A centralized energy (CE) module for a vehicle includes: a base plate; a compressor mounted on the base plate and compressing refrigerant; a condenser mounted on the base plate at a location spaced apart from the compressor and heat-exchanges the compressed refrigerant supplied from the compressor with a coolant which flows into the condenser to condense the refrigerant; an evaporator mounted on the base plate at a location spaced apart from the condenser and evaporating the refrigerant supplied from an expansion valve integrally mounted through heat-exchange with the coolant which flows into the evaporator and supplying the evaporated refrigerant to the compressor; and an accumulator connected with the evaporator through the expansion valve, and supplied only a gas refrigerant among the evaporated refrigerants to the compressor while passing through the evaporator.
