ABSTRACT
COVID-19 has become a health threat around the world. Mask deficiency can be expected during a pandemic infection. The stability of viruses at different temperatures and relative humidity was assessed according to the type of contaminated surface material. With increasing temperature, the permanence of viruses decreases, and in proportion to the increase in temperature should not be damage to the quality of objects. Solar disinfection is one of the new methods of using renewable resources. By designing an integrated solar drying system with the phase change material, the internal temperature of the system reaches 54 °C in April and the masks are disinfected with 3036 Wh/m2 internal cumulative solar radiation. By using the appropriate equipment in the system, the temperature difference inside and outside the system was reached 30 °C. A correlation coefficient of 95% in the MATLAB confirmed that the curve fit was good. The main purpose of this research is to identify appropriate solutions for disinfection and consultation with scientific literature. The results showed that the most appropriate hygienic and economical disinfection method was the use of solar energy. © 2021 Published by Semnan University Press. All rights reserved.
