A gimmick or a real effort to do

the past two years, with the frequency implementation of national standards for energy efficiency and home appliances, and other policies to promote energy-saving PWM, inverter air conditioner with energy-efficient, high-comfort advantages of a vast number of consumers to gain further recognition popularization greatly accelerate the speed. In particular, in 2010, inverter air conditioner in the market's performance can be described as wind and water. According to the National Information Center data show that the first quarter of 2010, inverter air conditioner market share has increased to 18.18% from last year's 30.38%, and this year the ratio will be close to or exceed 40%.

the face of enormous market opportunities, Midea, Gree, Hisense, Haier, Oaks and other co-leader in domestic air conditioning market, aiming for the inverter air conditioner. Price war, the concept of war, the service launched war after another, in which some companies also dished out to achieve Is this a gimmick or a factory-made products, the technological upgrading of air conditioning? Hertz air-conditioned low-technology and the practical effects of what impact? With these questions,

theory, low frequency operation means that the inverter air conditioner compressor can run a wider frequency range, namely, the achievement of the air-conditioned non-stop operation, thus reducing the indoor temperature fluctuations, to a greater extent increased user comfort, and similar to constant speed to avoid air-conditioning downtime and improve the operating efficiency of air conditioning.

inverter controller according to the National Sub-Committee Vice Chairman Dr. Wang Zhigang, due to the lack of standard definition, currently on the market within the meaning of The first level refers to the variable frequency controller can achieve the lowest frequency, in theory, the lowest frequency is not limited, to The second level is the operating frequency of inverter air conditioner compressor, the compressor can reach the current minimum frequency frequency of 4 Hz. The third level is the entire air conditioning system, the user's environment, air-conditioning can be achieved using the lowest operating frequency. Today, air-conditioning can be achieved under normal operating conditions the minimum frequency is 10Hz or so.

defined three levels of analysis of great significance. Some manufacturers use low-frequency operation of technology is the concept of ambiguity, for consumers to make the wrong guidance. A company has claimed that the inverter air conditioner can be realized, The experts said the move is really altered the idea, just the operation of variable frequency controller can achieve the frequency shift received air-conditioning compressor. From a technical perspective, the air conditioning load on the machine in accordance with 1 Hz and stable operation of the compressor could not be achieved.

present,MBT schuhe preise, the real power input of 1 Hz can be achieved only compressor motor coil heating, such as the United States and the inverter air conditioner in the country's first master of the bad weather in the winter when the heating front starts to be in the best working conditions, improve the heating capacity, and the protection of the compressor, and improve their life.

In addition, operating frequency of inverter air conditioner compressor, 4 Hz low-frequency inverter to run air-conditioning technology has reached a global low-frequency limit of operation. It is understood that dual-mode Hisense inverter air conditioner has achieved ultra-broadband operation of 4-150 Hz, and is only carried out in public demonstration of air-conditioning business.

divided according to the industry, the fourth generation of inverter air conditioner has been realized from 10 Hz to 150 Hz operating frequency range, you can achieve balance between supply and demand of cold room, to provide users more comfortable using the results . The operating frequency below 10 Hz so-called fifth-generation inverter air conditioner, the user is not satisfactory practical significance. do Rui Bo gimmick also true power tube Husband

Wang Chih-kang said the user in the actual use of air conditioning, it is basically the following will not need to 10Hz, such as the most commonly used 1.5 inverter air conditioner, when the outdoor environment is 35 ℃, can operate at 30Hz frequency to ensure stable operation of air conditioning. Even the somewhat less at 27 ℃ under open air, does not need to run to 10Hz or less. Wang Chih-kang that, air conditioner market is still early in the competition, is facing from the development to the mature stage of the transition barrier, there is the inevitable phenomenon of excessive competition. Low-frequency operation of domestic air-conditioning technology, business promotion efforts, to some extent can be seen as an opportunity to gimmicks to attract consumers, although the actual technology, but did not have its uses.

However, technological upgrading of air conditioning products to promote the development of the industry, as well as independent research and development of domestic air conditioning core technology strengths, and can not thus be denied. That the air conditioning industry Shen Jian, a long time in the future, technology companies around the contest will become the focus of competition inverter air conditioner. Only breakthroughs in core technology to increase the product cost, and ultimately product differentiation and industrial upgrading.
