参照图1至图5，来对本发明的车载顶置式空调器及其控制方法进行介绍。其中，图1是本发明车载顶置式空调器的控制方法的主要步骤图，图2是本发明车载顶置式空调器的控制方法的一种具体步骤图，图3是本发明一种实施例的车载顶置式空调器的俯视示意图一(出风口 完全打开状态)，图4是本发明一种实施例的车载顶置式空调器的俯视示意图二(出风口部分打开状态)，图5是本发明一种实施例的车载顶置式空调器的控制方法的具体步骤图。
基于背景技术提到的车载顶置式空调器的顶部出风口的气流流量在车辆行驶过程中与室外换热器的换热量不匹配的问题，本发明提供了一种车载顶置式空调器及其控制方法。车载顶置式空调器安装于车辆，车载顶置式空调器的顶部设置有与室外换热器对应的出风口，出风口处设置有开度调节装置，车载顶置式空调器的顶部设置有气体流速传感器，车载顶置式空调器包括控制器，控制器与开度调节装置和气体流速传感器连接。
本领域技术人员可以理解的是，控制器与开度调节装置和气体流速传感器连接，可以采用通信线路进行有线连接，也可以采用蓝牙、WIFI等无线方式连接。开度调节装置可以是设置在出风口处能够以枢转方式、平移方式或者其他合适的方式移动风门从而改变出风口的开度的装置。
如图1所示，本发明的车载顶置式空调器的控制方法主要包括以下步骤：
步骤S100、获取车辆顶置式空调器的顶部当前气流的流速。
在车辆行驶过程中车载顶置式空调器的顶部设置的气体流速传感器实时检测车载顶置式空调器的顶部当前气流的流速并将当前气流的流速发送至控制器。
步骤S200、根据当前气流的流速控制开度调节装置调节出风口的开度，其中出风口的开度被控制成与当前气流的流速负相关。
国内规定高速限速120km/h，在日常驾驶过程中车辆的移动速度通常在0～120km/h，在车辆行驶过程中车载顶置式空调器的顶部流过的气流速度也大致在0～120km/h。可以将0～120km/h的速度范围划定成n个流速区间，出风口的开度预设成与n个流速区间一一对应的n个开度。例如，划定成5个流速区间，分别是[0、20)km/h、[20、45)km/h、[45、70)km/h、[70、95)km/h、[95、120]km/h，出风口的开度预设成与流速区间一一对应的1、4/5、3/5、2/5、1/5。需要说明的是，开度为出风口打开的截面积与其横截面积的比值。控制器接收到气体流速传感器传来的 车载顶置式空调器顶部当前气流的流速时，判断当前气流的流速落入的流速区间，从而确定出出风口的目标开度。例如，车载顶置式空调器的顶部当前气流的流速为32km/h，落入[20、45)km/h的流速区间，相对应的出风口开度为4/5，控制器可以确定当前出风口的目标开度为4/5，从而控制开度调节装置使出风口的开度达到4/5。可以理解的是，车载顶置式空调器的顶部流过的气流速度的范围也可以通过实验测得。
根据车载顶置式空调器的顶部当前气流的流速控制开度调节装置调节出风口的开度，在车辆处于不同行驶状态时使出风口处于对应的开度，从而降低车辆行驶过程中车载顶置式空调器与空气相对运动产生的气流对出风口气流流量的影响，即降低车辆行驶过程中车载顶置式空调器的上方形成的负压区对出风口出风的促进作用，使出风口的气流流量与室外换热器的换热量相匹配，保证压缩机规律地启停，使冷媒回路中管路压力保持相对稳定，从而延长压缩机和冷媒循环管路的使用寿命。
本领域技术人员可以理解的是，流速区间和出风口的开度的数量为5个仅是一种具体的设置方式，本领域技术人员可以根据需要对其作出调整，如流速区间和出风口的开度的数量可以是3个、4个、6个或者更多个等。将速度范围0～120km/h划分成多个流速区间也是一种具体的设置方式，本领域技术人员可以根据实际情况对其作出调整，如速度范围可以是0～100km/h、0～130km/h或者0～140km/h等。
参照图2，在另一种具体的实施方式中，步骤S200包括：
