During the first fiscal year of the project, research has been directed towards redesigning and rebuilding the Snellen Air Calorimeter. At this time, we are on schedule having completed the reconstruction of the calorimeter and the installation of the mechanical operating system. The system is designed to be operational in a wide range of ambient conditions (5-30 deg C). Preliminary calibration has been started and will continue over the next months. Once completed the air calorimeter will be used to quantify the heat loss during physical work. The calorimeter will also be used to validate a portable calorimeter, the liquid-cooled garment calorimeter. By the end of this fiscal year, rebuilding of a liquid-cooled garment calorimeter will be completed. This system will offer temperature control based on cooling with offsetting proportional heating of the water flowing through the garment. Heat extraction can be measured separately for six body regions (head, upper torso, lower torso, arms, thighs, and legs). Regional heat extraction measurement will allow establishment of regional correspondence between muscle temperatures associated with work and the heat produced. |
