As an industrial equipment, common failures of chillers are inevitable, just like a car that will inevitably encounter some problems over time. In severe cases, the chiller unit suddenly shuts down, and if this situation is not resolved properly, it may lead to serious accidents. Now let Aoqi take you to understand how to deal with the sudden shutdown of the chiller compressor?

1、Sudden power outage causing the chiller unit to shut down

During the operation of the refrigeration compressor, if there is a sudden power outage, first disconnect the main power switch, immediately close the suction and discharge valves of the compressor, then close the liquid supply gate valve, and stop supplying liquid to the air conditioning evaporator to prevent the humidity of the evaporator from contracting due to excessive liquid during the next operation of the chiller equipment.

2、Sudden water outage caused the chiller to stop.

If the cooling circulating water is suddenly cut off, the switch power should be immediately cut off and the operation of the refrigeration compressor should be stopped to prevent the working pressure of the refrigeration unit from being too high. After the air compressor is shut down, the suction and exhaust valves as well as the relevant liquid supply valves should be immediately closed. After identifying the cause and eliminating common faults, the power supply should be repaired before restarting the chiller.

3、Common faults and shutdowns of chiller compressor

When the chiller is shut down urgently due to the damage of a certain component of the compressor during operation, if conditions permit, it can be stopped normally according to the actual operation. If there is an emergency situation, the motor switch power should be disconnected, and then the suction and exhaust valves, as well as the supply gate valve, should be closed. If the refrigeration equipment is lacking ammonia or the refrigeration compressor has common faults, the power supply of the production workshop should be disconnected, and anti-virus clothing and masks should be worn for maintenance. At this point, all exhaust fans should be turned on. If necessary, tap water can be used to invert the location of ammonia leakage, making it easier to repair the chiller.

4、Shutdown upon fire

When a fire occurs in an adjacent building, the stability of the refrigeration unit is seriously threatened. Turn off the power, quickly open the exhaust valves of the storage tank, refrigeration unit, ammonia oil filter, air conditioning evaporator, etc., quickly open the emergency ammonia unloader and inlet valve, so that the ammonia solution of the system software is centrally discharged at the emergency ammonia unloading port, diluted with a large amount of water, to prevent the spread of fire accidents and accidents.

The maintenance and upkeep of the chiller unit is a relatively technical matter. To solve common faults of the chiller unit, it is necessary to hire technical personnel. Solving them without authorization is very risky.
