The long-awaited SNEC exhibition finally debuted on August 8, welcoming industry professionals from all over the world. On August 8, 2020, the 14th International Solar Photovoltaic and Smart Energy (Shanghai) Exhibition and Forum in 2020 was grandly opened at Shanghai New International Expo Center, China.

Hebei Daorong New Energy Technology Co., Ltd. (hereinafter referred to as Daorong New Energy) brought the core component of solar energy industrial heat utilization—medium-temperature heat collector tube to the exhibition. Facing the epidemic since the beginning of the year, the global economy has suffered a great impact, and colleagues in the solar energy industry have responded actively. Daorong New Energy, as a leader in the field of medium-temperature "Solar Thermal +" clean heating, has proactively entered the solar medium-temperature market and promoted the marketization of the industry.

Daorong New Energy was registered and established in December 2017. Since its establishment, Daorong has been laid out in accordance with the development of national industries. Now it has become a high-tech enterprise integrating R&D, design, manufacturing and sales of solar thermal products, focusing on the development and utilization of “Solar Thermal +” clean energy. It has obtained a series of certifications such as ISO9001, ISO14001, ISO18001, and a number of innovation awards. It has applied for more than 160 patents, including more than 20 invention patents.

Daorong New Energy has created a medium-temperature "Solar Thermal +" model, which has come from behind and achieved good results in just a few years. It has not only become a leading solar thermal enterprise in Xingtai, Hebei, but also achieved great success in the project of using "Solar Thermal +" clean energy for rural clean energy heating renovation, leading the Hebei medium-temperature " Solar Thermal +" market.

Daorong New Energy automated production line has the advantages of large-scale production capacity and high degree of automation. The heat collector tube produced by it is of high quality and has a life span of 25 years. In addition, Daorong New Energy has independently developed a 2.5m opening coupling photovoltaic power generation trough type medium-temperature solar collector, and this collector can provide 100-250℃ steam, heat transfer oil, high temperature hot water, hot air and other medium and high temperature heating modes.

Daorong New Energy's chairman, Mr. Xue Daorong, pointed out " In order to verify its performance, Daorong New Energy built a 500m2 trough medium-temperature solar heat collection system coupled with a ground-source and air-source heat pump demonstration system in 2018, and used for the combined cooling and heating of the company's 20,000m2 plant, initiating the combined cooling and heating mode of China's medium-temperature solar energy coupled dual-source heat pump system for industrial plants. This should be the first domestic demonstration project of medium-temperature "Solar Thermal +". After the measurement and calculation during a heating season, the system can significantly save energy, reduce costs, and reduce consumption for industrial plants. It has proved that its technology is feasible and economical. Based on this, Daorong New Energy is promoting the standardized medium-temperature "Solar Thermal +" clean energy heating system according to local conditions. It is expected that in 2020, it will complete the application of medium-temperature heating with 1 million square meters of heat collection area".

Under the new situation, the medium-temperature "Solar Thermal +" will surely make great breakthroughs in the medium-temperature application field with its stable clean energy supply characteristics and future technologies that can reduce costs and increase efficiency, and enter a period of real industrial development. Daorong New Energy will continue to move forward with the unchanging original intention, professional and honest quality, and conscientious and innovative spirit.
