On the other hand, the load fluid is reversely heated in the condenser 2 and passed through the pipe 3' for load heating. Next, the condensed working medium is depressurized by a pressure reducing device 4, and then led to an evaporator 5, where it is introduced through a tube 6 and is a heat source discharged through a tube 6'. After being heated by the fluid,
It is sucked into the compressor 1 again and the above cycle is repeated. On the other hand, the heat source fluid is reversely cooled in the evaporator 5 and is provided for cooling through the tube 6'.

。As understood from the table, R125 and at least one selected from hydrocarbons having 4 to 5 carbon atoms, particularly n-butane, isobutane, cyclobutane, n-pentane, isopentane, and cyclopentane are essential components. The working medium mixture of the present invention can be greatly improved compared to the case where R125 is used alone, and in particular, a working medium mixture in which the composition of R125 is around 20 mol% is a combination of R125 and isobutane, isobutane, cyclobutane, n - It can be seen that the results are greatly improved compared to when pentane, impentane, and cyclopentane were used alone. Although the hydrocarbons having 4 to 5 carbon atoms, which are one of the components of the working medium mixture of the present invention, have a higher coefficient of performance than R125, they have the drawbacks of low refrigerating capacity per unit volume of the compressor and being flammable. ing. On the other hand, although R125 has the disadvantage of a lower coefficient of performance than hydrocarbons with 4 to 5 carbon atoms, it has the advantage of having a high refrigerating capacity per unit volume of the compressor and being non-flammable. Therefore, it can be seen that by using the working medium mixture of the present invention, each of the disadvantages can be improved and the advantages can be taken advantage of, and it is extremely effective.
