高大空间恒温空调气流组织设计方法研究

提出了一套通用的高大空间恒温空调气流组织设计方法：在气流组织初步计算的基础上，用数值分析的方法得到最优的设计方案，并用模型实验进行验证或修正。该方法用于某高大空间实验室证明是可行的。研究同时发现，室内的温度场和速度场同时受到冷射流和热源的影响，因此以往单纯用射流理论进行的气流组织实际计算结果不能直接应用于精度要求较高的恒温空调系统中。

Design method of air distribution of constant temperature air conditioning systems in high and large spaces

Proposes a general method for designing the air distribution system: using numerical analyses with general CFD software to optimise the design options based on a preliminary calculation of buoyant jet air motion, then verifying or modifying the selected option by model experiments, which proves to be practicable when used in the design for a laboratory of laser nuclear fusion. Also finds that the indoor temperature and velocity fields are simultaneously influenced by the cold jets and heat sources in the air conditioning space and concludes that the calculation results based on single isothermal air jet theory would cause larger errors therefore should not be used to high precision constant temperature air conditioning in large spaces.
