The invention is suitable for the technical field of automobile air conditioning systems, and provides an automobile air conditioning system based on liquid ammonia cold energy, which comprises an ammonia engine unit, an air conditioning unit and an air distribution unit, the air distribution unit comprises an air blower, the air blower is connected with a warm air heat exchanger and an evaporator through a flow dividing valve, the warm air heat exchanger is connected with a liquid ammonia evaporation box, air is conveyed out of a vehicle through the liquid ammonia evaporation box, and the warm air heat exchanger is further directly connected with the interior of the vehicle through an air conditioner air channel. And an air channel temperature sensor is further arranged at the air conditioner air channel. According to the system, the cooling capacity of liquid ammonia evaporation is utilized, so that the working requirement of an air conditioner is reduced, and the energy loss of an ammonia engine can be effectively reduced; meanwhile, the temperature of the liquid ammonia evaporation box is maintained through waste heat of the ammonia engine, the situation that the evaporation efficiency is affected by supercooling of the liquid ammonia evaporation box is effectively prevented, stable operation of the ammonia engine is guaranteed, and meanwhile the energy requirement for guaranteeing the temperature of the liquid ammonia evaporation box is lowered.
