PROBLEM TO BE SOLVED: To provide a compact, inexpensive and economic refrigerant heating auxiliary device of a simple configuration, capable of rotating a turbine expanding machine by utilizing fluid power of a refrigerant, generating heat by rotating an eddy current heat generating machine by torque of the turbine expanding machine to surely increase a temperature of the refrigerant by the heat, performing stable defrosting and heating with high efficiency, performing an operation of a refrigerating cycle even in a cold district or at a low temperature, and dispensing with external power, an external heat source and the like as an evaporation heat source in an evaporating process. SOLUTION: This refrigerant heating auxiliary device includes an integrated heat self-balance heat exchanger 8 having a primary side 8a and a secondary side 8b, the turbine expanding machine 9 disposed at an inlet side of the secondary side 8b, and the eddy current heat generating machine 10 rotated by the torque of the turbine expanding machine 9 and disposed at an outlet side of the secondary side 8b, the refrigerant is distributed to a compressor 1 successively through the primary side 8a of the heat self-balance heat exchanger 8, the turbine expanding machine 9, the secondary side 8b and the eddy current heat generating machine 10, and a temperature of the refrigerant is increased by the heat generated by the eddy current heat generating machine 10.
