Abstract (en)
[origin: EP3859253A1] Provided is a measure against a refrigerant leak. A heat load processing system (100) has a plurality of refrigerant circuits (RC) and includes a plurality of device units (R1), a casing (50) that collectively houses the plurality of device units (R1) configuring the different refrigerant circuits (RC), a refrigerant leak detection unit (70, 84) that individually detects a refrigerant leak in the respective refrigerant circuits (RC), and a controller (80). The device units (R1) include a heat exchanger (33) that is connected to a refrigerant pipe (Pb, Pc) and a heat medium pipe (Hb, Hc, Hd) as a device configuring one of the refrigerant circuits (RC). When the refrigerant leak detection unit detects the refrigerant leak, the controller (80) performs refrigerant leaking circuit identification processing for identifying a refrigerant circuit (RC) in which the refrigerant leak is occurring (refrigerant leaking circuit) and a refrigerant leak third control for changing an operating state of a predetermined refrigerant circuit (RC) based on a result of the refrigerant leaking circuit identification processing.
