摘要

 In order to efficiently solve the thermal soak effect generated during summer parking in the passenger cabin, a cold jet cooling method based on dynamic control strategy is proposed, which involves dynamically controlling the swing speed and swing range of the cold jet, and the cooling characteristics of the passenger compartment are simulated and studied, the dynamic control strategy is optimized based on the Design of Experiments (DOE) method. Firstly, the thermal soak characteristics of the passenger compartment during summer parking are simulated using the transient simulation method. Then, the cold jet cooling characteristics of the passenger compartment are simulated and analyzed based on both the traditional static control strategy and the dynamic cooling strategy. Finally, the Design of Experiments (DOE) method is employed to optimize the dynamic control strategy of the cold jet. The results show that the optimal dynamic control strategy can reduce the average temperature of the passenger compartment to 25.1 ℃ within 312 s. Compared with the traditional static control strategy, the cooling efficiency is improved by 27.4%, and the cooling amplitude is increased by 46.6%. The strategy not only effectively ensures thermal comfort of the passenger compartment, but also improves the cooling efficiency.
