How does the fresh air system work, what is the working principle of the fresh air system?

1.The main thing is to install a special device in one corner of the confined space to bring fresh air into the room. At the same time, on the other side, the indoor air is exhausted to the outside with special equipment. In this way, a layer of flowing fresh air will be formed in the room to achieve the effect of ventilation.

Second, the main advantages of the fresh air system.

1.If there are no windows in the home, you can breathe natural air without opening the windows, which can effectively achieve ventilation.

2.As long as the home is well ventilated, it can avoid mold and moisture of indoor furniture or clothing, and can also better discharge some harmful gases from the outdoors, which is beneficial to people's health.

3.When the indoor humidity is relatively large, you can also turn on the fresh air system to discharge the indoor moisture out of the outside, which can save heating costs.

4.Not only can the indoor air be discharged from the outdoors, but also some bacteria or germs can be effectively discharged indoors, which can make the indoor air cleaner. At the same time, this system can achieve an ultra-quiet effect, which is very convenient to use and will not affect people's normal rest.

Three. The main function of the fresh air system.

1.It can play a role in ventilation, allowing people to breathe fresh air, exhaust polluted indoor air, and keep indoor air fresh for 24 hours.

2.It can play a role in dust removal and deodorization. If there is a peculiar smell in the home, it is better to open the fresh air system to discharge it, or you can expel some dust and bacteria floating in the air to the outside.

3.It can also have the function of removing moisture. Indoor moisture doesn't just come from the kitchen or bathroom, but the human body also releases moisture. Therefore, after the fresh air system is turned on, it can effectively remove indoor moisture and protect people's health.

4.The fresh air system can also effectively regulate the indoor temperature. In the summer, it can expel hot air from the interior to the outside. In winter, it can also effectively reduce indoor temperature loss and better improve the heating effect.

The use of full heat exchange system for machine ventilation can effectively discharge the turbid air in the room and reduce the damage of mold, ticks and other harmful bacteria and viruses to the human body. At the same time, it can bring fresh air into the room, bringing all-day comfort and warmth to your life.

The fresh air system realizes indoor and outdoor air circulation through exhaust and supply air pipes, and purifies the incoming air at the same time to achieve full heat exchange. The fresh air system is a set of independent air treatment system composed of air supply system and exhaust air system, and its basic principle and function is to introduce outdoor air and discharge indoor turbidity at the same time, so as to achieve the effect of ventilation without opening the window.

When the fresh air system is installed with an electrostatic dust box or filter, it will have the function of air purification. In addition, the fresh air system is equipped with a heat exchanger, which has a heat exchange function.

Advantages and disadvantages of fresh air system

The fresh air system can circulate indoor and outdoor air without opening the window, thus reducing the feeling of suffocation. Although some fresh air systems have the function of purifying the air, in the case of extremely severe air pollution, the filtration capacity of the fresh air system is insufficient, and the air entering the room is still not clean enough.

If the filtration capacity of the fresh air system is strengthened, the amount of air sent into the room may be reduced, and there will be a difference in air pressure between indoor and outdoor, and the outdoor polluted air will enter the room through the gaps in doors and windows.

The above content refers to Popular Science China - Are fresh air systems and air purifiers the same thing?

The working principle of the fresh air system is as follows: the fresh air system circulates the indoor air through pressurization technology, on the one hand, the indoor dirty air is discharged outdoor, and on the other hand, the outdoor fresh air is sterilized, disinfected, filtered and other measures before being input into the room, so that the room is fresh and clean air all the time. The details can be seen in the figure below.

Turn left|Turn right.

Take the Yunjing fresh air system, which is more popular during this time, for the first time, the turbocharged engine technology of the car is used for fresh air purification, and the air that is about to be discharged is recycled back into the room through heat ** and purification, which not only increases the circulation of indoor air, but also increases indoor pressure, forming a micro-positive pressure environment to prevent pollutants from invading through the gaps in doors and windows.

Relatively speaking, turbo technology is a relatively strong point in innovation, using hot and cold dual channels, supporting dual channel purification, single channel purification, dual channel purification fresh air three operating modes, which perfectly solves the problem of "one-way flow inlet air cooling two-way flow air volume" of traditional technology.

In terms of filtration, mainly according to the different indoor and outdoor pollutants, the dual-channel filtration of fresh air channel and purification channel is used for targeted optimization, and through 5-6 stage tower filtration, the removal rate is 99%, and the removal rate of sulfur dioxide (soot odor) is 95%. The fresh air volume reaches 300 cubic meters per hour, and the purification capacity reaches 600 cubic meters per hour. The photocatalyst reaction formed by its 254nm wavelength ultraviolet rays sterilizes and degrades the activated carbon garbage bin, which avoids the secondary pollution caused by the traditional activated carbon adsorption method that cannot really kill bacteria and viruses and degrade formaldehyde and other decoration pollution, excessive adsorption or bacterial breeding after moisture absorption.

