The present invention provides a passenger cabin thermal comfort evaluation and optimization system and method, including a passenger cabin 3D simulation model, a passenger cabin thermal comfort evaluation model, and a passenger cabin thermal comfort optimization model; wherein, the passenger cabin thermal comfort optimization model Contains a loop optimization acceleration algorithm. Using thermal flow field simulation and multidisciplinary optimization methods, the optimal air outlet temperature and wind speed are obtained in the CAS stage or TG1 stage, which is used to guide the calibration of the air conditioning controller, effectively shortening the controller calibration cycle and cost. In addition, there is a loop optimization acceleration scheme in the loop simulation, which can reduce the number of invalid simulation steps by predicting the simulation trend, thereby effectively shortening the simulation time and improving optimization efficiency.
Description
technical field [0001] The invention relates to the technical field of automobile air-conditioning systems, in particular to a thermal comfort evaluation and optimization system and method for a passenger compartment. Background technique [0002] With the advancement of science and technology and the development of the economy, automobiles, as an indispensable means of transportation, are increasingly entering every aspect of people's daily lives. As one of the main components that affect the comfort and safety performance of the car, the car air conditioner mainly regulates the air quality in the car compartment. Provide cooling, heating, defrosting, defogging, air filtration and humidity control functions for the car, so that the driver and passengers feel comfortable in the car. Thermal comfort reflects the subjective feeling of the human body on the thermal state of the environment in a sealed space. In the cockpit of a car, under the operating mode of the air conditio...
