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式主要有兩(liang)種(zhong)：
1、采用恒溫恒濕空調機組（自帶制冷機）的全空氣系統
恒溫恒濕空(kong)調(diao)機(ji)(ji)組宜用在(zai)精度Δt=±1℃，Δφ=10%的(de)(de)空(kong)調(diao)房間(jian)內。在(zai)夏季，機(ji)(ji)組對濕度的(de)(de)控(kong)(kong)制(zhi)能力(li)較(jiao)低，因此機(ji)(ji)組冷量的(de)(de)調(diao)節一般(ban)只(zhi)有兩檔(dang)或三檔(dang)。因此只(zhi)適(shi)用于(yu)濕負荷變化(hua)比較(jiao)小(xiao)的(de)(de)空(kong)調(diao)房間(jian)。如果空(kong)調(diao)房間(jian)對濕度控(kong)(kong)制(zhi)要求不高(gao)，這種(zhong)機(ji)(ji)組可用于(yu)溫度控(kong)(kong)制(zhi)要求較(jiao)高(gao)（如±0.5℃）的(de)(de)場(chang)合。但如果恒溫恒濕空(kong)調(diao)機(ji)(ji)組采(cai)用變頻控(kong)(kong)制(zhi)壓(ya)縮(suo)機(ji)(ji)的(de)(de)轉速(su)，則濕度的(de)(de)控(kong)(kong)制(zhi)精度可達到±2%。
2、以冷凍水作介質的全空氣系統
以冷(leng)(leng)(leng)凍水作冷(leng)(leng)(leng)卻介(jie)質的(de)(de)定風(feng)量全(quan)空氣(qi)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)恒溫恒濕(shi)(shi)空調(diao)系(xi)(xi)統(tong)(tong)(tong)都采用(yong)(yong)再(zai)熱式(shi)系(xi)(xi)統(tong)(tong)(tong)。在夏(xia)季(ji)，通過調(diao)節再(zai)加熱量以控(kong)制溫度，調(diao)節空氣(qi)冷(leng)(leng)(leng)卻設(she)(she)(she)(she)備(bei)(bei)的(de)(de)冷(leng)(leng)(leng)量以控(kong)制濕(shi)(shi)度。空氣(qi)冷(leng)(leng)(leng)卻設(she)(she)(she)(she)備(bei)(bei)如(ru)采用(yong)(yong)表(biao)冷(leng)(leng)(leng)器的(de)(de)系(xi)(xi)統(tong)(tong)(tong)，適宜用(yong)(yong)于濕(shi)(shi)度變化(hua)不(bu)大的(de)(de)場合。全(quan)年濕(shi)(shi)度變化(hua)較大或濕(shi)(shi)度控(kong)制精度較高(gao)的(de)(de)場所，熱濕(shi)(shi)處理設(she)(she)(she)(she)備(bei)(bei)宜采用(yong)(yong)噴(pen)水室(shi)。噴(pen)水室(shi)都是(shi)開(kai)式(shi)的(de)(de)，當冷(leng)(leng)(leng)凍水系(xi)(xi)統(tong)(tong)(tong)主要用(yong)(yong)于噴(pen)水室(shi)設(she)(she)(she)(she)備(bei)(bei)，冷(leng)(leng)(leng)凍水系(xi)(xi)統(tong)(tong)(tong)可以是(shi)開(kai)式(shi)的(de)(de)；當系(xi)(xi)統(tong)(tong)(tong)中(zhong)既有噴(pen)水室(shi)又有表(biao)冷(leng)(leng)(leng)器、風(feng)機盤(pan)管(guan)等設(she)(she)(she)(she)備(bei)(bei)，冷(leng)(leng)(leng)凍水系(xi)(xi)統(tong)(tong)(tong)應當優(you)先采用(yong)(yong)閉(bi)式(shi)系(xi)(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(yong)的形(xing)式，它自帶制冷機，由制冷系統、電(dian)加熱器(qi)、加濕器(qi)及溫(wen)濕度(du)自動(dong)控制元件等幾部分組成，其具體結構(gou)包括：
干(gan)濕(shi)(shi)球(qiu)溫度控(kong)制(zhi)器(qi)(qi)(qi)、電加熱(re)器(qi)(qi)(qi)、通(tong)風(feng)機、電極加濕(shi)(shi)器(qi)(qi)(qi)、蒸(zheng)發器(qi)(qi)(qi)、壓(ya)(ya)縮機、冷凝(ning)器(qi)(qi)(qi)、貯液器(qi)(qi)(qi)、壓(ya)(ya)力控(kong)制(zhi)器(qi)(qi)(qi)、過濾器(qi)(qi)(qi)、節流(liu)機構；如果是熱(re)泵(beng)式恒溫恒濕(shi)(shi)空調(diao)機組，其制(zhi)冷系(xi)統中還會(hui)加一個四通(tong)轉(zhuan)向閥，使冷凝(ning)器(qi)(qi)(qi)與蒸(zheng)發器(qi)(qi)(qi)互(hu)相轉(zhuan)換(huan)。
