The invention relates to an anti-frosting control method for an air conditioning system of a fuel cell hydrogen-powered automobile. The anti-frosting control method comprises the following steps: S1,setting a threshold parameter and preset air outlet displacement corresponding to an ambient temperature outside the automobile by a vehicle control unit (VCU); S2, controlling the air conditioning system to release cold air according to the preset air outlet displacement determined in the step S1 by the VCU; and S3, according to an evaporator surface temperature of the air conditioning system anda threshold value parameter determined in the step S1, adjusting air outlet displacement of the air conditioning system. According to the anti-frosting control method, the optimal refrigerating capacity can be achieved, the optimal thermal comfort is guaranteed, frosting on the surface of the evaporator is prevented, and the stability of the system is guaranteed.

    本发明涉及一种燃料电池氢能汽车空调系统防结霜的控制方法,包括以下步骤:S1、整车控制单元VCU根据车外的环境温度设置与之对应的阈值参数和预设出风排量;S2、所述整车控制单元VCU控制空调系统按照步骤S1确定好的所述预设出风排量释放冷气;S3、根据所述空调系统的蒸发器表面温度以及步骤S1确定好的所述阈值参数,调节所述空调系统的出风排量。本发明能实现最优的制冷能力、保证最优的热舒适性,防止蒸发器表面结霜,保证系统的稳定性。
