2. Objectives
•
Evaluate thermal sensations and thermal comfort in a mist spraying environment
•
Confirm cooling effects by measuring environmental factors:
◦
Air temperature
◦
Relative humidity
◦
Mean Radiant Temperature (MRT)
◦
Air velocity
•
Develop and validate a physiological human model considering mist wettedness
(Comparison of skin temperature in/outside the mist zone)
3. Methodology
•
Field surveys before and after mist exposure
•
Number of subjects: 1,110
•
Comparative analysis:
◦
Subjective votes (mTSV & CSV)
◦
Objective environmental measurements
◦
Skin temperature trends (0–10 min outdoor vs 10–20 min mist zone)
4. Key Findings
•
Thermal Sensation:
◦
‘Hot’ reduced from 98% → 33% after mist exposure
•
Thermal Comfort:
◦
‘Discomfort’ reduced from 82% → 14%
•
Environmental Effects:
◦
Air temperature ↓ 3.6°C
◦
MRT ↓ 1.0°C
◦
Humidity ↑ 15.9%
•
Human Model:
◦
Developed a 3-node thermal model with/without mist wettedness
◦
Accurately estimated thermal state changes via skin temp analysis
