當然，溢流(liu)閥(fa)也有可能被堵塞。也會(hui)(hui)有高(gao)壓報(bao)(bao)警，但是這種常見的故障是服務器(qi)(qi)一旦(dan)啟動，服務器(qi)(qi)一運行就(jiu)會(hui)(hui)報(bao)(bao)警。與(yu)前面幾類不同，這里也提到，如果發出底壓報(bao)(bao)警，一般是制冷劑泄(xie)漏造(zao)成(cheng)的。也有可能是溫(wen)降(jiang)(jiang)過(guo)低，導(dao)致(zhi)空調蒸發器(qi)(qi)工作壓力降(jiang)(jiang)低超過(guo)原廠**工作壓力設置，也導(dao)致(zhi)底壓報(bao)(bao)警！
