In order to reduce the energy consumption of heat pump air conditioning systems,take the heat pump air conditioning system matching Active Grille Shutter(AGS)thermal management system of electric vehicles as the research object,a heat pump air conditioning thermal management system and energy consumption control strategy are developed based on various parameters including vehicle speed and intake grille opening area.The energy consumption values of the system are simulated and calculated for different AGS openings in high and low temperature environments.Using the calibration method in the actual vehicle cabin environment,this paper analyzes the variations in measured values of air conditioning systems and wind resistance energy consumption for AGS openings in low temperatures of-7 ℃ and high temperatures of 35℃.The experimental results show that in high and low temperature environments,the larger the AGS opening,the higher the wind resistance energy consumption value,whereas the lower the comprehensive energy consumption value of air conditioning and wind resistance.When the AGS opening increases by the same value,the impact on energy consumption at high temperatures is greater than that at low temperatures.
