雖然(ran)在商業(ye)建(jian)(jian)筑(zhu)(zhu)與多種居住(zhu)房的(de)(de)被(bei)動(dong)消防(fang)中(zhong)(zhong)，防(fang)火(huo)(huo)閥是(shi)關鍵組件，但(dan)在對建(jian)(jian)筑(zhu)(zhu)和其(qi)(qi)居住(zhu)者(zhe)的(de)(de)安全保護(hu)中(zhong)(zhong)，很多管理者(zhe)沒有(you)意(yi)識到防(fang)火(huo)(huo)閥的(de)(de)作用以及規定時間間隔內，防(fang)火(huo)(huo)閥的(de)(de)檢測(ce)、清潔及維護(hu)的(de)(de)重要(yao)意(yi)義。在商業(ye)建(jian)(jian)筑(zhu)(zhu)中(zhong)(zhong)的(de)(de)建(jian)(jian)造中(zhong)(zhong)我們(men)總會遇到一些麻煩(fan)，試(shi)圖在能源效率與室內空(kong)氣(qi)質量之間尋求平(ping)衡就(jiu)是(shi)其(qi)(qi)中(zhong)(zhong)。大多商業(ye)建(jian)(jian)筑(zhu)(zhu)通(tong)(tong)(tong)過機械通(tong)(tong)(tong)風(feng)或(huo)(huo)空(kong)調系(xi)(xi)統解決，能夠測(ce)量和控制整個建(jian)(jian)筑(zhu)(zhu)的(de)(de)空(kong)氣(qi)變(bian)化(hua)。在通(tong)(tong)(tong)風(feng)管道系(xi)(xi)統的(de)(de)安裝上就(jiu)存在上面(mian)提(ti)到的(de)(de)問(wen)題———如(ru)何在延(yan)遲或(huo)(huo)阻止火(huo)(huo)災蔓延(yan)的(de)(de)建(jian)(jian)筑(zhu)(zhu)防(fang)火(huo)(huo)分隔與所允許(xu)空(kong)氣(qi)自由(you)流通(tong)(tong)(tong)的(de)(de)需要(yao)之間達到平(ping)衡。滿足空(kong)氣(qi)自由(you)流通(tong)(tong)(tong)需要(yao)不可避免地再引(yin)入一條(tiao)通(tong)(tong)(tong)道，而這卻加快了火(huo)(huo)勢(shi)的(de)(de)蔓延(yan)———利用通(tong)(tong)(tong)風(feng)管道系(xi)(xi)統使用的(de)(de)通(tong)(tong)(tong)道。毫(hao)無(wu)疑問(wen)，這中(zhong)(zhong)斷了防(fang)火(huo)(huo)分隔，充(chong)當了建(jian)(jian)筑(zhu)(zhu)被(bei)動(dong)消防(fang)護(hu)面(mian)的(de)(de)“裂口(kou)”。

在了解空(kong)調(diao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機的(de)(de)工(gong)作(zuo)原理之前，先來(lai)認(ren)識下(xia)空(kong)調(diao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機的(de)(de)工(gong)作(zuo)回(hui)(hui)路。空(kong)調(diao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機的(de)(de)工(gong)作(zuo)回(hui)(hui)路分為蒸(zheng)發(fa)(fa)(fa)區和冷(leng)(leng)(leng)凝區，空(kong)調(diao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機在空(kong)調(diao)制(zhi)冷(leng)(leng)(leng)劑回(hui)(hui)路中起壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)驅動(dong)制(zhi)冷(leng)(leng)(leng)劑的(de)(de)作(zuo)用(yong)。空(kong)調(diao)制(zhi)冷(leng)(leng)(leng)時，中央(yang)空(kong)調(diao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機把制(zhi)冷(leng)(leng)(leng)劑從(cong)(cong)低(di)壓(ya)(ya)(ya)(ya)(ya)區抽取來(lai)經(jing)(jing)緊縮(suo)(suo)(suo)后送到(dao)高壓(ya)(ya)(ya)(ya)(ya)區冷(leng)(leng)(leng)卻凝結，經(jing)(jing)過(guo)散熱(re)(re)(re)片(pian)分發(fa)(fa)(fa)出熱(re)(re)(re)量到(dao)空(kong)氣(qi)中，制(zhi)冷(leng)(leng)(leng)劑也從(cong)(cong)氣(qi)態(tai)變成液(ye)態(tai)，壓(ya)(ya)(ya)(ya)(ya)力升高。制(zhi)冷(leng)(leng)(leng)劑再(zai)從(cong)(cong)高壓(ya)(ya)(ya)(ya)(ya)區流向低(di)壓(ya)(ya)(ya)(ya)(ya)區，經(jing)(jing)過(guo)毛細管放射到(dao)蒸(zheng)發(fa)(fa)(fa)器中，壓(ya)(ya)(ya)(ya)(ya)力驟(zou)降，液(ye)態(tai)制(zhi)冷(leng)(leng)(leng)劑立刻變成氣(qi)態(tai)，經(jing)(jing)過(guo)散熱(re)(re)(re)片(pian)吸收空(kong)氣(qi)中大量的(de)(de)熱(re)(re)(re)量。這樣(yang)(yang)循(xun)環應用(yong)就完成了制(zhi)冷(leng)(leng)(leng)系統。壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機通過(guo)節(jie)流裝置(zhi)節(jie)流之后，通入到(dao)蒸(zheng)發(fa)(fa)(fa)器中，將(jiang)所需要冷(leng)(leng)(leng)卻的(de)(de)媒介冷(leng)(leng)(leng)卻換(huan)熱(re)(re)(re)。例如將(jiang)蒸(zheng)發(fa)(fa)(fa)器連(lian)接到(dao)樓(lou)里的(de)(de)各(ge)個房(fang)間(jian)，蒸(zheng)發(fa)(fa)(fa)器內的(de)(de)蛇行(xing)管將(jiang)同空(kong)氣(qi)進行(xing)換(huan)熱(re)(re)(re)，再(zai)通過(guo)鼓風將(jiang)冷(leng)(leng)(leng)氣(qi)吹(chui)向房(fang)間(jian)的(de)(de)空(kong)氣(qi)當中。而蒸(zheng)發(fa)(fa)(fa)器蛇行(xing)管內的(de)(de)冷(leng)(leng)(leng)凍劑換(huan)熱(re)(re)(re)后變成低(di)壓(ya)(ya)(ya)(ya)(ya)蒸(zheng)氣(qi)回(hui)(hui)到(dao)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機，再(zai)被(bei)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)，這樣(yang)(yang)循(xun)環利用(yong)就完成了制(zhi)冷(leng)(leng)(leng)系統。
