Exploring the Significance of Indoor Air Quality (IAQ) and Innovative Mitigation Approaches
The quality of indoor air, commonly referred to as Indoor Air Quality (IAQ), has emerged as a critical concern for public health officials, researchers, innovators, and architects. This heightened interest stems from our awareness of human exposure to indoor pollutants and the associated energy expenses.
High temperatures and humidity often result in fungus and mould growth, particularly in subtropical climates. In buildings like institutions, much of the internal heat comes from human bodies, and we achieve thermal comfort by extensive use of air conditioning and recycled air. Economizers in air conditioning systems mainly revolve around recycled air use and ventilation.
Novel desiccant-assisted dehumidification and cooling systems present an economical, eco-friendly, and easily implementable solution in tropical climates to improve IAQ and reduce moisture from the air. This revolutionary technology could soon replace traditional vapour compression cooling systems, maintaining comfortable human thermal conditions and enhancing IAQ. Solar desiccant cooling systems are also emerging as energy-efficient, green options.
Defining Indoor Air Quality
IAQ is a vital consideration for health, posing risks if not properly managed. It can exacerbate symptoms of allergies, asthma, and other respiratory ailments. In healthy individuals, it can cause headaches, fatigue and dizziness. Such frequent instances may lead to nose, eye, and throat irritation. IAQ refers to the state of air affecting the health and comfort of the space or building occupants due to exposure to airborne pollutants and certain building materials that can pose significant health risks, such as respiratory illnesses.
Simply put, acceptable IAQ has no known contaminants at harmful levels. It also considers thermal comfort, average concentrations of respiratory gases like oxygen and carbon dioxide, and acceptable limits of air pollutants. IAQ is a variable, complex interaction of factors impacting indoor pollutant’s types, levels, and significance. It’s a significant concern for developers, business owners, building managers, tenants, and employees as it influences health, comfort, and productivity.
Approaches to Enhance Indoor Air Quality
Initiating the improvement of IAQ begins with effective dust management. Weekly dusting and vacuuming with a filter bag are recommended. It’s also crucial to avoid inadvertently introducing contaminants through household cleaners and deodorants. Regular HVAC air filter replacements based on visual inspections, and ensuring proper mechanical ventilation are vital. TDS Asia also advises seasonal heating and cooling system maintenance and periodic duct cleaning.
Dehumidifiers can effectively manage higher humidity levels during summer. These devices work alongside air conditioners to reduce the workload on the air conditioner, prolonging its lifespan.
Air scrubbers, a technology initially developed by NASA for the International Space Station, uses germicidal ultraviolet light to ‘scrub’ the air through a catalytic process. They can remove many contaminants, including volatile organic compounds, thereby improving occupants’ quality of life and health.
Regular replacement of air filters is crucial to prevent dust and other harmful contaminants from entering the HVAC system.
Desiccant Based Dehumidification and Cooling Systems
Desiccant materials with low moisture content draw moisture from the processed air due to the moisture pressure difference between the surface of the processed air and the desiccant material. Desiccant cooling systems use these materials to dehumidify and cool the air. After the desiccant material dries into the air, it becomes warm. Cheap air-cooling techniques like evaporative or heat exchangers cool this dehumidified air to near ambient temperatures, enhancing the conditioned space’s comfort level.
Conclusion
Desiccant-assisted dehumidification and cooling systems offer alternative solutions to traditional air conditioning systems by leveraging renewable energy resources and environmentally friendly materials, improving IAQ, saving energy, and reducing gas emissions. These systems’ energy performance can improve with lower regeneration temperature approaches, more efficient solar thermal collectors, market availability, and lower setup costs.
