本实施例的空调系统采用气悬浮式离心压缩机，制冷循环中无需润滑油，从而能提高换热器的换热效率，并根据实际使用的阀类件是否需要润滑油可取消回油系统及模块组合时的均油管，简化安装施工操作，简化制冷系统和控制程序，维护方便。
克服了相关技术的变频多联式空调器带油运行使换热器的换热效率下降、制冷系统和控制程序复杂的缺陷，采用无油气悬浮离心式压缩机，制冷循环中没有润滑油，从而能提高换热器的换热效率，简化安装施工操作，简化制冷系统和控制程序，维护方便，降低成本。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开实施例可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
