Comprehensive list of suitable locations for fresh air handling units

A fresh air handling unit is a ventilation device that can exchange indoor and outdoor air, filter and purify it, and regulate temperature and humidity. Its core function is to introduce fresh air into enclosed spaces and expel stale air, improving indoor air quality and resolving issues such as stuffiness, formaldehyde accumulation, and excessive carbon dioxide levels. Depending on the equipment's power, purification level, fresh air volume, and functions, it is widely adaptable to various types of venues, including commercial, office, public service, industrial, and residential spaces. Specific applicable scenarios and reasons for suitability are as follows:

I. Commercial office space

These types of places are densely populated, highly enclosed, and have a large flow of people. Long-term closure can lead to a surge in carbon dioxide concentration, turbid air, and strong odors. They are the core application scenarios for fresh air units, and commercial fresh air units with large air volume and high-efficiency purification are often selected.

• Office buildings and commercial office buildings : Office workers sit in enclosed rooms for long periods of time. Computers, printers and other equipment generate heat and produce trace amounts of harmful gases. Fresh air systems can continuously replace the air, preventing employees from feeling dizzy, drowsy and reduced work efficiency. They are suitable for building-wide centralized fresh air systems or individual fresh air units on different floors.
• Shopping malls, shopping centers, and supermarkets : With their large spaces, frequent foot traffic, and dense concentration of goods, they are prone to generating odors, dust, and stuffiness. Fresh air units can refresh indoor air over a large area, keeping the space bright and comfortable and enhancing the customer shopping experience.
• Hotels, guesthouses, and inns : Guest rooms are mostly enclosed spaces, and residual formaldehyde, musty smells, and bedding odors are difficult to dissipate. Guests also have high requirements for air quality and comfort. Silent fresh air units can ventilate 24 hours a day, keeping the indoor air fresh even without opening windows, and there is no draft that will affect the stay.

II. Educational and Medical Facilities

These types of venues have extremely high requirements for air quality, hygiene standards, and ventilation safety. In addition, the immunity of the population varies, so it is necessary to rely on fresh air units to achieve a sterile, clean, and constant temperature ventilation environment to prevent cross-infection of germs.

• Schools, kindergartens, and training institutions : Students have weaker immune systems, and classrooms are often densely populated. Opening windows for ventilation can be affected by smog, noise, and rain or snow. Fresh air systems with sterilization and PM2.5 filtration functions can continuously exchange air in enclosed environments, reducing the probability of cross-infection of influenza and respiratory diseases, and protecting students' health.
• Hospitals, clinics, and health centers , including general wards, infusion rooms, outpatient halls, and rehabilitation rooms, are prone to harboring germs, odors, and the irritating smell of disinfectants in the air. Medical-grade fresh air units possess highly efficient sterilization, purification, and positive pressure air supply functions, effectively blocking outdoor germs and purifying indoor polluted air, providing a clean and ventilated environment for patients and medical staff while meeting hygiene standards for medical facilities.

III. Public Service and Recreational Venues

These types of spaces are enclosed, with concentrated populations and long dwell times. Traditional window ventilation is ineffective and easily affected by external environmental factors. Fresh air units can stably improve the indoor air environment and are suitable for various large public enclosed spaces.

• Cinemas, KTVs, card rooms, and gyms : Entertainment and fitness venues are mostly fully enclosed with no natural ventilation windows. The activity of people quickly increases the concentration of carbon dioxide, sweat odors, and dust. Fresh air systems can rapidly replace stale air, dispel odors, and prevent stuffy, hot spaces, making them suitable for high-intensity, long-term operation.
• Libraries, museums, exhibition halls, and art galleries : These venues not only need to ensure the breathing comfort of people, but also require constant temperature and humidity and clean air to prevent dust, moisture, and polluted air from damaging books, cultural relics, and exhibits. Fresh air units can precisely control temperature and humidity and filter dust, taking into account both the experience of people and the protection of collections.
• Train stations, airports, government service halls, and bank branches : Public service halls have extremely high traffic and poor air circulation, which easily accumulates dust and odors. High-volume fresh air units can achieve full-area air circulation and replacement, improving the comfort of the public environment.

IV. Industrial Production and Special Storage Facilities

Industrial and warehousing facilities have specific requirements for ventilation, dust removal, dehumidification, and air exchange. Dedicated industrial fresh air units can be adapted to special environments and meet the environmental standards for production and storage.

• Cleanrooms, precision instrument workshops, and electronics factories : Production operations require extremely high precision in air cleanliness, dust content, temperature, and humidity, prohibiting the opening of windows for ventilation. Industrial fresh air units can efficiently filter dust and particulate matter, maintain a positive pressure environment in the workshop, and ensure production accuracy and product qualification rate.
• Food and pharmaceutical production workshops : It is necessary to strictly control air cleanliness and sterilization rate to prevent air pollution from causing product deterioration or exceeding standards. Fresh air units with sterilization and purification functions can meet the hygiene and ventilation standards for food and pharmaceutical production.
• Archives, vaults, and temperature-controlled warehouses : Windows are prohibited in these places. They need to be protected against moisture, dust, and mold. Fresh air units can ventilate and regulate humidity in a closed environment to prevent archives and materials from getting damp, moldy, or damaged by dust accumulation.

V. Residential Housing

Home ventilation units are suitable for all types of modern residences, solving the problems of strong winds, noise, and dust when windows are opened in high-rise buildings, and the inability to ventilate in low-rise buildings due to mosquitoes and poor privacy when windows are opened, as well as the inability to ventilate on rainy or smoggy days.

• Fully furnished apartments, enclosed residences, and smart home homes : Modern residences have good airtightness, and the volatilization period of harmful gases such as formaldehyde and benzene after decoration is long. Household fresh air units can operate with low noise 24 hours a day, continuously diluting harmful gases and replacing indoor polluted air.
• High-rise residential buildings, street-facing residences, and villa areas : Avoiding the noise, dust, traffic safety, and privacy issues caused by window ventilation, achieving closed, quiet ventilation, and improving living comfort.
• Mother and baby room, elderly room, children's room : For people with sensitive constitutions, the special fresh air equipment can filter smog, pollen and germs, and provide a clean and constant temperature breathing environment, which is suitable for the healthy living needs of the elderly, children and pregnant women.
