          White appliances enter the era of variable frequency

          White appliances enter the era of variable frequency Today, looking at home appliance stores, "frequency conversion" has become the mainstream technology. Inverter air conditioners, frequency conversion washing machines, inverter refrigerators, variable frequency water heaters, variable frequency microwave ovens, etc. are all around. Air conditioners, refrigerators, and washing machines, which are almost all white electric products, have entered the era of frequency conversion. Industry experts believe that the advantages of being more energy-efficient, more efficient, and ultra-quiet are the main reasons why frequency-converting white goods are favored by consumers.

          The air conditioner frequency conversion market accounts for more than 50%

          The new energy-efficiency standard for inverter air conditioners will be formally implemented on October 1 this year. The new standard will introduce a new annual energy consumption efficiency (APF) evaluation index, which will significantly increase the product's access threshold. At present, leading companies including Midea have announced the completion of the R&D switch and production technology preparation for the new APF inverter standard. The analysis pointed out that the air-conditioning industry under the guidance of the new energy efficiency standards will be more energy-efficient.

          The president of the China Household Electrical Appliances Research Institute, Yu Xuwei, introduced that the new inverter air conditioner energy efficiency standard introduced the APF evaluation index, taking into account not only the cooling capacity of the air conditioner but also the heating factor, and more comprehensive requirements for the energy-saving level of the air conditioner's overall product. Significantly improve the product's access threshold, air conditioner manufacturers in the refrigeration system matching, frequency control technology and other aspects have put forward higher requirements.

          Under the new energy efficiency standards, the market landscape of the air-conditioning industry will undergo profound changes, with the stronger being stronger and the weaker being eliminated.

          The data released by the Ministry of Industry and Information Technology recently showed that the main business income from the production of room air conditioners in China from January to June 2013 was 232.92 billion yuan, a cumulative increase of 17.1% year-on-year and an increase of 9.1 percentage points from the same period of 2012; total profit was 13.69 billion yuan. Yuan, a cumulative increase of 36.2%, an increase of 11.7 percentage points over the same period in 2012.

          At present, China's air-conditioning industry presents Gree, Midea, Haier-led oligopoly. It is understood that in the first half of the three air-conditioning production and internal sales have accounted for nearly 70% of the share, exports accounted for nearly 60%.

          According to industry online statistics, the output of home air conditioners in China in the first half of the year was 6.18547 million units, an increase of 5.22% year-on-year; the cumulative sales volume in the fiscal year was 64.973 million units, an increase of 3.64% year-on-year. Among them, the contribution rate of inverter air conditioner has exceeded the fixed frequency air conditioner, the market share reached 52.54%, and the inverter air conditioner sales and sales increased by 8.3% and 16.2% respectively.

          According to the requirements of the "speed-controllable room air conditioner energy efficiency limit and energy efficiency rating" requirements, China's inverter air conditioner energy efficiency limit increased from the current 3.0 to 3.9, access threshold from 5 to 3, the original 3, Level 4 and 5 air-conditioning will be completely eliminated. Level 1 and 2 air-conditioning will be automatically reduced to Level 2 and Level 3. At the same time, the new standard will also add a level 1 energy efficiency product. Currently, the market availability of Class 4 and 5 energy-efficiency air conditioning products is minimal, but Class 3 energy efficiency products still have a certain amount of inventory. According to the requirements of the new energy efficiency standards, it is expected that more than 30% of the frequency conversion air conditioner products will be out of the game.

          According to information from the second meeting of the China Household Appliance Industry Technology Roadmap Revision Working Group recently held, China's air-conditioning industry plans to achieve a 20% increase in energy efficiency of inverter room air conditioners by 2015 compared with 2010, and by 20% in 2020 compared to 2015. And by 2020, the proportion of inverter air conditioners will increase to 80%.

          In the APF era, the top three industries with congenital advantages in product development, cost control, brand influence, and marketing channels are destined to continue to lead the industry until other competitors are thrown off the runway.

