标准摘要
[中文适用范围]： IEC 62552-3:2015+AMD1:2020+AMD2:2025 CSV 规定了通过内部自然对流或强制空气循环冷却的家用及类似制冷设备的基本特性，并建立了用于验证这些特性的测试方法。IEC 62552 的本部分描述了测定能耗特性的方法，并定义了如何将这些特性组合起来，以估算在不同使用和气候条件下的能耗。IEC 62552 的本部分还定义了容积的测定方法。 标准的所有部分均经过大幅重写和更新，以应对新的测试要求、新的产品配置、电子产品控制系统的出现以及基于计算机的测试室数据采集与处理设备。 为了提高分析效率，并更准确地描述不同运行条件下产品的关键特性，第三部分（本部分）中的许多能耗测试数据现在被细分为不同组成部分（如稳态运行、除霜和恢复）。能耗测定的方法已完全修订，增加了许多内部校验步骤，以确保符合标准要求的数据尽可能精确、质量高。 第三部分（本部分）现在提供了一种方法，用于量化每个相关的能耗组成部分，并说明了如何将这些组成部分结合，以估算在不同条件下产品的能耗，期望各地在设定本地性能和能效标准时，可选择最适用的组成成分和权重，同时使用一套全球统一的测试测量数据。 在第三部分（本部分）的能耗测量中，任何隔室都不包括热质量（测试包），隔室温度基于空气温度传感器的平均值（与最热测试包的温度相比）。此外，未冻结隔室中温度传感器的位置也存在显著差异。 第三部分（本部分）的能耗测试现已规定了两种环境温度（16°C 和 32°C）。 第三部分（本部分）还增加了一项负载处理能效测试。 针对葡萄酒储存设备，增加了性能测试（第二部分）和能耗测试（第三部分，本部分）。 [外文原描述]： CORRECTED VERSION 2026-02 IEC 62552-3:2015+AMD1:2020+AMD2:2025 CSV specifies the essential characteristics of household and similar refrigerating appliances cooled by internal natural convection or forced air circulation, and establishes test methods for checking these characteristics. This part of IEC 62552 describes the methods for the determination of energy consumption characteristics and defines how these can be assembled to estimate energy consumption under different usage and climate conditions. This part of IEC 62552 also defines the determination of volume. - All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment. - For more efficient analysis and to better characterise the key product characteristics under different operating conditions, the test data from many of the energy tests in Part 3 (this part) is now split into components (such as steady state operation and defrost and recovery). The approach to determination of energy consumption has been completely revised, with many internal checks now included to ensure that data complying with the requirements of the standard is as accurate as possible and of high quality. - Part 3 (this part) now provides a method to quantify each of the relevant energy components and approaches on how these can be combined to estimate energy under different conditions on the expectation that different regions will select components and weightings that are most applicable when setting both their local performance and energy efficiency criteria while using a single set of global test measurements. - For energy consumption measurements in Part 3 (this part), no thermal mass (test packages) is included in any compartment and compartment temperatures are based on the average of air temperature sensors (compared to the temperature in the warmest test package). There are also significant differences in the position of temperature sensors in unfrozen compartments. - The energy consumption test in Part 3 (this part) now has two specified ambient temperatures (16°C and 32°C). - A load processing energy efficiency test has been added in Part 3 (this part). - Tests (both performance (Part 2) and energy (Part 3 (this part)) have been added for wine storage appliances. This corrected version of IEC 62552-3:2015+AMD1:2020+AMD2:2025 CSV incorporates the following correction: – Addition of normative reference IEC 62552-1:2015/AMD1:2020
