Abstract

The invention discloses an air conditioner control method and system of an intermittent power supply railway vehicle. An air conditioner is controlled to be in a pre-working mode, a normal working mode and an energy-saving working mode under different conditions; in the pre-working mode, by setting and reaching a new target temperature, energy storage is achieved to the maximum extent during charging so as to maintain a comfort degree of a vehicle during subsequent operation, meanwhile, energy consumption of the air conditioner when the vehicle is not charged is reduced, and a capacity of an energy storage power supply for continuously providing necessary power for traction, braking and other key systems is prolonged; and according to available electric energy and different set thresholds,the air conditioner is in different energy-saving working modes, the necessary power supply capacity of the vehicle is further guaranteed, and meanwhile the comfort degree of passengers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning control for vehicles, and in particular relates to an air-conditioning control method, system and vehicle for rail vehicles with intermittent power supply. Background technique [0002] Traditional rail vehicle air conditioners are powered by AC380V power, which is obtained by inverting DC high-voltage power through static converters. Since traditional rail vehicles are powered by the third rail or catenary, as long as the high-voltage power supply is available, the air conditioner can always work at the rated operating point, and its energy consumption is only related to the external environment (temperature and humidity) and the passenger capacity in the vehicle. Due to environmental and cost considerations, intermittently powered rail vehicles are gaining more and more attention. Intermittent power supply rail vehicles use supercapacitors or batteries to drive vehicles to start in a f...
