DB31/ 643-2012 in English

This standard specifies the energy efficiency limit values and energy efficiency grades for freezing equipment including fluidized, spiral, and plate types. It provides a framework for evaluating the energy performance of such devices, ensuring a consistent basis for comparison across different models and manufacturers. The standard outlines specific criteria that define the minimum acceptable energy efficiency levels, which are used to classify the equipment into different grades. These grades help in identifying more energy-efficient options available in the market. The requirements are designed to promote energy conservation and support sustainable practices within the industry. The standard also includes test methods and procedures to assess the energy efficiency of the equipment accurately. It serves as a reference for manufacturers, regulatory bodies, and consumers to ensure compliance with energy efficiency standards.
