Resumo(s)
This article considers the ideal storage conditions for multiple vaccine brands, such as
Pfizer, Moderna, CoronaVac, Oxford–AstraZeneca, Janssen COVID-19 and Sputnik V. Refrigerant
fluid options for each storage condition, thermal load to cool each type of vaccine and environmental
impacts of refrigerants are compared. An energy simulation using the EUED (energy usage effectiveness
design) index was developed. The Oxford–AstraZeneca, Janssen COVID-19 and CoronaVac
vaccines show 9.34-times higher energy efficiency than Pfizer. In addition, a TEWI (total equivalent
warming impact) simulation was developed that prioritizes direct environmental impacts and indirect
in refrigeration. From this analysis, it is concluded that the cold storage of Oxford–AstraZeneca,
Janssen COVID-19 and CoronaVac vaccines in Brazil generates 35-times less environmental impact
than the Pfizer vaccine.
