Thermal Environmental Control System in Airborne Infection Isolation Room

Article presents the development of the Airborne Infection Isolation Room (AIIR) thermal environmental control system. To support Covid-19 patients in the Airborne Infection Isolation Room (AIIR) Betong Hospital. The parameters to be controlled are according to the CDC and ASHRAE standard. Air pressure in the Isolation room
$< -\mathbf{2}.\mathbf{5}\mathbf{Pa}$
Air Temperature Relative Humidity and Air Chang Rate are 21-24°C, 40-60

RH and 12 ACH respectively [1], [2]. The dehumidification system is a Desiccant wheel (DW) with diameters of 60 cm containing 3 kg of silica gel. The result of the measurement experimental in AIIR found that negative pressure-6.5 Pa average temperature relative humidity and air changes rate is 37.78°C 48.06 %RH and 16.57 ACH respectively.
