Abstract
本发明提供了一种多联机系统控制方法、控制装置以及多联机系统。控制方法包括:多联机系统制冷运行,检测室外环境温度值T外环以及油分离器的回油毛细管的油温T油,同时在多联机系统中存在停机室外机时,获取停机室外机的第一低压饱和温度值Ts停机、停机室外机的第一高压饱和温度值Td停机以及处于正常运行状态室外机的第二低压饱和温度值Ts运行;根据油温T油、室外环境温度值T外环、第一低压饱和温度值Ts停机、第一高压饱和温度值Td停机以及第二低压饱和温度值Ts运行,判断停机室外机中的四通阀是否存在泄漏;若是,则控制多联机系统进入冷媒回收模式。本发明能够解决在室外机停止运行后,由于四通阀泄漏进而对压缩机造成损坏的技术问题。
