Few studies focus on the deposition of pathogen-laden aerosol during inhalation, especially for different respiratory infectious pathogens. This paper studied the depositions of H3N2, SAR-CoV-2, Ebola virus, Escherichia coli, and different sizes of droplets in the realistic human respiratory airway during inhalation. And results show that large droplets are mainly deposited in the upper respiratory tract, while most of the small particles, especially viruses, will transmit to somewhere further than bronchi-G7 and be deposited into the deep lobes of the lungs. Over 90% of single virus particles will inhale into lobes. The deposition efficiency of pathogens in the right lobes is significantly higher than that in the left, and this phenomenon is more obvious in the superior lobes, which may also explain why lung carcinomas are more likely to d...

In this paper, the ideal reversible processes of the three types of systems are built theoretically with their mathematical models, in order to compare their maximum coefficients of performance COPs. The results show that the COP1 of the ideal heat pump driven liquid dehumidification hybrid system is the maximum and the COP2 of the temperature-humidity independent control system is the minimum with the COP3 of the heat pump system falling between both. The COP1 increases by 100% with an increase in the indoor design temperature and relative humidity while the COP1 decreases with the increase in the ambient temperature and relative humidity. The COP2 of the temperature-humidity independent control system can be affected more significantly by supply air temperature difference and a...
