Cold Storage Industry Development Classification and Refrigeration System Design Guide
From 1955 Ice Cellars to PLC Intelligent Control: A Design Guide Across Cold Room Classes
China's modern cold storage industry, starting in 1955, has achieved standardized full-link cold chain coverage, and since 2020 national support policies have driven automated management and energy reduction. Cold rooms are classified by temperature, structure, refrigerant and capacity, from small civilian to large industrial facilities, with small systems operating a closed compression, condensation, throttling and evaporation cycle, preferring single-unit configuration and dual-stage compression for high pressure ratios. Refrigerant selection prioritizes low ODP and GWP values, with carbon dioxide emerging as the most promising natural option. EXTRCOOL provides variable-frequency cold storage solutions.
