確認工(gong)業冷(leng)(leng)水(shui)(shui)機供電正常，無(wu)(wu)反相、缺(que)相現(xian)象(xiang);冷(leng)(leng)卻塔(ta)風機、冷(leng)(leng)卻水(shui)(shui)泵(beng)、冷(leng)(leng)凍水(shui)(shui)泵(beng)均為(wei)獨立(li)控制。開(kai)機前應確認電源正常，無(wu)(wu)反相、缺(que)相現(xian)象(xiang)。檢查工(gong)業冷(leng)(leng)水(shui)(shui)機主機、水(shui)(shui)泵(beng)、閥門、儀表及各種配件是(shi)(shi)否能正常打開(kai)，是(shi)(shi)否完(wan)好。檢查工(gong)業冷(leng)(leng)水(shui)(shui)機組油位是(shi)(shi)否正常

   開機前(qian)12小時接(jie)通冷(leng)水機組(zu)電(dian)源，使油(you)加熱器順利電(dian)加熱;啟動(dong)冷(leng)水機前(qian)，先對冷(leng)凍水循(xun)環系(xi)統和(he)冷(leng)卻水循(xun)環系(xi)統進行調(diao)試;檢查制冷(leng)系(xi)統壓(ya)力表讀數是(shi)否等于制冷(leng)劑在當地環境溫度下的飽和(he)壓(ya)力值(zhi);檢查壓(ya)縮機電(dian)機絕緣電(dian)阻(zu)，絕緣電(dian)阻(zu)應(ying)在3兆歐以上。

   對工業(ye)冷水(shui)(shui)機(ji)(ji)(ji)組的回(hui)水(shui)(shui)溫(wen)(wen)(wen)度(du)進行調節和設定后(hou)，機(ji)(ji)(ji)組就可以按照設定的溫(wen)(wen)(wen)度(du)自動運行。一旦回(hui)凍(dong)水(shui)(shui)溫(wen)(wen)(wen)度(du)達(da)到(dao)設定溫(wen)(wen)(wen)度(du)，在擰(ning)緊時主動停止制冷量調整，機(ji)(ji)(ji)組制冷量降低，直(zhi)至停止。冷水(shui)(shui)機(ji)(ji)(ji)制造商推薦的冷凍(dong)水(shui)(shui)溫(wen)(wen)(wen)度(du)范(fan)圍(wei)。分離蒸(zheng)發器的冷凍(dong)水(shui)(shui)溫(wen)(wen)(wen)度(du)允許為5℃，返回(hui)蒸(zheng)發器的冷凍(dong)水(shui)(shui)溫(wen)(wen)(wen)度(du)允許為25℃。建(jian)議(yi)冷凍(dong)水(shui)(shui)出口溫(wen)(wen)(wen)度(du)為7-12℃，溫(wen)(wen)(wen)升5℃
