Title:
RAIL VEHICLE APPLYING INTEGRATED HEAT ENERGY MANAGEMENT TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2024/092918
Kind Code:
A1
Abstract:
A rail vehicle applying integrated heat energy management technology. An oil temperature rises when a transformer (1) operates, hot oil in the transformer (1) is pumped out by means of a pipeline and flows to a cooling unit (5) and heat exchangers (3), a three-way valve (4) is arranged in front of the cooling unit (5) and the heat exchangers (3), and when fresh air in an air conditioning unit (2) is required to be heated, part of the oil in the transformer (1) is guided to the heat exchangers (3) by means of the three-way valve (4), and the other part of the oil flows to the cooling unit (5), so as to cool the oil in the transformer (1), the oil in the transformer (1) is used as a heat medium in the heat exchangers (3), and heat is transferred to a refrigerant, so that the oil in the transformer (1) is cooled and flows back to the transformer (1), and the refrigerant, which is in the heat exchangers (3), absorbs the heat to heat the fresh air, thereby forming a cycle of heating the fresh air. The rail vehicle heats fresh air in an air conditioning system by utilizing heat generated during the working process of a transformer of a traction system of electric multiple units, and integrates the traction system and the air conditioning system into an effective heat energy management system, so as to control and optimize a heat transfer process of the vehicle, thereby reducing waste heat emission, and improving the energy utilization efficiency.
