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,车辆和/或车载顶置式空调器设置有用于检测车辆的移动速度的速度传感器,车载顶置式空调器包括控制器,控制器与开度调节装置和速度传感器连接。Based on the problem that the air flow of the top air outlet of the vehicle-mounted overhead air conditioner does not match the heat exchange of the outdoor heat exchanger during the running of the vehicle mentioned in the background art, the present invention provides a vehicle-mounted overhead air conditioner and the same. Control Method. The vehicle-mounted overhead air conditioner is installed on the vehicle, the top of the vehicle-mounted overhead air conditioner is provided with an air outlet corresponding to the outdoor heat exchanger, and the air outlet is provided with an opening adjustment device, and the vehicle and/or the vehicle-mounted overhead air conditioner is provided with a A speed sensor for detecting the moving speed of the vehicle, the vehicle-mounted overhead air conditioner includes a controller, and the controller is connected with the opening adjustment device and the speed sensor.
本领域技术人员可以理解的是,速度传感器可以是车辆的仪表盘内部安装有将检测变速箱输出轴转速并转化成车辆移动速度的速度传感器,或者车载顶置式空调器上设置有基于实时定位信息测算其移动速度的速度传感器,也可以包括同时设置在车辆和车载顶置式空调器上的两个速度传感器。在包括同时设置在车辆和车载顶置式空调器上的两个速度传感器的情形下,控制器可以根据二者测得到车辆移动速度来求平均值作为车辆移动的速度,尽量减小测量误差,并且在其中一个速度传感器出现故障无法工作的情况下,控制器依然可以根据另一个速度传感器来获取车辆的移动速度。另外,控制器与开度调节装置和速度传感器连接,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。It can be understood by those skilled in the art that the speed sensor may be a speed sensor installed inside the instrument panel of the vehicle that will detect the speed of the output shaft of the gearbox and convert it into the moving speed of the vehicle, or a vehicle overhead air conditioner with real-time positioning information based on The speed sensor for measuring its moving speed may also include two speed sensors installed on the vehicle and the vehicle-mounted overhead air conditioner at the same time. In the case of including two speed sensors installed on the vehicle and the vehicle overhead air conditioner at the same time, the controller can obtain an average value of the vehicle moving speed according to the two measured vehicle moving speeds as the vehicle moving speed, so as to reduce the measurement error as much as possible, and In the case that one of the speed sensors fails and cannot work, the controller can still obtain the moving speed of the vehicle according to the other speed sensor. In addition, the controller is connected with the opening adjustment device and the speed sensor, and can be connected by a wired connection through a communication line, or by a wireless connection such as Bluetooth and WIFI. The opening degree adjusting device may be a device disposed at the air outlet, which can move the damper in a pivoting manner, a translation manner or other suitable manners, thereby changing the opening degree of the air outlet.
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:As shown in Figure 1, the control method of the vehicle-mounted overhead air conditioner of the present invention mainly comprises the following steps:
步骤S100、获取车辆当前的移动速度。Step S100, obtaining the current moving speed of the vehicle.
速度传感器实时检测车辆当前的移动速度并将车辆当前的移动速度发送至控制器。The speed sensor detects the current moving speed of the vehicle in real time and sends the current moving speed of the vehicle to the controller.
步骤S200、根据车辆当前的移动速度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车辆当前的移动速度负相关。Step S200 , controlling the opening degree adjusting device to adjust the opening degree of the air outlet according to the current moving speed of the vehicle, wherein the opening degree of the air outlet is controlled to be negatively correlated with the current moving speed of the vehicle.
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。可以将0~120km/h的速度范围划定成n个速度区间,出风口的开度预设成与n个速度区间一一对应的n个开度。例如,划定成5个速度区间,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速度区间一一对应的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。控制器接收到速度传感器传来的车辆当前的移动速度时,判断车辆当前的移动速度落入的速度区间,从而确定出出风口的目标开度。例如,车辆当前的移动速度为50km/h,落入[45、70)km/h的速度区间,相对应的出风口开度为3/5,控制器可以确定当前出风口的目标开度为3/5,从而控制开度调节装置使出风口的开度达到3/5。In China, the speed limit of high-speed is 120km/h, and the moving speed of the vehicle during daily driving is usually between 0 and 120km/h. The speed range from 0 to 120 km/h can be divided into n speed intervals, and the opening of the air outlet is preset as n opening degrees corresponding to the n speed intervals. For example, it is divided into 5 speed intervals, which are (0, 20) km/h, [20, 45) km/h, [45, 70) km/h, [70, 95) km/h, [95 , 120] km/h, the opening of the air outlet is preset to 1, 4/5, 3/5, 2/5, 1/5 corresponding to the speed interval. It should be noted that the opening is the ratio of the open cross-sectional area of the air outlet to its cross-sectional area. When the controller receives the current moving speed of the vehicle from the speed sensor, it determines the speed range that the current moving speed of the vehicle falls into, so as to determine the target opening of the air outlet. For example, the current moving speed of the vehicle is 50km/h, which falls into the speed range of [45, 70)km/h, and the corresponding air outlet opening is 3/5. The controller can determine the target opening of the current air outlet as 3/5, thereby controlling the opening adjustment device to make the opening of the air outlet reach 3/5.
