恒溫(wen)控(kong)(kong)制系統是采用變(bian)頻(pin)(pin)調速(su)控(kong)(kong)制器實(shi)現冷卻塔進(jin)(jin)水(shui)口恒溫(wen)控(kong)(kong)制。當(dang)進(jin)(jin)水(shui)口水(shui)溫(wen)較高時(shi),變(bian)頻(pin)(pin)器控(kong)(kong)制風機高速(su)旋(xuan)轉(zhuan),快速(su)散熱。當(dang)進(jin)(jin)水(shui)口水(shui)溫(wen)較低(di)時(shi),變(bian)頻(pin)(pin)器控(kong)(kong)制風機低(di)速(su)旋(xuan)轉(zhuan)甚至(zhi)停(ting)機,從而達(da)到控(kong)(kong)制進(jin)(jin)水(shui)口恒溫(wen)目(mu)的。 因(yin)變(bian)頻(pin)(pin)器能使風機工作在最佳工況點(dian)上,因(yin)而節能效(xiao)果顯著。通常能達(da)20%-70%;其次(ci)風機轉(zhuan)速(su)下降,噪音也大(da)(da)大(da)(da)減少;另外變(bian)頻(pin)(pin)器的軟起,軟停(ting)功能也大(da)(da)大(da)(da)減少了(le)對機械的沖擊。
