2. Detailed explanation of the principle of air conditioning refrigeration
Air conditioning refrigeration mainly relies on the cycling changes of refrigerant:
1.Compression process: The compressor compresses the low-temperature and low-pressure gas refrigerant into high-temperature and high-pressure gas
2.Condensation process: High-temperature and high-pressure gas expels heat in the outdoor unit condenser and turns into medium-temperature and high-pressure liquid
3.Expansion process: Decompression through the throttling device, it becomes a low-temperature and low-pressure liquid
4.Evaporation process: Low-temperature and low-pressure liquid absorbs heat in the indoor unit evaporator and turns into low-temperature and low-pressure gas
3. Tips for improving the refrigeration effect of air conditioners
| method | Operation Instructions | Improved results |
|---|---|---|
| Set the temperature reasonably | It is recommended to save 7-10% of electricity for every 1℃ increase. | ★★★★☆ |
| Clean the filter regularly | Clean every 2 weeks, dust accumulation will reduce refrigeration efficiency | ★★★★★ |
| Avoid direct sunlight | Use curtains to reduce heat load | ★★★☆☆ |
| Use with fans | Promote air circulation, somatosensory temperature can drop by 2-3℃ | ★★★☆☆ |
4. Solutions for FAQs in air conditioners
1.Air conditioner does not refrigerate: Check power supply, mode settings, filter cleanliness, refrigerant volume
2.Poor refrigeration effect: It may be due to poor heat dissipation of the external unit or poor heat insulation performance in the room
3.Problem of abnormal noise: Check whether the fan blades are loose or the bearing is oil-deficient
4.Water leakage problem: Check whether the drain pipe is blocked or the installation is not level
5. Air conditioner purchase suggestions
| Room area | Suggested match | Number of people applicable | Reference price |
|---|---|---|---|
| 10-15㎡ | 1 horse | 1-2 people | 1500-2500 yuan |
| 16-20㎡ | 1.5 horses | 2-3 people | 2000-3500 yuan |
| 21-30㎡ | 2 horses | 3-5 people | 3000-5000 yuan |
| 31-40㎡ | 3 horses | 5-8 people | 5000-8000 yuan |
6. Future development trends of air conditioning technology
1.Intelligent control: Automatically adjust the optimal operating mode through AI algorithm
2.Environmentally friendly refrigerant: Gradually phase out Freon and adopt new refrigerants such as R32
3.Energy efficiency: The energy efficiency ratio of APF continues to improve, and some models have reached more than 5.0
4.Health functions: Increase sterilization, formaldehyde removal, air purification and other functions
Through the above content, I believe you have a more comprehensive understanding of air conditioning and cooling. Rational use of air conditioners can not only improve living comfort, but also save energy and protect the environment. It is recommended to regularly maintain the air conditioning equipment to ensure it is always in optimal working condition.
