Discussion on air conditioning and ventilation system design for large emergency isolation and treatment centres

This paper presents the medical process and characteristics of “three zones and two channels” in the outside clean area in the emergency isolation and treatment centres, proposes the new requirements of the pressure gradient control and airflow direction in the isolation and treatment centre, and discusses the applicability of the relevant provisions of the existing specifications, standards and guidelines.The ventilation modification scheme and operation mode of the all-air air conditioning system in the treatment area, and the ventilation mode and volume in the corridor area for medical staff are contrastively analysed.
