1、風冷式(shi)冷水(shui)機組是(shi)中央空(kong)調的一種(zhong)類型(xing)，而(er)全氟一拖多小型(xing)空(kong)調系統(tong)是(shi)分體空(kong)調一種(zhong)形式(shi)的演變。
2、風(feng)(feng)(feng)冷(leng)式冷(leng)水機組的(de)冷(leng)水出水溫(wen)度(du)在(zai)7～12℃之間(jian)，通過(guo)風(feng)(feng)(feng)機盤(pan)管或(huo)組合式空(kong)(kong)調(diao)器(qi)等末端系(xi)統處(chu)理后，進入室(shi)內(nei)(nei)冷(leng)風(feng)(feng)(feng)的(de)溫(wen)度(du)為15～18℃之間(jian)，使(shi)人充分感(gan)覺到中(zhong)央(yang)空(kong)(kong)調(diao)的(de)舒適(shi)；而全氟一拖多(duo)小(xiao)型空(kong)(kong)調(diao)系(xi)統的(de)蒸發(fa)溫(wen)度(du)在(zai)-1～3℃之間(jian)，不經任何處(chu)理過(guo)程，其(qi)蒸發(fa)器(qi)放置于室(shi)內(nei)(nei)，由風(feng)(feng)(feng)機直(zhi)接在(zai)室(shi)內(nei)(nei)吹出7～10℃的(de)冷(leng)風(feng)(feng)(feng)，若人直(zhi)接在(zai)送(song)風(feng)(feng)(feng)口的(de)送(song)風(feng)(feng)(feng)范圍(wei)內(nei)(nei)工作或(huo)做其(qi)他(ta)(ta)活動，就會(hui)有冷(leng)風(feng)(feng)(feng)刺(ci)骨的(de)感(gan)覺，人若長時間(jian)在(zai)此(ci)環境下逗留，很容(rong)易患上感(gan)冒(mao)或(huo)其(qi)他(ta)(ta)空(kong)(kong)調(diao)病。
3、風(feng)(feng)冷(leng)(leng)式冷(leng)(leng)水機組(zu)(zu)的(de)(de)末端系統的(de)(de)送(song)、回(hui)(hui)風(feng)(feng)口(kou)分開，在設計過程中，可以調節風(feng)(feng)冷(leng)(leng)式冷(leng)(leng)水機組(zu)(zu)的(de)(de)末端系統送(song)、回(hui)(hui)風(feng)(feng)口(kou)的(de)(de)位(wei)置，以達(da)到不(bu)同(tong)形狀的(de)(de)房(fang)(fang)間(jian)(jian)都有(you)送(song)風(feng)(feng)均勻(yun)的(de)(de)效果，空氣的(de)(de)氣流組(zu)(zu)織合(he)理化，使房(fang)(fang)間(jian)(jian)內不(bu)存(cun)在送(song)風(feng)(feng)死(si)角(jiao)(jiao)；而全氟一(yi)拖多(duo)小型空調系統的(de)(de)送(song)、回(hui)(hui)風(feng)(feng)口(kou)基本(ben)都是(shi)一(yi)體(ti)(ti)的(de)(de)，很難(nan)適應不(bu)同(tong)房(fang)(fang)間(jian)(jian)形狀的(de)(de)變化，這種一(yi)體(ti)(ti)化的(de)(de)送(song)、回(hui)(hui)風(feng)(feng)口(kou)只(zhi)適用于正方形或圓形的(de)(de)房(fang)(fang)間(jian)(jian)，而其他形狀的(de)(de)房(fang)(fang)間(jian)(jian)就存(cun)在氣流死(si)角(jiao)(jiao)，造(zao)成房(fang)(fang)間(jian)(jian)內溫(wen)度(du)不(bu)均勻(yun)的(de)(de)后果。
4、風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水(shui)(shui)機(ji)組系(xi)統的(de)(de)初投資(zi)低，維(wei)修(xiu)(xiu)、保養方便(bian)，而且(qie)費(fei)(fei)用(yong)低，風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水(shui)(shui)機(ji)組系(xi)統的(de)(de)設(she)備(bei)費(fei)(fei)和(he)安裝費(fei)(fei)都(dou)比較便(bian)宜，風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