The invention discloses an outdoor heat exchanger defrosting method and device and an automobile. When it is determined that an outdoor heat exchanger needs to be defrosted, a first automobile external environment temperature under the condition that the outdoor heat exchanger is frosted is obtained, and defrosting control strategies are selected from a plurality of defrosting control strategies; and a target defrosting control strategy corresponding to the target temperature interval where the first vehicle external environment temperature is located is selected, the opening degree of an active air inlet grille, the gear of a compressor and the duty ratio of a vehicle-mounted electronic fan are adjusted based on the target defrosting control strategy, and defrosting is conducted on an outdoor heat exchanger. According to the defrosting control method and device, the frosting temperature range of the outdoor heat exchanger is divided into different temperature intervals, the corresponding defrosting control strategy is provided for each temperature interval, and the target defrosting control strategy corresponding to the external environment temperature of the first vehicle is determined; and the opening degree of the active air inlet grille, the gear of the compressor and the duty ratio of the vehicle-mounted electronic fan are correspondingly adjusted, and defrosting of the outdoor heat exchanger is achieved.
本发明公开了一种室外换热器化霜方法、装置及汽车,当确定室外换热器需要进行化霜时,获取室外换热器处于结霜情况下的第一车辆外界环境温度,从多个化霜控制策略中,选取第一车辆外界环境温度所在的目标温度区间对应的目标化霜控制策略,基于目标化霜控制策略,调节主动进气格栅的开合度、压缩机档位和车载电子扇的占空比,对室外换热器进行化霜。本发明将使室外换热器结霜的温度范围划分成不同的温度区间,并针对每个温度区间提供对应的化霜控制策略,通过确定第一车辆外界环境温度对应的目标化霜控制策略,并对应调节主动进气格栅的开合度、压缩机档位和车载电子扇的占空比,实现对室外换热器进行化霜。
