Research on Climate Comfort Evaluation of a EMU Train Cab Based on CFD Simulation and Equivalent Temperature
The indoor microclimate comfort of EMU train driver compartment is an important concern in the early stage of design, and the influence of the HVAC system on climate comfort should be predicted. By using simulative analyses early in design, it is relatively convenient to modify the design with lower cost, and can acquire many parameters which can't be acquired by tests. In this paper, the finite element model of an EMU train driver compartment was established, and the distribution of the indoor temperature and air-flow speed were simulated for both summer and winter conditions. Since only the comfort ranges of temperature and air-flow speed near the head and below calf regions were prescribed in the UIC651 standard, which was unable to be used to evaluate the climate comfort of detailed body parts of human body. For this reason, the equivalent temperatures of human body parts were calculated, and were used to evaluate the climate comfort of driver human body by comparing with the Nilsson comfort model. The above analyses showed that the layout and the HVAC design of the EMU train compartment met the requirement of climate comfort of driver. The results also showed good consistency of Nilsson model with the UIC651 standard in evaluating head and body parts below calf, while the model could be adopted to evaluate more parts of human body. The simulative calculation and the evaluation methods of the climate comfort presented in this paper provide good references for the design and analysis of driver compartment layout and the design of HVAC system.
