【Abstract】 The model of 3-dimensional air--flow and heat transfer inside the car chamber is established, the conjugation characteristics of the automotive refrigeration system and theair--flow field and the temperature distributions inside the passenger compartment is studied. The cooling down process of the passenger compartment is simulated based on thethree--dimensional distributed chamber model. An environment simulation experimental setis established and cooling--down process is measured. The agreement between the numericalresults and the experimental ones shows that the model established herein can be utilized asa tool in the automobile design and the selection of its automotive refrigeration system.更多还原
