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|
|Offices, Hotels, Apartments||215||185|
|Retail & Department Stores||220||230|
|Factory - light work||240||510|
|Factory - moderate work||330||670|
|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)
