クルにおいて、２台の蒸発器の内蒸発器６ａを強風。Conventional structure and its problems In general, the refrigeration cycle of an air conditioner consists of a compressor 1, an indoor heat exchanger 2, a pressure reducer 3, a liquid tank 4, an outdoor heat exchanger (evaporation In addition, in order to increase the evaporation capacity, the outdoor heat exchanger, that is, the evaporator 5, is constructed of a plurality of evaporators 6a, sb.
The high-pressure liquid refrigerant is divided by a flow divider 6. However, each evaporator 6a of the branch 6
, Since there is a height difference between the connection parts ea and eb to sb, this causes a pressure difference due to the vertical drift of the refrigerant and worsens the divided flow condition. Due to the deviation in evaporator efficiency that occurs, an evaporator with a high proportion of gas refrigerant with a large specific volume will have a larger pressure loss, which will further worsen the shunt flow.
There was a problem in that the refrigerant could not be distributed evenly to the evaporator. In addition, in a refrigerant cycle configured with two independent evaporators, strong wind blows through the evaporator 6a of the two evaporators.

の差異による分流偏差が大きいという事例も報告されて
いる。When the evaporator 6b is operated with a light breeze, the evaporator 6a has a larger evaporation capacity, so the refrigerant becomes a gaseous refrigerant with a large specific volume in the evaporator 5b. However, the pressure P6. Since P7 is common regardless of the difference in capacity, the pressure loss ΔP of the evaporators 5a and 5b is
Since the flow is divided so that 5a+Δ"sb is mutually equal, the divided refrigerant in the evaporator 5a has a problem that the flow rate of the refrigerant is lower than that in the evaporator 5b, causing deterioration of the divided flow condition. It has also been reported that the shunt 6 has a large deviation in shunt flow due to differences in its installation method.

Note that the refrigerant distribution tube 10 may be a capillary tube, as long as it communicates between the inlets of the heat exchanger.
