Zhangjiagang Flavor Explosion-proof Cold Storage Low-temperature Refrigeration Room Project Construction Plan

　　Project Category: Flavor and Spice Condiment Cold Storage Project, Low-temperature Refrigeration Room

　　Project Period: 30 Days

　　Year of Cooperation: 2018

　　Acceptance Date: June 2018

　　Project Requirements: 2～10℃ Baicheng 500㎡ Flavor Explosion-proof Low-temperature Refrigeration Room New Project, constructed by our company HAOCOOL Refrigeration, mainly used for storing flavors, spices and condiments, etc. The cold storage is 500 square meters in total, all explosion-proof equipment is used. The project was completed in June 2018, ensuring that the cold storage acceptance meets the conventional cold storage acceptance and also passes the national explosion-proof storage inspection and acceptance. All equipment and accessories in the flavor explosion-proof low-temperature refrigeration room reach the EXdIIBT4 explosion-proof level. The cold storage case of this project has been completed and delivered to customers for use, and has been well received by customers.

　　Project Overview:

　　(1) The cold storage of this project uses Emerson Copeland scroll compressor units to drive two air coolers, one for use and one for standby. The cool storage is equipped with 4 Daikin air conditioning units. The cold storage board uses FM-certified B1-level flame-retardant double-sided color steel plates and 100mm thick double-sided 0.6 Baosteel color steel cold storage boards.

　　(2) The fragrance explosion-proof low-temperature cold storage room uses R404 refrigerant and the lubricant uses Emerson compressor special oil.

　　(3) The fragrance explosion-proof low-temperature cold storage room control system uses Siemens PLC, which adopts centralized control and has remote monitoring function, independent control and display of technical data. PLC control system detects the temperature in the storage and has temperature over-temperature alarm function.

　　(4) Emerson Copeland scroll compressors use one for use and one for standby, over-temperature simultaneous start, automatic switching to the standby unit when the unit fails, and rotation switching adjustable for 1-72 hours.

　　(5) The explosion-proof cold storage project unit uses Emerson refrigeration compressors, which have low vibration, low noise, good operating reliability, good fan appearance, and low operating noise.

　　Design features: environmentally friendly Freon refrigeration, direct expansion liquid supply
