| Abstract | The objective of this work is to develop an airborne infection isolation room (AIIR) with the air control system. The commercial sensors and the proportional integral derivative (PID) control were used in the control system. All sensors were calibrated before use for the system. User interface was developed by using LabVIEW. Key parameter for design of the control system was capability of pressure reduction, i.e. -2.5 Pa. Flow distribution in the AIIR with the variation of outlet position at 10, 60 and 100 cm height was also analyzed to find proper position. From design and development of the system, the tests showed that from the start of operation, the system with PID control decreased room pressure to each setpoint, i.e. -2.5, -4 and -6 Pa, in 15 seconds and maintained the pressure at the setpoint with stability. The outlet at 10 cm height showed low level of air dispersion and turbulence, while 60 cm height provided back flow and high dispersion of air. |
