Abstract (en)
[origin: EP1975525A1] An air conditioner that reverses and appropriately controls the stream of refrigerant between paths of a flow divider corresponding to an air conditioner heat exchanger having a plurality of paths to increase the heat exchange capacity is provided. The air conditioner includes a compressor, a four-way valve, an outdoor heat exchanger, a restriction device, and an indoor heat exchanger including a plurality of paths. These members are sequentially connected by a refrigerant pipe to form a refrigerant circuit. A flow divider including a plurality of paths is arranged between the indoor heat exchanger, which includes the plurality of paths, and the restriction device. A refrigerant flow amount regulation valve is provided for each of the plurality of paths in the flow divider. In a predetermined operation state, more refrigerant is distributed to a predetermined passage in which the processing capacity is large and the refrigerant temperature at an outlet of the indoor heat exchanger is high in comparison with other paths.
