The whole world at present is dealing with the COVID 19 pandemic. As per studies
worldwide SARS-CoV-2 by sequencing analysis is 95% homogenous similar to the bat
coronavirus and almost 70% similar to the SARS-CoV-1. SARS CoV 2 is a respiratory
problem which in its worst form of disease causes ARDS and hampers the patient's
ability to breathe on his own and has to be put on Ventilator. As per WHO (World
Health Organization) guidelines, sanitization is an effective way of prevention
from the infection. The proper sanitization being not feasible and time consuming
in certain cases, faster and effective alternatives of sanitization processes are
necessary. As per recently published study by researchers in Beijing, China, it
was observed that with each degree rise in temperature and percent humidity, the
contagiousness of the disease caused by the Coronavirus, named COVID 19 goes down
significantly. R-naught or R(O) can be referred as the average number of people
that gets infected from one sick person among a population which is not immune to
the virus. The closer to zero an R(O) value the better the results indicating
less spread of the disease. A lower R(O) means the outbreak is slowing or
declining while a higher one means its swelling or growing at faster rate. The
R(O) of the coronavirus hovers between 2 and 2.5 as per World Health Organization
or WHO meaning that each new person spreads the disease to about 2.2 people on an
average. The chamber being developed is aimed at lowering the R(o) value so that
the infection rate slows down. R(O) is not a fixed value, it changes depending on
various factors such as proximity among people, the environmental surroundings
and climatic conditions. The higher temperatures (38?°C) at 80-90% relative
humidity decreases the virus activity within 24?h. Moreover, in a condition where
the virus that was dried was stored at higher temperature (>38?°C) and high
relative humidity (>95%), there was observed an additional degradation in virus
activity at each point in time. Taking into consideration the above research, we
developed a COVID De-Incubator chamber to disinfect the clothes and commonly used
daily wear items. Our results were exciting as the disinfection proved to be
effective at temperatures of 75?°C-80?°C and humidity levels at 80%-90%.
Moreover, the chamber was developed at significantly lower costs. In this study,
an attempt has been made to fabricate a chamber with temperature and
humidity-controlled environment to disinfect daily used material. Using fins and
momentum source, a homogenous environment is created inside the chamber for
better results, with the help of numerical simulation to decide the optimum angle
for the inclination of fins and location of the momentum source.
