Conversely, when the absorption chiller is started, the equipment board (35) outputs an operation signal to the chilled water pump (23) and the chilled water pump (28), but the chilled water pump (23) or the chilled water pump If (28) is out of order, or if the pumps (23) and (28) do not start due to malfunction of the equipment panel (35), the chilled water pump interlock signal or cooling from the equipment panel (35) Water pump interlock signal is not output. Therefore, the signal discrimination device (34) does not output a signal to the controller (31), and the timer (33) continues counting. Then, after the timer (33) starts counting, that is, when a predetermined time (T) elapses as shown in FIG. 2 after the operation manager operates the operation switch (32), the timer (33) starts counting. And outputs a signal to the signal discrimination device (34). The signal discrimination device (34) operates based on this signal,
Since an interlock signal is not input, an abnormal signal is output, and this abnormal signal is transmitted from the control panel (31) to the equipment panel (35).
Output to When an abnormal signal is input, the alarm (36) of the equipment panel (35) operates, the buzzer sounds, and the light emitting element emits light. Further, a signal from the signal discriminating device (34) is also inputted to a display (notification device) (30A) of the control panel (30), and a light emitting element such as an LED blinks. Alarm (36) or Display (30
By the operation of A), the operation manager knows that the absorption chiller does not start due to the abnormality of the chilled water pump (23) or the chilled water pump (28). Then, the pumps (23) and (28) are inspected and repaired. When repairs are completed and the operation manager operates the operation switch (32) and the operation of each pump (23) and (28) starts, each interlock signal is output from the equipment panel (35) to the control panel (30). As a result, the absorption refrigerator starts operating.

According to the above embodiment, if the chilled water pump (23) or the chilled water pump (24) does not start operation due to a failure or the like at the start of the operation of the absorption chiller, the chilled water pump or the chilled water is cooled from the equipment panel (35). Water pump interlock signal is not output. For this reason, at the same time as the time of the timer (33) of the control panel (30) has expired, it is determined that the equipment such as the pump equipment has started up, and is output as an abnormality notification signal notifying the necessity of the start-up maintenance service. The alarm is issued by the operation such as (36). The monitoring time of the interlock signal by the timer (33) is short enough to confirm the normal start of operation of the equipment such as the pump equipment, for example, 1 minute.
After operating 2), it is possible to know the failure of pumps and other equipment in a short time, and to start checking for and repairing abnormalities as early as possible, thereby minimizing the delay in starting.