Since the 254nm wavelength ultraviolet light is standard for sterilization in hospitals, it has a strong sterilization ability to ensure that no ozone is generated.

For home use, the so-called ** fresh air system basically refers to the use of a "full heat exchanger" for continuous ventilation of indoor air.

**Three types of fresh air systems.

1. One-way flow fresh air system:

The one-way flow fresh air system is the "forced exhaust, natural air intake" system, its working principle is to rely on the suction generated by the main engine to form indoor negative pressure, and send the dirty air to the outside through the air supply pipe, in order to balance the indoor negative pressure, the relatively fresh air outside the room enters the room from the pre-installed air intake hole, so as to achieve the purpose of ventilation. The one-way flow fresh air system is naturally carried out when the air is entered, and the system has few installation pipes and simple installation, and is generally used in residences, apartments or office spaces with high building heights.

2. Full heat exchange fresh air system:

The full heat exchange fresh air system is an upgrade of the two-way flow fresh air system, the main engine has added a full heat system, the incoming and outgoing air is placed in the heat exchanger in the host, and the energy exchange of preheating and precooling is carried out, which can retain 70% of the energy of the indoor air, and the use of air conditioning is very energy-saving, even if the temperature difference is large, it will not affect the indoor temperature. The full heat exchange fresh air system is suitable for apartments, villas and office spaces with an area of less than 1000 square meters, with high fresh air quality, high efficiency and energy saving.

3. Two-way flow fresh air system:

The two-way flow ** fresh air system is a kind of forced exhaust and forced air supply system, which is mainly composed of a group of forced air supply system and a group of forced exhaust system. The difference with one-way flow is that the form of air supply is changed from natural wind to forced air supply, fresh air enters the room from the pipe of the air supply system, and the exhaust air is discharged to the outside through the pipe of the exhaust system. The two-way flow fresh air system can filter the introduced fresh air, the fresh air quality is good, the ventilation effect is more thorough, and it can be installed and used in both home and public places.

How does the fresh air system work? Is it effective?

The fresh air system is equivalent to a ventilation fan + filter. One intake draws dirty air into the filter, and the other exhausts fresh air. This is how the fresh air system works.

In the room, it is necessary to go through the pipes to form a number of air inlets and exhaust outlets, which are concentrated in the fresh air host. It's called a system.

It is the new fan that pumps the outdoor air in, filters and purifies it at all levels, and sends it indoors, and at the same time can output the harmful gases in the room to the outside through the pipeline, so as to replace the fresher air without opening the window. Fresh air fan.

The fresh air system is a circulating ventilation system composed of fresh air host, air duct, tuyere, electrical control, etc., referred to as fresh air. The fan in the fresh air host provides power for air circulation; Fresh outdoor air is filtered and purified and then introduced into the room through air ducts and tuyeres, and sent to all the places needed in the room. The indoor polluted air is discharged to the outside through the tuyere and air duct, so that the effective circulation of indoor and outdoor air is completed through the fresh air system to ensure that the indoor air is fresh and comfortable. When the outdoor haze is more serious, and other particulate matter will enter the room through doors and windows, which poses a threat to human health, the fresh air system can ensure that indoor particulate matter meets the health standard through effective filtration and purification.

The fresh air system is an independent air handling system for fresh air.

It is mainly composed of air supply system and exhaust system, the air outside the fan is filtered through the filter screen and sent to the room, and the indoor air is discharged outside through the bright fan or air negative pressure, so that you can breathe fresh air outside without opening the window.

It can not only avoid the disadvantages of opening windows, but also have the benefits of opening windows.

Carbon reduction and oxygen enrichment. It can reduce indoor carbon dioxide and increase indoor oxygen content, and sufficient oxygen can increase the body's metabolism and improve people's immunity.

Dust removal and anti-bacterial. It is to filter the outdoor air and then send it indoors, which can prevent dust and germs from entering the room to a certain extent, and reduce the dust accumulation in the room.

Reduce the impact of noise.

Nowadays, the urban living environment is sometimes inevitably outside noise, and the damage to the object without opening the window reduces the noise to a certain extent, which affects our daily life, and the fresh air system can help you breathe the fresh air outside without opening the window.

Equalize the humidity in the air.

The air circulation back and forth can keep the room at a good humidity without being too dry or too wet, and the items in the room are not easy to breed mold.

Reduction of harmful gases in the air.

We all know that the cheap and effective way to remove formaldehyde is to open the window for ventilation, but sometimes the window is not wanted to be opened due to external forces, and the fresh air system can maintain 24-hour ventilation, which is more conducive to the discharge of harmful gases outdoors.

Does not affect the indoor temperature.

In addition, with the fresh air of the full heat exchange system, there is no need to worry about the indoor air affected by the change of seasonal temperature, the full heat exchange system will ** the temperature of the indoor air, balance the temperature of the outdoor air, and achieve the air temperature entering the room is not cold in winter and hot in summer, and does not affect the use of other household appliances.
