C-HVAC: A practical tool for assessing ventilation capacity for HVAC systems during the COVID-19 Pandemic
Embedded Network Sensor Systems(2020)
Abstract
ABSTRACTAlthough many health organizations are advising commercial and public sectors to maximize the outdoor air circulation and ventilation rates, such actions may not be completely feasible and impose a significant energy load on the HVAC systems. While the social distancing measures are being implemented, the aim of this paper is to present a feasible and practical solution for various stakeholders to calculate the maximum number of people that can occupy buildings during the COVID-19 pandemic when the HVAC systems of buildings work based on outside air or a combination of outside and recirculated air. As a result, C-HVAC, as an easy-to-use tool, was developed using thermodynamic principles that can calculate the maximum number of people that can occupy buildings during the COVID-19 pandemic based on ASHRAE's Building Readiness recommendations. The current paper is part of ongoing research on preventing the spread of highly infectious airborne diseases such as COVID-19 in indoor environments. The beta version of the tool is made publicly available through this article.
