The 1D CFD implemented in complex vehicle models running on multiple software domains via co-simulation is presented. A two-zone cabin compartment model capable of predicting the average thermal conditions during various drive cycles has been created. Sensitivity analysis was carried out to identify the parameters with a significant impact on the cabin thermal response. The cabin model has been calibrated and validated with thermal performance test data. The validated cabin model and a 1D CFD refrigeration circuit model have been integrated into the baseline HVAC system model. The baseline HVAC system performance has been validated against climate chamber physical test data. A theoretical performance comparison between the baseline HVAC system and an electrified HeVAC system have been carried out. The key difference between the systems is that the HVAC system uses a conventional mechanically driven swashplate compressor and the HeVAC system uses a high-efficiency electric scroll compressor. The CoP and the cabin thermal response have been evaluated for both systems. |
