Aircraft cabin comfort analysis with human thermoregulation model

The studies about cabin thermal comfort are of great significance in the large aircraft market competition. A reasonable human thermal model is the key to analyze and evaluate the thermal comfort. Based on thermal characteristics experiment of human in the limited space, a human thermal model with the behavior of thermal regulation was established. The complex heat transfer was simplified into the heat transfer among three areas of high temperature core, blood perfusion and the equivalent organization. This model will not only overcome the limitation of the constant wall temperature or constant heat flux density, but in good agreement with the experimental results. Combined with a predicted mean vote(PMV) thermal comfort evaluation method without iterative equation proposed, the comfort in crowded space can be analyzed under the premise of ensuring the calculation speed. Simulation results show that the method can meet the speed requirement when the simulation is for a complex space environment, but also more accurately reflects the human physiological thermal regulation process.
