The refrigerating cycle unit comprises: a compressor in which a refrigerant is compressed; a first heat exchanger in which the refrigerant compressed by the compressor is condensed; an expansion device in which the refrigerant condensed by the first heat exchanger expands; and a second heat exchanger in which the refrigerant expanded by the expansion device evaporates.

As shown in FIG. 5, The refrigerating cycle unit 1 may be integrated with the outdoor unit 7 so as to be integrated with the refrigerating cycle unit 1. [
즉, 부스터 모듈(5)은 도 4 및 도 5에 도시된 바와 같이, 실외기(O)에 선택적으로 장착될 수 있다. That is, the booster module 5 can be selectively installed in the outdoor unit O, as shown in FIGS.
도 6은 본 발명에 따른 히트 펌프 일실시예의 부스터 모듈이 설치되지 않을 때와 부스터 모듈이 설치되었을 때를 비교한 P-h 선도이다.  6 is a P-h diagram showing a comparison between when the booster module is not installed and when the booster module is installed in the heat pump according to the present invention.
부스터 모듈(2)이 설치되지 않은 경우 냉매는 통상적인 압축,응축,팽창,증발 과정을 거치면서 도 4에 점선으로 도시된 바와 같이, a->b'>c ->f ->a의 과정이 진행된다. When the booster module 2 is not installed, the refrigerant undergoes a process of a-> b '> c -> f -> a, as shown by the dotted line in FIG. 4 while undergoing the usual compression, condensation, expansion, .
반면에, 냉매는 부스터 모듈(2)이 추가 설치된 경우 냉매는 압축,응축,팽창,팽창,증발 과정을 거치면서 도 6에 실선으로 도시된 바와 같이, 냉a->b->c->d->e->f->a의 과정으로 진행되고, 제 1 열교환기(14)에서 유출된 냉매 중 일부가 부스터 모듈(2)에서 팽창, 압축 과정을 거치면서 도 6의 d->g->h->b의 과정으로 진행되며, 히트 펌프는 부스터 모듈(2)이 설치되지 않는 경우 보다 전체적으로 효율이 상승되면서 압축일이 감소될 수 있다. On the other hand, when the booster module 2 is additionally installed, the refrigerant is cooled to a-> b-> c-> d (d) as shown by a solid line in FIG. 6 while the refrigerant undergoes compression, condensation, expansion, g-> g-> a-, a part of the refrigerant flowing out of the first heat exchanger 14 is expanded and compressed in the booster module 2, > h-> b, and the efficiency of the heat pump is increased as compared with the case where the booster module 2 is not installed, so that the compression work can be reduced.
즉, 압축기(10)와 부스터 압축기(90)로 공급되는 전체 소비전력은 감소되고, 특히 실외가 저온인 저온 난방 능력이 향상된다. 그리고, 부스터 모듈(2)의 설치된 경우는 부스터 모듈(2)이 설치되지 않는 경우 보다 압축기(10)의 최대 관리 온도는 상대적으로 낮게 되고, 압축기(10)의 신뢰성은 향상될 수 있다. That is, the total power consumption supplied to the compressor 10 and the booster compressor 90 is reduced, and the low-temperature heating capability, particularly in a low outdoor temperature, is improved. When the booster module 2 is installed, the maximum management temperature of the compressor 10 is relatively lower than in the case where the booster module 2 is not installed, and the reliability of the compressor 10 can be improved.
