一、恒溫恒濕空調系統的形式有哪兩種
恒溫恒濕空調可以對室內溫、濕度波動和區域偏差進行嚴格的控制，在很多領域都有應用，恒溫恒濕空調系統(tong)的形式(shi)主要有兩種：
1、采用恒溫恒濕空調機組（自帶制冷機）的全空氣系統
恒溫(wen)恒濕(shi)空調機(ji)組(zu)宜用(yong)在精度(du)(du)Δt=±1℃，Δφ=10%的空調房(fang)(fang)間(jian)內(nei)。在夏季，機(ji)組(zu)對(dui)濕(shi)度(du)(du)的控制能力較低，因此(ci)機(ji)組(zu)冷量的調節一般只有兩檔(dang)或三檔(dang)。因此(ci)只適用(yong)于濕(shi)負荷變(bian)化比較小的空調房(fang)(fang)間(jian)。如果空調房(fang)(fang)間(jian)對(dui)濕(shi)度(du)(du)控制要(yao)(yao)求不高(gao)，這種機(ji)組(zu)可用(yong)于溫(wen)度(du)(du)控制要(yao)(yao)求較高(gao)（如±0.5℃）的場合。但(dan)如果恒溫(wen)恒濕(shi)空調機(ji)組(zu)采用(yong)變(bian)頻控制壓縮(suo)機(ji)的轉(zhuan)速，則濕(shi)度(du)(du)的控制精度(du)(du)可達到(dao)±2%。
2、以冷凍水作介質的全空氣系統
以(yi)冷(leng)凍(dong)水(shui)作(zuo)冷(leng)卻介質(zhi)的(de)(de)定(ding)風量(liang)(liang)全空氣(qi)(qi)系(xi)統(tong)(tong)(tong)的(de)(de)恒溫恒濕(shi)空調系(xi)統(tong)(tong)(tong)都采(cai)用(yong)(yong)再(zai)熱(re)(re)(re)式系(xi)統(tong)(tong)(tong)。在夏季(ji)，通過調節再(zai)加熱(re)(re)(re)量(liang)(liang)以(yi)控(kong)制(zhi)(zhi)溫度(du)(du)(du)，調節空氣(qi)(qi)冷(leng)卻設(she)(she)備(bei)的(de)(de)冷(leng)量(liang)(liang)以(yi)控(kong)制(zhi)(zhi)濕(shi)度(du)(du)(du)。空氣(qi)(qi)冷(leng)卻設(she)(she)備(bei)如采(cai)用(yong)(yong)表(biao)冷(leng)器(qi)的(de)(de)系(xi)統(tong)(tong)(tong)，適宜用(yong)(yong)于(yu)濕(shi)度(du)(du)(du)變化不大的(de)(de)場合。全年濕(shi)度(du)(du)(du)變化較(jiao)大或濕(shi)度(du)(du)(du)控(kong)制(zhi)(zhi)精度(du)(du)(du)較(jiao)高(gao)的(de)(de)場所，熱(re)(re)(re)濕(shi)處理設(she)(she)備(bei)宜采(cai)用(yong)(yong)噴(pen)水(shui)室(shi)(shi)。噴(pen)水(shui)室(shi)(shi)都是(shi)開(kai)式的(de)(de)，當(dang)冷(leng)凍(dong)水(shui)系(xi)統(tong)(tong)(tong)主要(yao)用(yong)(yong)于(yu)噴(pen)水(shui)室(shi)(shi)設(she)(she)備(bei)，冷(leng)凍(dong)水(shui)系(xi)統(tong)(tong)(tong)可(ke)以(yi)是(shi)開(kai)式的(de)(de)；當(dang)系(xi)統(tong)(tong)(tong)中既(ji)有噴(pen)水(shui)室(shi)(shi)又有表(biao)冷(leng)器(qi)、風機盤管(guan)等設(she)(she)備(bei)，冷(leng)凍(dong)水(shui)系(xi)統(tong)(tong)(tong)應當(dang)優先(xian)采(cai)用(yong)(yong)閉式系(xi)統(tong)(tong)(tong)。
二、恒溫恒濕空調機組分幾部分
恒溫恒濕空調機組是恒溫恒濕空調系統常(chang)用的形式，它自(zi)帶制冷機(ji)，由制冷系統、電加(jia)熱器、加(jia)濕(shi)器及溫濕(shi)度自(zi)動控制元(yuan)件等(deng)幾(ji)部分組成，其具體結構包括(kuo)：
干濕(shi)(shi)球溫度控(kong)制(zhi)(zhi)器(qi)、電加熱器(qi)、通風機、電極加濕(shi)(shi)器(qi)、蒸發(fa)器(qi)、壓(ya)縮機、冷凝(ning)器(qi)、貯液器(qi)、壓(ya)力控(kong)制(zhi)(zhi)器(qi)、過濾器(qi)、節流機構(gou)；如果是(shi)熱泵式恒(heng)(heng)溫恒(heng)(heng)濕(shi)(shi)空調機組，其(qi)制(zhi)(zhi)冷系(xi)統中還會(hui)加一個四通轉向(xiang)閥，使(shi)冷凝(ning)器(qi)與蒸發(fa)器(qi)互相(xiang)轉換。
