A refrigeration circuit for a vehicle system includes a compressor, an evaporator, an accumulator, an inlet tube, an outlet tube, and a bypass valve. The inlet tube is configured to deliver refrigerant from the evaporator to the accumulator. The outlet tube is configured to deliver refrigerant from the accumulator to the compressor. The bypass valve is in fluid communication with the inlet and outlet tubes. The bypass valve has an open position and a closed position. The bypass valve is configured to direct refrigerant flow from the inlet tube to the outlet tube to bypass the accumulator when in the open position. The bypass valve is configured to restrict refrigerant from flowing from the inlet tube to the outlet tube when in the closed position.
