Abstract: The factors affecting the performance of human thermalregulation system in extreme thermal environment are analysed. Meanwhile, biological heat transfer problems concerning human thermalregulation simulation are studied. We obtain the results on human blood heat transfer, biological governing equations under the heat/vibration conditions, the heat transfer boundary conditions of clothes with active thermal control and so on. Based on the results, we suggest to focuse the effort on the human thermalregulation system under micro gravity condition in future studies.

Key words: human thermalregulation system, biological heat transfer, human blood heat transfer, vibration, liquidcooling garment, ventilation, micro2gravity condition
