Establishes a CFD three-dimensional model of the induced ventilation system of the motor car inspection library under the cover, uses the thermal environment evaluation indicators such as dry-bulb temperature, wet-bulb-globe temperature, ventilation rate, ventilation efficiency and energy utilization coefficient to calculate and analyse the heat rejection effect of the induced ventilation system under different heat source intensities in the library. The results show that the induced ventilation system can effectively remove the residual heat in the warehouse and improve the thermal environment parameters of each work surface. Based on the research results, proposes the induced ventilation design scheme and key technical parameters for reference in engineering design.
