Abstract

The invention relates to an automobile passenger compartment heating simulation method. The method includes: selecting a reference automobile model, building a passenger compartment model according to the reference automobile model, then creating a heating model of the reference automobile model according to the reference automobile model, checking the passenger compartment model for the reference automobile model, simulating outlet air temperature of a novel automobile model heater core, simulating air duct heat loss of the reference car model, establishing a novel automobile model passenger compartment model, and forecasting whole-automobile heating effect of the novel automobile model. Through the automobile passenger compartment heating simulation method, the heating simulation method in the automobile development process is simple and easy to implement, analysis period is short, and comparison of various schemes can be realized at the same time. Compared with the conventional method, the method has the advantages that influences on whole-automobile heating effect due to engine heat and water flow of all branches of the cooling system are taken into consideration, and transient effect of whole-automobile heating can realized.

Description

technical field [0001] The invention belongs to the technical field of automobile simulation, and in particular relates to a heating simulation method for an automobile passenger compartment. Background technique [0002] When the car is running in cold weather, the temperature inside the car is low. In order to maintain the comfort of the driver and passengers in the car, the temperature inside the car is required to reach a certain target value; the current car heating system mainly uses the waste heat of the engine to heat the cold air to reach The purpose of heating; the waste heat heating system is divided into water heating type and gas heating type according to the difference of heat transfer medium. The water heating system uses the coolant in the engine cooling system as the heat source, introduces the coolant into the heater core, exchanges heat with the cold air sent by the blower, and blows the heated air into the passenger compartment. The average temperature r...
