The inspector of the refrigeration pump room is familiar with the system's pipelines.
Don't panic in case of emergencies, take measures and make judgments.
If there is water leakage in the pump room pipeline, turn off the power supply of the equipment.
Close the water leakage control valve, and close both the front and rear pipelines.
The control cabinet, motor, and distribution cabinet of the unit must be protected against water immersion hazards.
Ensure the waterproof materials are well protected and notify the relevant personnel.
Urgently investigate the cause of the water drainage issue and eliminate the faulty point.
In case of a sudden power outage, immediately shut down the machine and inquire about the cause.
The refrigeration circulating pump starts, and the incoming call takes precedence.
If the power outage lasts for a long time, take care to handle the evaporation and drainage.
The freezing pressure suddenly drops, and the water pump of the refrigeration unit is turned off.
Close the valves of the water collection tank, and inspect the equipment pipelines simultaneously.
When supplying and returning water to the faulty equipment, the valve must be tightly closed.
After controlling the leakage point, open the source of the water distribution and collection tank.
The chilled water pump is also turned on, and the system is operating normally with a delay.
The refrigeration unit has also been turned on, but the troubleshooting is not over yet.
Local water replenishment and exhausting, ensuring good operation.
The circulating water pump suddenly stopped due to a fault during operation.
For the refrigeration unit, manual shutdown measures are taken.
Other units will operate on a standby basis and be ready for timely switching.
If the chilled water pump malfunctions, observe the temperature of the chilled water.
When the temperature is above 7 degrees Celsius, it is advisable to release the chilled water.
The water flow is slow after opening the drain valve at the bottom of the evaporator.
Prevent the evaporator tube bundle from being frozen and damaged due to low evaporation temperature.
After repairing the faulty water pump, put it back into operation and conduct another test.
When the unit experiences a malfunction, the scope of shutdown and pressure relief shall be implemented.
Observing the color through an oil immersion lens, a large amount of foam appears.
Upon judging the tube bundle to be ruptured, the circulating pump should be promptly shut down.
The valves of the water inlet and outlet units must also be tightly closed.
At the same time, turn on the exhaust fan to fully vent the leaked fluorine gas.
The repair has been put into trial operation, and the unit is operating normally.
If there is a fire near the refrigerator, stop operation and turn off the power,
Do not operate electrical equipment and initiate the fire emergency plan.
Do not use water to extinguish fires with equipment, and ensure proper operation of air conditioning systems.
In case measures are taken, immediately report to the leaders and security personnel.
