Description

Hospital air conditioner control system Technical Field The utility model relates to the technical field of air conditioning systems, in particular to a hospital air conditioning control system. Background The hospital environment, especially the critical areas of operating rooms, intensive Care Units (ICU), sterile wards, laboratories, pharmacies, etc., has extremely stringent and specific requirements for indoor air quality, temperature, humidity, and air pressure differences (differential pressure) between the different areas. The accurate air pressure gradient control is a core means for preventing cross infection, for example, an operating room needs to maintain positive pressure to prevent external pollutants from entering, and an isolation ward needs to maintain negative pressure to prevent pathogens from leaking. Traditionally, hospitals often use discrete and independent equipment to meet these needs, where an independent air conditioning unit is responsible for temperature regulation, an independent humidifier or dehumidifier controls humidity, an independent air exhaust or fresh air system regulates ventilation and pressure differential, and various sensors are also installed in a distributed manner. An operator needs to monitor the multiple dashboards separately and manually adjust the start-stop and parameter set-points of the multiple devices. The mode has the obvious defects that effective linkage is lacking among equipment, environmental parameters are large in fluctuation and lag in regulation and control, manual operation is tedious and easy to make mistakes, accuracy and stability of key parameters are difficult to ensure, energy consumption is high due to independent operation of each system, and more importantly, for critical differential pressure control, a dispersion system is difficult to realize rapid and accurate dynamic regulation so as to meet strict requirements of infection control.
