Disease Resilient and Energy-Efficient Centralized Air-Conditioning Systems
How can innovative technologies be utilized to achieve disease-resilient and energy-efficient centralized air-conditioning systems in public buildings
THE CONTEXT
Studies show that transmission of viruses, such as the coronavirus causing COVID-19, can be prompted by centralized air-conditioning systems. In developing member countries (DMC), the risks of virus transmission are higher because of poor hygiene including the use of old air-conditioning equipment, lack of regular maintenance, and overcrowding in closed spaces.
Inefficient centralized air-conditioning (CAC) systems in many DMCs account for up to 50% of energy consumption in public buildings. Advanced air-conditioning systems with energy-saving technologies used in combination with demand-side management techniques could bring up to 45% energy savings. CACs also rely heavily on hydrofluorocarbons (HFCs), which are greenhouse gases that can be thousands of times more potent than carbon dioxide. Proper management of HFCs is critical to addressing greenhouse gas emissions from CAC systems.
