标准摘要
[中文适用范围]： 本ISO 5149第2部分适用于制冷装置的设计、建造和安装，包括管道、部件、材料以及与该装置直接相关的辅助设备，这些内容未在ISO 5149-1、ISO 5149-3或ISO 5149-4中涵盖。它还规定了测试、调试、标记和文件的要求。次要传热回路的要求被排除，除了与制冷装置相关的安全设备外。本部分适用于新的制冷装置、现有装置的扩展或修改，以及转移到另一个地点并操作的用过的装置。本部分适用于：a) stationary或mobile的制冷装置，包括热泵；b) 次要冷却或加热系统；c) 制冷装置的位置；d) 在本部分实施后更换的部件和添加的组件，如果它们在功能和容量上不相同。本部分不适用于“机动车空调”。它不适用于储存商品的腐烂或污染，但也适用于将装置转换为另一种制冷剂的情况。 [外文原描述]： ISO 5149-2:2014 is applicable to the design, construction, and installation of refrigerating systems, including piping, components, materials, and ancillary equipment directly associated with such systems, which are not covered in ISO 5149‑1, ISO 5149‑3, or ISO 5149‑4. It also specifies requirements for testing, commissioning, marking, and documentation. Requirements for secondary heat-transfer circuits are excluded except for any safety devices associated with the refrigerating system. ISO 5149-2:2014 is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for used systems, being transferred to and operated on another site. ISO 5149-2:2014 applies to: a) refrigerating systems, stationary or mobile, of all sizes including heat pumps; b) secondary cooling or heating systems; c) the location of the refrigerating systems; and d)replaced parts and added components after the adoption of this part of ISO 5149, if they are not identical in function and in capacity. ISO 5149-2:2014 does not cover "motor vehicle air conditioners". It does not apply to goods in storage, with respect to spoilage or contamination, but it also applies in the case of the conversion of a system for another refrigerant.
