Home Appliances Upstream Transformation and Upgrade

"Now consumers are very professional, will always ask me what brand of compressor equipped with a refrigerator." Appliance stores, a refrigerator salesman told reporters. Indeed, rational consumption has become a trend. Consumers have simply looked at the appearance, compared to the price to the overall comparison of the overall performance of home appliances, compressors, motors, controllers, insulation materials... These terms are for the average consumer. It is no longer strange to say. In order to cater to consumers, home appliance stores can often see refrigerators, air conditioners, and washing machines displayed by “anatomy”. Machine manufacturers and distributors hope that in this way, consumers can intuitively understand the brand and internal assembly structure of major components of home appliances. .

In recent years, with the rapid development of China's home appliance industry, accessory manufacturers have continuously increased their investment and comprehensively improved their capacity from the aspects of production capacity, quality and technology. The technological advancement of compressors, motors, controllers, molds, and various raw materials has also driven the upgrading and transformation of home appliance products. Some major home appliance companies such as Midea and Gree have strengthened their layout in upstream core technology areas such as compressors and motors, and controlled the design and production of core components to strengthen their technological competitiveness and control production costs.

According to the “Electrical” magazine statistics, from January to June 2011, the production and sales volume of refrigerator compressors in China was around 60 million units, and the annual production capacity of the entire industry was more than 140 million units. The COP value of the refrigerator compressor is continuously updated, the volume is getting smaller and smaller, and the weight is getting lighter. From the perspective of the average production level of the industry, compared with the early 1990s, the energy consumption of refrigerator compressors is reduced by more than 60%, and the production process is also more advanced. It is understood that at present, improving energy efficiency and miniaturization are the two major focuses of technology research and development in the field of refrigerator compressors. Embraco's EMD series of highly efficient mini-series compressors has reached a COP of 2.1. Huangshi Dongbei L series environmental protection energy-saving materials refrigerator compressor won the second prize of national scientific and technological progress. The weight of each Dongbei L series compressor is only 7.5kg, which is 3.5kg less than that of the common model, and the volume is reduced by 20%. The material saving is 31.8%, the maximum COP value is 2.03, and the noise value is less than 35.6dB (A). In 2011, Dongbei has put newer H-Series compressors on the market. In terms of miniaturization of the compressor, the weight of the refrigerator compressor with a COP value of 1.6 is 5 kg.

The theoretical total annual production capacity of the air-conditioning compressor industry has exceeded 120 million units, but as far as the current situation is concerned, this production capacity is still unable to meet the procurement requirements for air conditioner production. In 2011, the new production capacity of air-conditioning compressors was mainly based on high-efficiency constant-speed compressors and variable-frequency compressors. In 2011, Guangdong Meizhi added three inverter compressor production lines, and its annual production capacity is expected to reach 55 million units in 2015. Shanghai Hitachi's annual production capacity also expanded to 18 million units in 2011. The capacity of Zhuhai Lingda Compressor Co., Ltd., which mainly supplies Gree Electric Appliances and air-conditioners, has exceeded 16 million units. In addition, manufacturers of air-conditioner compressors such as Panasonic Wanbao Compressor, Mitsubishi Electric, China Resources Sanyo, and Xi'an Qingan also have production expansion plans, new production line projects launched, and other expansion plans.

The driving motor is the core component of the washing machine and directly relates to the hard index such as washing rate, noise value, and energy efficiency level of the washing machine. Many washing machine manufacturers have invested in the construction of motor production lines, such as Haiqi Electric's Zhangqiu Haier Motor Co., the United States's Welling Motor and Wuxi Little Swan Huayin Electric Co., Ltd. and so on. In 2011, washing machine companies focused on promoting DC brushless motors and three-phase inverter motors with better performance. The development of such new motors has become a hot topic.

At the same time, various raw materials, components, molds, and manufacturing equipment industries in the upper reaches of the industrial chain are rapidly developing. In the field of home appliance production, technical R&D personnel are very sensitive to various new materials and new processes and are actively experimenting with various home appliances.

This reporter learned that in order to demonstrate the latest scientific and technological achievements in the upstream parts and components raw materials field, it provides a platform for communication and exchange between the upper and lower reaches of the home appliance production chain. The China Household Electrical Appliances Association will set up a raw material exhibition area for accessories at the China Household Appliances Expo held each time. The “2012 China Household Appliances Expo” to be held in Shanghai New International Exhibition Center in March 2012 is to set up a special exhibition for home appliances, spare parts and supporting services to better serve the industry transformation and upgrading. Judging from the current situation, the sub-exhibition of the raw materials for household electrical appliance parts and accessories is highly concerned by the relevant companies in the appliance industry chain. According to the reporter's understanding, many companies are preparing to showcase their new products and technologies through this platform. Currently, Shanghai Hitachi Electric Appliance Co., Ltd., Guangdong Meizhi Refrigeration Equipment Co., Ltd., Beijing Embraco Snowflake Compressor Co., Ltd., Huangshi Dongbei Electromechanical Group Co., Ltd., Gaxibeila Compressor Co., Ltd., and Wuxi Hejing Technology Co., Ltd. Companies such as Hangzhou Hotwell Electromechanical Co., Ltd., Suzhou Ruitaike Electromechanical Co., Ltd. and other companies have already confirmed their participation. Shanghai Hitachi and Guangdong Meizhi exhibit more than 200 square meters of exhibition space, more than double the previous session.

In an interview with reporters, Zhu Jun, deputy secretary-general of the China Household Electrical Appliances Association, said: "Since 1992, the China Household Appliances Expo has been successfully held for 10 sessions. It has witnessed the vigorous development of China's home appliance industry. Each point of progress has played an active role in the development of the industry. The 2012 China Household Appliances Expo will be a good platform for more parts and components companies to have the opportunity to display their new products and new technologies, and to help the whole machine and supporting enterprises to build bridges and promote The home appliance industry is developing healthily."
