Abstract
An embodiment refrigerant module of an integrated thermal management system for a vehicle is configured such that a refrigerant circulates sequentially through a compressor, a condenser, a heat exchanger, an expansion valve, an evaporator, and a vapor-liquid separator. The heat exchanger and the expansion valve are disposed below at least one of the condenser and the evaporator, thereby performing heat exchange between the refrigerant discharged from the condenser and the refrigerant discharged from the vapor-liquid separator.
Claims14
A refrigerant module for an integrated thermal management system for a vehicle, the refrigerant module comprising:
- a compressor comprising a first refrigerant intake port through which a refrigerant is drawn and a first refrigerant discharge port through which the refrigerant is discharged after being compressed;
- a condenser comprising a second refrigerant intake port through which the refrigerant discharged from the compressor is drawn and a second refrigerant discharge port through which the refrigerant is discharged after being heat-exchanged;
- an expansion valve comprising a third refrigerant intake port through which the refrigerant discharged from the condenser is drawn and a third refrigerant discharge port through which the refrigerant is discharged after being expanded;
- an evaporator comprising a fourth refrigerant intake port through which the refrigerant discharged from the expansion valve and a fourth refrigerant discharge port through which the refrigerant is discharged after being heat-exchanged;
- a vapor-liquid separator comprising a fifth refrigerant intake port through which the refrigerant discharged from the evaporator is drawn and a fifth refrigerant discharge port through which a liquid refrigerant and a vapor refrigerant separated from the refrigerant are discharged;
- and
- a heat exchanger configured to perform a heat exchange between the refrigerant discharged from the condenser and drawn into the expansion valve and the refrigerant discharged from the vapor-liquid separator and drawn into the compressor;
- wherein the heat exchanger and the expansion valve are disposed below the condenser and the evaporator;
- wherein a first inlet of a first flow path provided in the heat exchanger is disposed directly below the second refrigerant discharge port provided in the condenser;
- wherein the third refrigerant intake port of the expansion valve is disposed directly above a first outlet of the first flow path provided in the heat exchanger;
- and
- wherein the second refrigerant discharge port of the condenser and the third refrigerant intake port of the expansion valve are indirectly connected through the first flow path of the heat exchanger such that the refrigerant discharged from the condenser passes through the first flow path of the heat exchanger and then draws into the expansion valve.
