1 Scope

GB 44015-2024 is the Chinese national standard on minmum allowable of energy efficiency and energy efficiency grades for cold store(box) and refrigerant compressor condensing unit, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 February 2025. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the energy efficiency levels, technical requirements, test methods and implementation of standards for cold storage (boxes) and compression condensing units: This document is applicable to prefabricated cold storage (boxes), civil cold storage and volumetric refrigeration compression condensing units driven by motors: This document does not apply to the following products or refrigeration systems:

a) Refrigeration systems other than motor-compressor driven;

b) refrigerated containers, refrigerated containers and transport refrigerators and freezers with or without refrigeration systems;

c) On-site assembled refrigeration compression condensing units;

d) Evaporative condensing refrigeration compression condensing unit:
