The paper is dedicated to adequacy analysis of Simulation Model of Human Body Thermoregulation System (HTSSM), intended for design of air/space Autonomous Life Support System (ALSS) The formal description of the HTSSM consists 51 equations to describe different body compartments, which consider different properties and individualities of human body as well as complexity dynamic characteristics of the studied functional system, and also includes the equation, which describes heat exchange processes in the heart and lung area. Active heat exchange mechanisms of thermoregulation system are described on the basis of fuzzy set theory. This paper discusses the HTMSS and its applications for: The analysis of a human heat state under heat stress conditions for a helmet area ventilation system design. The analysis of the temperature/moisture fields in the extra-vehicular suit for design of thermal control system. The results of computed experiments obtained using the HTMSS are also reviewed.
