    • An air conditioning and ventilation system for a motorcar has an outdoor air passage for introducing fresh outdoor air into the passenger room and another passage for guiding room air to the atmosphere. The two passages intersect at a point where a heat exchanger is provided for exchanging both of the actual heat and the latent heat of the airs flowing through the two passages. Air heating and cooling units are provided in the outdoor air passage downstream of the heat exchanger. The outdoor air flows first through the heat exchanger in heat exchanging relationship with the room air flowing therethrough outwardly and thus is heated or cooled by the room air, whereby the thermal load on the air heating and cooling units is greatly reduced.
    • 用于汽车的空调和通风系统具有用于将新鲜的室外空气引入乘客室的室外空气通道和用于将室内空气引导到大气的另一通道。 两个通道在提供热交换器的点处相交,用于交换流经两个通道的空气的实际热量和潜热。 在热交换器下游的室外空气通道中设置有空气加热和冷却单元。 室外空气首先通过热交换器与与其流过的室内空气热交换,从而被室内空气加热或冷却,从而大大降低了空气加热和冷却装置的热负荷。
