In 2004, Midea cooperated with Toshiba to develop inverter air conditioning technology, and after 5 years of technology accumulation and precipitation, on September 1, 08, it launched five series of more than 10 new DC inverter air conditioners in one fell swoop. According to Zhang Zhiguo, spokesman and marketing director of Midea Air Conditioning, the five series of DC inverter air conditioning products launched by Midea Air Conditioning all use 180-degree sine wave vector control technology, among which Midea Galaxy C180 is the first inverter air conditioner energy-saving certification certificate from China Quality Certification Center (CQC), with the certificate number CQC08701026100. The seasonal energy efficiency ratio is high, and the operating frequency is as low as 15 Hz.
In the face of individual brands to buy inverter to see 15 hertz publicity, Zhang Zhiguo said that the United States inverter air conditioner 08 years on the market at the beginning of the launch of the product Galaxy C180 with a running frequency of 15 Hz, as the flagship product of the full DC inverter Galaxy C180, in the energy efficiency ratio, function, appearance have achieved innovative technological breakthroughs. Combining innovative features with an ultra-luxurious look, the Galaxy C180 has become a symbol of high quality of life. Zhang Zhiguo also introduced that the operating frequency is an important standard for inverter air conditioning, but inverter is the system technology from compressors, control chips to capacitors and other related fields, and what links all technologies together is control, and now the top is 180 sine wave vector control.
All DC inverter air conditioners in the United States use 180 degree sine wave control technology, is the only one in the domestic air conditioning industry, although some brands claim to master the sine wave air conditioning technology, but the market sells more than 95 or 120 degrees square wave.
The world's first inverter air conditioner was successfully developed by Toshiba in Japan in 1981, and the current share of DC inverter air conditioner in Japan has been as high as 100. But it is in this market with a very high technical threshold and quality threshold, starting from 04, the Toshiba brand DC inverter air conditioner manufactured by Midea Air Conditioning Shunde Factory has won the Japan Energy Conservation Award for 4 consecutive years, with a cumulative sales of more than 1 million sets, and has been recognized by more than 1 million families in Japan. 180-degree sine wave control technology is a must-have for high-end inverter air conditioners.
As the inventor of the world's first inverter air conditioner and the first dual-rotor inverter air conditioner, Toshiba has maintained its technological leadership as the originator of inverter. Midea air conditioning has always been a representative of China's technological innovation enterprises. Deng Mingyi, You Bin and other Midea air-conditioning engineers have successively served as deputies to the National People's Congress and winners of the May Day Labor Medal, creating a precedent for China's home appliance industry technology research and development personnel to win the highest national honor.
Inverter air conditioner is not good mainly because of the compressor, simply put, inverter air conditioner is to add a frequency converter to the structure of conventional air conditioning. The compressor is the heart of the air conditioner, and its speed directly affects the efficiency of the air conditioner, and the operating speed of the compressor, the heart of the air conditioner, is adjusted, so as to achieve a reasonable use of energy. When purchasing inverter air conditioners, we should start from brand awareness, reputation and the overall R&D strength of the enterprise, shop around, and then shoot when it is time to shoot.
In recent years, the sales of inverter air conditioners in the home appliance market have been hot, and the topic of whether inverter air conditioners are good or not is also diverse, and it is difficult to distinguish between true and false, of course, while people are competing to buy inverter air conditioners, there are still many rational consumers who are waiting: Is inverter air conditioning good? Editor's Recommendation: >>>More
There are many kinds of air conditioning faults, and when encountering faults, learn how to detect them first, and then determine the fault to solve them. >>>More
Will convert the frequency by itself.
Inverter air conditioning. basic structure and refrigeration principle. >>>More
I want to save more power on the basis of frequency conversion and keep the temperature constant. Since the inverter air conditioner adopts non-stop temperature control, it can effectively avoid the inaccurate control of the room temperature by the compressor starting and stopping, and there is no longer the discomfort of hot and cold. Generally, inverter air conditioners can control the temperature fluctuation within degrees, which can completely keep the temperature constant and improve the accurate control of temperature. >>>More
