Which is better, fresh air or air purifier?
The function of fresh air system and air purifier is to purify the air.
There are many principles and technologies for air purifier to remove indoor pollutants such as formaldehyde, mainly including: negative ion purification, plasma purification, (activated carbon) filtration purification, photocatalyst purification, and compound purification mixed with various filtration technologies.
However, the National Indoor and Indoor Environment and Environmental Protection Product Quality Supervision and Inspection Center released the main performance evaluation of the air purifier. The results show that the technology of air purifier to purify PM2.5 in the air is relatively mature, but the function and effect of removing formaldehyde are not ideal.
The air purifier deals with inhaling indoor air for purification, and then discharging it indoors, which means that the same air is always stirred. However, if the air purifier is used for a long time, the freshness of indoor air, that is, the oxygen content, will be insufficient, which will easily cause secondary pollution. It can be used in a small area, such as within ten square meters, so it is certain that it is better to use the air purifier directly. If all rooms have fresh air, it is recommended to choose fresh air system.
Fresh air system has a wide range of applications: schools, hospitals, office buildings, bars, KIV or residential buildings, as well as family fresh air systems (suites, villas).
Fresh air system is a new type of air handling system which integrates air supply and exhaust functions. Can discharge indoor dirty air, formaldehyde, smoke smell, odor and so on. Through continuous ventilation and fresh air replacement, and purifying outdoor air through multi-layer progressive filter screen, outdoor polluted air, dust, harmful gases PM2.5, PM0.3 and noise pollution can be effectively isolated, and clean fresh air can be continuously delivered to the room.
Installing a fresh air system is equivalent to installing a green "lung" for the house. It can be ventilated without opening the window for 24 hours, and continuously and forcefully discharge toxic gases such as indoor formaldehyde, benzene, ammonia and other decoration volatiles to protect human health.
1, dust removal function: the dust floating in the air contains many bacteria invisible to the naked eye, so it is necessary to drive away the dust indoors and in the workplace and create a comfortable environment.
2. Dehumidification function: The moisture in the living room comes not only from the bathroom, but also from the human body and gas appliance. Moreover, the current buildings are more airtight, and it is easy to cause the problems that the greenhouse is moldy due to condensation and the beds and walls rot. The fresh air system can remove indoor moisture and keep the living environment comfortable and healthy. Especially in the rainy season in the south, don't worry about clothes drying.
3. Adjust the room temperature: At present, the fresh air system on the market takes the total heat recovery heat exchanger as the mainstream. In summer night, the indoor heat is driven away by ventilation fans, and the outdoor cold air is replaced. In winter, total heat exchange is carried out to reduce the indoor temperature loss and improve the heating effect in winter. Kidman Kidman total heat recovery core, efficient heat recovery, temperature and humidity double recovery, balance indoor and outdoor temperature and humidity difference, effectively reduce the energy consumption of air conditioning floor heating, comfortable and energy-saving.
Now everyone knows which is better, the air purifier or the new fan, in addition to formaldehyde. In the high season of formaldehyde pollution in winter, we must pay attention to the control of formaldehyde. Install fresh air system to effectively remove indoor formaldehyde and create a healthy and safe breathing environment for yourself and your family.
