首先，在步骤S1中，室内单元20a在从电源21a被供给电力的状态下开始各种处理。室内单元20a在该状态下使各结构发挥功能，能够进行制冷或制热等空调运转。First, in step S1, the indoor unit 20a starts various processes while being supplied with electric power from the power supply 21a. In this state, the indoor unit 20a enables each of its components to function, and can perform air-conditioning operations such as cooling and heating.

在步骤S2中，室内单元20a的切断检测部27a判定是否从电源21a切断了电力供给。在步骤S2中切断检测部27a未检测到来自电源21a的电力的切断的情况下(S2：否)，室内单元20a继续进行空调运转，切断检测部27a继续进行判定。In step S2, the disconnection detection part 27a of the indoor unit 20a determines whether the electric power supply from the power supply 21a was disconnected. In step S2, when the cutoff detection part 27a does not detect the cutoff of the electric power from the power supply 21a (S2: No), the indoor unit 20a continues air-conditioning operation, and the cutoff detection part 27a continues to make a judgment.

另一方面，在步骤S2中切断检测部27a检测到来自电源21a的电力的切断的情况下(S2：是)，室内单元20a将室内单元20a的电力的供给源从电源21a切换为第1供电单元30a。(步骤S3)。换言之，室内单元20a开始经由传输路径40从第1供电单元30a供给辅助电源。On the other hand, when the disconnection detection part 27a detects the disconnection of the electric power from the power supply 21a in step S2 (S2: Yes), the indoor unit 20a switches the supply source of the electric power of the indoor unit 20a from the power supply 21a to the first power supply. Unit 30a. (step S3). In other words, the indoor unit 20a starts supplying auxiliary power from the first power supply unit 30a via the transmission path 40 .

在步骤S4中，室内单元20a经由传输路径40向室外单元10输出切断信号。In step S4 , the indoor unit 20 a outputs a cutoff signal to the outdoor unit 10 via the transmission path 40 .

在步骤S5中，室外单元10的室外控制部15对室内单元20a发送膨胀阀24a的开度调整指示。开度调整指示是使膨胀阀24a全开、全闭、增大开度、或减小开度等指示。由此，能够进行室内单元20a的回油运转等。另外，室外单元10的室外控制部15也可以对室内单元20a发送指示各种致动器动作的动作指示。室内单元20a的室内控制部25a根据动作指示进行各种致动器的控制。In step S5, the outdoor control unit 15 of the outdoor unit 10 transmits an instruction to adjust the opening degree of the expansion valve 24a to the indoor unit 20a. The opening adjustment instruction is an instruction to fully open or fully close the expansion valve 24a, to increase the opening degree, or to decrease the opening degree. Thereby, the oil return operation of the indoor unit 20a, etc. can be performed. In addition, the outdoor control unit 15 of the outdoor unit 10 may transmit an operation instruction instructing the operation of various actuators to the indoor unit 20a. The indoor control unit 25a of the indoor unit 20a controls various actuators according to operation instructions.

在步骤S6中，室内单元20a的室内控制部25a根据来自室外单元10的开度调整指示对膨胀阀24a的开度进行调整。In step S6, the indoor control unit 25a of the indoor unit 20a adjusts the opening degree of the expansion valve 24a based on the opening degree adjustment instruction from the outdoor unit 10.

在步骤S7中，室内单元20a的切断检测部27a判定来自电源21a的电力是否被切断。换言之，判定来自主电源的供电是否恢复。在步骤S7中切断检测部27a检测到来自电源21a的电力的切断的情况下(S7：是)，切断检测部27a反复进行判定，继续进行来自第1供电单元30a的供电。In step S7, the disconnection detection part 27a of the indoor unit 20a determines whether the electric power from the power supply 21a is cut off. In other words, it is determined whether or not the power supply from the main power supply is restored. When the disconnection detection part 27a detects the disconnection of the electric power from the power supply 21a in step S7 (S7: YES), the disconnection detection part 27a repeats a determination, and continues the power supply from the 1st power supply unit 30a.

另一方面，在步骤S7中切断检测部27a未检测到来自电源21a的电力的切断的情况下(S7：否)，换言之，在再次开始来自主电源的供电的情况下，将室内单元20a的电力供给源从第1供电单元30a切换为电源21a。(步骤S8)。On the other hand, in step S7, when the disconnection detection part 27a does not detect the disconnection of the electric power from the power supply 21a (S7: No), in other words, when restarting the power supply from the main power supply, the indoor unit 20a is switched to The power supply source is switched from the first power supply unit 30a to the power supply 21a. (step S8).

以上，在室内单元20a的主电源被切断的情况下，结束从第1供电单元30a经由传输路径40向室内单元20a供给辅助电源的处理。As described above, when the main power supply of the indoor unit 20a is cut off, the process of supplying the auxiliary power supply from the first power supply unit 30a to the indoor unit 20a via the transmission path 40 ends.

(4)特征(4) Features

本实施方式的制冷剂循环系统1具有制冷剂循环、第1供电单元30a、第2供电单元30b、第1传输路径41和第2传输路径42。制冷剂循环包含作为热源单元的室外单元10、作为第1利用单元组的第1室内单元20A、以及作为第2利用单元组的第2室内单元20B。第1供电单元30a在第1室内单元组20A的各室内单元20a、20b、20c的电源被切断时，对电源被切断的利用单元供给辅助电源。第1供电单元30a是与室外单元10分体的单元。第2供电单元30b在第2室内单元组20B的各利用单元20d、20e、20f的电源被切断时，对电源被切断的利用单元供给辅助电源。第2供电单元20B是与室外单元10分体的单元。第1传输路径41连接室外单元10和第1供电单元30a。第2传输路径42连接第1供电单元30a和第2供电单元30b。第2供电单元30b经由第1供电单元30a而与室外单元10连接。The refrigerant cycle system 1 of the present embodiment includes a refrigerant cycle, a first power supply unit 30 a , a second power supply unit 30 b , a first transmission path 41 , and a second transmission path 42 . The refrigerant cycle includes outdoor unit 10 as a heat source unit, first indoor unit 20A as a first usage unit group, and second indoor unit 20B as a second usage unit group. The first power supply unit 30a supplies auxiliary power to the use unit whose power is cut off when the power supply to each of the indoor units 20a, 20b, and 20c of the first indoor unit group 20A is cut off. The first power supply unit 30a is a separate unit from the outdoor unit 10 . The second power supply unit 30b supplies auxiliary power to the use units whose power is cut off when the power to each of the use units 20d, 20e, and 20f of the second indoor unit group 20B is cut off. The second power feeding unit 20B is a separate unit from the outdoor unit 10 . The first transmission path 41 connects the outdoor unit 10 and the first power supply unit 30a.
