How does air conditioning count as electricity consumption? Analysis of hot topics on the Internet in the past 10 days
As high temperatures continue in summer, the power consumption of air conditioners has become a hot topic across the Internet. How to calculate air conditioning power consumption? How to save power and keep cool? This article will combine the hot discussions on the Internet in the past 10 days and use structured data to answer your questions.
1. Calculation formula of air conditioning power consumption
The power consumption of air conditioners mainly depends on the following three factors:
| Influencing factors | Description | Calculation formula |
|---|---|---|
| Cooling power | Marked on the air conditioner energy efficiency label (unit: W) | Power consumption = power × time ÷ 1000 |
| usage time | Actual operating hours | (The unit is kWh) |
| Energy efficiency ratio | The new national standard is APF value (annual energy efficiency ratio) | The higher the APF, the more power you save. |
2. Measured data of power consumption of air conditioners with different numbers of units
Compiled based on popular measured videos on Douyin/Xiaohongshu:
| Number of air conditioners | Refrigeration power(W) | 8 hours power consumption (kWh) | Electricity fee (0.6 yuan/kWh) |
|---|---|---|---|
| 1 horse (26 models) | 650-750 | 5.2-6.0 | 3.12-3.6 yuan |
| 1.5 HP (35 model) | 950-1100 | 7.6-8.8 | 4.56-5.28 yuan |
| 3 horses (72 model) | 2000-2500 | 16-20 | 9.6-12 yuan |
3. Top 5 power-saving techniques hotly discussed across the internet
Organized based on Weibo/Baidu hot search words:
| Ranking | Power saving methods | Principle description | Actual measured power saving rate |
|---|---|---|---|
| 1 | Set above 26℃ | Save 7-10% electricity for every 1°C rise | Up to 30% |
| 2 | Use with fan | Speed up air circulation | Reduce body temperature by 2-3°C |
| 3 | Clean the filter regularly | Reduce wind resistance and improve efficiency | Save 15-20% electricity |
| 4 | Use sleep mode | Automatically adjust temperature and wind speed | Save 25% electricity |
| 5 | Choose an inverter air conditioner | Avoid frequent starts and stops | 30% less power than fixed frequency |
4. Key points of new air conditioning energy efficiency regulations in 2023
The country’s latest GB21455-2023 standard has triggered heated discussions:
| Changes | old standard | new standard | influence |
|---|---|---|---|
| Energy efficiency level | Level 3 | Level 5 | Original level 1 ≈ new level 3 |
| APF requirements | Minimum 3.7 | Minimum 4.0 | Eliminate 15% of inefficient products |
| Test conditions | Single working condition | Year-round simulation | Closer to actual use |
5. Power consumption reminder in special scenes
Notes mentioned in Zhihu’s popular Q&A:
| scene | Electricity characteristics | Suggestions |
|---|---|---|
| Old air conditioner for rent | Energy efficiency ratio is less than 3.0 | Replace filter + outdoor unit dust removal |
| Western room | Cooling load increased by 40% | Install sunshades |
| Open window for use | Power consumption doubled | Be sure to close doors and windows |
Summary:Calculating the electricity consumption of air conditioners requires a combination of three key factors: power, time and energy efficiency ratio. Choosing energy-efficient products, setting temperatures appropriately, and doing routine maintenance can significantly reduce electricity costs. It is recommended that consumers look for the new energy efficiency label when purchasing. Products with an APF value ≥5.0 have more energy-saving advantages.
