AIR QUALITY ANALYSIS IN CLOSED-SPACE CAT CAFES TO REASSURE AIRFLOW TO MAINTAIN THE HEALTH OF THE USERS

Abstract

The cat cafe is part of a new business strategy that has concerned the sanity issue, especially in indoor air quality. This study aims to simulate the flow of the indoor air environments including the airflow, apertures, and particles of Pet Saga and D’Meow Cat Cafe at Yogyakarta. The method of the study was through direct observation using a TVOC meter for PM 2.5, CFD simulation to assess the indoor airflow in 3 conditions of air velocity, and Air Changes per Hour calculation to assess the quality of the indoor air able to maintain the air sanitation. The results from this study show that the airflow movement inside the room depends a lot on the size of the apertures that existed along with the air velocity in the area which then has the possibility to affect the number of air micro particles although based on the result of the calculation for the Air Changes per Hour, both of the cat cafes have surpassed the standard of air changes in restaurant according to the Indonesia National Standard for ventilation.
