The invention relates to an air conditioner defrosting control method which is applied to air conditioning systems of rail transit, and each air conditioning system comprises two air conditioning units. The method comprises the steps that working modes of the two air conditioning units are obtained; under the condition that any one of the two air conditioning units is in a heating mode and the other air conditioning unit is in a ventilation mode, outdoor coil pipe temperatures of the two air conditioning units are obtained; whether the corresponding air conditioning unit meets the defrosting condition or not is determined based on the outdoor coil pipe temperature; and under the condition that the defrosting condition is met, the air conditioning unit in the ventilation mode is controlled to be switched into the heating mode, the air conditioning unit in the heating mode is controlled to be switched into the ventilation mode, and the frosted condenser is defrosted through the ventilation mode while the indoor temperature of the subway carriage is guaranteed. The problem that in the prior art, an air conditioner needs to be converted into a refrigeration mode during defrosting, and the comfort of passengers is reduced is solved.

    本申请涉及一种空调除霜控制方法,应用于轨道交通的空调系统,每个空调系统包括两个空调机组;该方法包括:获取两个空调机组的工作模式;在两个空调机组中的任一个空调机组处于制热模式,且另一个空调机组处于通风模式的情况下,获取两个空调机组的室外盘管温度;基于该室外盘管温度确定对应的空调机组是否满足除霜条件;在满足除霜条件的情况下,控制处于通风模式的空调机组切换为制热模式,控制处于制热模式的空调机组切换为通风模式,在保证地铁车厢的室内温度的同时通过通风模式对结霜的冷凝器进行除霜,解决相关技术中存在的除霜需要将空调转为制冷模式,降低乘客舒适感的问题。
