The design requirements of indoor building ventilation system in the treatment place are upward air supply and downward air return.
Design principles of indoor building ventilation system for treatment places:
1, determine the principle of ventilation path:
Treated fresh air enters from the clean area, and the exhaust air is discharged from the dirty area. Strictly ensure that the clean area air flows to the sub-clean area, and then to the polluted area, forming a clear gradient pressure difference, to eliminate air cross-contamination.
2, air-conditioning zoning is reasonable:
For each department of the hospital, the function of each room, indoor air-conditioning design parameters, equipment profiles, health requirements, the use of time, air-conditioning loads, such as detailed investigation and research, repeated comparisons, and reasonably partition the system to ensure that the parameters required by each room to reduce the adverse impact of the different areas between.
3, determine the principle of ventilation time:
Determine the ventilation time according to the use of the room requirements, to ensure that the indoor air quality in the use of time healthy and hygienic.
4, the principle of energy-saving regulation:
Automatic adjustment of air volume size according to the air condition and the number of people in each area.
5, determine the principle of minimum ventilation:
In order to meet the demand for the minimum fresh air standards, taking into account the number of polluted environments, the number of air changes, air gradient pressure difference and other factors, to reasonably determine the minimum amount of ventilation.
6, the system is flexible and have the amount of preparation:
The flexibility of the system is mainly expressed in the change of medical technology and diagnostic and therapeutic equipment to update the adaptability.
