted fresh fan, due to the limitation of the equipment structure, the indoor air outlet and return air outlet are generally integrated on the same body, and the distance is closer. The design generally uses a directional, 2 3m s air outlet, and some product air outlets are designed to form an attached jet along the top and wall, so the jet diffusion is better, and the theoretical isothermal air supply radius can reach 10 meters.

However, if there is a partition blocking space, the air flow will be blocked and the air supply effect will be affected.

The difference between a wall-mounted fresh air system and a ** fresh air system is:

The first is the fresh air volume. **The fresh air system has a large fresh air volume, which can meet the needs of the whole house, and the fresh air volume of the wall-mounted machine is relatively small, and the air volume is suitable for an indoor space of three to forty square meters and about three people.

The second is the installation method. **The fresh air system is installed and hidden, and a lot of pipes must be laid, and the host and pipes must be hidden. It looks more beautiful and is suitable for installation before decoration.

The wall-mounted ventilation system only needs to make a hole in the wall or window to introduce fresh air, which is very easy to install and suitable for installation after decoration.

The third is the size of the space. **Fresh air will take up a lot of space and space because it needs to be routed. The wall-mounted machine does not take up space, there is no pipe, and the machine itself is generally not large, and it is hung on the wall.

The fourth is heat exchange. The heat exchange efficiency of fresh air is relatively high, while the wall-mounted machine is small in size, and the full heat exchange is more suitable for application in the host of the larger fresh air system, because the efficiency of full heat exchange is directly related to the wind speed and area. In the case of a small body and air volume, the so-called full heat exchanger is used, according to customer feedback, the effect is not ideal.

Therefore, the wall-mounted machine does not need to pursue heat exchange, and the first consideration is the compact size and the comfort of the user experience. If you are worried about the cold air entering the room directly in winter, you can choose a wall-mounted fresh air system with intelligent electric auxiliary heating to avoid the impact of outdoor fresh air on indoor cooling.
