TLDR
In this paper, a thermal management of automobiles greatly improves the total energy efficiency of vehicles with internal combustion engines (ICEV) by using compression-type heat pumps (HPs) with an electric compressor as the air conditioner.
Abstract
Automobiles with internal combustion engines (ICEV) can use only around 30 % of fuel energy for operation, and under current conditions, around 70 % of the unused energy is lost as waste heat. Therefore, thermal management of automobiles greatly improves the total energy efficiency of vehicles with such engines. Even for an electric vehicle (EV) and hybrid electric vehicle (HEV), when compression-type heat pumps (HPs) with an electric compressor are used as the air conditioner, it is not effective if the vehicle uses energy a lot from an expensive battery.
