一些新能源车辆的热管理系统通常采用鼓风机将室外空气吸入进室内空间，并将室内空气排出，以实现换气模式的换气功能。当室外空气质量较差时开启换气模式，依旧会将质量较差的空气吸入进室内空间，使得室内空气恶化，舒适性较差。

参见图1和图2所示，本申请提供一种换气控制方法，应用于车辆。换气控制方法包括步骤S101和S102。
在步骤S101中，在所述车辆的换气模式下，获取室外空间21的环境状态。环境状态包括温度、空气质量和湿度中的至少一个。获取室外空间21的环境状态，可以包括：获取室外空间21的温度、获取室外空间21的空气质量、获取室外空间21的湿度中的至少一个。
在步骤S102中，至少根据室外空间21的环境状态，控制第一风门20，以使蒸发器14的进风侧与室外空间21和室内空间22中的至少一者连通。可以控制第一风门20旋转，以使蒸发器14的进风侧与室外空间21连通。也可以控制第一风门20旋转，以使蒸发器14的进风侧与室内空间22连通。还可以控制第一风门20旋转，以使蒸发器14的进风侧与室外空间21和室内空间22都连通。可以根据室外空间21的环境状态，控制第一风门20，如此可以在室外空间21的环境状态较差的情况下，控制第一风门20，以使蒸发器14的进风侧与室内空间22连通，而不与室外空间21连通，实现空气的内循环，防止将质量较差的室外空气吸入进室内空间22，提高了室内空间22的舒适性。也可以在室外空间21的环境状态较好的情况下，控制第一风门20，以使蒸发器14的进风侧与室外空间21连通。此时，冷凝器15的进风侧可以与室外空间21连通，也就是说，蒸发器14的进风侧和冷凝器15的进风侧均与室外空间21连通，使得空气进气量更大，可以更快速的换气。
在一些实施例中，获取室外空间21的环境状态，包括：获取室外空间21的空气质 量。可以通过设置于室内空间22的空气质量传感器28或设置于室外空间21的空气质量传感器，获取室外空间21的空气质量等级。空气质量传感器28可以检测空气中可吸入颗粒物、细颗粒物、二氧化硫、二氧化氮、一氧化碳中至少一种的含量。至少根据室外空间21的环境状态，控制第一风门20，包括：若室外空间21的空气质量等级为一级或二级，则控制第一风门20，以使蒸发器14的进风侧至少与室外空间21连通。其中，空气质量等级是根据空气质量指数(Air Quality Index，AQI)来划分的，通常分为六个等级：一级(优)，AQI在0至50之间；二级(良)，AQI在51至100之间；三级(轻度污染)，AQI在101至150之间；四级(中度污染)，AQI在151至200之间；五级(重度污染)，AQI在201至300之间；六级(严重污染)，AQI大于300。室外空间21的空气质量等级为一级或二级，表示室外空间21的空气质量较好。若室外空间21的空气质量等级为一级或二级，则可以控制第一风门20旋转，以使蒸发器14的进风侧与室外空间21连通，也可以控制第一风门20旋转，以使蒸发器14的进风侧与室外空间21和室内空间22都连通。如此可以在室外空间21的空气质量较好时，使室内空间22的空气与室外空间21的空气进行充分的交换，换气效果更好，从而可以改善室内空间22的空气质量。
若室外空间21的空气质量等级不是一级或二级，则控制第一风门20，以使蒸发器14的进风侧与室内空间22连通。其中，室外空间21的空气质量等级不是一级或二级，表示室外空间21的空气质量等级可以是三级、四级、五级或六级，也即室外空间21的空气质量较差。若室外空间21的空气质量等级不是一级或二级，则可以控制第一风门20旋转，以使蒸发器14的进风侧与室内空间22连通，如此可以在室外空间21的环境状态较差的情况下，实现空气的内循环。
在一些实施例中，所述换气控制方法还包括：获取室内空间22的温度。可以通过室内温度传感器，获取室内空间22的温度。获取室外空间21的环境状态，包括：获取室外空间21的温度。可以通过室外温度传感器，获取室外空间21的温度。可以先获取室内空间22的温度，再获取室外空间21的温度。也可以先获取室外空间21的温度，再获取室内空间22的温度，本申请不做限制。
