Heating system and control strategy of electric vehicle air conditioner
The heating system in new energy vehicle air conditioners is different from that of traditional internal combustion engine vehicles. Therefore, some new energy vehicle air conditioners use circulating cooling water from traditional engines (such as hybrid vehicles) as the heat source. When the engine is not running, the semiconductor PTC element Heating, or heating from a hot water storage tank. Pure electric vehicles use heat pump air conditioning in addition to heating elements.
