Jiangsu Daniang Dumplings 4000 tons large-scale food and catering cold storage ammonia to fluorine project

　　Project category: food cold storage, catering cold storage, ammonia to fluorine cold storage project

　　Project period: 54 days

　　Year of cooperation: 2015

　　Acceptance date: completed in March 2015

　　Project requirements: Jiangsu Daniang Dumplings Food Co., Ltd. designed ammonia refrigeration transformation in the cold storage system. The original refrigeration system had safety hazards. The scale of the transformed cold storage: 4000 tons of large cold storage, construction period: 54 days (including the Spring Festival from February 19th to 25th). The transformation of ammonia refrigerant to fluorine refrigerant alone solved the equipment replacement cost of more than 500,000 yuan for the customer, greatly reducing the cost of the customer’s cold storage transformation. The cold storage transformation project was successfully accepted and put into use in early March 2015.

　　Solution overview: The original complete set of refrigeration, freezing, quick freezing and other refrigeration equipment is old, with high failure rate and energy consumption. At the same time, the liquid ammonia refrigeration system has great safety hazards and urgently needs to be transformed and upgraded. Design temperature: 0~5℃ cold storage, -18~-23℃ freezer, -35~45℃ quick freezer.

　　Design features: The newly upgraded system is an environmentally friendly Freon refrigeration system
