在本申请实施例中，如图1至图4所示，该空调系统包括第一换热风道10、第二换热风道40以及循环系统，第一换热风道10内置有蒸发器11，且第一换热风道10具有第一进风端12与第一出风端13，第一进风端12连通连通车外的新风入口30，第一出风端13连通连通车内的第一出风口14。第二换热风道40内置有加热器41，且第二换热风道40具有第二进风端42与第二出风端43，第二进风端42连通新风入口30和/或第一进风端12，第二出风端43连通连通车内的第二出风口44。该循环系统包括连通车内的循环风进口20，所述循环风进口20分别连通所述第一进风端12和/或第二进风端42，用于回收经由第一换热风道10和/或第二换热风道40换热后的气体，并将其循环输送至第一进风端12和/或第二进风端42。
在一实施方式中，该空调系统固定于汽车车身，该第一换热风道10内设有蒸发器11，于降温模式下，外部空气经由汽车空气过滤系统过滤后形成的新风，通过新风入口30进入第一换热风道10，经由第一换热风道10冷却的气体由第一出风端13经过，并由第一出风口14排入车内，为车内降温；第二换热风道40内为加热器41，加热器41在第二换热风道40中为气体升温，故而于取暖模式下，外部空气经由汽车空气过滤系统过滤后形成的新风，通过新风入口30进入第二换热风道40，经由第二换热风道40加热后的气体由第二出风端43经过，并由第二出风口44排入车内，为车内升温。
但实际工作过程中，尤其遇到极冷或极热的季节，如寒冷的冬季，室外环境温度很低，因此，第二换热风道40从外界吸入的新风温度也很低，不利于加热器41加热，导致空调系统难以快速升温，升温速率变慢；而在炎热的夏季，室外环境温度很高，因此，空调系统从外界吸入的新风温度也很高，不利于蒸发器11换热，导致空调系统难以快速降温，降温速率较慢。使得车内温度变为舒适温度的时间变长，延长乘客的等待时间，影响用户的乘车体验。故而设置循环系统，该循环系统包括连通车内的循环风进口20，所述循环风进口20分别连通所述第一进风端12和第二进风端42，用于回收经由第一换热风道10和/或第二换热风道40换热后的气体，从而在空调系统刚启动的一段时间内，降低蒸发器11进风温度或提升加热器41进风温度，从而促进空调系统快速进入工作状态。
本实施例中，由于循环风进口20、第一出风口14与第二出风口44均连通于车内，且循环风进口20分别连通所述第一进风端12和/或第二进风端42。即第一进风端12分别连通循环风进口20和新风入口30，第二进风端42分别连通循环风进口20和新风入口30。使得第一出风口14和/或第二出风口44流出的气体，为车内换热后，再次流入循环风进口20，并由循环风进口20再次输送至第一进风端12和/或第二进风端42。
在另一实施例中，循环系统包括第一循环风道50，第一循环风道50连通第一换热风道10，以回收经由第一换热风道10换热后的气体，并将其循环输送至第一进风端12。具体地，该第一循环风道50的进风口连通第一出风端13，第一循环风道50的出风口连通第一进风端12，从而回收经由蒸发器11冷却后的气体进入第一循环风道50，并由第一循环风道50再次循环至第一进风端12，从而降低进入第一换热风道10的气体的温度并辅助蒸发器11换热，促进空调系统快速降温。
在又一实施例中，该循环系统还包括第二循环风道60，第二循环风道60连通第二换热风道40，用于回收经由第二换热风道40换热后的气体，并将其循环输送至第一进风端12或第二进风端42。具体地，该第二循环风道60的进风口连通第二出风端43，第二循环风道60的出风口连通第一进风端12或第二进风端42，从而回收经由加热器41加热后的气体进入第二循环风道60，并由第二循环风道60再次循环至第二换热风道40，提升进入第二换热风道40内的气体的温度，并辅助加热器41加热，促进空调系统快速升温。
相较于仅采用循环风进口20回收第一出风口14和/或第二出风口44流出的气体，另外设置第一循环风道50和第二循环风道60可以加快气体回收效率，进一步加快空调系统的升温速率或降温速率。通过控制第一循环风道50的通断与第二循环风道60的通断，从而适应空调系统不同工作模式或状态的切换。且循环风进口20、新风入口30、第一出风口14、第二出风口44的导通和封堵均可以根据空调系统不同工作模式或状态的切换进行对应的调整。
需要说明的是，本申请中所表示的“连通”，只是表明不同管道之间的连接关系，并不代表其连通状态，具体其是否连通由其对应的控制开关，或者各个风道是否被封堵控制。且本实施例中所表述的第一出风端13所代表的是蒸发器11所在位置之后至第一出风口14之前的一段风道；第一进风端12所代表的是蒸发器11所在位置之前的一段风道。第二出风端43所代表的是加热器41所在位置之后至第二出风口44之前的一段风道；第二进风端42所代表的是加热器41所在位置之前的一段风道。且第二进风端42分别连通循环风进口20、及新风入口30所表示的意思可以为：第二进风端42直接连通循环风进口20和新风入口30，即直接在第二进风端42开设循环风进口20和新风入口30；或者，第二进风端42间接连接于循环风进口20和新风入口30，如第二进风端42通过预设的风道分别连接循环风进口20和新风入口30，本实施例中，第二进风端42通过第一进风端12分别连接循环风进口20和新风入口30。
本申请技术方案通过设置第一换热风道10与第二换热风道40，第一换热风道10内置有蒸发器11，且第一换热风道10具有第一进风端12与第一出风端13，第一进风端12连通连通车外的新风入口30，第一出风端13连通连通车内的第一出风口14。第二换热风道40内置有加热器41，且第二换热风道40具有第二进风端42与第二出风端43，第二进风端42连通新风入口30和/或第一进风端42，第二出风端43连通连通车内的第二出风口44。通过控制新风入口30、第一出风口14、第二出风口44的导通和封堵实现空调系统在采暖模式与降温模式下的正常工作，以及二者的相互切换，保证空调系统的正常工作。
但实际工作过程中，尤其遇到极冷或极热的季节，往往会影响空调系统内的蒸发器11与加热器41的工作，降低二者工作效率。导致空调系统难以快速降温或升温。使得车内温度变为舒适温度的时间变长，延长乘客的等待时间，影响用户的乘车体验。故而设置循环系统，该循环系统包括连通车内的循环风进口20，所述循环风进口20分别连通所述第一进风端12和/或第二进风端42，由于循环风进口20、第一出风口14与第二出风口44均连通于车内，使得第一出风口14和/或第二出风口44流出的气体，为车内换热后，再次流入循环风进口20，并由循环风进口20再次输送至第一进风端12和/或第二进风端42。从而回收经由蒸发器11冷却后的气体进入第一进风端12，从而降低进入第一换热风道10的气体的温度并辅助蒸发器11换热，促进空调系统快速降温；或回收经由加热器41加热后的气体于第二换热风道40，提升进入第二换热风道40内的气体的温度，并辅助加热器41加热，促进空调系统快速升温。从而减少车内温度变为舒适温度所需时间，减少乘客的等待时间，提高用户的乘车体验。

在另一实施例中，也可以分别在第一换热风道10的第一进风端12与第二换热风道40的第二进风端42均设置鼓风机80，从而分别驱动第一换热风道10及第二换热风道40内的气体流动，加快空调系统内的气体流动。
