Abstract

This study presents the performance of a low-cost airborne infection isolation room (AIIR). The system consists of an ante room, two AIIRs, a blower, two butterfly valves, an air conditioner, a controller, and a ventilation system. Pressure and temperature sensors were calibrated and installed in all rooms. The control was an in-house system, including Arduino Uno R3, ESP32, NI-USB 6009, and PLC FX5U. PID control was employed to regulate the pressure inside the AIIRs by adjusting the outlet air blower speed. The system was tested under various negative pressures, i.e. -2.5 to -10 Pa, and the effect of inlet opening was also investigated. The results showed that the system effectively controlled the pressure under all experimental conditions. The blower speed and room pressure were found to be related, with higher blower speeds required when all butterfly valves were open. The current of the motor increased with the valve set connected, and the highest current was observed when all butterfly valves were open. The air velocity generated by the blower suction varied with the room pressure, with a decrease in pressure leading to an increase in air velocity. However, for one room operation, the velocity difference was insignificant.
