| The function of vacuuming
Remove air and moisture: Non-condensable gases such as oxygen and nitrogen in the refrigeration system can occupy the condenser space, leading to increased discharge pressure and reduced efficiency. Meanwhile, moisture may cause ice blockages or corrosion of components.
Ensuring System Security: Residual oxygen in the air reacts with the refrigerant to produce acidic substances, which can corrode the compressor's insulation layer and metal components, leading to motor burnout or a shortened system lifespan.
| How to Operate
Equipment Selection: A dedicated vacuum pump (such as one specifically designed for the refrigeration industry) must be used to ensure the vacuum level meets the required standard.
Operating Procedures:
Connect the vacuum pump to the refrigeration system and turn on the pump to extract air.
Continues until the system pressure stabilizes at the set value (typically below -0.1 MPa);
Observe the pressure gauge, and once you confirm there are no pressure fluctuations, turn off the vacuum pump.
| Notes |
Do not use the compressor itself to evacuate air, as this may damage the motor when power is applied.
After evacuating, refrigerant must be charged immediately to prevent the system from being exposed to air.
