Document Type and Number:
Japanese Patent JP2021173435
Kind Code:
A
Abstract:
To provide a refrigeration cycle device capable of suppressing formation of a region where a concentration of a leaked refrigerant becomes a constant level or more even when refrigerant leakage occurs along with a refrigerant recovery work performed in the case where a pumping-down operation has not been performed normally.SOLUTION: The refrigeration cycle device includes: a refrigerant circuit in which an indoor heat exchanger 3, a compressor 7 and an outdoor heat exchanger 4 are connected in a circulating manner by refrigerant piping 10 filled with a refrigerant; a pumping-down operation instruction section 111 outputting a recovery operation instruction signal for operating the compressor 7 to perform a recovery operation for recovering the refrigerant to an outdoor unit 2 side; and a pumping-down abnormality detection section 112 detecting occurrence of an abnormality in the recovery operation when the pumping-down operation instruction section 111 has output the recovery operation instruction signal. The outdoor unit 2 includes an outdoor fan 6 operated when the pumping-down abnormality detection section 112 detects occurrence of an abnormality in the recovery operation.SELECTED DRAWING: Figure 3