          Refrigerator frequency conversion lead "fresh" technology

          Now consumers' demand for refrigerator products is no longer limited to the category of a€?frozen and frozena€? in the past. Consumers have simply hoped that refrigerators can extend the shelf life of foods and gradually develop the pursuit of food taste, texture, and nutrition. As a result, the technology upgrade and market expansion of high-end refrigerators have been promoted. Frequency conversion, high moisture retention, large capacity, low carbon, and intelligence have become the labels of today's inverter refrigerators.

          In general, the ideal environment for food preservation is to keep it at the optimum lower temperature while maintaining minimal temperature fluctuations while maintaining relative humidity. The inverter refrigerator is the use of inverter compressors, and is equipped with precise computer control and temperature sensing and humidity sensing parts. It creates a fixed humidity and temperature suitable for different food preservation in one or more spaces inside the refrigerator. refrigerator.

          The application of variable frequency compressors can make the refrigerator no longer stop motion as it was in the past, sometimes starting up; it can also extend the shelf life of fresh fruits and vegetables to more than a week. Using an inverter compressor can shorten the ice making speed to 1/2, and the freezing speed can be shortened to 1/3. This powerful rapid freezing capability can make the newly-frozen melted popsicle and frozen dumpling Deterioration due to slow cooling. The intelligent temperature control can control the temperature change inside the refrigerator to the optimum under the condition of the highest operating efficiency, so as to maintain the temperature that is most suitable for preservation.

          According to statistics, the inverter refrigerator has greatly reduced the number of temperature shocks and fluctuations in the refrigerator, nutrition preservation is 3-5 times longer than ordinary refrigerators, and the quick-freezing ability is 20%-30% higher than that of ordinary refrigerators. At the same time, energy consumption is effectively reduced by keeping the low-frequency operation. Above 38%, the noise is greatly reduced.

          Inverter washing machine cut prices to grab the market

          According to statistics from the market research company Yikang, from January to June this year, the penetration rate of frequency conversion washing machines gradually increased. The retail sales share in the first half of the year increased by 6.4 percentage points, and the retail sales share increased by 9.7 percentage points. The share of fixed-frequency washing machines in retail sales and the share of retail sales all showed a year-on-year decline. In the first half of the year, the retail sales share decreased by 6.7 percentage points, and the retail sales share decreased by 10.1 percentage points. The dominant position of fixed-frequency washing machines is being gradually eroded by inverter washing machines.

          According to reports, the key technology of frequency conversion washing machine includes two aspects: First, motor technology, especially brushless DC motor manufacturing technology; Second, the motor control and drive technology. The two technologies applied to washing machines began in the mid-1990s and were dominated by home appliance companies such as Toshiba, Sharp, Panasonic and Hitachi. Koreaa€?s LG and Samsung have applied this technology to high-end washing machines since 2000.

          According to insiders, the a€?frequency conversiona€? of washing machines is relative to a€?fixed frequencya€?. When the definite frequency washing machine starts dehydrating, the rotation speed is directly increased from zero to a certain high rotation speed, and the span is large, which easily leads to large vibration and noise. The application of frequency control technology can make the washing machine soft start, the motor speed gradually increased from zero to the maximum speed, so that the dewatering tube smooth rotation, vibration is extremely small, effectively reduce the noise of the washing machine, the silence effect is obvious. In addition, the frequency conversion washing machine is very efficient in saving water and power. In general, the energy efficiency of the frequency conversion washing machine can be improved by 1/3 compared to the ordinary products, and because the frequency conversion washing machine mostly uses the fuzzy control function, the degree of washing is also greatly improved.

          Although the frequency conversion washing machine has so many advantages, but the frequency conversion washing machine's market share is still lower than the fixed frequency washing machine, the high price is the main reason to prevent the popularity of variable frequency washing machines. It is understood that the same configuration of the washing machine, the frequency of the frequency conversion is higher than the average fixed frequency of 500-1000 yuan. At present, there have been around 2000 yuan in the frequency conversion washing machine, inverter washing machine is gradually reducing the price, put down the body and fixed-frequency washing machines grab the market.
