恒溫(wen)控(kong)制(zhi)(zhi)系統是采用變(bian)(bian)(bian)頻(pin)調速(su)控(kong)制(zhi)(zhi)器(qi)實現冷(leng)卻塔(ta)進(jin)水口(kou)恒溫(wen)控(kong)制(zhi)(zhi)。當進(jin)水口(kou)水溫(wen)較高時,變(bian)(bian)(bian)頻(pin)器(qi)控(kong)制(zhi)(zhi)風機(ji)高速(su)旋轉,快速(su)散熱(re)。當進(jin)水口(kou)水溫(wen)較低時,變(bian)(bian)(bian)頻(pin)器(qi)控(kong)制(zhi)(zhi)風機(ji)低速(su)旋轉甚至(zhi)停機(ji),從而(er)達(da)到(dao)控(kong)制(zhi)(zhi)進(jin)水口(kou)恒溫(wen)目(mu)的。 因變(bian)(bian)(bian)頻(pin)器(qi)能使風機(ji)工(gong)作在(zai)最佳工(gong)況點上,因而(er)節能效(xiao)果顯著。通常能達(da)20%-70%;其(qi)次風機(ji)轉速(su)下降,噪音也大(da)大(da)減少(shao);另外(wai)變(bian)(bian)(bian)頻(pin)器(qi)的軟起,軟停功能也大(da)大(da)減少(shao)了對機(ji)械(xie)的沖擊(ji)。
