ABSTRACT:
An absorption refrigerating machines-group apparatus that can be installed at reduced cost and prevent the occurrence of abnormal situations due to the unexpected suspension of the operation of a cooling water pump is provided. The absorption refrigerating machines-group apparatus according to the invention comprises a control panel 200 for issuing control signals, an adapter 300 having a control section 310 for relaying control signals and absorption refrigerating machines 100A, 100B, 100C having respective control sections 80, said control sections 310 and 80 being connected by a telecommunications line L51. When a signal for suspending the operation of the shared cooling water pump is relayed, the currently operating absorption refrigerating machines are brought into a temporary state that allows the operation of the cooling water pump P2 to be suspended through an exchange of signals between the control sections 310 and 80. After obtaining a "pump suspension signal" from each and every one of the absorption refrigerating machines, the control section 310 suspends the operation of the cooling water pump P2. The control section 310 can also suspend the operation of the cooling water pump P2 by seeing the signal representing the operation of the value-setting section 330 and determining if the pump sharing arrangement or the individual pump arrangement is currently selected.
