Refrigerator emergency plan

　　 Refrigeration pump room inspector, familiar with the system pipeline.

　　 Do not panic in an emergency, take measures and judgements.

　　 If water runs in the pump room pipeline, turn off the power to the equipment.

　　 Close the running water control valve, and the pipeline is closed at the same time.

　　The unit control cabinet and motor, and the power distribution cabinet are waterproof.

　　 The waterproof material is well protected, and the relevant personnel should be notified.

　　 Urgent drainage to find the cause and eliminate the point of failure.

　　 In case of a sudden power failure, immediately shut down and inquire about the cause.

　　 The refrigeration cycle pump is started, and the call comes first.

　　 If there is a long power outage, evaporate and drain water seriously.

　　 The freezing pressure drops suddenly and the water pump of the refrigeration unit is turned off.

　　 The valve of the manifold water tank is closed, and the equipment pipeline is looked at at the same time.

　　 If the failed equipment supplies and returns water, close the valve tightly.

　　 After controlling the leaking point, turn on the source of the diversity tank.

　　 The chilled water pump is also turned on, and the normal operation of the system is delayed.

　　 The refrigeration unit is also turned on, and the troubleshooting is not complete.

　　 Local water supply and exhaust gas, normal operation is in good condition.

　　 The circulating water pump suddenly fails and shuts down the power supply.

　　 Corresponding to the refrigeration unit, manual stop means is adopted.

　　Other units are running on behalf of others, and they are switched in time.

　　 If the chilled water pump fails, observe the chilled water temperature.

When is greater than 7 degrees Celsius, it is good to release the frozen water.

　　 The water discharge valve at the bottom of the evaporator, the water flow is slow after the call.

　　 Prevent low evaporation temperature and freeze residue of evaporator tube bundle.

　　 After repairing the faulty pump, put it into operation and test again.

　　 When the unit fails, the shutdown pressure relief range is handled.

　　 Through the oil mirror to observe the color, a lot of bubbles are appearing.

　　 To judge the tube bundle rupture, the circulating pump should be shut off quickly.

　　 For units with inlet and outlet valves, the valves should also be closed tightly.

　　 Turn on the exhaust fan at the same time, and the leaked fluorine gas is exhausted.

　　 The repair was put into trial operation, and the unit was running normally.

　　 There is a fire near the freezer, stop running and turn off the power,

　　 Do not run electrical equipment, start the fire prevention plan.

　　 Water is forbidden for fire extinguishing equipment, and the air conditioner is turned off.

　　 In case of taking measures, report to the leaders and security in an emergency.

　　The accident analysis should be comprehensive, and similar problems should not appear
