Is it necessary to consider dehumidification when designing a fresh air system in the north?

1.The installation of fresh air dehumidification all-in-one machine in the north is mostly in the basement or basement, the terrain is relatively low, or the environment is relatively humid. This kind of place is cool all year round and there is no sunlight, so even in the dry winter in the north, it is still humid to the point that it is easy to mold, even in winter, let alone summer, so it is natural to need a dehumidifier.

to help dehumidify, perennial drying. In the north, the phenomenon of cold bridges often occurs, because the outdoor weather in the north is relatively cold in winter, and the indoor is in a state of heating for a long time, and the temperature difference between indoor and outdoor is large.

2.Due to the local thermal conductivity at the junction of the inside and outside of the house.

Larger, the heat transfer capacity is enhanced, the local temperature drops sharply, and the hot air in the house is cold to form a water mist adsorbed on the wall, which will lead to the phenomenon of dampness and mildew in the house. In the long run, not only will it become moldy, but it will also cause problems such as water seepage and peeling of the wall. Heating starts in northern cities in winter.

Northerners are inseparable from heating in their daily lives, and it is easy to have a "cold bridge phenomenon" when the room is often heated. The so-called "cold bridge phenomenon" refers to the phenomenon that water mist is adsorbed on the wall at the corner of the exterior wall, at the corner of the interior wall and the exterior wall, and at the overlap angle between the roof and the exterior wall.

3.This is the case of reinforced concrete structures.

The houses mostly occur in columns and beams, and are brick-concrete structures.

Most of the houses occur in the ring beams. After the installation of the fresh air system, it is mainly for indoor ventilation and air purification. Except for a full heat exchange system, there will be no great improvement in the humidity of the indoor air. So the relative humidity of the external environment.

Large, so a dehumidifier was installed. But whether it's a humidifier.

It is also a dehumidifier, which does not conflict with the installation of the fresh air system. And the fresh air system is based on the ventilation function.

4.It also adds a filtration system, a sterilization and disinfection system, a temperature regulation system, etc., to filter and disinfect the air sent into the room before sending it into the room, which not only improves the oxygen content of the room, but also makes the air fresher. Before renovating, it is necessary to decide whether to install a fresh air system and its style.

It is generally recommended to install a ducted fresh air system, which is much more expensive, but the effect is many times stronger. The ductless fresh air system is only suitable for small spaces, and the function is too weak in large spaces.

It is necessary. In this way, it will not make a person's moisture particularly serious, and you can also get a very good experience in life, which can protect the body well and will not make ** peeling.

The weather on the other side is drier than in the south, but it is also necessary to dehumidify when designing a fresh air system at home, because the return of moisture occurs in spring.

In the north, dehumidifiers are installed in basements or basements, which are relatively low-lying or humid environments. This kind of place is cool and does not see sunlight all year round, so even in the dry winter in the north, it is still humid to the extent that it is easy to mold, and naturally needs a dehumidifier to help dehumidify and dry.

There is no need, because the weather in the north is particularly dry, and there is a fresh air system in the whole house, which can circulate the air, and the home will not be particularly wet.

I think it's necessary to think about it. In this way, there will be a good fresh air system. You can also get a very good air quality in your life. There will also be a good air in the house, so it won't feel very dry.

The ordinary dehumidification system has no obvious dehumidification effect in the damp and hot indoor non-ventilated, and the indoor doors and windows are closed when the air conditioner is turned on, which is not suitable for ventilation; Secondly, the independent dehumidifier should be poured water frequently, and the independent dehumidifier will often shut down automatically when the water is full, which is also a dehumidification that ordinary fresh air cannot do.

As buildings become more and more airtight, natural permeation of convection ventilation is impossible. However, the high level of suspended particulate matter in urban air has become the leading evil of urban air pollution. A fresh air dehumidification system is indispensable.

