1. A refrigerant module of an integrated thermal management system for a vehicle, the refrigerant module comprising:
a compressor having a first suction port into which a refrigerant is suctioned and having a first discharge port through which the refrigerant that is compressed is discharged;
a condenser having a second suction port into which the refrigerant discharged from the compressor is suctioned and having a second discharge port through which the refrigerant that is heat-exchanged is discharged;
an expansion valve having a third suction port into which the refrigerant discharged from the condenser is suctioned and having a third discharge port through which the refrigerant that is expanded is discharged;
an evaporator having a fourth suction port into which the refrigerant discharged from the expansion valve is suctioned and having a fourth discharge port through which the refrigerant that is heat-exchanged is discharged;
an accumulator having a fifth suction port into which the refrigerant discharged from the evaporator is suctioned and having a fifth discharge port through which the refrigerant separated into liquid and gas phases is discharged; and
a connection passage enabling the refrigerant discharged from the accumulator to flow to the compressor;
wherein the refrigerant module is configured such that a refrigerant circulates through the compressor, the condenser, the expansion valve, the evaporator, and the accumulator,
wherein the first discharge port of the compressor is directly connected to the second suction port of the condenser, the second discharge port of the condenser is directly connected to the third suction port of the expansion valve, the third discharge port of the expansion valve is directly connected to the fourth suction port of the evaporator, the fourth discharge port of the evaporator is directly connected to the fifth suction port of the accumulator, and the fifth discharge port of the accumulator is indirectly connected to the first suction port of the compressor by the connection passage; and
wherein the first discharge port is oriented in an upward direction from an upper end portion of the compressor, the second suction port is oriented in a downward direction from a lower end portion of the condenser, and the second suction port of the condenser is disposed directly above the first discharge port of the compressor such that the first discharge port and the second suction port are directly connected to each other and are in communication with each other.
