Policy is not in place, low market awareness, good and bad products. The establishment of CRAA certification Union, heat pump water heater business Baotuan seeking development On October 30, 2008, a goal is to promote the healthy development of heat pump water heater industry "heat pump water heater CRAA Union" was established in Beijing. The alliance is made up of seven companies that have been CRAA certified by the China Refrigeration and Air-Conditioning Industry Association voluntarily joined. At the same time, alliance enterprises signed the alliance declaration with the theme of "Adhering to the Scientific Outlook on Development and Promoting the Development of Heat Pump Water Heaters in the Field of Energy Saving and Environmental Protection", expressing their willingness to actively play their part in the alliance under the banner of the alliance and work together for China Heat pump water heater market, the healthy and sustainable development to make its own contribution. National Development and Reform Commission, Ministry of Science and Technology, Ministry of Construction, Machinery Industry Federation and the State Certification and Accreditation Administration Committee and other ministries and leaders attended the meeting and delivered speeches. The establishment of coalition is the development of the industry needs At present, the seven member units participating in the coalition, the United States and Guangdong Commercial Air Conditioning Equipment Co., Ltd., Beijing Tongfang Clean Technology Co., Ltd., Zhejiang Zhengli Electric Co., Ltd., both mainstream brands to enter, but also joined SMEs . "'Heat pump hot water machine CRAA certification Union' will also advocate more outstanding enterprises to join, take the corresponding responsibility, and enjoy the appropriate benefits, the industry level up as soon as possible." Beijing Quality Certification Center Co., Ltd. General Manager Tian Xudong said. According to reports, CRAA certification is China Refrigeration and Air-Conditioning Industry Association in the implementation of the product performance certification in 2004 by the China Refrigeration and Air Conditioning Industry Association and Hefei General Hospital jointly established in the Beijing Quality Certification Center Co., Ltd., CRAA certification as the implementation of Agencies, there are already 102 companies have achieved CRAA certification.

April 2008, the national standardization of refrigeration and air conditioning equipment Technical Committee promulgated the national commercial heat pump water heater (GB / T21362-2008). Then, in June 2008, Beijing Zhongzhengong Quality Certification Center formulated the heat pump water heater certification rules according to the national standards and started to implement CRAA certification in the heat pump water heater industry. According to reports, with the heat pump hot water CRAA certification alliances and the development of the industry's growth, China Refrigeration and Air Conditioning Industry Association will consider the alliance on the basis of the establishment of heat pump hot water machine Professional Committee, as a national industry organization. With the influence and resources of China Refrigeration and Air-Conditioning Industry Association, alliance members will make statistics and analysis in the industry data, formulate the standards of the association, obtain the latest domestic and foreign technical and market information, participate in the exhibitions and expeditions, periodical magazines, sharing of technical materials, etc. For more resources. It is understood that through the CRAA certification, consumers can more easily identify the performance level of enterprise products. The enterprises in CRAA heat pump water heater alliance strive to be an industry example and advocate industry enterprises to strengthen their self-discipline. Through the leading role of alliance members, the products of industry enterprises will be improved in product quality and integrity, and users' confidence in heat pump hot water machine products will be established. CRAA heat pump water heater Union will also be through technological exchanges, etc., to jointly promote the industry's technological innovation and technological progress. "Heat pump water heater industry is developing rapidly, but still a new field. It meets the national environmental protection, energy-saving industrial policy requirements, the need for national policy support. At present, many enterprises, product quality varies greatly, the need for norms and guidance, the establishment of this Alliance is the development of the industry needs.