至少根据室外空间21的环境状态，控制第一风门20，包括：根据室内空间22的温度和室外空间21的温度，控制第一风门20。若室内空间22的温度与室外空间21的温度之间的温差小于等于第一设定温度，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积大于蒸发器14的进风侧与室内空间22的进风面积。其中，温 差可以指室内空间22的温度与室外空间21的温度中，温度较高的一者减去温度较低的一者后得到的差值。若温差小于等于第一设定温度，表示室内空间22的温度与室外空间21的温度之间的温差较小，则可以控制第一风门20，使第一风道12内室外空间21的进风量大于室内空间22的进风量。如此，室外空间21的进风量更大，换气效果更好。
若室内空间22的温度与室外空间21的温度之间的温差大于第一设定温度，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积小于蒸发器14的进风侧与室内空间22的进风面积。若温差大于第一设定温度，表示室内空间22的温度与室外空间21的温度之间的温差较大，室外空间21的温度可能过冷或过热，则可以控制第一风门20，使第一风道12内室内空间22的进风量大于室外空间21的进风量。如此，在保证换气效果的同时，可以保证室内空间22的温度更加舒适，防止因过量导入过冷或过热的室外空气而影响室内空间22的温度，用户的使用体验更好。
在一些实施例中，若室内空间22的温度与室外空间21的温度之间的温差小于等于第一设定温度，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积大于蒸发器14的进风侧与室内空间22的进风面积，包括：若室内空间22的温度与室外空间21的温度之间的温差减小，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积增大；若室内空间22的温度与室外空间21的温度之间的温差增大，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积减小。
在一些实施例中，若当前室内空间22的温度与当前室外空间21的温度之间的温差小于上一时刻室内空间22的温度与上一时刻室外空间21的温度之间的温差，表示室内空间22的温度与室外空间21的温度之间的温差减小，则可以控制第一风门20，增大室外空间21的进风量，使得换气效果更好、更快。
在一些实施例中，若当前室内空间22的温度与当前室外空间21的温度之间的温差大于上一时刻室内空间22的温度与上一时刻室外空间21的温度之间的温差，表示室内空间22的温度与室外空间21的温度之间的温差增大，则可以控制第一风门20，减小室外空间21的进风量，使得室外空间21的温度对室内空间22的影响更小。
在一些实施例中，若室内空间22的温度与室外空间21的温度之间的温差大于第一设定温度，则控制第一风门20，以使蒸发器14的进风侧与室外空间21的进风面积小于蒸发器14的进风侧与室内空间22的进风面积，包括：若室内空间22的温度与室外空间21的温度之间的温差减小，则控制第一风门20，以使蒸发器14的进风侧与室内空间22的进风面积减小；若室内空间22的温度与室外空间21的温度之间的温差增大，则控 制第一风门20，以使蒸发器14的进风侧与室内空间22的进风面积增大。
在一些实施例中，若当前室内空间22的温度与当前室外空间21的温度之间的温差小于上一时刻室内空间22的温度与上一时刻室外空间21的温度之间的温差，表示室内空间22的温度与室外空间21的温度之间的温差减小，则可以控制第一风门20，减小室内空间22的进风量，使得换气效果更好、更快。