水(shui)(shui)機(ji)組系(xi)統的(de)(de)供(gong)、回水(shui)(shui)管(guan)(guan)(guan)道(dao)都(dou)屬于低壓流體輸送管(guan)(guan)(guan)道(dao)，其管(guan)(guan)(guan)道(dao)材質為(wei)普(pu)通(tong)熱鍍鋅鋼(gang)管(guan)(guan)(guan)，閥門為(wei)普(pu)通(tong)焊接法蘭(lan)閥門或(huo)絲扣閥門，在(zai)市場上很容易購買，而且(qie)價格便(bian)宜，維(wei)修(xiu)(xiu)操作也比較簡單；而全氟一拖(tuo)多(duo)小(xiao)(xiao)型空調系(xi)統的(de)(de)初投資(zi)高，其設(she)備(bei)費(fei)(fei)和(he)安裝費(fei)(fei)相比萬(wan)德風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水(shui)(shui)機(ji)組系(xi)統要高的(de)(de)多(duo)，全氟一拖(tuo)多(duo)小(xiao)(xiao)型空調系(xi)統的(de)(de)氟路管(guan)(guan)(guan)道(dao)屬于高壓管(guan)(guan)(guan)道(dao)，其管(guan)(guan)(guan)道(dao)材質為(wei)紫(zi)銅管(guan)(guan)(guan)，閥門為(wei)黃銅材質，購買需到專(zhuan)業制冷(leng)(leng)(leng)配件(jian)商(shang)店，價格也高，維(wei)修(xiu)(xiu)工作需要專(zhuan)業制冷(leng)(leng)(leng)釬(han)焊人員進行，困難程度也較高，而且(qie)維(wei)修(xiu)(xiu)時需要把整(zheng)個室內系(xi)統的(de)(de)氟利(li)昂(ang)排出(chu)，維(wei)修(xiu)(xiu)完(wan)畢后再重新(xin)灌注大量新(xin)氟利(li)昂(ang)，更加提高了維(wei)修(xiu)(xiu)的(de)(de)費(fei)(fei)用(yong)。
5、風冷(leng)式(shi)冷(leng)水機(ji)組系(xi)統(tong)(tong)的(de)室(shi)內(nei)系(xi)統(tong)(tong)可以(yi)(yi)連接(jie)到市(shi)政熱(re)源系(xi)統(tong)(tong)或鍋爐系(xi)統(tong)(tong)上，在(zai)冬(dong)季(ji)進(jin)行供(gong)(gong)(gong)(gong)(gong)熱(re)，使(shi)(shi)用(yong)風冷(leng)式(shi)冷(leng)水機(ji)組系(xi)統(tong)(tong)的(de)室(shi)內(nei)系(xi)統(tong)(tong)供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)，室(shi)內(nei)不(bu)干燥，熱(re)風均勻穩定，不(bu)受(shou)外界氣候條件的(de)影響，而(er)且風冷(leng)式(shi)冷(leng)水機(ji)組系(xi)統(tong)(tong)可以(yi)(yi)在(zai)供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)期(qi)(qi)前(qian)(qian)后(hou)的(de)過度(du)季(ji)節啟動熱(re)泵功(gong)能，對(dui)室(shi)內(nei)進(jin)行供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)；而(er)全氟一拖多(duo)小型空調(diao)系(xi)統(tong)(tong)只能在(zai)供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)期(qi)(qi)前(qian)(qian)后(hou)的(de)過度(du)季(ji)節對(dui)室(shi)內(nei)進(jin)行供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)，在(zai)供(gong)(gong)(gong)(gong)(gong)暖(nuan)(nuan)(nuan)期(qi)(qi)間，若室(shi)外氣溫低于-5℃，其熱(re)泵效(xiao)(xiao)率急(ji)劇下降，就是室(shi)外溫度(du)越(yue)低，其機(ji)組的(de)制熱(re)量越(yue)小，這就不(bu)能滿(man)足冬(dong)季(ji)供(gong)(gong)(gong)(gong)(gong)熱(re)的(de)穩定性(xing)，所以(yi)(yi)全氟一拖多(duo)小型空調(diao)系(xi)統(tong)(tong)在(zai)冬(dong)季(ji)還需要傳統(tong)(tong)的(de)暖(nuan)(nuan)(nuan)氣系(xi)統(tong)(tong)對(dui)室(shi)內(nei)進(jin)行供(gong)(gong)(gong)(gong)(gong)熱(re)，這樣既(ji)增加了投資的(de)費用(yong)，又占用(yong)了室(shi)內(nei)有效(xiao)(xiao)的(de)使(shi)(shi)用(yong)面積(ji)。
