The Effect of the Distribution of Air Temperature in the Isolation Room on the Condition of the Air Supply

Isolation rooms for patients with infectious diseases in particular have a very high risk of being contaminated with various diseases such as Covid-19. Covid-19 is a severe respiratory disease caused by the coronavirus family that has become a worldwide pandemic. This type of disease spreads very quickly through the air. Isolation rooms for patients with infectious diseases must be prepared to prevent the spread of disease through the air. The air supply in the isolation room greatly affects the temperature and humidity of the air. This study aims to determine the air supply to the distribution of temperature and humidity in the isolation room. The research scheme was carried out in two conditions: Firstly, the isolation room was in normal condition without any air entering or leaving (diffuser–exhaust Off) and secondly, the condition of the isolation room being supplied with air (diffuser On–exhaust Off). The results of the first scheme show that there are slight differences between each of the measurement points (T1, T2, T3, and T4). The maximum temperature at point T1 is 27.85 °C, at positions X = 0.2 and Y = 1.9, while in other positions, there are no significant differences. This is because the positions X = 0.2 and Y = 1.9 are the locations of the measurement point on the patient’s bed. The results of the second scheme in the diffuser area show that there is a significant change in temperature, recorded at the measurement point T1. The minimum temperature reaches 21.18 °C, while for the measurement points T2, T3 and T4, the minimum temperatures are 19.73 °C, 19.68 °C, and 19.63 °C, respectively. Other areas also experienced changes in temperature, and the highest temperature occurred at the measurement locations X = 0.2 and Y = 1.9, where these locations were at the top of the patient's bed and far from the diffuser position. Thus, the measurement results of each condition can be the initial basis for continuing further research.
