PROBLEM TO BE SOLVED: To provide a heat exchange system capable of surely suppressing local frosting near an inlet of a heat source-side heat exchanger functioned as an evaporator in a heating cycle, and performing a stable operation.SOLUTION: In a heat exchange system 1 which includes a refrigeration cycle 8 composed of a compressor 2, a use-side heat exchanger 4, an expansion valve 5, a heat source-side heat exchanger 6 and the like, and in which a non-azeotropic refrigerant mixture having temperature glide is filled in the refrigeration cycle 8, refrigerant circuits 6A, 6B of the heat source-side heat exchanger 6 functioned as an evaporator in a heating cycle, are constituted so that the circuit 6A once placed in the heat exchanger 6 is taken out to the external, and then connected to a plurality of circuits 6B again through capillary tubes 12 for distribution to circulate the refrigerant into the heat exchanger 6. |
