電子室環(huán)境對主控制器的影響
電子室內(nèi)的溫、濕度對主控制器有一定影響,強(qiáng)制散熱的主控制器影響更大。溫、濕度過高不一定使主控制器立即發(fā)生故障,但長期處于這種環(huán)境下必定會(huì)使主控制器故障率增高,而且從我們的統(tǒng)計(jì)來看,濕度的影響比溫度的影響更大。根據(jù)2005年以來的統(tǒng)計(jì),每年3-6月份的主控制器故障次數(shù)約占到全年總數(shù)的1/3到一半多,這段時(shí)期正值南方濕熱的雨季,中央空調(diào)往往會(huì)補(bǔ)充大量的新風(fēng),電子室內(nèi)濕度會(huì)有所增大。這種情況下發(fā)生的主控制器異常,一般均通過復(fù)位或重新啟動(dòng)后可以恢復(fù),只有個(gè)別需要更換新的主控制器。
