A vehicle HVAC system includes a housing that introduces air from outside into a passenger compartment, a blower that blows air into the housing, an evaporator disposed in the housing, a heater core disposed downstream of the evaporator, and a front seat side temperature door and a rear seat side temperature door disposed between the evaporator and the heater core. A control method of a vehicle HVAC system includes: after an external condition of a vehicle satisfies or reaches a reference high temperature condition, determining, by a controller, whether a rear seat side cooling demand temperature is set to be lower than a front seat side cooling demand temperature; and reducing, by the controller, a target temperature of the evaporator based on the set rear-row seat-side cooling demand temperature when the rear-row seat-side cooling demand temperature is set to be lower than the front-row seat-side cooling demand temperature.

    一种车辆HVAC系统包括:将空气从外部引入乘客舱内部的壳体、将空气吹入壳体内的鼓风机、设置在壳体中的蒸发器、设置在蒸发器下游的加热器芯以及设置在蒸发器和加热器芯之间的前排座椅侧温度门和后排座椅侧温度门。一种车辆HVAC系统的控制方法包括:在车辆的外部条件满足或达到参考高温条件之后,通过控制器,判断后排座椅侧冷却需求温度是否被设置为低于前排座椅侧冷却需求温度;以及当后排座椅侧冷却需求温度被设置为低于前排座椅侧冷却需求温度时,通过控制器,基于设置的后排座椅侧冷却需求温度,降低蒸发器的目标温度。
