What is a ductless fresh air conditioner? What are the advantages and disadvantages of ductless fres

The pipeless fresh air system means that there is no need to lay pipes like the traditional fresh air system, the machine is directly wall-mounted or floor-mounted, connected to the outdoor pipeline, and the filtered fresh air is transported to all corners of the room through the micro-positive pressure technology, without dead ends, effectively removing formaldehyde, removing and removing ozone, and effectively purifying the air.

The advantages of ductless fresh air systems are:

There is no need to lay pipes like the traditional fresh air system, and it can be installed even after decoration, which is more convenient to use;

Easy to install, only need to punch holes to connect with the outdoor or directly replace the perforated glass, and the installation can be completed in one or two hours;

To prevent secondary pollution, the traditional fresh air system pipeline is relatively closed, which is easy to cause dust to remain, which will breed a large number of bacteria and endanger human health.

The ductless fresh air system is currently the best system on the market that can really achieve air purification, the disadvantage is that it should be a little more expensive, its filter element needs to be replaced for about 3 months to 6 months, so the cost is higher, but compared to human health, this is not expensive.

"No duct" fresh air device refers to compact fresh air equipment, generally wall-mounted fresh air device. Before the appearance of wall-mounted fresh air devices on the market, all fresh air equipment involved air ducts. **Fresh air fans send air into every room of the house through these ducts, which are usually located at the top and hidden by the ceiling.

The wall-mounted fresh air converter does not need ducts, it is hung directly on the wall and inhales outside air through the holes in the wall. Its installation consists only of punching holes in the wall and hanging the device. The filtration system of modern wall-mounted fresh air is generally in place, and the market is not high.

A wall-mounted fresh air diffuser of an imported brand can be bought for more than 3,000 yuan, and a single fresh air dishman can meet the fresh air needs of a small house. Some examples of ductless fresh air vents: Di'an, Panasonic, Ayerspie, etc.

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.

At present, each has its own advantages, but ductless fresh air is the future trend. In particular, the application of Internet of Things technology has made the pipeless fresh air more advanced, for example, Haoting pipeless intelligent fresh air is very popular now. To summarize a few points:

1. Install the pipeline fresh air before decoration, and it can also be installed after the decoration without pipeline fresh air; 2. No pipeline, no fresh air, no pipeline, to avoid secondary pollution; 3. The pipeline fresh air is more mature, suitable for super-large areas, but the cost is high, and the pipeless is more suitable for family use, and the installation and use are more convenient.

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);

The pipeline fresh air and fresh air system generally refers to the fresh air system (commonly known as the two-way flow fresh air system) that is equipped with forced inlet air and forced exhaust

Each of these two fresh air systems has its own characteristics: general conditions; 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.

Indoor and outdoor air quality problems have attracted more and more attention. It is everyone's dream to have a healthy home life, but indoor and outdoor air quality is polluted, such as formaldehyde, haze, car exhaust, etc., which affects people's healthy life.

Because the wall-mounted fresh air system does not require ducts and can be installed directly, it is very convenient, so it is favored by more and more home users. But how many people will know what its advantages are? A brief summary for everyone!

The advantages of the wall-mounted fresh air system are:

Relatively low. The wall-mounted fresh air system is relatively low, generally around 3000-6000 yuan.

The fuselage is small and does not affect the decoration. The wall-mounted fresh air system is generally small, does not occupy too small an area, and can be integrated with the decoration style.

The installation is simple and convenient, and the renovated house can also be installed. The wall-mounted fresh air system only needs to open one vent and can be easily installed and used.

It is easy to maintain in the later stage. The case is easy to disassemble and the filter can be easily replaced.

Fresh air equipment: to ensure that the indoor oxygen content reaches a healthy level, and at the same time, the introduced air is highly purified, and the harmful substances (formaldehyde, benzene, etc.) that are difficult to purify are taken away from the room. This is a mature solution in developed countries in Europe and the United States, whether it is commercial or residential for decades.

The air volume of the fresh air must be high, preferably a fresh fan with full heat exchange function to reduce the loss of indoor heat and cold capacity.

Air purifier: It can only circulate and purify indoor air, which can purify smoke, particulate matter, dust, etc. in indoor air. However, the room must be sealed, and we all know that the carbon dioxide exhaled by the human body and the indoor suspended formaldehyde cannot be purified by the purifier, so the air purifier can only solve the indoor air for a short time, and cannot completely improve the air quality of our living space.

The fresh air dream fresh fan can ensure the freshness of indoor air 24 hours a day without opening the window, ensure the continuous exchange of indoor and outdoor air, and fully ensure the oxygen content of indoor air. The pollutants in the air are continuously discharged from the outdoors, which fundamentally solves the problems of decoration pollution, geothermal floating ash, indoor hypoxia, and VOC emissions from the human body. Mainly used in homes, offices, schools, hospitals, hotels, etc.

It is also a necessity for the rooms of the elderly, children, and pregnant women!

Supplement: For the fresh fan, the problem of unsealed room is not a serious problem - the fresh fan generally injects more air than the extraction, which generates positive pressure, so that the indoor clean air is slowly squeezed out through the door crack, and the outdoor unfiltered air is inhaled through the door crack to ensure the indoor cleanliness.

Hope to adopt.

To put it simply, ductless fresh air is suitable for household use, and ducted fresh air system is suitable for use in large places, when we buy products, we must first understand its working principle, including our common household appliances, otherwise those things that seem to help us will harm our health.

For example, there are some fresh air systems, the air inlet and the air outlet are close to each other, according to its working principle, it will cause this situation, the fresh air that has just been purified is quickly discharged, and the bedroom and living room far away are difficult to achieve the purification effect.

I recommend the products of Haoting fresh air system, it is divided into two parts, the main engine and the breathing treasure, the working principle is that the host installed in the living room or balcony is responsible for the outdoor air purification and introduction into the room, and at the same time, the breathing treasure installed on the bedroom window is responsible for the indoor dirty air discharge, so that due to the existence of air pressure difference, the indoor will form a fresh air flow from the living room to the direction of the bedroom, so as to achieve the overall purification effect.
