The invention discloses a central-ventilation thermal load measuring method of an automotive passenger compartment. A temperature sensor, a humidity sensor, a pressure sensor and an electric heater are arranged at corresponding measuring points in a sample automobile; a central ventilation system blower of the sample automobile is started to be at a preset gear until the thermal balancing betweenthe outside and the inside of the sample automobile is realized; the electric heater in the sample automobile is turned on and works until thermal balancing between the outside and the inside of the sample automobile reaches again, changes of the temperatures, humidity values and pressures with time of all measuring points in the sample automobile during the process are recorded and correspondingchanging curves are obtained; a wind nozzle in an experimental cabin is adjusted and thus the vehicle-ahead face velocity of the sample automobile is changed to be a plurality of different preset windvelocities, and the steps from step three to step five are repeated by corresponding to each preset wind velocity to obtain a plurality of changing curves; and according to the changing curves, a central-ventilation thermal load of an automotive passenger compartment is obtained. Therefore, simple and effective measurement and calibration of the central-ventilation thermal load of the automotivepassenger compartment are realized; and thus the reference is provided for the automotive thermal load calibration type experiments.
Description
technical field [0001] The invention relates to the field of measuring the heat load of fresh air in an automobile passenger compartment, in particular to a method for measuring the heat load of fresh air in an automobile passenger compartment. Background technique [0002] With the continuous development of the automobile industry and the continuous improvement of people's material living standards, in addition to pursuing the safety and reliability of automobiles, people's requirements for the comfort of passenger vehicles are also increasing. Vehicle thermal comfort, as an important part of the comfort evaluation system, has received more and more attention from major vehicle manufacturers. The thermal load calibration experiment of the vehicle is an indispensable and important part of the performance development of the thermal comfort of the vehicle, and the calibration of the thermal load of the fresh air in the passenger compartment of the vehicle is subordinate to the...
