Abstract

Embodiments of the present disclosure relate to a vapor compression system that includes a refrigerant loop, a compressor disposed along the refrigerant loop and configured to circulate refrigerant through the refrigerant loop, a condenser disposed downstream of the compressor along the refrigerant loop and configured to condense vapor refrigerant to liquid refrigerant, a subcooler coupled to the condenser, where the subcooler is external of a shell of the condenser, and where the subcooler is configured to receive the liquid refrigerant from the condenser and to cool the liquid refrigerant to subcooled refrigerant, and an evaporator disposed downstream of the subcooler along the refrigerant loop and configured to evaporate the subcooled refrigerant to the vapor refrigerant.
