Foxconn lithium battery explosion-proof cold storage project construction plan

　　Project category: lithium battery low temperature explosion-proof warehouse project

　　Project period: 35 days

　　Cooperation year: 2020, 2021

　　Acceptance date: July, September 2020, January 2021

　　Project requirements: Foxconn Technology Group’s 2,400 square meters battery explosion-proof cold storage project, constructed by our company Haoshuang Refrigeration, mainly used for battery storage. This explosion-proof cold storage project is divided into Shenzhen warehouse, Zhengzhou warehouse, and Taiyuan warehouse. All three warehouses are explosion-proof cold storage (explosion-proof design inside the warehouse); the ground insulation adopts SBS waterproof layer + 100mmXPS extruded board + PE air barrier film + 200*200mm steel grid + 100mm reinforced concrete (grade C30) + anti-static floor; management needs to meet centralized control; under the premise of controlling costs, select high-efficiency and energy-saving solutions and equipment; meet the main requirements of the URS file.

　　Project Overview:

　　(1) Shenzhen warehouse consists of three rooms with a total area of ​​600 square meters and a net height of 8 meters (divided into battery warehouse 1, battery warehouse 2, and battery warehouse 3, each with an area of ​​200 square meters); Zhengzhou warehouse consists of one room with a total area of ​​1,375 square meters and a net height of 6 meters; Taiyuan warehouse consists of two rooms with a total area of ​​446 square meters and a net height of 3 meters (divided into battery warehouse 1 with an area of ​​228 square meters and battery warehouse 2 with an area of ​​218 square meters). The cold storage temperatures of the three warehouses are 10-15℃ respectively.

　　(2) Each cold storage in Shenzhen and Taiyuan adopts two-in-one cold storage; Zhengzhou adopts a three-in-one cold storage system. The refrigeration compressor of this project uses the internationally renowned brand German Bitzer piston compressor. The unit has a large cooling capacity, high cost performance, safety and reliability. The explosion-proof special high-efficiency air cooler configured in the cold storage enables forced convection of air in the warehouse and a fast cooling speed. The air coolers all use corrugated aluminum fins and high-quality copper tubes, with high heat exchange efficiency and green energy saving. The air cooler adopts a new design concept, applies multiple patented technologies, uses small temperature difference heat transfer technology, is equipped with explosion-proof fan motor, thermal expansion valve liquid supply mode, and runs stably with low noise.

　　(3) The temperature control system adopts Siemens imported fully automatic temperature control system, which has the function of automatically adjusting the temperature in the warehouse, and has functions such as temperature and humidity alarm, data recording, and mobile client monitoring.

　　(4) The Shenzhen and Zhengzhou warehouses of the explosion-proof cold storage project have been completed and are waiting for customer acceptance, and the Taiyuan warehouse is under construction.

　　Design features: environmentally friendly Freon refrigeration, water defrosting and defrosting method.
