3826 (RP-619) -- The Transient Nature of Thermal Loads Generated by People PDF

States that prior environmental exposure and activity are important considerations when designing for human-generated thermal load in mass transit vehicles. These effects can result in loads that are several times larger than might be expected from steady-state data. Describes collection of experimental data using a calorimeter capable of holding 10 people. Develops a computer simulation model to predict human thermal loads in transient situations. Uses the experimental data to validate the simulation model. States this model should provide the needed design tool for determining the dynamic human-generated thermal loads that can be expected for vehicle environmental control systems.
