A New Tailored Approach to Calculate the Optimal Number of Outdoor Air Changes in School Building HVAC Systems in the Post-COVID-19 Era

Energies, Journal Year: 2024, Volume and Issue: 17(11), P. 2769 - 2769

Published: June 5, 2024

Air conditioning systems can play a positive or negative role in the spread of COVID-19 infection. The importance sufficient outdoor air changes buildings was highlighted by World Health Organization, therefore these should be guaranteed mechanical ventilation adequate systems. proposed case study concerns optimal number to limit contagion for school building Central Italy. Wells–Riley model is used assess risk airborne infection, while energy consumption calculated dynamic simulation software. scope paper offers an innovative method define strategy building’s HVAC system design reduce infection with limited increases and greenhouse gas emissions. Results show that desirable approach one which same low value set all rooms. This new results significant savings, compared most common ones (setting high rates rooms) counteract Finally, zero-emission target verified introducing suitable photovoltaic offset pollutant

The Relationship between Mechanical Ventilation, Indoor Air Quality Classes, and Energy Classes in a Romanian Context

Atmosphere, Journal Year: 2024, Volume and Issue: 15(4), P. 444 - 444

Published: April 3, 2024

Nowadays, indoor air quality (IAQ) and the energy performance of buildings are two main scientific technical challenges because they in direct connection with human health depletion resources. In this study, we analyzed influence an outdoor flow introduced through a mechanical ventilation system, focusing on aforementioned topics. A standardized rate (25 m3/h/person) led to increase O3 concentration (from 5 μg/m3 50 μg/m3) and, simultaneously, decrease CO2 2000 mg/m3 800 mg/m3), PM2.5 300 150 μg/m3), maintenance constant HCHO concentration. our new, single index, IIAQ, is proposed. This new index presents different implications: one hand, it has ability simultaneously take into account several pollutant species, other can prioritize strategy that responds extreme values certain pollutant. Moreover, classes were elaborated, similar classes. The possibility using consumption may lead strategies adaptative dynamic concentrations.

Effect of Different Mechanical Fans on Virus Particle Transport: A Review

Buildings, Journal Year: 2025, Volume and Issue: 15(3), P. 303 - 303

Published: Jan. 21, 2025

In recent years, repeated outbreaks of airborne viruses have normalized human coexistence with these viruses. The complex turbulence and vortices generated by different fan types operation modes affect virus removal effectiveness. This paper reviews the potential impact actual effectiveness fans in mitigating indoor transmission, highlighting their advantages limitations. Downward rotating ceiling can rapidly dilute concentration (21–87%) breathing zone due to jet cores, efficiency depending on rotational speed particle diameter. However, reprocessing problems large particles being deposited surfaces, small settling rebounding into air remain unresolved. Upward-rotating do not contribute removal. Exhaust generate a negative-pressure environment, which helps expel quickly. But improper vortex zones increase retention time 16–40 times. Air-apply effectively transport only when delivering airflow exceeding 0.5 m/s directly zone. Additionally, combined strategies underexplored, despite benefits. review underscores need for standardized definitions calls further research how climatic conditions thermal comfort influence fan-based interventions.
