Filed: 2018-11-12
Abstract: To provide an air conditioner capable of enhancing heat exchange efficiency by suppressing variation in heat exchange.SOLUTION: A plate fin lamination type heat exchanger is used for an indoor heat exchanger 5, and annular grooves 28b, 30b are provided around header flow passages between a header flow passage A28 and a header flow passage B30 and refrigerant flow passages 31 in the indoor heat exchanger 5. When the indoor heat exchanger 5 is used as an evaporator, the dryness degree of a refrigerant at a heat exchanger inlet is set to 0.1 or less by a gas liquid separator 4. Due to this configuration, a liquid refrigerant present in a lower part in the header flow passage A28 is approximately uniformly moved upwards in the portions of the annular grooves 28b, 30b around the header flow passages due to capillary phenomenon, is mixed with a gas refrigerant and then is caused to flow to the refrigerant flow passages 31. Therefore, the refrigerant with the approximately uniform dryness degree that exhibits sufficient evaporation capacity is caused to flow in the refrigerant flow passages 31 connected to the header flow passage A28, and thus variation in heat exchange amount in each portion of the refrigerant flow passages can be suppressed so as to attain high heat exchange efficiency.SELECTED DRAWING: Figure 1
