| Abstract |
n this paper, we propose a mobile negative pressure isolation room to ensure the safety of healthcare workers (HCWs) and provide rapid medical service, and analyze the performance of a ventilation system that can minimize virus cross-contamination through numerical analysis. The negative pressure isolation room uses a ventilation system with air flowing from the HCWs to the patient, a clean-contaminated zone separation, and pressure differential control applied to the anteroom/isolation room. CFD) simulation results showed that the negative pressure isolation room, which needs to maintain negative pressure, can prevent cross-infection by using a ventilation system with a rate of 6 ACH and maintaining a pressure differential of -2.5 Pa or higher with the anteroom/corridor, regardless of toilet exhaust operation. It is recommended to operate the toilet exhaust at all times to maintain the pressure differential in the existing hospital rooms. However, the independently configured mobile negative pressure isolation room operates efficiently even if the toilet exhaust fan is not in operation, making it a more energy and noise-efficient option. |
