Air Conditioner Units Having Dehumidification Features
Air conditioner units are provided. An air conditioner unit includes an outdoor heat exchanger, the outdoor heat exchanger including a coil assembly through which refrigerant is flowable, and an indoor heat exchanger, the indoor heat exchanger comprising a coil assembly through which refrigerant is flowable. The air conditioner unit further includes an auxiliary heat exchanger disposed between the outdoor heat exchanger and the indoor heat exchanger along a refrigerant flow path, the auxiliary heat exchanger including a coil assembly through which refrigerant is flowable and further including a phase change material. The air conditioner unit further includes a compressor in fluid communication with the outdoor heat exchanger, the indoor heat exchanger and the auxiliary heat exchanger, and a bulkhead disposed between the outdoor heat exchanger and the indoor heat exchanger along a transverse direction, the bulkhead defining the indoor portion and the outdoor portion.
