Scope
GB/T 31510-2015 is the English-translated version of 远置式压缩冷凝机组冷藏陈列柜系统经济运行.
GB/T 31510-2015 specifies the basic requirements for the economic operation of refrigerated display cabinet systems with remote refrigerant compressor condensing units, together with the methods of evaluation and the energy management measures.
Clause 1 states that the standard applies to display cabinet systems used for the sale and exhibition of food, and that it does not apply to non-retail vending machines or to refrigeration showcase systems.
Clause 2, Normative references, cites GB/T 21001.1, GB/T 21001.2-2007 and GB 26920.1, and clause 3, Terms and definitions, draws its terms from those same three documents.
Clause 3 defines the far-mounted condensing unit refrigerated showcase system itself and then four energy quantities: the direct electrical energy consumption of display cabinets (DEC), the refrigeration electrical energy consumption of display cabinet systems (RECs), which for a water-cooled refrigeration system includes the energy used by the cooling tower fan and the pump, the total energy consumption of display cabinet systems (TECs), which is DEC and RECs combined, and the energy consumption coefficient of display cabinet systems (ECCs), the ratio of TECs to the total display area.
The draft published on the source page breaks off at the end of clause 3, so it does not show the clauses that carry the evaluation methods and the energy management measures announced in clause 1.
The page records the standard as placed under the National Standardization Technical Committee for Energy and Management (SAC/TC20). It was issued on 15 May 2015 and has applied since 1 December 2015.
