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，恒溫恒濕空調系統的形(xing)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(heng)溫恒(heng)濕(shi)空(kong)調(diao)(diao)(diao)(diao)機(ji)(ji)組(zu)(zu)宜(yi)用(yong)在精(jing)度(du)(du)Δt=±1℃，Δφ=10%的(de)空(kong)調(diao)(diao)(diao)(diao)房間內。在夏季，機(ji)(ji)組(zu)(zu)對濕(shi)度(du)(du)的(de)控(kong)制能力較低，因此(ci)機(ji)(ji)組(zu)(zu)冷量的(de)調(diao)(diao)(diao)(diao)節一般只有(you)兩檔(dang)或(huo)三檔(dang)。因此(ci)只適用(yong)于濕(shi)負荷變(bian)化比較小的(de)空(kong)調(diao)(diao)(diao)(diao)房間。如果(guo)空(kong)調(diao)(diao)(diao)(diao)房間對濕(shi)度(du)(du)控(kong)制要求(qiu)不(bu)高，這種機(ji)(ji)組(zu)(zu)可用(yong)于溫度(du)(du)控(kong)制要求(qiu)較高（如±0.5℃）的(de)場(chang)合。但如果(guo)恒(heng)溫恒(heng)濕(shi)空(kong)調(diao)(diao)(diao)(diao)機(ji)(ji)組(zu)(zu)采用(yong)變(bian)頻控(kong)制壓縮(suo)機(ji)(ji)的(de)轉速，則(ze)濕(shi)度(du)(du)的(de)控(kong)制精(jing)度(du)(du)可達到±2%。
2、以冷凍水作介質的全空氣系統
以冷(leng)凍(dong)水(shui)(shui)作冷(leng)卻(que)介質的(de)定風(feng)量(liang)(liang)全空(kong)氣系(xi)(xi)統(tong)(tong)的(de)恒(heng)溫恒(heng)濕(shi)(shi)(shi)空(kong)調系(xi)(xi)統(tong)(tong)都(dou)采用(yong)再熱式(shi)系(xi)(xi)統(tong)(tong)。在夏(xia)季(ji)，通過調節再加熱量(liang)(liang)以控(kong)制(zhi)溫度(du)，調節空(kong)氣冷(leng)卻(que)設(she)備(bei)(bei)的(de)冷(leng)量(liang)(liang)以控(kong)制(zhi)濕(shi)(shi)(shi)度(du)。空(kong)氣冷(leng)卻(que)設(she)備(bei)(bei)如采用(yong)表冷(leng)器(qi)的(de)系(xi)(xi)統(tong)(tong)，適宜用(yong)于濕(shi)(shi)(shi)度(du)變化不大的(de)場合。全年濕(shi)(shi)(shi)度(du)變化較大或濕(shi)(shi)(shi)度(du)控(kong)制(zhi)精度(du)較高(gao)的(de)場所，熱濕(shi)(shi)(shi)處(chu)理設(she)備(bei)(bei)宜采用(yong)噴水(shui)(shui)室(shi)(shi)。噴水(shui)(shui)室(shi)(shi)都(dou)是(shi)開式(shi)的(de)，當冷(leng)凍(dong)水(shui)(shui)系(xi)(xi)統(tong)(tong)主要用(yong)于噴水(shui)(shui)室(shi)(shi)設(she)備(bei)(bei)，冷(leng)凍(dong)水(shui)(shui)系(xi)(xi)統(tong)(tong)可(ke)以是(shi)開式(shi)的(de)；當系(xi)(xi)統(tong)(tong)中既有噴水(shui)(shui)室(shi)(shi)又有表冷(leng)器(qi)、風(feng)機盤管(guan)等設(she)備(bei)(bei)，冷(leng)凍(dong)水(shui)(shui)系(xi)(xi)統(tong)(tong)應當優先采用(yong)閉式(shi)系(xi)(xi)統(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(xi)統常(chang)用的形式，它自帶制(zhi)冷機，由制(zhi)冷系(xi)統、電加熱(re)器(qi)、加濕器(qi)及溫濕度自動控制(zhi)元件等幾部分組成，其具體結構(gou)包括：
干濕球(qiu)溫度控(kong)制器(qi)(qi)(qi)、電加(jia)熱器(qi)(qi)(qi)、通風機(ji)、電極加(jia)濕器(qi)(qi)(qi)、蒸(zheng)(zheng)發器(qi)(qi)(qi)、壓縮機(ji)、冷(leng)凝(ning)器(qi)(qi)(qi)、貯液器(qi)(qi)(qi)、壓力控(kong)制器(qi)(qi)(qi)、過濾器(qi)(qi)(qi)、節流(liu)機(ji)構(gou)；如果是熱泵式恒溫恒濕空調(diao)機(ji)組，其制冷(leng)系統(tong)中(zhong)還(huan)會加(jia)一個(ge)四通轉(zhuan)向(xiang)閥，使冷(leng)凝(ning)器(qi)(qi)(qi)與(yu)蒸(zheng)(zheng)發器(qi)(qi)(qi)互相轉(zhuan)換。
