Human Heat Gain
Heat gain from persons in air conditioned spaces - in btu/hr.
The table below indicates human sensible and latent heat. The values can be used to calculate heat loads that need to be handled by air conditioning systems.
| Typical Application | Sensible Heat (btu/hr) | Latent Heat (btu/hr) |
|---|---|---|
| Theater-Matinee, Auditorium, | 200 | 130 |
| Theater-Evening, School | 215 | 135 |
| Offices, Hotels, Apartments | 215 | 185 |
| Retail & Department Stores | 220 | 230 |
| Drug Store | 220 | 280 |
| Bank | 220 | 280 |
| Restaurant | 240 | 310 |
| Factory - light work | 240 | 510 |
| Dance Hall | 270 | 580 |
| Factory - moderate work | 330 | 670 |
| Bowling Alley | 510 | 940 |
| Factory - heavy work, Gymnasium | 510 | 940 |
- Tabulated values are based on 78oF (25.6oC) for dry-bulb temperature
- Adjusted total heat value for sedentary work, restaurant, includes 60 Btu/hr (18 W) for food per individual (30 Btu/h (9 W) sensible and 30 Btu/h (9 W) latent heat).
- For bowling figure one person per alley actually bowling, and all others as sitting (400 Btu/h) (118 W) or standing (550 Btu/h) (161 W)
