Design of refrigeration system for a large-scale aquatic product processing project in Zhoushan

This project involves a comprehensive aquatic product logistics and processing base in Zhoushan, including raw material storage, low-temperature processing, quick freezing, and finished product storage. To address challenges such as high total cooling demand, multiple temperature zones in the refrigeration system, complex operating conditions, large daily cooling load variations in processing workshops, and uneven temperature distribution in cold storage rooms, green and energy-saving solutions are proposed for the refrigeration system. CFD numerical simulation analysis method is used to study airflow patterns and temperature distribution in large-scale automatic three-dimensional cold storage room. The results show that for a tall three-dimensional cold storage room, applying warehouse-type air cooler downward air supply with symmetrical arrangement at both short ends of the cold storage room achieves uniform air distribution and better air distribution, maintaining temperature fluctuations within 1.5 ℃.
