How to distinguish whether the air conditioner is variable frequency? Analysis of hot topics on the Internet in the past 10 days
With the arrival of high temperatures in summer, air conditioners have become an essential appliance in homes and offices. Recently, the discussion about "inverter air conditioners" has become one of the hot topics. Many consumers are confused when faced with the choice between "variable frequency" and "fixed frequency" when purchasing air conditioners. This article will combine the hot content on the Internet in the past 10 days to provide you with a detailed analysis of how to distinguish whether an air conditioner is a variable frequency air conditioner, and provide structured data to help you make a wise choice.
1. The core difference between variable frequency air conditioners and fixed frequency air conditioners
The biggest difference between inverter air conditioners and fixed frequency air conditioners is the way the compressor operates. The compressor of the inverter air conditioner can automatically adjust the operating frequency according to the indoor temperature, thereby achieving more precise temperature control and higher energy efficiency ratio. The compressor of a fixed-frequency air conditioner can only run at a fixed frequency and will stop when it reaches the set temperature, causing large temperature fluctuations.
| Comparative item | Inverter air conditioner | Fixed frequency air conditioner |
|---|---|---|
| How the compressor works | Variable frequency operation | Fixed frequency operation |
| temperature control | Accurate, small fluctuation | Larger fluctuations |
| Energy efficiency ratio | High (usually above 3.5) | Lower (usually around 3.0) |
| price | higher | lower |
| noise | lower | higher |
2. How to judge the inverter air conditioner by its appearance and logo
1.Product model identification:Most inverter air conditioners will include the words "BP" or "Inverter" in the model number. For example, the model of a certain brand of inverter air conditioner is KFR-35GW/BP, where "BP" means inverter.
2.Energy efficiency label:The energy efficiency label of inverter air conditioners is usually the "new energy efficiency label", the energy efficiency level is Level 1 or Level 2, and the energy efficiency ratio (APF) is high. Most fixed-frequency air conditioners have level 3 energy efficiency.
| Judgment basis | Inverter air conditioner features | Fixed frequency air conditioner characteristics |
|---|---|---|
| Model identification | Contains the words "BP" or "frequency conversion" | No special identification |
| energy efficiency label | New energy efficiency label, level 1-2 | Old energy efficiency label, level 3 |
| price range | More than 2,500 yuan | 1500-2500 yuan |
3. Judge inverter air conditioners through usage experience
1.Temperature stability:The inverter air conditioner will keep the indoor temperature stable during operation, and the fluctuation range will be within ±0.5°C. The temperature fluctuation of fixed-frequency air conditioners may reach ±2℃.
2.Noise level:The inverter air conditioner has low noise when running at low speed, usually around 20 decibels; while the fixed frequency air conditioner has a louder noise when starting.
3.power consumption:Inverter air conditioners save more energy during long-term use, especially at night.
4. Popular inverter air conditioner brands and models on the entire network in the past 10 days
According to the popularity of discussions on major e-commerce platforms and social media, the following inverter air conditioner models have attracted much attention recently:
| brand | Popular models | Energy efficiency level | price range |
|---|---|---|---|
| Gree | Yunjia KFR-35GW/(35530)FNhAk-B1 | Level 1 | 2999-3299 yuan |
| Beautiful | Cool power saving KFR-35GW/N8KS1-1 | Level 1 | 2799-3099 yuan |
| Haier | Jingyue KFR-35GW/01KGC81U1 | Level 1 | 2699-2999 yuan |
| Hualing | N8HE1Pro | Level 1 | 2299-2599 yuan |
5. Purchase suggestions
1.Choose based on duration of use:If you use the air conditioner for more than 6 hours a day, it is recommended to choose an inverter air conditioner, which will save more energy during long-term use.
2.Pay attention to energy efficiency ratio:The higher the energy efficiency ratio (APF), the better the energy saving effect. The APF of high-quality inverter air conditioners currently on the market can reach above 5.0.
3.Consider the installation environment:Places such as bedrooms that require a quiet environment are more suitable for inverter air conditioners.
4.Compare after-sales services:The technology of inverter air conditioners is complicated, so it is recommended to choose a brand with complete after-sales service.
Through the above methods, you can easily distinguish between variable frequency air conditioners and fixed frequency air conditioners, and make the best choice based on your needs. There have been frequent air conditioner promotions recently, and consumers are advised to compare prices and preferential policies on different platforms before purchasing.
