工作原理

制(zhi)冷是(shi)采(cai)用一定(ding)(ding)的(de)方法(fa)，在(zai)(zai)一定(ding)(ding)的(de)時間(jian)(jian)和(he)空(kong)(kong)(kong)間(jian)(jian)內，使某(mou)一物(wu)體(ti)或(huo)空(kong)(kong)(kong)間(jian)(jian)達(da)(da)到比周(zhou)圍環(huan)境介質(zhi)更低的(de)溫度，并維(wei)持(chi)在(zai)(zai)給定(ding)(ding)的(de)溫度范(fan)圍內。為了(le)使某(mou)一物(wu)體(ti)或(huo)空(kong)(kong)(kong)間(jian)(jian)達(da)(da)到或(huo)維(wei)持(chi)一定(ding)(ding)的(de)低溫，就必須采(cai)用一定(ding)(ding)的(de)技術手段和(he)方法(fa)，連續不斷地取(qu)出物(wu)體(ti)或(huo)空(kong)(kong)(kong)間(jian)(jian)內的(de)熱量，所采(cai)用的(de)技術術稱為制(zhi)冷技術。

制冷方法

復疊式低溫(wen)(wen)冷(leng)(leng)(leng)水機由(you)兩個(ge)(ge)或(huo)兩個(ge)(ge)以上獨立(li)的制冷(leng)(leng)(leng)系(xi)統組成，每一系(xi)統均(jun)可采用單級或(huo)雙級壓縮制冷(leng)(leng)(leng)系(xi)統。這(zhe)兩個(ge)(ge)部分(fen)通過(guo)一個(ge)(ge)冷(leng)(leng)(leng)凝蒸發器聯系(xi)起來(lai)，它既是低溫(wen)(wen)循(xun)環(huan)(huan)的冷(leng)(leng)(leng)凝器，也是高(gao)溫(wen)(wen)循(xun)環(huan)(huan)的蒸發器，即高(gao)溫(wen)(wen)循(xun)環(huan)(huan)中制冷(leng)(leng)(leng)劑的蒸發用來(lai)冷(leng)(leng)(leng)凝低溫(wen)(wen)循(xun)環(huan)(huan)中的制冷(leng)(leng)(leng)劑。這(zhe)樣，低溫(wen)(wen)循(xun)環(huan)(huan)吸收的熱量(liang)（制冷(leng)(leng)(leng)劑）傳(chuan)給高(gao)溫(wen)(wen)循(xun)環(huan)(huan)的制冷(leng)(leng)(leng)劑，冷(leng)(leng)(leng)水機維修價格，高(gao)溫(wen)(wen)循(xun)環(huan)(huan)的制冷(leng)(leng)(leng)劑再將熱量(liang)傳(chuan)給環(huan)(huan)境介質（空氣或(huo)水）。

復疊式低溫冷水機制冷循(xun)環既能(neng)滿足(zu)在(zai)較低的蒸(zheng)發(fa)(fa)溫度下(xia)有合適的蒸(zheng)發(fa)(fa)壓(ya)力，又(you)能(neng)滿足(zu)在(zai)環境(jing)溫度下(xia)適中(zhong)的冷凝(ning)壓(ya)力。

在抽取制(zhi)冷劑的(de)過程中應(ying)(ying)注意機器設備溫度和壓(ya)力的(de)變化如不(bu)正常應(ying)(ying)查明(ming)原因(yin)，待(dai)排(pai)除后(hou)再抽取。冷水機系統排(pai)放(fang)余氨(an)時，閥門開得不(bu)要(yao)(yao)過大，咸(xian)寧冷水機，要(yao)(yao)有較充分的(de)水以其是在城市更應(ying)(ying)注意。另外(wai)，應(ying)(ying)將所有的(de)閥門開啟與(yu)排(pai)放(fang)管(guan)相通，冷水機維修保養，否則(ze)氨(an)放(fang)不(bu)干凈(jing)，設備檢修時人員(yuan)將受到傷(shang)害用(yong)鋼瓶裝(zhuang)制(zhi)冷劑時，一定要(yao)(yao)密(mi)切注意砰稱的(de)讀數，防(fang)止(zhi)鋼瓶裝(zhuang)得過多(duo)而出(chu)現意外(wai)事故用(yong)氨(an)罐裝(zhuang)氨(an)時也(ye)同(tong)樣要(yao)(yao)防(fang)止(zhi)裝(zhuang)載 超量。
