With the improvement of living standards and housing conditions, more and more families are installing a set of home fresh air systems when they are renovating to achieve free breathing in their houses. A home fresh air system is a kind of air purifier, it can filter out the harmful substances of the outside air, and deliver healthy and fresh air to the room. Compared with the ordinary ventilation system, the new air system has a stronger ventilation effect and is more energy efficient.
The effect of the new home air system
1. Ventilation
Fresh air system 24 hours a day uninterruptedly for the room to provide fresh filtered outdoor air, discharging indoor carbon dioxide, formaldehyde, and other dirty air, allowing the human body to breathe fresh, pure air at all times. Ordinary ventilation equipment when open when not closed, not only can not be continuously ventilated, and there is no organization of a reasonable pressure field and airflow path, and thus can not achieve the true meaning of air replacement, the effect of ventilation is far worse than the fresh air system.
2. Reduce noise
Modern people live under great pressure and are afraid of noise pollution, they always close the windows at home, but the air can not circulate through the closed doors and windows, which causes micro-deficiency of oxygen and has a bad effect on the body. A fresh air system can introduce fresh oxygen-rich air from the outdoors, the home of dirty air out of the outdoors, without having to open the window to achieve indoor and outdoor air replacement, reducing the outdoor noise in the room. And the home air system can be adjusted according to the user's fresh air needs gear, in the low-speed operation the noise is smaller, the night rest can be adjusted to the first gear, and almost do not feel its existence. But the ordinary ventilation equipment itself is noisy when running, and even more unable to block the outdoor noise, the machine works on the daily life of a greater impact.
3. Prevent air conditioning disease, reduce energy loss
Nowadays, air conditioning has become a summer standard, air conditioning makes people comfortable at the same time also brings air conditioning disease. Long time in an air-conditioned environment, people work and study, due to closed windows and doors, air circulation, the environment can not be improved, there will be nasal congestion, dizziness, and some skin allergies. The new air conditioning system can be in the premise of closed windows and doors to the air-conditioned room to send a steady stream of fresh air after filtration, discharging indoor dirty air, effectively preventing air-conditioning disease, reducing the energy loss caused by the ventilation of open windows.
4. Beautify the living space
It is said that the best home appliances can integrate with the furniture environment, and even complement the home environment, the new air system is so. Installation of home air systems only need to reserve a wall-mounted air conditioner on the outside wall size of the position can be, will not take up too much space, and the appearance of fashionable simplicity and beauty, greatly enhancing the taste of modern homes, is a symbol of modern high-quality life. Ordinary ventilation equipment, wiring more exposed outside and without any design style, will affect the entire residential decoration style.
How to judge the effect of the new home air system
1. Judge the effect of the new home air system in addition to PM2.5
Judge the effect of home air removal PM2.5, on the one hand, we need to use the PM2.5 detector. It should be noted that do not blindly pursue "zero outlets", which is not what we need; do not only check the new air system outlet PM2.5 value, outlet PM2.5 value does not mean that the indoor PM2.5 value is reduced very quickly.
On the other hand, we have to look at the airflow of the new air system. To reduce the indoor PM2.5 value quickly, the new air system needs to have enough air volume, and the new air system with an internal circulation function makes it easier to achieve this.
It is recommended to use a PM2.5 tester to test the PM2.5 value at the air outlet of the new air system, then test the indoor value, and then compare the value obtained with the outdoor PM2.5 value. In this way, you will be able to judge the anti-haze effect of the new air system.
2. Judge the ventilation effect of the new home air conditioning system
Ventilation is the real role of the new air system. Judge the ventilation effect of the new home air conditioning system standard, not the wind speed, but more importantly, the amount of new air (not wind volume.)! (The air volume value of some machines is very much indoor circulating air). How much fresh air the new air system sends in per hour is the most important factor in determining the ventilation effect.