There are fresh air fans that support dehumidification, such as the Honeywell DR90's dehumidification and fresh air purifier, or you can choose a pipeline dehumidifier to be integrated into the fresh air system to achieve dehumidification.

The general fresh air system does not support the dehumidification function.

Say it in 2 steps.

The first is that formaldehyde cannot be removed.

The purification principle of fresh air is to inhale the outdoor air and then purify it. It is fed into the room through various air outlets. The indoor air is then extracted and discharged outside.

He is powerless against the sources of pollution generated in the room. The source of contamination can only be diluted by air circulation. But the effect is not ideal.

It's better to open the window and ventilate directly.

Dehumidification requires a fresh fan equipped with a dehumidification function.

Finally, the penetration rate of fresh air in foreign countries is very high. Like water, electricity and gas, it is the standard configuration of new houses. But his biggest role is to avoid opening windows, prevent dust, and keep indoor air circulation. Ideal for office buildings and basements.

The purification of foreign fresh air is mainly aimed at large particle pollutants such as dust and pollen. To prevent fresh air in China, a special filter is needed, but the life of the filter and the frequency of replacement are amazing.

In my own experience, I don't support the installation of fresh air. The air quality in the country is not suitable for fresh air. Generally, businesses will advertise that the filter of fresh air only needs to be changed once a year (In fact, the person who installs the fresh air basically won't spend money to change it after a year, at least I haven't seen it.

But they don't know that the filter is expired, and that the filter itself is a source of air pollutionBut that's the kind of place in Hainan. If it is Beijing, it is estimated that it will be changed in 2 months. If it's on the road, you can't carry it for 1 month.

When encountering sand and dust, it will be finished directly.

If an anti-filter is installed, the real life of the filter may be calculated in hours. A filter** hundreds to thousands, you can consider for yourself.

OK. The fresh air system helps to dehumidify and prevent mildew, and the purification and ventilation system with full heat exchange function (** type, cabinet type) can effectively adjust the indoor and outdoor temperature and humidity, and actively discharge the indoor dirty and humid air in time to avoid the accumulation of humid air in the room.

OK. The air in the south is relatively humid, and food, clothing, daily necessities, etc. are more likely to become moldy, so dehumidification must be considered; However, at present, the air quality is poor, and the year is not as good as the year, so a new dehumidification fan was born. There are some fresh air brands on the market that have dehumidification functions that far exceed those of dehumidifiers and air conditioners.

Maiwei Animation Co., Ltd. focuses on the principle of high-quality dehumidification fresh air system 3D animation design. Using advanced 3D animation technology, the animation simulates the "intelligent 3 constant system demonstration". The whole animation is divided into three parts, the first part shows the installation link, the second part shows the debugging link, and the third part shows the use link.

No, because the filter element inside the fresh fan is paper, and the dehumidifying air conditioner has this function, and a fan can also be installed to dehumidify.

The fresh air system can only exchange indoor and outdoor air, and the dehumidification effect is not large, so you can buy a dehumidifier.

Hangzhou Laishi Electric's "Aileda" brand, fresh air dehumidifier series is fresh air + dehumidification system, "Aileda" fresh air dehumidification series are:

One-way fresh air + dehumidification series;

Two-way fresh air + dehumidification series;

The equipment is widely used in: villa basements, clubs, office buildings, hotels, conference rooms, chess and card rooms, Internet cafes, KTV, high-end houses, large shopping malls, underground civil air defense projects and other places that require humidity and air quality.

First of all, I don't know why I should consider dehumidification in the north, the fresh air system now has a lot of functions and has a dehumidification function. You need to install it on it, and there is no problem.

This is the function of popularizing the new style: it is a set of devices that can be continuously ventilated. With the new style, you don't need to open the window.

When ventilated, the dust can be filtered and can be in the heat**. It's good to make sure that there are two parts to the new fan, one is the motor and one is the filter. There are many other characteristics in the fresh air system that can be learned more about if the north and south or things do not penetrate the natural ventilation, but accept the new air system, you need to consider developing a habit of opening windows or it is also a home at home.