在一些实施例中，若当前室内空间22的温度与当前室外空间21的温度之间的温差大于上一时刻室内空间22的温度与上一时刻室外空间21的温度之间的温差，表示室内空间22的温度与室外空间21的温度之间的温差增大，则可以控制第一风门20，增大室内空间22的进风量，减小室外空间21的温度对室内空间22的影响。
在一些实施例中，换气控制方法还包括：获取室内空间22的空气质量。可以通过设置于室内空间22的空气质量传感器28获取室内空间22的空气质量。获取室外空间21的环境状态，包括：根据室内空间22的空气质量，确定室外空间21的空气质量。可以通过设置于室内空间22的空气质量传感器28获取的室内空间22的空气质量等级来确定室外空间21的空气质量等级，从而可以仅在室内空间22设置空气质量传感器28，节约成本。其中，若当前室内空间22的空气质量等级高于上一时刻的室内空间22的空气质量等级，则表示室外空间21的空气质量等级高于二级(即，室外空间21的空气质量较差)，此时，可以控制第一风门20旋转，以使蒸发器14的进风侧与室内空间22连通，利用空气的内循环，实现换气。在其他一些实施例中，若当前室内空间22的AQI高于上一时刻的室内空间22的AQI，则表示室外空间21的空气质量等级高于二级。
在一些实施例中，获取室外空间21的环境状态，包括：获取室外空间21的温度和空气质量。可以通过温度传感器获取室外空间21的温度，可以通过空气质量传感器28获取室外空间21的空气质量等级。
至少根据室外空间21的环境状态，控制第一风门20，包括：若室外空间21的环境温度低于第二设定温度、且室外空间21的空气质量等级高于二级，则控制第一风门20，以使蒸发器14的进风侧与室内空间22连通，且控制第二风门23切换至打开状态，以使第一风道12和第二风道13连通。当室外空间21的环境温度低于第二设定温度时，表示室外空间21的温度较低，可以控制第二风门23切换至打开状态，以使第一风道12和第二风道13连通。如此可以在室外空间21的温度较低的时候，利用蒸发器14加热冷凝器15，制热速度更快。同时，当室外空间21的空气质量等级高于二级时，表示室外空间21的空气质量较差，可以控制第一风门20，以使蒸发器14的进风侧与室内空间 22连通，使空气进行内循环。如此，蒸发器14的进风侧与室内空间22连通，同时利用蒸发器14加热冷凝器15，在加快制热速度的同时，进行内循环换气，使得室内空间22的温度更加适宜。
参见图1和图3所示，在一些实施例中，换气控制方法还包括步骤S201和S202。
在步骤S201中，获取室内空间22的空气质量。
在步骤S202中，根据室内空间22的空气质量，控制第一风机29和第二风机30的转速。可以在室内空间22的空气质量较差时，控制第一风机29和第二风机30快速旋转，以使第一风机29和第二风机30的送风速度更快，使得换气的速度更快。可以在室内空间22的空气质量较好时，使第一风机29和第二风机30的转速降低，在节约能源的同时，可以使用户获得更加舒适的体验。
参见图1和图4所示，在一些实施例中，换气控制方法还包括步骤S301和S302。
在步骤S301中，响应于开启换气模式的指令，获取室内空间22的空气质量。用户可以通过选择换气模式或语音输入换气模式的方式，下达开启换气模式的指令。可以响应于开启换气模式的指令，获取室内空间22的空气质量。
在步骤S302中，根据室内空间22的空气质量，确定是否开启换气模式。若当前室内空间22的空气质量等级高于二级，则控制热管理系统10切换至换气模式。若当前室内空间22的空气质量等级低于或等于二级，则生成表示当前室内空间22的空气质量优良的提示信号。可以根据室内空间22的空气质量，确定换气模式的开启。可以在空气质量等级高于二级的情况下，切换至换气模式。可以在空气质量等级低于或等于二级的情况下，获得表示当前室内空间22的空气质量优良的提示信号，而不开启换气模式，从而可以节约能源。同时，在当前室内空间22的空气质量等级高于二级，控制热管理系统10切换至换气模式之后，若室内空间22的空气质量等级达到二级，则退出换气模式。
