New air system can not only be used to control haze and filter outdoor air, for purifying indoor decoration pollution and enhance the comfort of the living environment, can also play a great help.
But many renovation users in the purchase of new air system appeared some misunderstandings, that is, too much attention to the brand of the new air host, power and filtration level, but indifferent to other new air materials.
It is important to know that the new air belongs to a ventilation system, since it is a system, it must require a variety of equipment, materials, with the corresponding conditions to use, complement each other in order to play the system's maximum effect.
Because the new air system needs to use a lot of materials, I will summarize it as 3 parts: host, air distribution, piping", a standard, effective and complete new air system must be less than these three parts.
One, the host of the new wind
The host is the core of the new wind system, the market now exists in a large number of new wind host brand: Japan, Germany, the United States, France and China abound in the enterprise, but trace the root cause of the decision of a host of good and bad factors are no more than the following 3 points.
1. Motor
2. Heat exchanger
3. Filtration
Motor? To provide power for the new wind, so the fan is good or bad to determine the new wind host air volume, noise level and the degree of energy consumption. How the three balanced and optimized to reflect the host manufacturer's technical differences, we consult the manufacturer to compare can be.
Heat exchanger? Now the market heat exchanger basically belongs to the full heat exchange (both temperature and humidity exchange, but the conversion has loss). Fresh air host in the state of full heat exchange can reach more than 70% of the heat transfer rate are more excellent products.
Filtration method? Currently there are two mainstream: pure physical filtration (relying on the filter level of the cartridge) and electrostatic dust collection filtration (relying on the electric field generated by the adsorption of particles), the two types of filtration have their own advantages and disadvantages, the host manufacturer to choose the filtration method is also different.
HEPA's filter cartridge is able to filter PM2.5 particles, but due to the relatively small gaps between the fibers, it will be clogged soon after use, and will need to be cleaned and replaced in 2-3 months' time. Electrostatic dust-collecting filtration has the potential to produce ozone, and there is debate as to whether it really doesn't need to be cleaned.
Two, new air (wind)
Some decoration users may be more strange, the new air system is not a host plus a few new air ducts can be dealt with things, how more "wind" equipment?
This actually goes back to the history of the modern air system, the earliest "new air" is actually just ventilation. From the point of view of its function, the simplest exhaust fan can also be regarded as a ventilation device.
But with the new wind technology and modern living environment changes, from one-way flow to two-way flow, from the ventilation needs to filtering and purification needs, and slowly formed the pattern of modern new wind. This new air distribution equipment, that is, air distribution static pressure box.
The main role of the split-air static pressure box has three points:
1. "Static pressure box" as the name suggests, can be part of the flow into the cavity of the dynamic pressure into the static pressure (static pressure determines how far the wind can blow the pipeline), to ensure that the end of the air outlet to meet the expected results.
2. Through the air distribution static pressure box will be the host over the balanced distribution of wind to each room to avoid some rooms too much wind production noise, but also to avoid some rooms get too little wind, no effect.
3. When the wind from the fresh air host passes through the air distribution box, the wind speed will be slowed down, and the sound produced by the wind speed will be reduced. And wind distribution static pressure box lined with a layer of sound-absorbing materials, can reduce the noise generated by the new wind system 5-10 decibels.
Three, the new air (piping)
The piping of the new air is simple enough? From the mouth of the new air host to rip a few pipes to each room is complete? No, there's actually a lot to learn here.
Decorated homeowners for the above two pipe material more or less will have a certain understanding. PPR is the water supply pipe, because it involves the family drinking water source, so the selection of PPR material itself has the basis of health and environmental protection.
PVC material is very common in the decoration, such as PVC wire pipe, wire box, cup comb and cable. However, PVC material is not environmentally friendly enough, the material aging decomposition process will release hydrogen chloride gas, in serious cases will be harmful to human health, therefore, PVC products are generally used in life is not in close contact with the place.
Now, if you let the PVC and PPR used in the place of the swap, are you willing?
I think most people would not be willing to use PVC piping as the family's drinking water piping, which is to take the family's health. But why is it that people let PVC go when it comes to fresh air ducts that deliver clean air indoors?
Above: PVC piping installation of the new air system
Here we do not talk about the installation process of the new air, from the material itself, environmental protection should be the most basic requirements of the ventilation pipe.
The new air system should provide fresh air for the room, but because of the problem of the pipeline and contaminate the air delivered, is not this an extremely lose-lose thing?
However, the current new air market, PVC drainage pipe as a new air ventilation pipe is a common thing, most of the new air users do not know that there is an environmentally friendly ventilation pipe dedicated to the new air - HDPE double-wall corrugated pipe exists.
Placing aside the installation level and noise reduction level advantages, HDPE double wall corrugated pipe in the raw material (PE) has a high degree of environmental protection. PE raw material itself is only C and H atomic structure, colorless, tasteless and non-toxic.
PE materials are used very closely in daily life, for example, fruits and vegetables PE cling film, packaging of food, heating pipes and so on. In terms of environmental friendliness, DHPE pipe is a kind of ventilation pipe which is very suitable for fresh air system.
There is nothing wrong with PVC material as water supply and drainage pipes, but the characteristics of the material determine its applicability and limitations. Orange is born in Huainan is orange, born in Huabei is Hovenia, "cure all diseases" of the pipe is impossible to exist.
If you really want to install a set of "good effect, and environmental protection" of the new air system, in the purchase, please be sure to pay attention to these three parts. Otherwise, your new air system installed, the effect may not be as good as the bathroom exhaust fan.
