| Abstract: | An experimental system in which the thermal manikin was used as the key instrument was designed and built.The system can simulate low temperature environment under-18 ℃ using a refrigeration system.The temperature in the system was controlled by an automatic microcontroller system.Within the system,a thermal manikin was applied to simulate the human physiological activities including heat and sweat production.Several temperature and humidity detectors were set to monitor the environmental changes.In system tests,the temperature dropped with the velocity of approximately 1 ℃/min,and the performances of the preservation and maximum value of wind speed satisfied the demands.This experimental system will support potential researches that focus on human safety and physiological behaviors,and tests of emergency and rescue equipment,etc. |
