摘要： A refrigeration system includes a first device, a second device communicably connected to the first device via a first cable and a second cable, and a refrigerant pipe configured to cause refrigerant circulation to the first device or the second device, in which the first device includes a first circuit configured to short-circuit the first cable and the second cable upon detection of abnormality relevant to refrigerant leakage, and the second device includes a second circuit configured to start protection behavior against abnormality when the first cable and the second cable are short-circuited.
