Abstract (en)

[origin: EP3418655A1] Provided is a refrigeration apparatus which, even if refrigerant leakage occurs, can keep the extent of the refrigerant leakage small, effectively utilize portions in which leakage is not occurring, and inhibit contamination of a refrigerant circuit with air. When refrigerant leakage is detected inside either of a first usage unit (50) and a second usage unit (60) that are connected in parallel to each other, a controller (70) closes a shutoff valve on the upstream side of a usage-side heat exchanger of the leaking unit and performs control so as to ensure a state in which, with respect to a check valve on the downstream side of the usage-side heat exchanger of the leaking unit, the refrigerant pressure on the downstream side is greater than the refrigerant pressure on the leaking unit usage-side heat exchanger side.
