Abstract
Aspects of the disclosure relate to an accumulator bottle having a horizontal flow and a u-tube. The u-tube includes (e.g., horizontal) inlet and outlet sections at a common height to minimize a pressure drop for a vaporized refrigerant that passes through the accumulator. Providing the u-tube in a cuboid accumulator with horizontal flow increases the liquid volume capacity of the accumulator while reducing the pressure drop across the accumulator. The u-shape tube also improves oil mixing with the vaporized refrigerant by including an orifice at or near a bottom of the u-tube and within a portion of the accumulator in which liquid oil and/or refrigerant is stored.
