空调器除霜的方法和装置
摘要：
本发明公开了一种空调器除霜的方法和装置，该方法包括：在空调器压缩机连续运行的时间超过预定的时间段，且室内盘管温度持续下降之后，确定室内盘管温度和空调器当前的风速级别；当室内盘管温度低于室内机当前的风速级别对应的预设温度值时，空调器进入除霜状态。本发明通过在空调器压缩机连续运行的时间超过预定的时间段，且室内盘管温度持续下降之后，确定室内盘管温度和空调器当前的风速级别；当室内盘管温度低于室内机当前的风速级别对应的预设温度值时，空调器进入除霜状态，能够针对室内机不同风速的情况下，合理的安排除霜进入的时间，提高系统除霜的准确性。
摘要（英）：

The invention discloses a defrosting method and a defrosting device for an air conditioner. The defrosting method includes determining the temperature of an indoor coiled tube and a current wind speed level of the air conditioner after the continuous running time a compressor of the air conditioner exceeds a preset time period and the temperature of the indoor coiled tube continuously drops; enabling the air conditioner to be in a defrosting state when the temperature of the indoor coiled tube is lower than a preset temperature value corresponding to the current wind speed level of an indoor unit. The defrosting method and the defrosting device have the advantages that the temperature of the indoor coiled tube and the current wind speed level of the air conditioner are determined after the continuous running time of the compressor of the air conditioner exceeds the preset time period and the temperature of the indoor coiled tube continuously drops, and the air conditioner is in the defrosting state when the temperature of the indoor coiled tube is lower than the preset temperature value corresponding to the current wind speed level of the indoor unit, so that defrosting actuating moments can be reasonably arranged according to different wind speed conditions of the indoor unit, and the defrosting accuracy of a system can be improved.
