The invention relates to the technical field of automobile air conditioners, in particular to a motor home air conditioner control method. The invention aims to solve the problem of how to reasonably control the air conditioner operation and power supply mode of the touring car to save the use cost of the touring car. In order to achieve the purpose, the control method comprises the steps that when an air conditioner of the motor home is started, the power generation voltage U1 of a photovoltaic panel is obtained; calculating a first ratio of the generating voltage U1 to the rated voltage Un of the motor home air conditioner; judging a voltage interval in which the first ratio is located; if the first ratio is larger than or equal to a first preset threshold value K1 and smaller than a second preset threshold value K2, the operation frequency f of the compressor and the rotating speed r of the inner fan are determined based on the power generation voltage U1 and the rated voltage Un; and controlling the photovoltaic panel to supply power to the motor home air conditioner, and controlling the compressor to operate according to the operating frequency f and the inner fan to operate according to the rotating speed r. The power supply mode of the motor home air conditioner can be reasonably distributed, and the situation that the user experience is seriously affected due to the fact that the power generation voltage of the photovoltaic panel is insufficient to support full-power operation of the motor home air conditioner is avoided.
本发明涉及汽车空调技术领域,具体涉及一种房车空调的控制方法。本申请旨在解决如何合理控制房车空调运行及供电方式对节约房车使用成本的问题。为此目的,本申请的控制方法包括:在房车空调开机时,获取光伏板的发电电压U1;计算发电电压U1与房车空调的额定电压Un的第一比值;判断第一比值所处的电压区间;如果第一比值大于等于第一预设阈值K1且小于第二预设阈值K2,则基于发电电压U1和额定电压Un确定压缩机的运行频率f和内风机的转速r;控制光伏板为房车空调供电,并控制压缩机按照运行频率f、内风机按照转速r运行。本申请能够合理分配房车空调的供电方式,避免因光伏板的发电电压不足以支撑房车空调全功率运行而严重影响用户使用体验。
