Guidelines for Evaluating the Thermal Environment of Enclosed Spaces

摘要

Thermal stress due to heat or cold may impact comfort, the ability to conduct operations, and, potentially, the survival of Warfighters. This report provides background information and methods for characterizing the properties of enclosed spaces (vehicles, shelters, other enclosures) that impact the thermal state of Warfighters. Quantification of the thermal environment of an enclosure consists of measuring air and surface temperatures, humidity, air flow; and radiant load. Methods focus on obtaining enough data to define each microclimate within the target space. Three studies of concrete tanks and metal containers, the High Mobility Multipurpose Wheeled Vehicle; and the Bradley Fighting Vehicle, are described.
