Changshu Nanomicrobiology Class A Explosion-proof Cold Storage Project Construction Plan

　　Project Category: Low-temperature Explosion-proof Cold Storage Project

　　Project Period: 70 Days

　　Year of Cooperation: 2020

　　Acceptance Date: October 2020

　　Project Requirements: Changshu Nanomicrobiology Technology 1300m³ Class A Explosion-proof Cold Storage New Project, constructed by our company HAOCOOL Refrigeration. According to the customer’s production and use requirements, our company HAOCOOL Refrigeration designed a 1300m³ explosion-proof cold storage for it, including 1 Class A warehouse warm room, 3 cold storages with a temperature of 2-8℃, 2 ultra-low temperature cold storages at -20℃, 1 buffer floor and 1 freezer with a temperature of -15～-20℃, a total of 8 rooms.

　　Project Overview:

　　(1) Warehouse insulation 100mm phenolic insulation board (machine board), A2 grade flame retardant, double-sided 0.5 stainless steel, freezer 200mm phenolic insulation board (machine board) A2 grade flame retardant, double-sided 0.5 stainless steel

　　(2) Cold storage installation outdoor refrigeration unit brand: Emerson Copeland compressor, No. 2 and No. 4 cold storages are equipped with two refrigeration units, and each of the remaining cold storages is equipped with a unit. The unit condensation method is air cooling, and the unit form is a single-machine air-cooled box type. The terminal uses a special customized evaporator without a motor, and the wide plate spacing prevents frost. When the refrigeration equipment cools the temperature of the terminal evaporator coil, the air volume of the fresh air system in the warehouse is used to bring out the cold of the evaporator coil, thereby achieving the purpose of cooling the cold storage. When the temperature reaches the shutdown temperature, the fresh air unit is turned off, and when it reaches the startup temperature, the fresh air unit is started.

　　(3) Brand of evaporator in the warehouse: special evaporator (equipped with double-layer water accumulation tray to prevent condensation and dripping), stainless steel shell + epoxy anti-corrosion wide-pitch fins, cold evaporator adopts stainless steel shell + explosion-proof motor + sodium ring corrosion fins.

　　(4) Electric control system: 22 sets of explosion-proof lamps and 3 sets of explosion-proof electric boxes for cold storage, PLC intelligent control touch screen (to meet the requirement of temperature data U disk storage function in each area) + mechanical temperature control, remote alarm viewing, clear grasp of the power consumption of various aspects of the cold storage, and provide users with analysis of the energy consumption of the cold storage.

　　Design features: environmentally friendly Freon refrigeration, IICT4 explosion-proof grade standard
