through and exchange energy(heat-recovering system and exhaust heat recovery system). It can separate fresh air and exhaust air completely, avoided
any solvent transmission. The two air cross and counter flow to the exchanger, then fresh
air and exhaust air exchange energy through the metal plate,
collisions between particles in the hot inner region transfer energy to particle
s in the cooler outer region and realize to recycle energy from exhaust air.

LED lighting multiple standards landing standardization is imminent
A few days ago, Guangdong Province issued 11 local standards related to LED lighting, which further advanced the standardization development of the industry. I believe that in the past year, there will be a lot of people in the LED lighting industry industry standards missing, competition disorder, but since this year a standard has emerged, first of all, the new "embedded LED lighting performance requirements" in early January and other national standards Released, the standard is the first national standard for the performance of LED lamps introduced by China. Then, various government departments or industry organizations have successively issued a series of LED lighting standards. Although they are not perfect so far, the industry is still fully standardized. on the way. Guangdong Province issued 58 local standards involving 11 LED lighting projects. In July this year, 58 local standards of Guangdong Province approved by the Guangdong Provincial Quality Supervision Bureau were officially implemented, including 11 LED lighting industries, including Jiangmen, a high-tech enterprise in Jiangmen. City Junda Optoelectronics Technology Co., Ltd. is responsible for the development of LED lighting design standards for elevator lighting (No. DB44/T1336-2014), which was first formulated in the province and even the whole country. It is reported that LED lighting design standards for elevator lighting stipulate lighting standard value, quality, energy saving evaluation, lighting power supply and power distribution indicators, suitable for DC power of rated voltage below 250V and AC below 1000V, can be widely used in office buildings, commercial residential buildings, Lighting systems for passenger elevators and cargo elevators in public places such as shopping malls, stations, subways, and airports. LED explosion-proof lamp lighting related standards landing in July, the National Standards Commission has launched three LED explosion-proof lamp standards development plan, aimed at the development of technical standards, in the field of LED explosion-proof lighting intelligent lighting control, application interface specifications and accelerated detection methods Market, guide industry, and promote innovation. In the international arena, the Zhaga Alliance announced the LED explosion-proof lighting engine interface specifications Book7 and Book8. The new energy efficiency standard for LED explosion-proof lamps developed by the European Union was officially implemented in March 2014. The new products of the LED explosion-proof lamps for sale are mandatory to be labeled with energy. Four LED lighting industry standards introduced the Semiconductor Lighting Technology Evaluation Alliance, China Semiconductor Lighting/LED Industry and Application Alliance released the LED double-ended lamp safety requirements, performance requirements and non-directional self-ballasted LED lamp specification classification and performance requirements in April. There are no standards for the four LED lighting industries. Among them, "Special Classification of Non-Directional Self-ballasted LED Lamps for General Lighting" has been adopted as an important basic standard for the semiconductor lighting industry and has been adopted by the International Electrotechnical Commission of the authoritative international standards organization. This classification standard is proposed for the first time in the world to replace the traditional tiles with the lumens of the lighting effect. As a new concept of dividing the specifications of LED lamps, it can better reflect the characteristics and advantages of LED lamps. In September, the LED driver power supply was included in the 3C compulsory certification category. The National Certification and Accreditation Administration, combined with the implementation experience of the pilot certification implementation rules, comprehensively carried out the adjustment and revision of the specific product compulsory certification implementation rules, in which the LED driver power supply was included in the 3C compulsory certification category, September. It will be implemented on the 1st. The formulation of regional standards is unwilling to lag behind. In view of the fact that national LED standards have not yet been fully covered, many regions in China have begun to work or have developed LED product standards applicable to industries in certain regions. At the end of March this year, a LED company in Jiangxi adopted the Guangdong LED standard and released new technologies and products for the light source LED standard optical components. In terms of standard setting, the Quanzhou LED industry is not far behind, and this work was launched in June this year. Recently, the Institute of Optoelectronics established a standardization research office, and the Quanzhou Standardization Association will work together to develop a Quanzhou LED local quality standard system. The lighting standards are gradually clear. The market will show standardized development in the next three years. The lack of LED standards has been criticized and has adversely affected the healthy development of the industry. Many insiders believe that this is because the development of LED lighting is not mature enough, and many aspects are Development, with the gradual improvement and stability of technology, it is more appropriate to introduce corresponding standards at this time. In this regard, Ye Jianbo, general manager of Hangzhou Zhongheng Paiwei Power Co., Ltd. said: The development time of LED lights is relatively short, and there are technical breakthroughs every year. Many standards apply this year and will not work next year. This is also an important reason for the lack of standards. In addition, different enterprise technologies are not the same as the standard understanding, which also has an impact on the standard inconsistency. For the standardization of the lighting industry, the president of Jingke Electronics (Guangzhou) Co., Ltd., Song Dong, also shared his opinion. There is no standard in the LED lighting industry in the early stage, because many opinions and practices in the industry are not uniform. However, since 2007, LED standards have been slowly programmed, and everyone is following this rule in the field of LED lighting. Only by standardizing things can we grow and develop and survive for a long time. Through the precipitation in recent years, the industry has reached a consensus, especially in the module of light source. Many well-known brands are tending to standardize. In the future, small and medium-sized enterprises in the industry will gradually standardize. Only standards can Get popular. At the same time, Song Dong told reporters: I personally think that the longest time is within three years. All products will become standardized. LED lighting has experienced almost 10 years from 2005 to now, and many technologies have been deposited. We believe that in 2017, all products in the LED lighting industry must be standardized.
