        The Guanghua Chuangshi Dezhou Factory has a standard ice storage laboratory and a corrosion resistance laboratory, each batch of different types of ice-storage products have been through the ice-storage, ice-melting process of the actual operation and performance testing, flow resistance detection (pressure drop detection) , corrosion resistance testing.

Brief introduction to the core group：

    Zheng Qing: Graduated from Beijing University of Technology with a master's degree (thermal engineering) in 1996, and began to work on the promotion and practice of ice storage; Worked in many professional ice storage companies such as FAFCO, CIAT and Gaoling Energy. Now working in GHCS Company, he has detailed and in-depth practical experience in various types of ice storage equipment and ice storage systems, such as plastic coils and steel coils.He is one of the earliest professional practitioners of ice storage in China.

    The R&D center has ice storage laboratory and salt spray laboratory.  The main research fields are solid-liquid phase change heat transfer, gas-liquid two-phase flow heat transfer and flow, air conditioning load prediction, optimal control of ice storage air conditioning, corrosion resistance of metal materials, etc.

   (1)Ice storage laboratory

The ice storage laboratory can realize the research on the ice making, ice melting and resistance performance of internal melting coil, external melting coil and direct evaporative coil. Through the combination of theoretical simulation and experiment, more reasonable coil pipe diameter, optimal coil flow and arrangement spacing are selected according to the specific conditions of different projects, so that the ice making, ice melting and resistance performance of the ice storage coil can be comprehensively optimized.

Before the delivery of each project, the R&D Center conducts tests in the laboratory, invites customers to inspect various performance data in the laboratory, and also authorizes customers to remotely monitor the whole process. The R&D Center provides complete experimental reports. 

     (2)Corrosion resistance laboratory

The salt spray laboratory mainly studies the corrosion resistance of metal materials.  GHCS ice storage coil is made of SUS304 stainless steel (Zhangjiagang Posco, etc.). It is subject to strict passivation treatment to form a dense passivation film with excellent anti-corrosion performance before leaving factory.  It avoids various corrosion conditions caused by various free metals, welding heat affected areas, and surface effects of various processing links.  After sufficient passivation, no processing procedure is allowed.

   GHCS Factory has an independent pickling and passivation workshop. Each batch of ice coils is subject to pickling and passivation treatment before leaving the factory to improve the corrosion resistance of ice storage coils and extend their service life. The salt spray laboratory conducts spot check on each batch of pickling and passivation samples and issues inspection reports.