6、風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機組系(xi)統(tong)(tong)(tong)(tong)的室內系(xi)統(tong)(tong)(tong)(tong)內流動的是(shi)水(shui)(shui)，而(er)且(qie)系(xi)統(tong)(tong)(tong)(tong)屬于低壓系(xi)統(tong)(tong)(tong)(tong)（1～5㎏/cm2），不容(rong)易(yi)產(chan)(chan)生(sheng)(sheng)(sheng)泄(xie)漏，即使萬一產(chan)(chan)生(sheng)(sheng)(sheng)泄(xie)漏，水(shui)(shui)對(dui)人體也沒(mei)有任何危害性（風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機組系(xi)統(tong)(tong)(tong)(tong)的氟(fu)路(lu)系(xi)統(tong)(tong)(tong)(tong)全部都置于室外風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機組內）；而(er)全氟(fu)一拖多小型(xing)空調系(xi)統(tong)(tong)(tong)(tong)的室內系(xi)統(tong)(tong)(tong)(tong)內流動的全部是(shi)氟(fu)利(li)(li)昂(ang)，而(er)且(qie)系(xi)統(tong)(tong)(tong)(tong)屬于高壓系(xi)統(tong)(tong)(tong)(tong)（4～22㎏/cm2），很容(rong)易(yi)產(chan)(chan)生(sheng)(sheng)(sheng)泄(xie)漏，一旦(dan)產(chan)(chan)生(sheng)(sheng)(sheng)泄(xie)漏，氟(fu)利(li)(li)昂(ang)遇明火就產(chan)(chan)生(sheng)(sheng)(sheng)有毒(du)氣體——光(guang)氣，對(dui)人體造成生(sheng)(sheng)(sheng)命危險。
7、風冷式(shi)冷水(shui)機組(zu)系統(tong)(tong)可以(yi)用于面積大、建(jian)筑(zhu)檐高(gao)高(gao)的(de)(de)(de)(de)建(jian)筑(zhu)，根(gen)據室內系統(tong)(tong)的(de)(de)(de)(de)管(guan)(guan)道(dao)(dao)(dao)的(de)(de)(de)(de)長短(duan)、管(guan)(guan)徑的(de)(de)(de)(de)大小以(yi)及(ji)室內設(she)備(bei)的(de)(de)(de)(de)多(duo)少來(lai)計算管(guan)(guan)道(dao)(dao)(dao)阻力的(de)(de)(de)(de)大小，選(xuan)擇(ze)適當揚程、流量的(de)(de)(de)(de)水(shui)泵，能夠保證各管(guan)(guan)道(dao)(dao)(dao)內冷水(shui)的(de)(de)(de)(de)流量，風冷式(shi)冷水(shui)機組(zu)系統(tong)(tong)的(de)(de)(de)(de)安裝不(bu)(bu)受管(guan)(guan)道(dao)(dao)(dao)的(de)(de)(de)(de)長短(duan)、面積的(de)(de)(de)(de)大小、建(jian)筑(zhu)檐高(gao)等因素的(de)(de)(de)(de)影響；而全氟一拖多(duo)小型空調系統(tong)(tong)的(de)(de)(de)(de)紫(zi)銅(tong)管(guan)(guan)道(dao)(dao)(dao)系統(tong)(tong)最(zui)長只能做到35～40m長，否則氟利昂系統(tong)(tong)就不(bu)(bu)能良好循環，設(she)備(bei)就不(bu)(bu)能正常運轉，而且(qie)即使紫(zi)銅(tong)管(guan)(guan)道(dao)(dao)(dao)系統(tong)(tong)在40m長度(du)范圍(wei)內，其工作(zuo)效率也隨著長度(du)的(de)(de)(de)(de)增加而下(xia)降。