根据车辆当前的速度控制开度调节装置调节出风口的开度,在车辆处于不同移动速度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。According to the current speed of the vehicle, the opening adjustment device adjusts the opening of the air outlet, so that the air outlet is at the corresponding opening when the vehicle is at different moving speeds, thereby reducing the relative movement of the vehicle-mounted overhead air conditioner and the air during the driving process. The influence of airflow on the airflow at the air outlet, that is, reducing the promotion effect of the negative pressure area formed above the vehicle overhead air conditioner on the air outlet during the driving process of the vehicle, so that the air flow at the air outlet can be exchanged with the heat exchange of the outdoor heat exchanger. It can ensure that the compressor starts and stops regularly, so that the pipeline pressure in the refrigerant circuit remains relatively stable, thereby prolonging the service life of the compressor and the refrigerant circulation pipeline.
本领域技术人员可以理解的是,速度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,如速度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划分成多个速度区间也是一种具体的设置方式,本领域技术人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。It can be understood by those skilled in the art that the number of the speed intervals and the openings of the air outlet is only a specific setting method, and those skilled in the art can adjust them as needed, such as the speed interval and the air outlet opening. The number of openings may be 3, 4, 6 or more, etc. Dividing the speed range from 0 to 120km/h into multiple speed intervals is also a specific setting method, and those skilled in the art can adjust it according to the actual situation. For example, the speed range can be 0 to 100km/h, 0 to 130km /h or 0 to 140km/h, etc.
参照图2,在另一种具体的实施方式中,步骤S200包括:2, in another specific implementation, step S200 includes:
步骤S210、根据车辆当前的移动速度按照公式K=(V-v)/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,v为车辆当前的移动速度。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。Step S210: Calculate the target opening of the air outlet according to the formula K=(V-v)/V according to the current moving speed of the vehicle, where K is the target opening, V is the maximum moving speed that the vehicle can reach, and v is the current moving speed of the vehicle . It can be understood that the maximum moving speed that the vehicle can reach may be the maximum moving speed that the vehicle itself is designed to reach, or the maximum speed that the vehicle is restricted to travel while traveling on the road.
步骤S220、将出风口的开度调节成目标开度。Step S220, adjusting the opening of the air outlet to the target opening.
按照公式K=(V-v)/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速度匹配的开度,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。According to the formula K=(V-v)/V, the target opening of the air outlet can be calculated, and the opening of the air outlet can be adjusted to the opening degree matching the speed at any speed of the vehicle, which can reduce the speed of the vehicle more effectively. The influence of the relative airflow generated during driving on the airflow at the air outlet makes the airflow through the outdoor heat exchanger more stable, ensures that the compressor starts and stops regularly, keeps the pipeline pressure in the refrigerant circuit relatively stable, and prolongs compression. The service life of the machine and the refrigerant circulation line.
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。For some vehicle-mounted overhead air conditioners, the air inlet of the external circulation air duct is also set at the top, and the relative airflow generated during the driving of the vehicle affects the gas flow of the air inlet and does not match the heat exchange of the outdoor heat exchanger. .
继续参照图2,车载顶置式空调器的控制方法还包括“根据车辆当前的移动速度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车辆当前的移动速度正相关”的步骤。具体地,包括以下步骤:Continuing to refer to FIG. 2 , the control method of the vehicle-mounted overhead air conditioner further includes “increasing the rotational speed of the fan at the air inlet according to the current moving speed of the vehicle, wherein the increase in the rotational speed of the fan at the air inlet is controlled to be consistent with the current moving speed of the vehicle. positive correlation" steps. Specifically, it includes the following steps:
步骤S310、根据车辆当前的移动速度按照公式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为车辆能够达到的最大移动速度,ΔM为预设转速增大量。Step S310: Calculate the rotational speed increase of the fan at the air inlet according to the formula M=v*ΔM/V according to the current moving speed of the vehicle, where M is the rotational speed increase, v is the maximum moving speed that the vehicle can reach, and ΔM is the preset rotational speed Increase the amount.
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。The preset rotational speed increase amount ΔM is preset, for example, the preset rotational speed increase amount ΔM may be 20 rpm, 30 rpm, or other suitable rotational speed increases.
