Study on Thermal Comfort of Vehicle Interior Environment Based on Thermal Manikin

Abstract

The average daily stay time of city people in the vehicle is more than one hour. For some office workers in megalopolis, the stay time in the vehicle will be longer. Therefore, the thermal comfort of vehicle air conditioning system has an important impact on the life of residents. Using the warm manikin to test the comfort of the interior environment of the vehicle under different working conditions, test the steady-state conditions and compare with the comfortable equivalent space temperature of different parts of the human body, and give the air conditioning design optimization program. The results show that the cooling comfort in summer is relatively good, and the discomfort areas are mainly concentrated in feet, shins and other parts. In some cases, the thighs are overheated due to strong solar radiation, and the equivalent space temperature exceeds the comfort area.
