What should be done after the load of the 1 ton chiller is damaged?

1. Reasons and solutions for motor overload:

There is an excessive amount of refrigerant in the LC -25°C ~ -5°C Low Temperature Chillers, which leads to overloading of the unit. It is necessary to immediately discharge the excess refrigerant.

When selecting a thermal relay, it does not match. It is necessary to purchase a suitable thermal relay and set new parameters.

The selection of a 1-ton chiller is too small, resulting in ineffective results. It is necessary to replace it with a higher power chiller.

If the compressor is damaged, resulting in overload, it is necessary to contact the purchasing manufacturer in a timely manner to resolve the compressor damage situation.

2. Reasons and solutions for abnormal pressure alarm:

If the inlet and outlet of the pipeline are not open, immediately open the inlet valve.

The industrial chiller pipeline is blocked. At this time, it is necessary to immediately check the blockage of the pipeline in the chiller system and immediately clear the blocked pipeline.

3. If it has been determined that the compressor is damaged and completely unusable, we should replace it with a new one as follows:

Remove the drying filter and use a temporary detachable connecting pipe or copper pipe joint to connect the short circuit part;

Inject cleaning agent into the pipeline system to clean the circulating flow, and if necessary, replace the cleaning agent for multiple cleaning;

Blow dry the entire system with nitrogen gas at a pressure of 10kg/cm2 until there is no residual cleaning agent;

Install a good compressor and drying filter, and use nitrogen gas with a pressure of 10kg/cm2 to detect leakage. If there is no leakage, the remaining nitrogen can be discharged into the atmosphere through the high-pressure corner valve;

At the same time, vacuum the high and low voltage ends to 1000 micro, and then check all power supplies and electronic control systems;

Add liquid refrigerant and wait until the refrigerant content reaches 80%~90% before starting the machine for testing. Note: The compressor must be heated for 2 hours.

Replace the refrigerant oil of the compressor and observe the oil usage during compressor operation.
