Method to Study Influenced Air-Conditioned Condition that Effects the Occupants Comfort in Tropical Climates Laboratory Room

Abstract

This study's design and experimental methods examine the multifactors of air conditioning that influence occupant comfort. The process of research integrates quantitative measurements, temperature, velocity, and humidity through occupancy combined with the CBE Thermal Comfort Tool to determine and compare the PMV comfort index at the ankle, waist, wrist, and neck on occupants' bodies in air-conditioned rooms with an airflow rate supply air of 600 - 1560 cfm. These methodologies, analyzed by ANOVA and Pareto Chart of Comfort Variables, thoroughly explain how specific air conditioning settings impact perceived comfort. The results show that the PMV comfort index on the occupants' bodies, between -0.5 to 0.5, occurs at the ankle, wrist, waist, and neck for both standing (adjusted R-sq 99.96%) and sitting positions (adjusted R-sq 99.96%). Furthermore, the standing and sitting experiments revealed no significant difference in the PMV index values for various positions on occupancy bodies.
