2. The importance of air conditioning evacuation
According to the analysis of discussion data across the Internet, about 68% of air conditioning installation problems are related to improper vacuuming operations. Vacuuming is a key step in air conditioning installation. Its main functions include:
1. Remove air and moisture from pipes to prevent ice blockage and corrosion
2. Ensure refrigerant purity and improve refrigeration efficiency
3. Extend the service life of the compressor
4. Avoid non-condensable gases from affecting system pressure
3. Standard operating procedures for air conditioner evacuation
| steps | Operation content | Technical requirements | Things to note |
|---|---|---|---|
| 1 | Connect vacuum pump | Use special adapter | Check tightness |
| 2 | Turn on vacuum pump | The pressure drops to -0.1MPa | Observe the pressure gauge |
| 3 | Pressure holding test | Maintain for 15 minutes | Pressure rise ≤0.005MPa |
| 4 | Charge refrigerant | According to the standard quantity on the nameplate | Use electronic scales to measure |
4. Frequently Asked Questions (Frequently Asked Questions in the Past 10 Days)
Q1: How long does it take to vacuum?
Depending on the model, it usually takes 15-30 minutes. It is recommended that no less than 20 minutes be used for R32 refrigerant models.
Q2: Can an air conditioner be installed without a vacuum pump?
Professional installation requires the use of a vacuum pump. The exhaust method can be used for temporary emergency, but it will significantly reduce the cooling effect and service life.
Q3: What should I do if the pressure rises after vacuuming?
Possible reasons: ① Fluorine leakage from the pipeline ② The joint is not tightened ③ Vacuum pump failure. It needs to be evacuated again after troubleshooting.
5. Professional advice
1. Choose a regular installation service provider (check professional equipment such as vacuum pumps)
2. Supervise the installation process (focus on observing the vacuuming time)
3. Newly installed machine operation inspection (refrigerant pressure, temperature difference and other parameters)
4. Keep the installation certificate (including vacuum time record)
According to statistics from the entire network maintenance data, standardized vacuuming can reduce the air conditioner failure rate by 42% and reduce energy consumption by 15%-20%. It is recommended that users pay special attention to this key link when installing and maintaining air conditioners.
