制冷系统含油率的测量方法概述

摘要

制冷系统中必须将含油率控制在一定范围内,以保证性能和可靠性.对制冷系统的含油率测试显得尤为重要,以便评估压缩机或系统设计的优劣.根据不同的测试位置可以采用不同的测试原理,而精度、技术难度、成本等方面决定了每一种方法的应用场合.%The oil circulation rate (OCR) in refrigeration system must be controlled at a certain range in order to en-sure the performance and reliability. The OCR measurement is so important that it can evaluate a compressor or refrig-eration system whether it is superior or inferior. According to different measurement places, different principle can be applied. Application of each method depends on accuracy, technique difficulties and cost, et al.
