Title:
METHOD FOR AIR CONDITIONING CONTROL OF HIGH-SPEED ELECTRICAL MULTIPLE UNIT SUITABLE FOR HIGH AND COLD ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2015/139501
Kind Code:
A1
Abstract:
A method for air conditioning control of a high-speed electrical multiple unit (EMU) suitable for a high and cold environment; the controller of an air-conditioning system receives an external temperature sensor signal, and identifies the environment temperature; if the average environment temperature Texternal identified by the external temperature sensor of a vehicle air-conditioning system is lower than a set value Td, then the air-conditioning system is transitioned into a control program of "high and cold environment heating device operation control logic"; and if not, then the air-conditioning system performs a normal automatic control logic; if the change of the temperature Texternal in a period not greater than S1 is not less than △T, then the air-conditioning system enters a program of "high and cold environment low-temperature vehicle maintenance control logic"; and if Texternal is not greater than Tf, then activating the freeze-protection mode of the air-conditioning system.
