Abstract
Embodiments relate generally to subcooling control of a heating, ventilation, and air conditioning (HVAC) system. An HVAC system may include a compressor, a first heat exchanger, a refrigerant vessel having an inlet fluidly coupled to a discharge conduit extending from the compressor, and the refrigerant vessel having an outlet fluidly coupled to a liquid conduit, the liquid conduit configured to pass liquid refrigerant between the first heat exchanger and a second heat exchanger. The HVAC system may further include an electronic expansion valve (EEV) fluidly coupled between the discharge conduit and the inlet of the refrigerant vessel, wherein the EEV is configured to modulate and divert a portion of vapor refrigerant flowing through the discharge conduit into the refrigerant vessel to control subcooling (SC) produced by the HVAC system.
