家用及轻型商用离网和不可靠电网制冷器具 - 特性和测试方法 - 性能要求和能耗

[中文适用范围]： IEC 63437:2025 规定了适用于家庭及类似用途或轻商业用途的离网或电网不可靠的制冷设备的基本特性，这些设备采用内部自然对流或强制空气对流方式进行冷却。本标准定义了针对电网不可靠或离网条件设计的制冷设备的输入电压供应信号。电网不可靠的条件可能是由于电力供应中的干扰，如停电，或是电力质量的问题，如电压尖峰和浪涌，这些问题可能会对制冷设备的性能造成挑战。在此上下文中，离网供电可以是太阳能板或独立的太阳能家庭系统生成的，这些系统未连接到电力网。本文件模拟了离网和电网不可靠条件下的电力特性，但并未规定用于评估发电机、太阳能板、太阳能家庭系统或其他产生供电信号的系统的性能要求或测试程序。本文件中定义的供电信号也可用于评估其他制冷设备的性能，例如医疗或实验室设备、专业存储冰箱或冷冻柜、冷藏展示柜、饮料冷却器或冰淇淋冷冻柜等。本文件规定了测量功能性能特性及要求的测试方法。本标准不适用于设计用于高质量和稳定电网的制冷设备，也不适用于使用燃料驱动的吸收式冷却技术的制冷设备。本标准适用于任何用于家庭或轻商业用途的制冷设备，这些设备在离网或电网不可靠运行条件下具备适当的性能，能够抵抗电力中断和供电变化。离网和电网不可靠的制冷设备是那些设计用于独立、间歇或畸变的市电供应的设备。市电供应在电网不可靠条件下假设为交流电（AC），在离网条件下假设为直流电（DC）。本文件也适用于混合制冷设备。 [外文原描述]： IEC 63437:2025 specifies the essential characteristics of off grid and unreliable grid refrigerating appliances for domestic and similar use or light commercial use, cooled by internal natural or forced air convection. It defines input voltage supply signals for appliances designed for unreliable grid and off grid conditions. An unreliable grid condition can be the result of disturbances on the electricity supply, such as power outages, or issues with power quality, such as voltage spikes and surges, that could cause performance challenges to refrigerating appliances. An off grid supply, in this context, for example is generated by a solar panel or a stand-alone solar home system that is not connected to the power grid. This document simulates the power characteristics in off grid and unreliable grid conditions but does not specify requirements or test procedures to assess performance of generators, solar panels, solar home system or any other system generating a supply signal. The supply signals defined in this document can also be used for evaluation of the performance of other refrigerating appliances such as medical or laboratory appliances, professional storage refrigerators or freezers, refrigerated display cabinets, beverage coolers or ice cream freezers. This document specifies the test methods for measuring the functional performance characteristics and requirements. This document does not apply to refrigerating appliances designed for a good quality and stable electricity grid and refrigerating appliances utilising fuelled absorption cooling technology. This document is applicable to any refrigerating appliance for domestic or light commercial use that has a rated performance to properly operate off grid or under unreliable grid operating conditions resisting power interruptions and supply variations. Off grid and unreliable grid refrigerating appliances are appliances intended to for use with standalone or intermittent or distorted electrical mains. Electrical mains supply is assumed to be alternating current (AC) for unreliable grid or direct current (DC) for off grid. This document is also applicable to hybrid refrigerating appliances.
