根据E35-421标准，对九台回收设备和两台回收设备进行了测试。测量了以下数据:平均蒸汽和/或液体质量流量、设备对制冷剂的保留、回收效率、污染物转移、不同制冷剂的混合物以及再循环能力。给出了回收和再循环设备的使用结论。关键词:测试、性能、制冷剂、回收、设备、流体流量、流速、效率、混合物、污染。引用:研讨会，ASHRAE Trans。，1993年，第99卷，第2部分，论文编号DE-93-1-1429-439，图7，表2，参考文献。

Nine pieces of recovery equipment and two pieces of recycling equipment have been tested according to the E35-421 standard. The following data were measured - average vapour and/or liquid mass flow rates, retention of refrigerant by the equipment, recovery efficiency, transfer of contamination, mixture of different refrigerants, and recycling ability. Conclusions on the use of recovery and recycling equipment are given.KEYWORDS: testing, performance, refrigerants, recycling, equipment, fluid flow, flow rate, efficiency, mixtures, contamination.
