The city breathes an unbearable weight
In addition to industrial exhaust pollution, PM2.5, and automobile exhaust
There are also indoor formaldehyde, total volatile organic compounds
and even bacteria and viruses...
As a result, the demand for air purification is becoming more and more popular
In addition to air purification in the home space
When we enter a public indoor space
I can't help but ask: shopping malls, restaurants, hotels, hospitals
and other crowded places
How well do they do their air purification?
We are in these public indoor spaces
Is the air you breathe healthy?
Relevant air quality codes
The "Indoor Air Quality Standard" (GB/T 18883-2020) issued by the Ministry of Environmental Protection and the Ministry of Health clearly points out the physical, chemical and biological indicators of indoor air quality, and the "Hygienic Code for Centralized Air Conditioning and Ventilation Systems in Public Places" (WS 394-2012) further clarifies that centralized air conditioning systems in public places "should be equipped with air purification and disinfection devices that remove microorganisms, particulate matter and gaseous pollutants in the supply air". The "Hospital Air Purification Management Code" (WS/T 368-2012) also makes clear requirements for the average number of colonies in the air in the hospital environment.
In a variety of modern buildings
If the air-conditioning system is not set up reasonably
Purification and sanitizing equipment
The polluted air will flow with the currents
It causes cross-contamination and endangers the health of indoor personnel
How to achieve efficient air purification in commercial and public buildings?
Honeywell offers a variety of air purification solutions for commercial and public buildings
Using electronic purification technology, it has ultra-low wind resistance and obvious energy-saving advantages
● Low operation and maintenance cost, one-time investment, long-term use
● High purification efficiency, both dust removal and sterilization effects
● For users who are more sensitive to air quality, UV nanotechnology can be superimposed to achieve strong sterilization, deodorization, mildew, anti-fouling and self-cleaning, and air purification functions
Let's take a closer look at Honeywell
