恒溫(wen)(wen)控制(zhi)系統是采用變(bian)頻(pin)調速(su)(su)(su)控制(zhi)器實(shi)現冷卻塔進(jin)(jin)(jin)水(shui)(shui)口恒溫(wen)(wen)控制(zhi)。當進(jin)(jin)(jin)水(shui)(shui)口水(shui)(shui)溫(wen)(wen)較高時,變(bian)頻(pin)器控制(zhi)風機(ji)(ji)高速(su)(su)(su)旋(xuan)轉(zhuan),快(kuai)速(su)(su)(su)散熱。當進(jin)(jin)(jin)水(shui)(shui)口水(shui)(shui)溫(wen)(wen)較低時,變(bian)頻(pin)器控制(zhi)風機(ji)(ji)低速(su)(su)(su)旋(xuan)轉(zhuan)甚(shen)至停(ting)(ting)機(ji)(ji),從而(er)達到控制(zhi)進(jin)(jin)(jin)水(shui)(shui)口恒溫(wen)(wen)目的。 因(yin)變(bian)頻(pin)器能(neng)(neng)(neng)使風機(ji)(ji)工(gong)作在最佳工(gong)況點(dian)上,因(yin)而(er)節能(neng)(neng)(neng)效果(guo)顯著。通(tong)常能(neng)(neng)(neng)達20%-70%;其次風機(ji)(ji)轉(zhuan)速(su)(su)(su)下降,噪音(yin)也(ye)大(da)大(da)減(jian)少;另外變(bian)頻(pin)器的軟起,軟停(ting)(ting)功(gong)能(neng)(neng)(neng)也(ye)大(da)大(da)減(jian)少了對機(ji)(ji)械的沖(chong)擊。
