Zusammenfassung:An air conditioning system including an evaporator having a manifold and a plurality of tubes extending downward in a vertical direction from the manifold. The evaporator defines at least one PCM tank engaging the manifold for storing a phase change material. When operating in a first operating mode, heat is transferred from the phase change material to the refrigerant to freeze and cool the phase change material. When operating in a second operating mode, heat is transferred from the refrigerant to the frozen phase change material to condense the refrigerant. The condensed refrigerant falls downwardly through the tubes and receives heat from a flow of air to cool the air and evaporate the refrigerant. The evaporated refrigerant rises upwardly back to the low pressure of the cold manifold.
