Energy efficiency, comfort, operational reliability, precise control, technical innovation and breakthrough multi-frequency units leave this way, the fifth generation of Gree DC inverter multi-unit GMV5S series with 105 patents, a comprehensive solution to multi-unit frequency core technical issues, a number of technical indicators have reached the international advanced level, or leading, multi-line aspirations to the top of the inverter technology. Thanks to its frequency multi-unit installation, design simplicity, as well as independent control and billing household convenience, has become the first choice for most of the commercial and residential projects central air-conditioning system. Statistics show: 2012, the national frequency multi-unit central air conditioner market capacity of 207 billion yuan, while only a single frequency multi-unit product will occupy more than one-third of the country's central air-conditioning market share, and central air conditioning unit products more than ten kinds of forms, indicating that frequency multi-unit central air-conditioning industry has become China's most important form of the unit. In the past, foreign brands as multi-line master the core technology, once firmly occupy the absolute share of China's multi-unit market. However, the domestic central air-conditioning business to be outdone, through unremitting efforts, finally break the monopoly foreign technology, the market share of the Chinese piece of cake. Among them, the Gree Electric is one of the best. After several years of accumulation, from the smooth development of the first generation of multi-frequency line of products so far, Gree has completely independent intellectual property rights owned multi-unit upgrades to the fifth generation --GMV5S. Thanks to the advanced DC inverter technology, optimized design and precision air-conditioning system of intelligent control technology, Gree GMV5S DC inverter multi-unit more energy efficient, comprehensive energy efficiency up to 6.8, 89% higher energy efficiency than the national . Gree GMV5S series once again to achieve a breakthrough in technology innovation, leading the industry in the new round of technology upgrades tide. Frequency is a multi-unit trailer and more air-conditioning systems, control parameters and more complex data interaction, the reliability and speed of communication is the key technology. The industry's major brands using HOMEBUS or 485 bus communication technology, Gree GMV5S CAN bus communication technology, is the industry's first application in the field of automotive and military technology to a multi-line bus. Higher reliability, communication speed by 100%, to achieve a drag eighty single refrigeration system for the industry the most. According to the system load changes, GMV5S series inverter multi-line evaporation system can automatically adjust the temperature, which makes the ability to "on-demand output." Unit comes with two kinds of energy-saving operation mode for the user to choose from to meet city requirements for peak load shifting and brownouts. After running the power-saving mode, the unit can be maximum 20% power savings. In addition, GMV5S series inverter multi online on noise control performance even more remarkable. Through the duct to optimize the design, use and efficient means of three-dimensional axial flow fan, comes with 12 kinds of silent mode, the unit out of the machine can be as low as 45 db minimum noise. Unit also uses environmentally friendly R410A refrigerant designed to maximize the protection of the environment. Industry experts said: frequency multi-unit has become China's central air-conditioning industry, the largest market share and fastest growing products. Domestic and foreign central air conditioning companies in recent years have increased the frequency for multi-line input and resource-oriented products. Especially since the second half of 2012, foreign companies have launched their own new generation of multi-unit frequency products, which become the focus of energy efficiency demands. Gree air conditioning units GMV5S new generation of multi-frequency products in domestic and foreign enterprises with a new round of competition in the multi-line products, not only in the energy efficiency of the data done industry-leading technology applications simultaneously on multi-frequency units also have innovation For, we can see, Gree air conditioning has to stand on top of the central frequency of multi-unit technology.
