Individuals wearing encapsulating garments require auxiliary cooling systems to sustain physical and cognitive performance when exposed to high temperatures or workloads. Heat transfer in such cooling systems is typically based on either air or liquid as the heat exchange medium. Designing air-cooled systems requires knowledge of the quantity of heat to be extracted and cooling system design criteria, inlet air temperature and humidity and ventilation rates.
This paper addresses this issue by viewing the human as a simple time averaged heat source whose temperature must be maintained within a specified range. Integrating heat production over time permits heat extraction to be separated from physiological thermoregulation.
Framing physical workload and ambient conditions in terms of military relevant scenarios for rear cabin helicopter aircrew (25 yr old male working at 45% VO2max), families of curves were identified that define air conditioning system design criteria for given conditions.
穿着密封服装的人员在暴露于高温或高强度工作负荷时，需要辅助冷却系统来维持身体和认知功能。此类冷却系统中的热传递通常以空气或液体作为热交换介质。设计风冷系统需要了解要提取的热量、冷却系统设计标准、进气温度和湿度以及通风率。
本文通过将人体视为一个简单的时间平均热源来解决这个问题，该热源的温度必须保持在指定范围内。对产热随时间进行积分，可以将热量提取与生理体温调节分开。
根据后舱直升机机组人员（25岁男性，以最大摄氧量的45%工作）的军事相关场景来构建体力工作负荷和环境条件，确定了一系列曲线族，这些曲线族定义了给定条件下空调系统的设计标准。
