Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to various commercial refrigerating appliances, including commercial refrigerated cabinets, refrigerated beverage vending machines, commercial ice machines, soft-serve ice cream makers, and mechanically refrigerated transport equipment such as refrigerated containers and mobile cold storage. It does not apply to non-vapor compression refrigeration equipment, medical or laboratory refrigerators, or wine storage cabinets. Manufacturers of these commercial cooling products must comply with this mandatory standard to access the Chinese market. The standard references several other standards like GB/T 5338.2-2023 and GB 29753-2023 for specific product classifications.

Exigences techniques

The standard specifies the minimum allowable values of energy efficiency and energy efficiency grades for a wide range of commercial refrigeration equipment. It establishes the maximum energy consumption limits (TECmax) for different categories of commercial refrigerated cabinets, taking into account factors such as cabinet type, climate class, and defrost system. Products must not exceed these calculated energy consumption limits to be deemed compliant. For refrigerated beverage vending machines and commercial ice machines, the standard defines specific energy consumption limits based on daily energy use or unit output. The calculation methods involve various adjustment coefficients for low power modes and ice hardness factors, referencing standards like SB/T 10940-2012. Additionally, the standard sets energy efficiency grades, typically ranging from Grade 1 (most efficient) to Grade 5 (or Grade 3 for ice machines and soft-serve makers). Manufacturers must ensure their products meet at least the declared energy efficiency grade and adhere to strict tolerance limits. The standard also introduces requirements for refrigerated containers and mechanically refrigerated vehicle containers, calculating limits based on internal volume and insulation foam agents.

Méthodes d’essai

The testing procedures involve measuring the total energy consumption (TEC) over a 24-hour period under specified ambient temperature and humidity conditions. For commercial refrigerated cabinets, tests are conducted using specific test packages (M-packages) as defined in the standard's annexes. Accurate measurement of effective volume and total display area (TDA) is crucial for determining compliance. For vending machines, the test includes a vending capability test followed by a 24-hour energy consumption test, evaluating both standard and low power modes. The standard also details specific testing methods for ice machines and transport refrigeration, referencing standards like GB/T 28493-2012 and GB/T 5338.2-2023.

Questions fréquentes

What products are regulated under GB 26920-2024?

GB 26920-2024 regulates commercial refrigerating appliances, including commercial refrigerated cabinets, refrigerated beverage vending machines, commercial ice machines, soft-serve ice cream makers, refrigerated containers, and mechanically refrigerated mobile cold storage.

Are there any updates from the previous version of GB 26920?

Yes, GB 26920-2024 is a consolidation of previous parts (GB 26920.1-2011, GB 26920.2-2015, GB 26920.3-2019). It expands the scope to include commercial ice machines, soft-serve ice cream makers, and transport refrigeration equipment, and updates the energy efficiency limits and grading criteria.

How is the energy efficiency grade determined for commercial refrigerated cabinets?

The energy efficiency grade is determined by calculating the energy efficiency index (η), which is the ratio of the measured energy consumption to the maximum allowable energy consumption limit. Grades range from 1 (most efficient) to 5.
