Inverter compressor technology development trend From single-frequency air conditioners to inverter air conditioners, the air-conditioning industry has taken a big step. The debate between DC inverters and Digital Vortex compressors has been a longstanding and fiercest industry. The compressor technology used to regulate the capacity so far has really dominated the market with only variable frequency and digital vortex technology. Two completely different approaches were used to adjust the capacity of the compressor, which led to differences in many aspects. What are the development trends of inverter compressors in the future?

Energy conservation and emission reduction have become the new trend and new trend of global home appliance development. The air-conditioner, which has been known as the electric tiger, has become a powerful weapon for winning the market. As the core compressor supplier of air conditioners, GMCC Meizhi has helped air conditioning climb the pinnacle of energy conservation and emission reduction with its innovative and innovative energy-saving technologies.

In the central air-conditioning market, DC inverter multi-unit central air-conditioners represented by Daikin are the most involved in manufacturing, and the competition is fiercest. The brands include Hitachi, Mitsubishi Electric, Mitsubishi Heavy Industries, Mitsubishi Heavy Industries Haier, Toshiba, and Haier. The rate of more than 80% is the absolute main force of the current multi-line market. The digital vortex central air conditioner represented by Samsung, the manufacturer is basically the United States and South Korean brands as the mainstream, digital vortex multi-connected Although in all aspects of technical indicators as much as the variable frequency multi-line, but due to digital vortex into the Chinese market The time was late, and due to the monopoly of compressor technology, this kind of product has kept high in terms of cost, so there is still a gap between the degree of market recognition and market competitiveness and variable frequency multi-connection.

The official sales of Digital Vortex Online in China can be said to have broken the long-term dominance of multi-line inverters. However, from the perspective of market demand, digital vortex technology has not been widely understood and understood by the market. Therefore, there is a certain resistance in the promotion of the market. Enterprises need to spend more energy to actively guide consumers and promote the market. In the Chinese market, since 2002, Emerson Climate Technologies has successively reached strategic cooperation relationships with eight famous air-conditioning manufacturers including Midea, Gree, McQuay, Mitsubishi Heavy Industries Haier, Hualing and Shinco, effectively promoting digital vortex technology and The application of the product in the early Chinese market.

Digital Vortex multi-connections show almost no sign of any significant growth compared to variable frequency multi-connections. The competition in the variable-frequency multi-play group market has been fierce enough, and when any company in which it was forced to face rivals such as Daikin, more companies began to use digital vortex units to express their respective variable flow units for refrigerants. The desire of the market. As a result, it was once seen that the digital vortex generator market has an unprecedented number of people. However, in 2006 and 2007, when these brands had vigorously entered the digital scroll market, the only impression left on the industry so far was their gorgeous debut and they disappeared afterwards. Even some of the domestic brands that have already formed a certain sales scale for digital scroll products, such as Gree, Midea, and other original digital vortex fans, have almost abandoned digital vortex.

In contrast, it must be said that Digital Scroll products currently do not have a clear competitive advantage, especially in the very strong backing of inverter compressor multi-connected groups, the digital scroll unit market can now be used almost to describe. From the perspective of the basic elements of marketing, the lower degree of awareness and acceptance of channels is the biggest disadvantage of digital vortex products compared to competitive products; apart from being significantly higher than water-cooled screws and modular machines, the price level of digital vortex products Even higher than the frequency conversion multi-product. The price of the digital scroll compressor is the sum of the price of the inverter compressor plus the control system. Obviously, in the current market is not ripe, it seems that the reason for supporting this expensive is not enough, and some people in the industry even bluntly pointed out that the only way out of digital vortex is to cut prices; even if the digital vortex product has its own unique features and Advantages, at least for the moment, these advantages do not constitute the reasons for their inevitable leading competitors, and the disadvantages of the slow technical renewal and long lead-times of Digital Scroll products have been criticized by the industry. In addition, in fact, Digital Scroll Technology itself The promotion in the Chinese market is still in a weak position. Initially, the promotion of digital vortex focuses on the level of design institutes. Now it seems that there is no complementary channel for promotion and the promotion of real estate developers can be described as a failure.
