Improvements and Operation Methods of HVAC System in Shanghai Library(East Zone) Under the Background of COVID-19's Normalization Prevention and Control

ABSTRACT

In the first half of 2020, the construction of Shanghai Library(East Zone) was delayed by the COVID-19's outbreak. As time goes on, the epidemic is spreading in many parts of the world. Although the epidemic in China has been effectively controlled, such grave public health emergencies ring the alarm bell for social public. Relative authorities have issued guidelines, measures and specifications for how to use HVAC system under these circumstances. By analyzing these new codes and standards, the HVAC system in Shanghai Library(East Zone) can operate as design. Because the design outdoor air rates and filter's performance meet the standard requirements. At the end of Shanghai Library East's construction, some operation methods and adaptable improvements in filters are given to increase the security level. Five methods, including(1)enhancement of natural ventilation,(2)control of the occupant density,(3)installation of filters,(4)increase of the outdoor air rates for ventilation according to the risk level of epidemic situation,(5)cleaning, disinfection and inspection of the HVAC equipment. Given by this research can also be applied to similar public buildings.
