Industrial refrigeration includes large-scale cold storages over 20,000 m3, like large-scale logistics distribution centers. However, this is just a part of it. Industrial refrigeration also includes food processing centers, chemical cooling, and ice worlds. The ice-making for the Beijing Winter Olympics Speed Skating Hall belongs to the category of industrial refrigeration, usually using ammonia or CO2 as the refrigerant or secondary fluid. Safety during system operation is particularly important, and It is a major concern to reduce management difficulty and human error in the industry. Automated control valves are the direction for the future.
