Zusammenfassung: | A refrigerant recovery device according to an embodiment of the present invention may comprise: a refrigerant transport system which recovers a first refrigerant from a target device to a refrigerant container, or injects the same from the refrigerant container into the target device; and a heat pump system which circulates a second refrigerant to heat or cool the first refrigerant. Here, the refrigerant transport system may comprise: a first compressor compressing the first refrigerant; a first heat exchanger which communicates with the refrigerant container and allows the first refrigerant and the second refrigerant to exchange heat; and a first four-way valve which allows one between a suction unit and a discharge unit of the first compressor to communicate with the target device, and the other one to communicate with the first heat exchanger. In addition, the heat pump system may comprise: a second compressor compressing the second refrigerant; a second heat exchanger in which the second refrigerant is condensed or evaporated, and which is connected to the first heat exchanger by a circulation flow path; and a second four-way valve which allows one between a suction unit and a discharge unit of the second compressor to communicate with the first heat exchanger, and the other one to communicate with the second heat exchanger. Therefore, the recovery speed and the injection speed of the refrigerant can be increased.
본 발명의 실시예에 따른 냉매 회수장치는, 제1냉매를 대상기기에서 냉매용기로 회수하거나 냉매용기에서 대상기기로 주입하는 냉매 이송시스템; 및 제1냉매를 가열 또는 냉각하는 제2냉매를 순환시키는 히트펌프 시스템을 포함할 수 있다. 냉매 이송시스템은, 제1냉매를 압축하는 제1압축기; 냉매용기와 연통되고 제1냉매와 제2냉매를 열교환시키는 제1열교환기; 및 제1압축기의 흡입부 및 토출부 중 어느 하나를 대상기기와 연통시키고, 다른 하나를 제1열교환기와 연통시키는 제1사방변을 포함할 수 있다. 히트펌프 시스템은, 제2냉매를 압축하는 제2압축기; 제2냉매가 응축 또는 증발되고 제1열교환기와 순환유로로 연결된 제2열교환기; 및 제2압축기의 흡입부 및 토출부 중 어느 하나를 제1열교환기와 연통시키고, 다른 하나를 제2열교환기와 연통시키는 제2사방변을 포함할 수 있다. |
