Comparison between central fresh air system and household wall-mounted fresh air system?

Central fresh air, also known as ducted fresh air, is mainly used in engineering, large office space, hotels and villas. When installing the device, each room needs to enter two pipes: air and exhaust. The main engine has high power, high noise and, of course, large air volume. Generally, the mainframe is placed in a remote corner.

Advantages: it can effectively solve the indoor ventilation problem, can be enjoyed in every room, and can filter the dust in the air.

Insufficient, complicated installation, loud noise, inconvenient replacement of filter elements, single function, too high price, unacceptable to ordinary families, ranging from 8000 to 20000, and high power consumption.

Household wall-mounted fresh air is also called wall-mounted fresh air purification system, which is mainly used in families, offices, schools, hotels, villas, real estate commodity buildings, entertainment places and so on.

Advantages: energy saving, environmental protection and low carbon, simple operation, humanized design and intelligent mode, which can effectively filter harmful gases such as dust bacteria, carbon dioxide, nitric oxide, formaldehyde, xylene and odor smoke particles in the air, with low noise, convenient installation and independent operation. Cost-effective, for example, in ancient times, only 2380 fresh air was hung on the wall, even if each room was only 7000, only air could be detected, indoor air quality could be monitored at any time, and the filtration system was easy to replace.

Insufficient, large shopping malls can not achieve integrated operation. During installation, holes need to be punched 1 10 mm, and the effective area of fresh air is small, each unit is 30m2.
