The invention provides a defrosting method and system for an external heat exchanger of a heat pump air conditioner and computer equipment, and the method comprises the steps that after the heat pump air conditioner is switched to a heating mode, a signal collection module obtains a state signal of the external heat exchanger every first preset time so that a control module can judge the frosting state of the external heat exchanger, and the frosting state of the external heat exchanger is judged; and the defrosting execution module is controlled to enter a defrosting mode according to a preset defrosting control strategy, so that the defrosting execution module defrosts the external heat exchanger according to at least one control signal in the current defrosting mode. According to the defrosting method for the external heat exchanger of the vehicle heat pump air conditioner, frosting is judged in advance, the battery waste heat is used for defrosting the external heat exchanger of the heat pump air conditioner, the problems that a compressor is in a high-power-consumption working state for a long time and a PTC auxiliary heating system with large energy consumption is used for a long time are solved, and energy consumption is greatly reduced.
本发明提出的一种热泵空调的外换热器的除霜方法、系统及计算机设备,该方法包括:当热泵空调切换至制热模式后,信号采集模块每隔第一预设时间,获取外换热器的状态信号以使控制模块判断外换热器结霜状态,并根据预设化霜控制策略控制化霜执行模块进入化霜模式,以使化霜执行模块根据当前化霜模式下的至少一条控制信号对外换热器进行化霜。本发明提出的车辆热泵空调外换热器除霜方法,通过提前判断结霜,并且利用电池余热为热泵空调的外换热器进行除霜,避免了压缩机长时间处于高功耗的工作状态和长时间使用耗能较大的PTC辅助加热系统的问题,极大地减少了能耗。
