Vícesegmentový model pro predikci fyziologických odezev člověka a tepelného komfortu v nehomogenních prostředích

For the correct prediction of thermal comfort in non-homogenous environments is recommended to use a multi-segment physiological model in combination with a thermal comfort model. In the paper, the authors refer to coupling of modified 65MN Tanabe model and thermal comfort model by Zhang. Both models are designed for non-homogenous environments and for transient changes of boundary conditions. The coupled model predicts human physiology responses, distribution of surface temperatures and thermal comfort. It is implemented in the Modelica language by using the Dymola as development tool. The model was tested for homogenous environments before and this paper presents testing of the model for non-homogenous environments. The coupled model results were compared with simulations carried out in Theseus-FE that uses the Fiala model as a virtual thermal manikin. The coupled model is suitable for automobile applications, e.g. design process of passenger compartment and air-conditioning system.

Pro korektní predikci tepelného komfortu v nehomogeních prostředích je doporučeno využívat vícesefmentový model fyziologie člověka v kombinaci s modelem tepelného komfortu. V posteru autoři poukazjí na využití modifikováného 65-uzlového Tanabeho modelu a modelu dle Zhang. Oba modely jsou vhodné pro nehomogenní prostředí a pro časově proměnné okrajové podmínky. Model predikuje fyziologické odezvy, rozložení povrchových teplot a vnímání tepelného komfortu. Model je implementován v jazyce Modelice v programu Dymola. Model byl již testován pro homognní prostředí. V posteru je prezentováno testování pro nehomogenní prostředí kabiny automobilu. Predikce propojeného modifikovaného Tanabeho a Zhang modelu byly porovnány s komerčním softwarem Theseus-FE, v kterém je implementován virtuální manekýn (model fyziologie a komfortu dle Fialy). Model je vhodný pro aplikace návrhu vnitřního designu kabiny automobilů či klimatizační jednotky.
