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(de)形式主(zhu)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(wen)恒(heng)濕(shi)(shi)空(kong)(kong)調機(ji)(ji)(ji)組(zu)宜用在精(jing)度Δt=±1℃，Δφ=10%的(de)空(kong)(kong)調房間內。在夏季，機(ji)(ji)(ji)組(zu)對(dui)濕(shi)(shi)度的(de)控(kong)制(zhi)能(neng)力較(jiao)低，因此(ci)機(ji)(ji)(ji)組(zu)冷量的(de)調節(jie)一(yi)般只(zhi)(zhi)有兩檔或三檔。因此(ci)只(zhi)(zhi)適(shi)用于濕(shi)(shi)負荷(he)變(bian)化比較(jiao)小的(de)空(kong)(kong)調房間。如果(guo)空(kong)(kong)調房間對(dui)濕(shi)(shi)度控(kong)制(zhi)要求不高(gao)，這種機(ji)(ji)(ji)組(zu)可用于溫(wen)度控(kong)制(zhi)要求較(jiao)高(gao)（如±0.5℃）的(de)場合(he)。但如果(guo)恒(heng)溫(wen)恒(heng)濕(shi)(shi)空(kong)(kong)調機(ji)(ji)(ji)組(zu)采用變(bian)頻控(kong)制(zhi)壓縮機(ji)(ji)(ji)的(de)轉速，則(ze)濕(shi)(shi)度的(de)控(kong)制(zhi)精(jing)度可達到±2%。
2、以冷凍水作介質的全空氣系統
以冷(leng)(leng)(leng)(leng)凍(dong)(dong)水(shui)(shui)作冷(leng)(leng)(leng)(leng)卻介質(zhi)的(de)定風量(liang)全空氣(qi)(qi)系(xi)(xi)統(tong)的(de)恒(heng)溫恒(heng)濕空調(diao)系(xi)(xi)統(tong)都采(cai)用(yong)(yong)再熱(re)式系(xi)(xi)統(tong)。在(zai)夏季，通過調(diao)節(jie)再加熱(re)量(liang)以控(kong)制(zhi)溫度(du)(du)，調(diao)節(jie)空氣(qi)(qi)冷(leng)(leng)(leng)(leng)卻設備(bei)(bei)的(de)冷(leng)(leng)(leng)(leng)量(liang)以控(kong)制(zhi)濕度(du)(du)。空氣(qi)(qi)冷(leng)(leng)(leng)(leng)卻設備(bei)(bei)如采(cai)用(yong)(yong)表冷(leng)(leng)(leng)(leng)器(qi)的(de)系(xi)(xi)統(tong)，適宜用(yong)(yong)于(yu)濕度(du)(du)變化(hua)不大的(de)場(chang)合。全年濕度(du)(du)變化(hua)較大或濕度(du)(du)控(kong)制(zhi)精度(du)(du)較高的(de)場(chang)所(suo)，熱(re)濕處理設備(bei)(bei)宜采(cai)用(yong)(yong)噴(pen)水(shui)(shui)室(shi)(shi)。噴(pen)水(shui)(shui)室(shi)(shi)都是(shi)開式的(de)，當冷(leng)(leng)(leng)(leng)凍(dong)(dong)水(shui)(shui)系(xi)(xi)統(tong)主(zhu)要(yao)用(yong)(yong)于(yu)噴(pen)水(shui)(shui)室(shi)(shi)設備(bei)(bei)，冷(leng)(leng)(leng)(leng)凍(dong)(dong)水(shui)(shui)系(xi)(xi)統(tong)可以是(shi)開式的(de)；當系(xi)(xi)統(tong)中既(ji)有噴(pen)水(shui)(shui)室(shi)(shi)又有表冷(leng)(leng)(leng)(leng)器(qi)、風機盤管等設備(bei)(bei)，冷(leng)(leng)(leng)(leng)凍(dong)(dong)水(shui)(shui)系(xi)(xi)統(tong)應(ying)當優先采(cai)用(yong)(yong)閉式系(xi)(xi)統(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(tong)常用(yong)的形式，它自帶(dai)制冷機，由制冷系統(tong)、電加(jia)(jia)熱器(qi)、加(jia)(jia)濕(shi)器(qi)及(ji)溫(wen)濕(shi)度自動控制元件等幾部(bu)分組成，其(qi)具體(ti)結構(gou)包(bao)括(kuo)：
干(gan)濕(shi)球溫度控制(zhi)器(qi)、電加熱(re)器(qi)、通(tong)風機(ji)(ji)(ji)、電極加濕(shi)器(qi)、蒸發器(qi)、壓縮(suo)機(ji)(ji)(ji)、冷(leng)凝器(qi)、貯液器(qi)、壓力控制(zhi)器(qi)、過濾器(qi)、節(jie)流(liu)機(ji)(ji)(ji)構；如(ru)果是熱(re)泵(beng)式恒溫恒濕(shi)空調機(ji)(ji)(ji)組(zu)，其制(zhi)冷(leng)系統中還會(hui)加一個(ge)四通(tong)轉向(xiang)閥，使冷(leng)凝器(qi)與(yu)蒸發器(qi)互相轉換。
