AI Technical Summary
Existing electric light passenger vehicle air conditioner defrosters have large evaporator core areas, occupy a lot of space, and heat pump air conditioners are ineffective in low-temperature environments, have high energy consumption, and short battery life.
Design a three-core electric defroster, comprising an evaporator core, an indoor condenser core, and an auxiliary PTC electric heating core, with a reasonable layout to balance cooling and heat pump functions. The air outlet mode is controlled by a cooling/heating motor and a mode motor to assist the heat pump air conditioner in addressing performance limitations in low-temperature environments.
It effectively reduces energy consumption, increases battery life, ensures defrost performance, makes reasonable use of space, and ensures that the airflow is not affected.