In addition, the effectiveness of fresh air ventilation in the home is measured not by the indoor PM2.5 value, but by the indoor carbon dioxide concentration. If you can test the indoor carbon dioxide concentration, you will find that after sleeping for 8 hours in a closed room, the carbon dioxide concentration in the house has reached an unhealthy value. After switching on the new air conditioner, you pay attention to the indoor carbon dioxide concentration, and if you can keep it within 1000 PPM all the time, then the ventilation is very effective.
3. Judging the effect of formaldehyde removal by home fresh air system
The principle of household fresh air system to remove formaldehyde is not "filtering", not through the machine built-in formaldehyde filtration device, but through the ventilation of indoor polluted air instead of clean fresh air from the outside world. That is to say, indoor formaldehyde will not pass through the filter of the new air system, but through the ventilation of the new air system from the indoor extrusion out to the outside.
Therefore, the formaldehyde removal effect of the new air system depends entirely on its fresh air volume. New air volume is enough, the effect of formaldehyde removal will naturally be very good.
4. Judge the effect of the household fresh air system in addition to the odor
As with carbon dioxide and formaldehyde, the home air conditioning system in addition to the odor also through continuous ventilation will cause indoor odor. However, the new air system must remove harmful gases and odors from the air sent into the room. If the new air system does not have the technology or device to deal with harmful gases, then although it can efficiently filter PM2.5, it can not filter harmful gases, chemical odors, and car exhaust. Therefore, we should pay attention to whether it is equipped with an activated carbon filter as standard when purchasing a new air system. The activated carbon filter should not be too small, or it will fail soon!
5. Judge the household's new air system noise reduction effect
The noise of the new home air system is the index most easily ignored by consumers, and it is the element that most affects the user experience. Therefore, when buying a new home air must pay great attention to the noise index. Take a look at the noise decibel count on the details page and ask the seller for specific data if the information is not complete. There are also guides available online that can make it easier for you to understand the meaning of the noise decibel count of a new air conditioning system.
The comparison of the effect of household fresh air and ordinary ventilation equipment
1. The effect of air exchange
Household fresh air system air volume, the air in and out, airflow organization is scientifically rational and orderly, good air exchange effect. At the same time, the new air system 24 hours a day uninterruptedly for the indoor provision of fresh filtered outdoor air, leaving no dead ends, continuous, allowing the human body to breathe fresh, pure air at all times. The ordinary ventilation equipment when open when not closed, not only can not be continuous ventilation, and there is no organization of a reasonable pressure field and airflow path, and thus can not achieve the true meaning of air replacement, the effect of ventilation is far worse than the fresh air system.
2. Energy saving effect
With the heat recovery function of the total heat exchange fresh air system host to increase the total heat recovery system, in and out of the air through the heat exchanger when the preheating and pre-cooling of the energy exchange, you can retain 70% of the energy of the indoor air, to avoid the loss of energy, reduce the loss of warm and cold air, energy saving effect is good. Ordinary air exchange equipment directly out of the indoor air outside, resulting in the loss of indoor air cold or heat, resulting in a waste of energy, is not conducive to energy saving.
3. Aesthetic effect
Home air system decoration is beautiful, atmospheric, stylish, and has perfect integration in different decorative styles, the host ceiling hidden installation does not take up indoor space, does not affect the overall aesthetics, greatly enhances the taste of modern homes, and is a symbol of modern high-quality life. The ordinary ventilation equipment, hanging glass installation, and more exposed lines are not beautiful, affecting the entire residential decoration style and layout.
4. Silent effect
The home air system is very quiet when running (generally 30 decibels), you can hardly feel its presence, and the host of the new air is generally installed in the bathroom ceiling, which can play a better sound insulation effect. In addition, the new air system does not need to open the window on the line for ventilation, but also to avoid the disturbance of outside noise. However, the ordinary ventilation equipment itself is noisy, but also can not block the outdoor noise, when running on the daily life of a greater impact.
