恒溫(wen)控(kong)(kong)制(zhi)(zhi)系統(tong)是采用變(bian)頻調速(su)控(kong)(kong)制(zhi)(zhi)器實現(xian)冷卻塔進水口恒溫(wen)控(kong)(kong)制(zhi)(zhi)。當進水口水溫(wen)較(jiao)高時(shi),變(bian)頻器控(kong)(kong)制(zhi)(zhi)風機(ji)高速(su)旋轉,快(kuai)速(su)散熱。當進水口水溫(wen)較(jiao)低時(shi),變(bian)頻器控(kong)(kong)制(zhi)(zhi)風機(ji)低速(su)旋轉甚至停機(ji),從而(er)達到控(kong)(kong)制(zhi)(zhi)進水口恒溫(wen)目的(de)(de)。 因變(bian)頻器能使風機(ji)工(gong)作在最佳(jia)工(gong)況(kuang)點上,因而(er)節能效(xiao)果(guo)顯(xian)著。通常能達20%-70%;其次風機(ji)轉速(su)下降,噪音也(ye)大(da)大(da)減(jian)少(shao);另外變(bian)頻器的(de)(de)軟起,軟停功能也(ye)大(da)大(da)減(jian)少(shao)了(le)對機(ji)械的(de)(de)沖擊。
