PURPOSE:To economically prevent the leakage of a heating medium caused by the deterioration of the seal performance at the shaft penetrating section of a compressor with an increased degree of freedom in selecting a prime mover by reasonably improving a transmission system from the prime mover to the compressor. CONSTITUTION:A heating medium is injected into a thin film case 19, and the passive rotating body 16 of a compressor 2 or the whole compressor including the rotating body 16 is enclosed in the heating medium atmosphere, then the power of a prime mover 1 is transmitted to the compressor 2 through the thin film case 19 by means of a transmission mechanism 22. Therefore, the injection quantity of the heating medium into the case 19 can be reduced compared with a case that encloses the prime mover and the compressor wholly, and also production and assembly can be facilitated by making the thin film case 19 a simple structure. In addition, the leakage of the heating medium caused by the deterioration of the seal performance at the shaft penetrating section of the compressor 2 can be prevented economically. |
