A SIMULATION OF EVA SPACE SUIT THERMAL CONTROL SYSTEM

In this paper, heat dissipation of the human on Liquid Cooling and Ventilation Garment （LCVG） are discussed by linking the mathematics models of human ther-mal control system, metal-hydride cold source and Liquid Cooling Garment （LCG）. By simulating the EVA space suit thermal control system working condition for 5.5h, the temperatures of every part in the body, the inlet and outlet of LCG and the outlet of the metal-hydride cold source were obtained. The result might be utilized in the design of EVA space suit thermal control system and further inves-tigation.
