Beijing Minzu University Canteen Dual Temperature Cold Storage Project Plan

　　Project Category: Canteen Cold Storage, Dual Temperature Cold Storage

　　Project Period: 15 Days

　　Cooperation Year: 2020

　　Acceptance Date: March 2020

　　Project Requirements: The dual temperature cold storage project of the canteen of the Affiliated Middle School of Beijing Minzu University was undertaken and constructed by our company Haoshuang Refrigeration Chengdu Branch. It is mainly used for the refrigeration, freezing and preservation of various types of kitchen food in the school canteen. The canteen cold storage is located in Haidian District, Beijing. The cold storage is designed as a dual temperature cold storage with storage temperatures of 2~8℃ and -18℃ respectively.

　　Project Overview:

　　(1) The canteen dual temperature cold storage refrigeration system uses 2 sets of 3-horsepower American Emerson Copeland scroll compressor units, which have large cooling capacity, high cost performance, and are safe and reliable. In addition, the cold storage air cooler is equipped with Haoshuang customized DL high-efficiency strong wind air cooler, which has stable operation and low noise, and can supply air to a longer distance, so that the temperature in the warehouse can be cooled quickly and the convection circulation can be fast, thus achieving temperature uniformity in every corner.

　　(2) In terms of the storage panels, the dual-temperature cold storage project uses 120mm and 100mm polyurethane double-sided color steel insulation storage panels, which are energy-saving and environmentally friendly, with extremely high heat resistance, thus ensuring a stable low-temperature environment for the cold storage while greatly reducing the subsequent operating costs. The temperature control system uses an original imported thermostat to adjust the temperature in the warehouse. The controller has energy-saving functions and is equipped with temperature and humidity alarms, data recording, and mobile client monitoring functions.

　　(3) At present, the dual-temperature cold storage of the cafeteria has been installed and debugged, and has been accepted by Party A at one time. All equipment of the dual-temperature cold storage of the cafeteria has been operating normally since its use, and the person in charge is very satisfied with the operation of the cold storage.
