The SARS-CoV-2 (Covid-19) pandemic continues without slowing down, and we are encountering an increasing number of cases every day. Within this period, the risk of contamination in closed areas has drawn attention especially to the air conditioning systems in these areas. In the current situation, the best weapons we have against the virus are mask, physical distance, and hygiene. However, it is possible to reduce the risk of contamination with ventilation and air conditioning systems in closed areas. Considering the size of the virus, filtration and the use of UV-C lamps and increasing the fresh air flow in the indoor area have shown that the risk of transmission of the virus is significantly reduced. Hospitals are the buildings where the virus load is the most intense by its nature. Although the spaces in the hospital have a central air conditioning system, some measures should be taken within this period and these devices, which were designed without considering pandemic scenarios, should be operated in a way to minimize the risk of contamination. Especially temporary solutions for negative pressure rooms, how to provide pressurization in intensive care units, measures that can be taken in air handling units, issues to be considered in the HVAC system, etc. many measures are discussed in this study. In addition, the design details of how the exhaust vent can be taken behind the patient's head when necessary in an intensive care unit that is planned to be operated according to the pandemic scenario are discussed. A demonstration of the Covid-19 infection risk calculation tool with examples in a closed area is also given. The points to be considered in the application of UV-C systems are specified.