It is also necessary to consider whether there is a respiratory disease or if the child is affected by formaldehyde. It is also necessary to consider, but I don't know if the air conditioner ventilation function and the new style belong to a new style. The fresh air system also includes a filtration function.

One can also provide many features from people Air conditioning. This is very necessary. Fresh air is mainly solved by the decorative pollution of indoor air, so indoor air indicators are in the value of human safety, increasing the oxygen content of indoor air and reducing the carbon dioxide content in the room.

The new air system is filtered through the outdoor fresh air, the heat exchange is sent to the indoor space, and then the indoor dirty air is discharged from the system.

The function of the fresh air system is air purification sail beard (the purifier can only filter the local air, and can not change the component ratio of the air, many indoor harmful gases can not be filtered) air conditioning (the air conditioner mainly regulates the temperature, it is the internal circulation system. At present, some air conditioning products integrate purification functions, but it cannot replace the single filter water and cannot change the air composition. Therefore, when it comes to respiratory health, a new wind system is a must-have.

If the new air system is a new fan with a "full heat exchange" function, then in the case of indoor humidity and outdoors, it is a certain dehydration effect. Sedan tracks.

Therefore, what functions are required for specific installation, and the specific user needs to be determined.

Of course, it is necessary to consider the pure humidity of the banquet, although the weather in the north is drier, but the dehumidification is also within the range of the quiet, if you do not consider the dehumidification of the transport and closure, if it is wet, it is not good for the house.

There is no need. Because the climate in the north is dry and not humid at all, there is no need to do dehumidification.

It must be considered. In this way, we can get a good living environment, which is very comfortable to live in, and adds a lot of advantages to the home.

There is no need. Because the climate in the north is relatively dry, there is no need for dehumidification.

Basically, there is no need to save for the basement.

When choosing a suitable fresh air system or fresh air dehumidification system, the following factors need to be considered:

1.Needs: Start by identifying your needs for indoor air quality and humidity control.

The fresh air system is mainly used for fresh replenishment of indoor air, which can provide fresh air and remove indoor pollutants. In addition to providing fresh air, the fresh air dehumidification system can also remove excess moisture from the air. Therefore, if you have high requirements for air quality and humidity control, a fresh air dehumidification system may be more suitable.

2.Space requirements and size: Choose the appropriate system capacity based on the size and scale of the space you need to cover. Larger spaces may require larger capacity fans and dehumidification capacity.

3.Setup and Control: Consider how the system is set up and controlled.

Some fresh air systems and fresh air dehumidification systems are equipped with intelligent control functions, which can automatically adjust the operation according to the indoor humidity and temperature. In addition, some systems can be integrated with their own equipment or building automation systems.

4.Energy efficiency and noise: Focus on the energy efficiency level of the system and the noise of its operation. Choose a system with high energy efficiency and low operating noise to achieve energy savings and provide a comfortable indoor environment.

5.Maintenance and Service: Consider the maintenance and service needs of the system. Understand the frequency of maintenance and maintenance costs required for the system, and evaluate the after-sales service support provided by the supplier. The annihilation calendar is good.

Ultimately, based on your specific needs and budget, consider the above factors to choose a fresh air system or fresh air dehumidification system with the right features and performance. It is recommended to consult a professional or business provider before choosing, so as to get more accurate advice and customized prescriptions according to your specific situation.

If the fresh air system is a fresh air fan with the function of "full heat exchange", it has a certain dehumidification effect when the indoor humidity is high and the outdoor is relatively dry.

This is because "total heat exchange" allows both temperature and humidity to be exchanged. However, the effect of dehumidification through humidity exchange is certainly not as good as that of dehumidifiers.

If you want to achieve better dehumidification effect and continuous dehumidification, it is recommended to choose a dehumidifier or a fresh air dehumidification machine.
