Simulation verification method and simulation verification system for defrosting performance of automobile air conditioner

Abstract

The invention relates to a simulation verification method and system for the defrosting performance of an automobile air conditioner, and the method comprises the following steps that: a simulation model is built, and the grid division is carried out; steady-state flow field simulation calculation is conducted on the simulation model, and the wind speeds of the area A, the area A' and the area B of the front windshield and the area percentages of the wind speeds are obtained; whether the area of the area with the wind speed greater than the first wind speed accounts for a first proportion of the area of the area A in the area A or not, in the A' area, whether the area of the area with the wind speed larger than the second wind speed accounts for a second proportion or above of the area of the A' area or not, and in the B area, whether the area of the area with the wind speed larger than the third wind speed accounts for a third proportion or above of the area of the B area or not are judged, if yes, transient flow field defrosting simulation verification with a temperature field is conducted on the simulation model to confirm whether the simulation model meets the regulation requirements or not; otherwise, the simulation model is re-established. The problems that in the related technology, time and labor are wasted in simulation verification and optimization design, and the design and development period of an air conditioner system is long can be solved.

Description

technical field [0001] The present application relates to the field of automobile technology, and in particular to a simulation verification method, storage medium, electronic equipment and simulation verification system for the defrosting performance of an automobile air conditioner. Background technique [0002] If the defrosting effect of the car is not good, it will seriously affect the driver's sight, and then affect the driving safety of the car. Therefore, the defrosting performance of the car air conditioner needs to meet the relevant mandatory regulations. Therefore, whether it is a traditional vehicle or a new energy vehicle, the defrosting performance of the air conditioner is the focus of attention in the design of the air conditioning system. [0003] At present, after the initial design model of the air conditioning system is established, simulation analysis is required to judge whether the design meets the requirements of the regulations, that is, within 20 mi...