步骤S210、根据当前气流的流速按照公式K＝(ω*V-v)/(ω*V)计算出风口的目标开度，其中K为目标开度，V为车辆能够达到的最大移动速度，0＜ω＜1，v为当前气流的流速。可以理解的是，车辆能够达到的最大移动速度可以是车辆自身设计能够到达的最大移动速度，也可以是车辆在道路上行驶过程中被限制行驶的最高速度。由于车辆行驶过程中，车载顶置式空调器顶部上方的空气与车载顶置式空调器之间存在摩擦，因此气流的速度小于车辆的行驶速度。并且，车载顶置式空调器顶部材料及其表面的粗造度等对摩擦系数有一定的影响，在车辆处于相同行驶速度的情况下不同的车载顶置式空调器顶部的气流的流速也会不同，按照公式K＝(ω*V-v)/(ω*V)计算出风口的目标开度，可以根据具体 的车载顶置式空调器预先设置ω的值，从而能够得到与当前气流的流速更加匹配的出风口的目标开度。
步骤S220、将出风口的开度调节成目标开度。
按照公式K＝(ω*V-v)/(ω*V)计算出风口的目标开度，能够在车辆行驶的任一速度情况下均能够使出风口的开度调节到与该行驶速度状态下匹配的出风口开度，更加有效地降低车辆行驶过程中产生的相对气流对出风口气流的流量的影响，使流经室外换热器的气流流量更加稳定，保证压缩机规律地启停，使冷媒回路中管路压力保持相对稳定，延长压缩机和冷媒循环管路的使用寿命。
对于部分车载顶置式空调器，其外循环风道的进风口也设置在顶部，在车辆行驶过程中产生的相对气流对进风口的气体流量产生影响而与室外换热器的换热量不匹配。
继续参照图2，车载顶置式空调器的控制方法还包括“根据当前气流的流速增大进风口的风机的转速，其中，进风口的风机的转速增大量被控制成与当前气流的流速正相关”的步骤。具体地，包括以下步骤：
步骤S310、根据当前气流的流速按照公式M＝v*ΔM/V计算进风口的风机的转速增大量，其中M为转速增大量，v为当前气流的流速，V为车辆能够达到的最大移动速度，ΔM为预设转速增大量。
预设转速增大量ΔM是预先设置好的，例如，预设转速增大量ΔM可以是20转/分钟、30转/分钟或者其他合适的转速增大量等。
步骤S320、将进风口的风机的转速增加所述转速增大量。
通过这样的设置，根据当前气流的流速按照公式M＝v*ΔM/V计算进风口的风机的转速增大量并将进风口的转速增加所述转速增大量，能够对于车辆处于任一速度的状况下使进风口的风机转速增大对应的转速增大量，从而降低车辆行驶过程中产生的相对气流对车载空调器顶部进风口的气流流动的阻碍作用，使出风口的气流流量与室外换热器的换热量相匹配，保证压缩机规律地启停，使冷媒回路中管路压力保持相对稳定，从而延长压缩机和冷媒循环管路的使用寿命。
在另外一种可行的实施方式中，将车载顶置式空调器的顶部流过的气流的流速范围划定成n个流速区间，进风口的风机设置n个与n个流速区间一一对应的转速增大量。例如，将0～120km/h的速度范围划 定成5个流速区间，分别是(0、20]km/h、(20、45]km/h、(45、70]km/h、(70、95]km/h、(95、120]km/h，进风口的风机的转速增加量设置成与流速区间一一对应的10转/分钟、20转/分钟、30转/分钟、40转/分钟、50转/分钟。控制器接收到气体流速传感器传来的车载顶置式空调器的顶部当前气流的流速时，判断车载顶置式空调器的顶部当前气流的流速落入的流速区间，从而确定出进风口的风机的转速增大量。例如，车载顶置式空调器的顶部当前气流的流速为75km/h，落入(70、95]km/h的流速区间，相对应的进风口的风机的转速增大量为40转/分钟，控制器可以确定当前进风口的风机的转速增大量为40转/分钟，从而控制进风口的风机的转速增加40转/分钟。
对于部分车载顶置式空调器，其顶部设置有多个出风口，多个出风口为沿车辆从前向后方向依次排列的第一出风口、…、第i出风口、…、第p出风口，p为大于等于2的正整数。车载顶置式空调器的控制方法的步骤S200包括以下步骤：
根据当前气流的流速确定第一出风口的目标开度，按照公式K i＝K 1+(i-1)ΔK计算第i出风口的目标开度；
将第一出风口的开度、…、第i出风口的开度、…、第p出风口的开度调节成对应的目标开度；
其中，K 1为第一出风口的目标开度，K i为第i出风口的目标开度，i为大于等于2且小于等于p的正整数，ΔK为预设开度差值。可以理解的是，预设开度差值ΔK可以是1/10、2/10、3/10或者其他值等。
通过这样的设置，能够对于沿前后方向的出风口的开度进行区别设置，从而对于前后方向设置的情况下相对气流对于前后方向设置的出风口的气流流量的影响不同而更加精确地控制前后方向设置的出风口的开度，从而使不同出风口的气体流量与室外换热器对应的部位的换热量相匹配。
