  • A case study of Fudan University cold storage project

    Project Overview: Fudan University Scientific Research cold storage project is designed and built by Haoshuang refrigeration. The cold storage project is divided into three phases, all completed in 2013, and has been put into use now. There are laboratory cold storage, low temperature cold storage and plasma cold storage. Up to now, there are no imported brands of air coolers imported from Italy, such as comtel, which are imported from Germany. Fudan University was founded in 1905, formerly known as Fudan public school. It is the first university independently founded by Chinese people. Its founder is Ma Xiangbo, a famous educator in modern China. In 1917, Fudan public school was renamed private Fudan University

  • Case study on low temperature cold storage in Tongji Environmental Research Institute of Jiaxing

    Project introduction: the cold storage of Tongji Environmental Research Institute of Jiaxing is used as the Yangtze River environmental sample bank, biological soil, fish, aquatic products, etc. the refrigerated samples need to be stored for 30 years. Meanwhile, the temperature of the cold storage is - 25 ℃, and the upper and lower temperature can not exceed ± 2 ℃. After the design and research of Haoshuang refrigeration, the cold storage adopts double stainless steel plate (service life is 40 years), which can ensure the sample storage requirements for a longer time. At the same time, when the fan defrosts, the cooling engineer uses two machines to work at the same time, one for defrosting and the other for forced refrigeration, so as to ensure that the heat generated by defrosting can reduce the temperature in the cold storage to the minimum, and also meet the requirement that the fluctuation of the temperature in the cold storage should not exceed ± 2 ℃. In addition, the engineer used PLC automatic control elements for the cold storage to realize the automatic control of the cold storage. Customer introduction
