In fuel vehicles,the heating of the air conditioning system uses the cooling water of the engine for heat ex-change.It is waste heat utilization and will not increase fuel consumption.The refrigeration system uses the engine to drive the air conditioning compressor for refrigeration.In new energy vehicles,due to the particularity of their structures,the composition of their air conditioning systems is quite different from that of traditional fuel vehicles.Air conditioning refrigeration uses an air conditioning compressor driven by a motor to achieve refrigeration.However,the components of heating systems come in various forms.Heating systems include those that use engine cooling water for heating(hybrid models),some that use PTC electric heating(pure electric and plug-in hybrid),some that use heat pump heating sys-tems,and some that are a combination of multiple heating systems,etc.
