IEC 62552-3:2015规定了通过内部自然对流或强制空气循环冷却的家用和类似制冷设备的基本特性，并建立了检查这些特性的试验方法。IEC 62552的本部分描述了确定能耗特性的方法，并定义了如何将这些方法组合起来，以估算不同使用和气候条件下的能耗。IEC 62552的本部分还定义了体积的测定。该标准的所有部分都经过了大量改写和更新，以应对新的测试要求、新的产品配置、电子产品控制和基于计算机的测试的出现- 房间数据收集和处理设备。为了更有效地进行分析，并更好地描述不同操作条件下的关键产品特性，第3部分（本部分）中许多能量测试的测试数据现在被分为多个部分（如稳态操作和除霜和回收）。能源消耗的测定方法已经完全修订，现在包括了许多内部检查，以确保符合标准要求的数据尽可能准确且高质量。交叉引用:EN 62552-2:2020BS EN 62552-1:2020IEC 62552-1:2015IEC 62552-2:2015EN 62552-1:2020购买本文件时可用的所有现行修订版均包含在购买本文件中。

IEC 62552-3:2015 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.Cross References:EN 62552-2:2020BS EN 62552-1:2020IEC 62552-1:2015IEC 62552-2:2015EN 62552-1:2020All current amendments available at time of purchase are included with the purchase of this document.
