The damage and resolution of freezer parts have long been an enduring topic, and the chest freezer manufacturer hopes to provide you with some references.
1. Lack of refrigerant: When supplementing refrigerant, use a filter in series between the process port and the connecting pipe valve of the refrigerant cylinder. This is mainly used to filter out impurities and residual water in the refrigerant, which can prevent ice blockage.
2. Replacing the refrigerating machine oil: When maintaining and replacing the refrigerating machine oil in the refrigeration cycle system, the refrigerating machine oil can be heated to 100 ℃ with an induction cooker and kept at a constant temperature for a period of time. The residual water in the refrigerating machine oil can be evaporated and cleaned up before proceeding. replace. This can prevent the occurrence of ice blockage when heating the refrigerator oil at a constant temperature.
3. Replacing the compressor unit: For the refrigeration cycle system, when the compressor unit is maintained and replaced, the refrigerating machine oil in the compressor unit should be poured or released. Dry the refrigerating machine oil according to step 2. When the refrigerating machine oil is 75 degrees Celsius, add it to the compressor unit, increase or decrease it according to the standard amount, close the air return port and the process port, and open the air outlet.
4. Piping problems in the refrigeration cycle system: First, replace the damaged pipe section or the loose connection of the missing spot welding and repair the threaded connection, redo and tighten it. In order to ensure that there is no leakage in the high-pressure test of the pipeline. The high-pressure section and the low-pressure section of the refrigeration cycle system are flushed with carbon tetracarbide and purged with nitrogen and sealed for later use.
