Evaporator and integrated accumulator and subcooler for hvac&r system

Abstract

A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a working fluid circuit configured to circulate a working fluid therethrough, an evaporator disposed along the working fluid circuit, where the evaporator is configured to place the working fluid in a heat exchange relationship with a conditioning fluid, and a vessel disposed along the working fluid circuit, where the vessel includes an accumulator section and a subcooling section. The working fluid circuit is configured to direct a first flow of the working fluid from the evaporator to the accumulator section of the vessel, the accumulator section is configured to separate the first flow of working fluid into a vapor working fluid and a liquid working fluid, the vessel is configured to direct the liquid working fluid from the accumulator section to the subcooling section, and the subcooling section of the vessel is configured to place the liquid working fluid in a heat exchange relationship with a second flow of working fluid received via the working fluid circuit.
