Air Disinfection in Shopping Malls
Air disinfection plays a crucial role in ensuring public health within the bustling environments of shopping malls, where people spend a significant amount of their time. Despite the common belief that air-conditioned spaces offer higher air quality, indoor air, particularly in shopping malls, is often more polluted than outdoor air. The EPA lists indoor air among the top five environmental risks, highlighting the essential need for air disinfection in shopping malls.
Shopping malls face heightened pollution levels due to contaminants like bacteria, fungi, mould, and viruses circulating in the air. These pollutants can contribute to health issues such as eye irritation, nasal congestion, headaches, dizziness, and fatigue.
Ozone generators emerge as a viable solution for air disinfection in shopping malls, particularly when integrated into HVAC systems. The primary pollutants in shopping malls include Volatile Organic Compounds (VOCs), originating from various sources like building materials, cleaners, plastics, and more. High concentrations of VOCs in indoor air can lead to allergies, asthma, and respiratory problems.
All these symptoms are called “SICK BUILDING SYNDROME”.
Carbon dioxide (CO2) levels also impact indoor air quality, with elevated levels causing symptoms such as headaches, restlessness, difficulty breathing, and fatigue. Additionally, unpleasant odours from food, body, cleaning materials, mould, and fungi contribute to what is known as “SICK BUILDING SYNDROME.”
To address these concerns, ozone generators play a vital role in oxidizing VOCs, not relying on fresh air oxygen. Ozone’s stronger oxidizing capabilities result in the reduction of fresh air intake, meeting ASHRAE standards and decreasing the need for fresh air drops.
In specific areas like self-service dining spaces, where food odours can be overwhelming, ozone generators prove effective in eliminating odours and ensuring air disinfection. These generators, when strategically placed in HVAC-AHU ducts, combat cooking smells and prevent their spread throughout the ventilation system, simultaneously improving indoor air quality and reducing energy consumption.
Ozone also finds utility in general toilets, neutralizing odours, preventing bacterial and mould formation, and maintaining a hygienic environment. Similarly, in garbage rooms, notorious for persistent odors, ozone generators offer an ideal solution. Installing ozone generators in these spaces eliminates garbage odours, reducing the need for extensive air ducts and exhaust installations.
By leveraging ozone generators in shopping malls, not only can air disinfection be effectively achieved but indoor air quality is also enhanced, aligning with ASHRAE standards. This dual benefit can contribute to up to a 20% reduction in energy consumption, making ozone generators a sustainable and efficient solution for maintaining a healthy and odour-free environment in shopping malls.