下面参照图3至图5并结合顶部具有两个沿前后方向设置的出风口的车载顶置式空调器来进行介绍。
如图3至图5所示并参照图3所示的方位，车载顶置式空调器包括壳体1，壳体1的顶板11上从上向下分布有第一出风口131和第二出风口132，壳体1的下侧(车载顶置式空调器安装至车辆时该侧朝向 车辆尾部)的侧板12上设置有进风口14。顶板11上分别位于第一出风口131和第二出风口132左侧的位置设置有第一开度调节装置和第二开度调节装置，第一开度调节装置和第二开度调节装置分别用于调节第一出风口131和第二出风口132的开度。第一开度调节装置包括第一直线电机21以及与第一直线电机21的输出轴连接的第一风板22。第二开度调节装置包括第二直线电机31以及与第二直线电机31的输出轴连接的第二风板32。
车载顶置式空调器的控制方法包括以下步骤：
步骤S100、获取车载顶置式空调器的顶部当前气流的流速。
步骤S211、按照公式K 1＝(ω*V-v)/(ω*V)计算第一出风口的目标开度K 1，按照公式K 2＝K 1+ΔK计算第二出风口的目标开度K 2。其中，V为车辆能够达到的最大移动速度，v为当前气流的流速，ΔK为预设开度差值，0＜ω＜1，如ω可以预设成0.8。步骤S221、将第一出风口的开度和第二出风口的开度调节成对应的目标开度。
例如，车辆能够达到的最大移动速度120km/h，预设开度差值为1/10，ω＝0.8。当检测到车辆当前的移动速度为60km/h时，K 1＝(0.8×120-60)/(0.8×120)＝0.375，K 2＝0.375+1/10＝0.475。控制器控制第一直线电机21和第二直线电机22分别驱动第一风板22和第二风板32分别移动至对应的位置而使第一出风口131的开度和第二出风口132的开度达到0.375和0.475。
本领域技术人员可以理解的是，也可以将车载顶置式空调器的顶部流过的气流的流速范围划定成n个流速区间，出风口的开度设置成包括与车辆的n个流速区间一一对应的n个开度，判断车载顶置式空调器的顶部当前气流的流速所处的流速区间并确定第一出风口的目标开度K 1，按照公式K i＝K 1+(i-1)ΔK计算第i出风口的目标开度。
在另外一种实施方式中，车载顶置式空调器的顶部设置有沿车辆从前向后方向依次排列的第一进风口、…、第j进风口、…、第q进风口，q为大于等于2的正整数。“根据当前气流的流速增大进风口的风机的转速，其中，进风口的风机的转速增大量被控制成与当前气流的流速正相关”的步骤包括：
根据当前气体的流速确定第一进风口的风机的转速增大量；
按照公式M j＝M 1-(j-1)Δm计算第j进风口的风机的转速增大量；
将第一进风口的风机的转速、…、第j进风口的风机的转速、…、第q进风口的风机的转速增加对应的转速增大量；
其中，M 1为第一进风口的风机的转速增大量，M j为第j进风口的风机的转速增大量，q为大于等于2的正整数，j为大于等于2且小于等于q的正整数，Δm为预设转速增大差。
可以理解的是，可以按照公式M＝v*ΔM/V计算第一进风口的风机的转速增大量，也可以将车载顶置式空调器的顶部流过的气流的流速范围划定成n个流速区间，进风口的风机设置n个与n个流速区间一一对应的转速增大量，判断车载顶置式空调器的顶部当前气流的流速所处的流速区间并确定第一进风口的风机的转速增大量。
通过这样设置，能够对于沿前后方向的进风口的转速进行区别设置，从而对于前后方向设置的情况下相对气流对于前后方向设置的进风口的气流流量的影响不同而更加精确地控制前后方向设置的进风口的风机的转速，从而使不同进风口的气体流量与室外换热器对应的部位的换热量相匹配。

此外，本发明还提供了一种车辆，车辆包括上述实施例的车载顶置式空调器。
通过以上描述可以看出，在本发明的技术方案中，根据车载顶置式空调器的顶部当前气流的流速控制开度调节装置调节出风口的开度，能够在车辆处于不同速度行驶的状态下使出风口处于对应的开度，使出风口的气流流量与室外换热器的换热量相匹配，保证压缩机规律地启停，使冷媒回路中管路压力保持相对稳定，从而延长压缩机和冷媒循环管 路的使用寿命。另外，无需对车辆进行改造以便控制器与车辆建立通信连接，使用本发明的控制方法的车载顶置式空调器可以适用于任何车辆，安装和使用更加方便。
