Document Type and Number:
WIPO Patent Application WO/2022/230955
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle system capable of recovering more refrigerant than when the refrigerant is stored in an outdoor unit. A refrigeration cycle system 1 is provided with a refrigeration cycle device (100) and a refrigerant storage unit (200). The refrigeration cycle device (100) includes an indoor unit (110), an outdoor unit (120), gas-side communication piping (131), and liquid-side communication piping (132). The refrigerant storage unit (200) stores refrigerant that is in a refrigerant circulation path (150). The refrigerant storage unit (200) communicates with the refrigerant circulation path (150) by first storage unit piping (221) and second storage unit piping (222). The first storage unit piping (221) communicates first refrigerant piping (121b) of an outdoor refrigerant flow path (121) and the refrigerant storage unit (200) or the gas-side communication piping (131) and the refrigerant storage unit (200). The second storage unit piping (222) communicates second refrigerant piping (121c) of the outdoor refrigerant flow path (121) and the refrigerant storage unit (200).
