Ge Fengliang, vice president of China Household Electrical Appliances Research Institute, Liu Junjie, professor and doctoral supervisor of the School of Environmental Science and Engineering of Tianjin University, Xiao Peng, deputy director of China Household Electrical Appliances Testing Institute and deputy director of the certification center, Song Liqiang, director of the household electrical appliance testing center of China Academy of Household Appliances (Beijing) Testing and Certification Co., Ltd., Wang Yingying, chief engineer, Song Shanshan, executive deputy secretary general of the Electrical and Electronic Branch of China Standardization Association, Sun Peng, head of the Light Industry Standardization Institute and editor-in-chief of the journal "Light Industry Standards and Quality", and Zhang Rui, editor-in-chief of the journal "Household Appliance Science and Technology". Yang Zheng, a researcher at the National Household Appliance Industry Information Center, and other experts and scholars discussed the development opportunities of the range hood industry and explored the development direction of core science and technology with representatives of range hood companies such as Midea Kitchen and Bathroom Appliances, Haier Smart Kitchen, Robam Appliances, Jingwei Technology, Wanhe, Aucma Life Appliances, Wanjiale and other range hood companies, as well as industry media. Li Jichao, deputy director of the Household Appliance Testing Center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., presided over the forum.
Ge Fengliang, vice president of China Household Electrical Appliances Research Institute
Ge Fengliang, vice president of China Household Electrical Appliances Research Institute, pointed out in his speech that the overall kitchen and bathroom appliances market will rebound in 2023, with the market size of range hoods reaching 31.3 billion yuan, a year-on-year increase of 6.5%. At the same time, the trend of two-level differentiation of consumption is obvious, reflecting the pursuit of different consumers for quality-price ratio and quality life. Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., together with a number of enterprises, has jointly formulated the T/CAS848-2024 "Technical Specification for the Grading and Evaluation of the Smoke Purification Effect of Range Hoods", which simulates the scenarios used by users from the perspective of users, and provides a test basis for the evaluation of the smoke purification ability of range hoods by detecting the concentration of PM2.5 at different locations.
Liu Junjie, professor and doctoral supervisor of the School of Environmental Science and Engineering, Tianjin University
Liu Junjie, professor and doctoral supervisor of the School of Environmental Science and Engineering of Tianjin University, pointed out in his special speech "CFD Simulation and PIV Experimental Research on Fume Escape Characteristics and Capture Performance" that compared with the Chinese and Western particulate matter emission rules, the average emission concentration of particulate matter in Chinese kitchens is almost 35 times that of the West, and the cooking method of Chinese food is mostly stir-frying, and the cooking temperature is higher, which causes the characteristics of higher concentration of pollutants in Chinese cooking and wider particle size distribution. To this end, Professor Liu focused on the emission characteristics of Chinese cooking, the evaluation method of the smoke exhaust capacity of the range hood, and the high-efficiency capture technology of the range hood, and carried out the research and development and performance testing of the high-efficiency capture range hood, and established a PIV measurement method system suitable for the study of flow field and concentration field in the cooking area.
Yang Zheng, a researcher at the National Household Appliance Industry Information Center
Yang Zheng, a researcher at the National Household Appliance Industry Information Center, analyzed the trend of the range hood industry in 2024. According to Yang Zheng, in the first quarter of this year, kitchen appliances rebounded slightly as a whole, and range hoods also maintained a growth pace, with retail sales of 5.8 billion yuan, a year-on-year growth rate of 0.9%. Various manufacturers have increased the change of suction and exhaust effect and appearance form, and the trend of large air volume and large wind pressure continues, and 25m?/min and above have become a new position for new product competition. With the change of smoking mode, the appearance of the range hood has also changed, and the new range hood not only improves the suction and exhaust effect, but also takes into account the cleanliness and beauty, and the white and light color matching sets have increased. With the gradual implementation of the trade-in policy this year, both new and new opportunities are improving.
Wang Yingying, chief engineer of the household electrical appliance testing center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd
With the upgrading of consumption and the improvement of consumers' demand for quality life and healthy life, the upgrading of household appliances is showing a trend of high-end development. The development of high quality is inseparable from high standards of testing and certification, Wang Yingying, chief engineer of the household electrical appliance testing center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., introduced the current range hood market self-cleaning, non-dismantling and washing, smoke purification effect grading and other time-sensitive hot spot certification.
The grading certification of smoke purification effect is based on the group standard of T/CAS848-2024 "Technical Specification for Grading and Evaluation of Smoke Purification Effect of Range Hood", and Wang Yingying gave a detailed interpretation of the standard content and test methods. There are 16 participating enterprises in this standard, which is the first standard for range hood smoke purification jointly drafted by the industry. Under the condition of fully considering the user's use scenario, the range hood is run to the working air volume state, and the concentration of fixed-point oily smoke particles in the breathing area and the concentration of oily smoke particulate matter at the fixed-point environment are tested, and the smoke purification capacity of the rangehood is judged according to these two indicators.
Xiao Peng, deputy director of China Household Electrical Appliances Testing Institute and deputy director of the certification center
Xiao Peng, deputy director of China Household Electrical Appliances Testing Institute and deputy director of the certification center, introduced the value of voluntary certification to enterprises. Zhongjiayuan (Beijing) Testing and Certification Co., Ltd. is a certification service organization approved by the CNCA, combining its own advantages and capabilities to create an integrated comprehensive service system of "standards, testing and certification". Transforming certification evaluation methods with standards and determining testing standards and means can further improve the efficiency of product certification and convey trust to consumers in a timely manner.
