摘要：
The stock of electric vehicle is booming recently. However, the range of the electric vehicle is still a main barrier in its adoption. Air conditioning system is the second largest energy consumption device on vehicle, which will cause significant range reduction during operation. In this paper, the energy-saving effect of utilizing the recirculated air in air conditioning system is evaluated. The outside air ventilation rate based on CO2 limits and windshield anti-fog requirements are calculated, and the energy-saving effect of this strategy in 30 cities across China is evaluated using an annual energy consumption model. It is found that utilizing the recirculated air can save 14-46% heating energy when using PTC heater, and 33-57% heating energy in heat pump AC system. Throughout a year, utilizing the recirculated air can extend the driving range by 11-30%. (C) 2019 Elsevier Ltd and IIR. All rights reserved.
