冷水機行業簡介

一、冷水機的作用是什么

冷(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)，又稱(cheng)冷(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)組(zu)、冷(leng)(leng)(leng)凍機(ji)(ji)、制(zhi)冷(leng)(leng)(leng)機(ji)(ji)組(zu)、冰(bing)水(shui)(shui)(shui)機(ji)(ji)組(zu)、冷(leng)(leng)(leng)卻(que)設(she)(she)備等，是(shi)一種(zhong)能提供(gong)恒溫、恒流(liu)、恒壓(ya)的冷(leng)(leng)(leng)卻(que)水(shui)(shui)(shui)設(she)(she)備，可以(yi)輸出比(bi)環(huan)境溫度(du)低的冰(bing)水(shui)(shui)(shui)，從而(er)起到直接(jie)冷(leng)(leng)(leng)卻(que)或間接(jie)換熱(re)的效果，它的作用(yong)主要是(shi)通(tong)過蒸汽(qi)壓(ya)縮或吸收式循(xun)環(huan)達(da)到制(zhi)冷(leng)(leng)(leng)效果，從而(er)對空氣或設(she)(she)備進(jin)行降(jiang)溫處理，在各(ge)行各(ge)業都有應用(yong)，比(bi)如電(dian)子(zi)(zi)工(gong)業會用(yong)冷(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)穩定電(dian)子(zi)(zi)元件內部在生(sheng)產(chan)線上的分子(zi)(zi)結構(gou)，提高(gao)電(dian)子(zi)(zi)元件的合格率；醫(yi)藥行業用(yong)冷(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)控制(zhi)發酵藥品(pin)的溫度(du)等。

二、冷水機組多少錢一臺

冷水機組是工業領域常用的水冷卻設備，用于冷卻各種設備，許多行業都會用到冷凍機，因此冷水機的種類眾多，價格也各異，根據冷凍機種類、制冷量、制冷形式、設備參數、核心部件質量等因素的不同，冷凍機的價格從幾百元到上萬元不等，工業冷水機一般都要幾萬元左右，具體價格要看制冷量、出水溫度等設備參數。在挑選冷水機組的時候，要注意根據需求選擇合適的型號，通過有實力、有資質的冷水機品牌廠家進行購買。

三、冷水機組制冷原理

冷(leng)(leng)(leng)(leng)(leng)水(shui)機組用(yong)于給設(she)備制(zhi)冷(leng)(leng)(leng)(leng)(leng)，一(yi)般由壓(ya)(ya)縮機、蒸(zheng)(zheng)(zheng)發器(qi)(qi)(qi)、冷(leng)(leng)(leng)(leng)(leng)凝(ning)器(qi)(qi)(qi)、膨脹閥四(si)大核心(xin)部(bu)(bu)件組成(cheng)(cheng)，四(si)個部(bu)(bu)分通過管道進(jin)(jin)行(xing)連(lian)接，它的(de)(de)工作(zuo)(zuo)原理是：冷(leng)(leng)(leng)(leng)(leng)水(shui)機利用(yong)制(zhi)冷(leng)(leng)(leng)(leng)(leng)劑作(zuo)(zuo)為制(zhi)冷(leng)(leng)(leng)(leng)(leng)工質，制(zhi)冷(leng)(leng)(leng)(leng)(leng)劑會在蒸(zheng)(zheng)(zheng)發器(qi)(qi)(qi)內吸收被冷(leng)(leng)(leng)(leng)(leng)卻物的(de)(de)熱(re)(re)量并(bing)汽(qi)化成(cheng)(cheng)蒸(zheng)(zheng)(zheng)汽(qi)，壓(ya)(ya)縮機不斷地(di)將(jiang)產生的(de)(de)蒸(zheng)(zheng)(zheng)汽(qi)從蒸(zheng)(zheng)(zheng)發器(qi)(qi)(qi)中(zhong)抽出，并(bing)進(jin)(jin)行(xing)壓(ya)(ya)縮，經壓(ya)(ya)縮后的(de)(de)高溫、高壓(ya)(ya)蒸(zheng)(zheng)(zheng)汽(qi)被送(song)到冷(leng)(leng)(leng)(leng)(leng)凝(ning)器(qi)(qi)(qi)后向冷(leng)(leng)(leng)(leng)(leng)卻介質（如(ru)水(shui)、空氣等(deng)）放熱(re)(re)冷(leng)(leng)(leng)(leng)(leng)凝(ning)成(cheng)(cheng)高壓(ya)(ya)液體，再經節流(liu)機構降壓(ya)(ya)后進(jin)(jin)入蒸(zheng)(zheng)(zheng)發器(qi)(qi)(qi)，再次汽(qi)化，吸收被冷(leng)(leng)(leng)(leng)(leng)卻物體的(de)(de)熱(re)(re)量，如(ru)此(ci)周而復(fu)始(shi)地(di)循環，實現(xian)制(zhi)冷(leng)(leng)(leng)(leng)(leng)效果。
