Abstract |
This study explores thermal sensation and compares it with PMV prediction across different metabolic rate activities in an air-conditioned
environment. The experiments, conducted in a climate chamber, simulated various metabolic rates and temperatures for each condition. Twelve
subjects, comprising six males and six females, participated, and environmental parameters and skin temperature were measured. Subjects
assessed their thermal sensation, comfort, and preference every three minutes. Results revealed differences between PMV values and actual
thermal sensations, with the gap widening as the metabolic rate increased. Additionally, the time for thermal sensation to reach neutrality, the
duration of maintaining a neutral thermal sensation, and subsequent changes in sensation varied among metabolic rates and individuals. These
findings highlighted limitations in the existing PMV model and offer insights into areas needing improvement for predicting thermal
sensations in environments with diverse metabolic rates and temperature fluctuations. |
