Understanding vacuum body in freezer

Filter 2 holes

Before filling freon refrigeration units we are required to do so refrigerant vacuum fill system completely pure or mixed with other substances and the most important in this vacuum process is removing the water content that might be carried in with the air circulation system if we let the freon refrigerator improved open too long, the pressure to be achieved when the vacuuming is vacuum pressure until -30psi or more, with pressure as empty as it
at room temperature, the water will evaporate and be carried out with air, special machines to do this step the Vacuum Pump (Vacuum Pump) but can also use other engines such as a refrigerator compressor, air compressor (with modifications) or the refrigerator compressor itself that popular among technicians as vacuum cooling the body.
Vacuum body is actually not able to remove all the air and water because that will be issued only existing in it's own compressor and evaporator, but we can cover the shortage of ways to fill it with a bit of freon and let the freon out again through the capillary discharge, before making such a vacuum have described above may readers already know the steps initially, but if there are not schools should I describe here for a refrigerator that has made the system leak repair, replace compressor etc:

 

Various filters

- Replace the filter or strainer with the best quality and contains a molecular sieve.
- Drain the system using Freon R-11 or Freon other types of more environmentally friendly (recommendation).
- Fill in the appropriate number on the nameplate freon and suitable or recommended course.
- Especially for Freon R-600 and other hydrocarbon materials are prohibited to light a fire when charging and when the charging is usually closing pipe welding was banned for the flammable refrigerant types.