步骤S320、将进风口的风机的转速增加所述转速增大量。Step S320 , increasing the rotational speed of the fan at the air inlet by the rotational speed increase amount.
通过这样的设置,根据车辆行驶的速度按照公式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,能够对于任一速度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。With this setting, the rotational speed increase of the fan at the air inlet is calculated according to the formula M=v*ΔM/V according to the speed of the vehicle, and the rotational speed of the air inlet is increased by the rotational speed increase, so that the air intake can be increased for any speed condition. The increase in the rotational speed of the fan at the air outlet corresponds to the increase in rotational speed, thereby reducing the obstruction of the relative airflow generated during vehicle driving on the air flow at the air inlet at the top of the vehicle air conditioner, so that the air flow at the air outlet is compatible with the heat exchange of the outdoor heat exchanger. It can ensure that the compressor starts and stops regularly, so that the pipeline pressure in the refrigerant circuit remains relatively stable, thereby prolonging the service life of the compressor and the refrigerant circulation pipeline.
在另外一种可行的实施方式中,将车辆的移动速度范围划定成n个速度区间,进风口的风机设置n个与n个速度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个速度区间,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速度区间一一对应的10 转/分钟、20转/分钟、30转/分钟、40转/分钟、50转/分钟。控制器接收到速度传感器传来的车辆当前的移动速度时,判断车辆当前的移动速度落入的速度区间,从而确定出进风口的风机的转速增大量。例如,车辆当前的移动速度为75km/h,落入(70、95]km/h的速度区间,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。In another feasible implementation manner, the moving speed range of the vehicle is delineated into n speed intervals, and the fan at the air inlet is set with n rotational speed increases corresponding to the n speed intervals one-to-one. For example, the speed range from 0 to 120km/h is divided into 5 speed intervals, which are (0, 20] km/h, (20, 45] km/h, (45, 70] km/h, (70 , 95]km/h, (95, 120]km/h, the speed increase of the fan at the air inlet is set to 10 rpm, 20 rpm, 30 rpm, 40 rpm corresponding to the speed interval one-to-one. /min, 50 rpm. When the controller receives the current moving speed of the vehicle from the speed sensor, it determines the speed range that the current moving speed of the vehicle falls into, so as to determine the rotational speed increase of the fan at the air inlet and outlet. For example, The current moving speed of the vehicle is 75km/h, which falls within the speed range of (70, 95]km/h. The corresponding increase in the rotational speed of the fan at the air inlet is 40 rpm. The controller can determine the current fan at the air inlet. The speed increase of 40 rpm, so that the speed of the fan that controls the air inlet is increased by 40 rpm.
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:For some vehicle-mounted overhead air conditioners, a plurality of air outlets are arranged on the top of the air conditioner, and the plurality of air outlets are the first air outlet, ..., the i-th air outlet, ..., the p-th air outlet arranged in sequence from the front to the rear of the vehicle, p is a positive integer greater than or equal to 2. Step S200 of the control method for the vehicle-mounted overhead air conditioner includes the following steps:

i=K
1+(i-1)ΔK计算第i出风口的目标开度;
Determine the target opening of the first air outlet according to the current moving speed of the vehicle, and calculate the target opening of the i-th air outlet according to the formula K i =K 1 +(i-1)ΔK;
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;Adjust the opening degree of the first air outlet, ..., the opening degree of the i-th air outlet, ..., the opening degree of the p-th air outlet to the corresponding target opening degree;
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、3/10或者其他值等。
Wherein, K 1 is the target opening degree of the first air outlet, K i is the target opening degree of the ith air outlet, i is a positive integer greater than or equal to 2 and less than or equal to p, and ΔK is the preset opening degree difference. It can be understood that, the preset opening degree difference ΔK may be 1/10, 3/10, or other values.
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。With this arrangement, the openings of the air outlets along the front-rear direction can be set differently, so that in the case of being arranged in the front-rear direction, the influence of the relative airflow on the air flow of the air outlets arranged in the front-rear direction is different, and the front-rear direction can be controlled more accurately. The opening of the air outlet is set so that the gas flow of different air outlets matches the heat exchange of the corresponding part of the outdoor heat exchanger.

1=(120-60)/120=1/2,K

For example, the maximum moving speed that the vehicle can reach is 120km/h, and the preset opening difference is 1/12. When it is detected that the current moving speed of the vehicle is 60 km/h, K 1 =(120-60)/120=1/2, K 2 =1/2+1/12=7/12. The controller controls the first linear motor 21 and the second linear motor 22 to drive the first air plate 22 and the second air plate 32 to move to corresponding positions respectively, so that the opening of the first air outlet 131 and the second air outlet 132 The opening reaches 1/2 and 7/12.
