Zusammenfassung:Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor. 提供了用于将润滑剂从第一压缩机清洗至第二压缩机的系统和方法。控制模块接收润滑剂清洗命令，在第一压缩机保持处于ON模式时将第二压缩机关闭至OFF模式，限制来自第二压缩机的出口的工作流体流入第一压缩机，并允许从第一压缩机的出口排出的压缩的工作流体流入第二压缩机的入口，使得第二压缩机中的润滑剂流入第一压缩机。
