Sonyo Refrigeration (Dalian) Co., Ltd. officially changes its name and the first domestic medium and low temperature Stirling generator unit officially comes off the production line

On July 19th, Sonyo Refrigeration (Dalian) Co., Ltd., a company established 31 years ago under the Bingshan Group, held a ceremony to mark its name change and the launch of China's first domestic low-medium temperature Stirling generator set. The company officially changed its name from "Panasonic Appliances Air-Conditioning and Refrigerantion (Dalian) Co., Ltd." to "Sonyo Refrigeration (Dalian) Co., Ltd." Bingshan Group Vice President Fan Wen and other leaders attended the name change ceremony.

After years of development, as a leading enterprise in China's air conditioning, environmental, industrial refrigeration and heating fields, Songyang Refrigeration has accelerated the adjustment of its product structure and focused on important sub-markets such as flue gas waste heat recovery to save energy and reduce emissions. On the 19th, as a wholly-owned subsidiary of the Bingshan Group, Songyang Refrigeration took an important step in its transformation and upgrading: the domestically-produced, first low-medium temperature Stirling generator set, independently researched and manufactured, was officially launched and started for the first time.

The low-medium temperature Stirling generator set can utilize waste heat from flue gas in multiple industries such as steel, chemical, metallurgical, and coking, realizing the recovery of low-medium temperature energy resources and directly converting them into electricity resources needed by enterprises. It is an energy-saving and emission-reduction product urgently needed by the market.

The low-medium temperature Stirling generator set developed by Sonyo Refrigeration has overcome the difficulties in materials and precision manufacturing processes, solving key issues such as engine operation lubrication and sealing. With the support of intelligent control technology, it achieves a comprehensive power generation efficiency of about 30%, reaching a domestically pioneering and internationally leading level, filling the gap in the industry for low-medium temperature flue gas Stirling generator sets.

The research and development and market launch of the low-medium temperature Stirling generator set enables Sonyo Refrigeration to improve its waste heat utilization product matrix based on absorption-type energy-saving cold and heat products, achieving a comprehensive energy solution of cold, heat, and electricity. This will undoubtedly enhance the competitiveness and market development capabilities of Sonyo Refrigeration products, laying a solid foundation for the development of the company's energy conservation and emission reduction initiatives.