8、風冷(leng)式冷(leng)水(shui)機組系統的(de)(de)室內系統的(de)(de)冷(leng)凝水(shui)管通過0.3～0.6%的(de)(de)坡向進行排(pai)放(fang)冷(leng)凝水(shui)，依靠水(shui)自身重(zhong)力的(de)(de)流動來排(pai)放(fang)，原理簡(jian)單，故(gu)障(zhang)率(lv)低；而全氟(fu)一拖(tuo)多小(xiao)型(xing)空調系統的(de)(de)室內系統的(de)(de)冷(leng)凝水(shui)是(shi)通過微型(xing)水(shui)泵的(de)(de)抽吸排(pai)放(fang)，這種微型(xing)水(shui)泵隱藏于室內機內部，故(gu)障(zhang)率(lv)很高(gao)，一旦(dan)發(fa)生故(gu)障(zhang)，就會出現冷(leng)凝水(shui)尿頂現象，影響裝修(xiu)的(de)(de)美觀，而且維修(xiu)相當困(kun)難。
9、風(feng)(feng)冷(leng)式(shi)冷(leng)水機(ji)(ji)組系統(tong)可根據室內風(feng)(feng)機(ji)(ji)盤管(guan)大(da)小(xiao)(xiao)(xiao)(xiao)，通過(guo)管(guan)徑及閥門來(lai)調節通過(guo)每臺(tai)風(feng)(feng)機(ji)(ji)盤管(guan)的(de)水流量的(de)大(da)小(xiao)(xiao)(xiao)(xiao)，以保證(zheng)每個房(fang)間內的(de)溫(wen)度相(xiang)同；而全氟一拖(tuo)多(duo)小(xiao)(xiao)(xiao)(xiao)型空調系統(tong)的(de)室內機(ji)(ji)雖然有(you)大(da)有(you)小(xiao)(xiao)(xiao)(xiao)，但是(shi)其氟路系統(tong)均(jun)分器分向(xiang)每臺(tai)室內機(ji)(ji)的(de)氟利昂的(de)流量是(shi)大(da)致相(xiang)等(deng)的(de)，這(zhe)樣(yang)就(jiu)造(zao)成了(le)小(xiao)(xiao)(xiao)(xiao)的(de)室內機(ji)(ji)蒸發溫(wen)度低，其送(song)(song)風(feng)(feng)溫(wen)度也低，大(da)的(de)室內機(ji)(ji)蒸發溫(wen)度高，其送(song)(song)風(feng)(feng)溫(wen)度也高，就(jiu)形成了(le)小(xiao)(xiao)(xiao)(xiao)房(fang)間冷(leng)、大(da)房(fang)間熱的(de)冷(leng)熱不均(jun)現象(xiang)。
10、風冷(leng)式冷(leng)水機組是(shi)由多個模塊(kuai)組成(cheng)的，其中(zhong)(zhong)一(yi)個模塊(kuai)發生(sheng)故(gu)障進(jin)行維(wei)修(xiu)時，其他模塊(kuai)照常正常運轉，進(jin)行制(zhi)冷(leng)或制(zhi)熱(re)工作(zuo)，不(bu)影響整體(ti)的中(zhong)(zhong)央空(kong)調(diao)(diao)效果；而(er)全氟(fu)一(yi)拖多小型空(kong)調(diao)(diao)系統一(yi)旦發生(sheng)故(gu)障，就得(de)全部停機維(wei)修(xiu)，空(kong)調(diao)(diao)暫時不(bu)能使用(yong)。
11、風(feng)冷(leng)(leng)式冷(leng)(leng)水機(ji)組系統可(ke)以根據室內(nei)冷(leng)(leng)熱負(fu)荷的的變化，由電腦控制自(zi)動調節(jie)(jie)投(tou)入運(yun)轉模塊的數量，以達到(dao)節(jie)(jie)能(neng)的目的；全(quan)氟一(yi)拖多(duo)小型空調系統則始終全(quan)部投(tou)入運(yun)轉，不能(neng)實(shi)現節(jie)(jie)能(neng)的目的。
12、風冷(leng)式冷(leng)水機組系統(tong)集中(zhong)控制，電腦值(zhi)班，實現(xian)了無人(ren)管(guan)理(li)(li)，大(da)大(da)節省了人(ren)力(li)(li)、物(wu)力(li)(li)；全氟一拖多小型(xing)空調系統(tong)分散管(guan)理(li)(li)，投(tou)入(ru)大(da)，人(ren)力(li)(li)多，造成了人(ren)力(li)(li)、物(wu)力(li)(li)的浪費。 |
