A few days ago, the project of “Development of Negative 60-degree Working Medium (Ammonia) Tuna Repository†undertaken by Shandong Penglai Jinglu Fisheries Co., Ltd. passed the appraisal of Shandong Provincial Science and Technology Department. The appraisal experts agreed that this technology has filled the domestic gap.
According to reports, "The development of a negative 60-degree working fluid (ammonia) tuna repository" is a project of the Shandong Provincial Science and Technology Development Program. The project uses the “ultra-low temperature†ammonia refrigeration device for refrigerated tuna in the reservoir as an R&D target. A three-stage mixed-cycle ammonia refrigerating system with an intermediate evaporating temperature loop is adopted to achieve not only a stable refrigeration environment with a storage temperature of -60°C but also improved. The cooling conditions in the -30°C preparation room fully satisfied the low temperature demand of tuna cold storage.
At the same time, the three-stage mixed-flow cycle ammonia refrigeration system also uses a serpentine top coil as a cooling device, which solves the problem of the thermal inertia value of the large cold storage maintenance structure and the problem that the gate cannot communicate directly with the external air, and the heat transfer effect is very satisfactory. According to expert analysis, the system is cheaper than the Freon cascade refrigeration system used by most countries in the world. It has a low cost, simple installation process, environmental protection and energy saving, and has completely independent intellectual property rights. Experts believe that the promotion and application of this project will lead to the development of China's tuna fishing industry, transportation industry, processing and catering industry, with significant economic and social benefits.
Jinglu Fishery is a leading company in Penglai City. After winning the Chinese brand name in 2007, the “Jinglu Ocean Shipping†brand products have achieved a significant increase in popularity. The products sell well in more than 20 countries and regions, including Japan, Korea, the European Union, and the United States. Dollars.
