家用和类似用途电器 安全 第 2-104 部分：从空调和制冷设备中回收和/或再循环制冷剂的器具的特殊要求

[中文适用范围]： 本部分 IEC 60335 涉及用于从空调和制冷设备中回收和/或循环利用制冷剂的电气回收和/或循环利用设备的安全性。这适用于包含开放式驱动或电动机压缩机的空调、热泵和制冷设备，其最大额定电压单相设备不超过 300 V，其他所有设备不超过 600 V。不适用于普通家用但可能对公众造成危险的设备，如供商店、轻工业和农场服务人员使用的设备，也在本标准的范围内。上述设备可能由一个或多个工厂制造的组件组成。如果提供多个组件，则这些组件需一起使用，要求基于匹配组件的使用。注 101：在本文件中，术语“设备”表示回收设备。 [外文原描述]： IEC 60335-2-104:2021 deals with the safety of electrical recovery and/or recycle equipment to recover and/or recycle refrigerant from air conditioning and refrigeration equipment. This applies to air-conditioning, heat-pumps and refrigeration equipment incorporating open drive or motor-compressors, their maximum rated voltages being not more than 300 V for single phase appliances and 600 V for all other equipment. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by service personnel in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Clause 1 - The scope has been edited to reflect that "appliance" in this document means recovery and/or recycle equipment to recover and/or recycle refrigerant from air-conditioning and refrigeration equipment. b) Clause 2 - Normative references were added. c) Clause 3 - Some definitions were deleted, some were added. d) Subclause 7.1 - Some markings were deleted, some were added. e) Subclause 7.6 - Symbols were added for “read operator’s manual”, “operator’s manual; operating instructions” including coloring are placed in visible location; maximum allowable pressure markings following X MPa. f) Subclause 19.11.4 was modified. g) Subclause 21.1 was modified. h) Subclause 21.2 was modified. i) Subclause 22.102 was modified. j) Subclause 22.104.1.1 was modified. k) Subclause 22.104.5 was modified. l) Subclause 22.104.10 was modified. m) Subclause 22.104.11 was modified. n) Subclause 22.105.1 was modified. o) Subclause 22.107 was modified. p) Subclause 30.2 was moved to Clause 29. q) Annex AA was deleted and replaced with Annex AA. r) Annex BB was deleted and replaced with former IEC 60335-2-104 Annex CC (normative) Compatibility requirements following addition to Annex BB. s) Annex DD was deleted and replaced with Annex CC. t) New Annex DD was added. u) New Annex EE was added. This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its amendments.
