我們在使用空調時候可能會發現其只制冷不制熱，這是什么原因？和武漢格力空調代理商簡單了解。

使(shi)用(yong)(yong)不(bu)當(dang)：空(kong)(kong)氣(qi)過(guo)(guo)濾器(qi)積(ji)塵(chen)太多、內(nei)(nei)外機通(tong)風(feng)(feng)口被(bei)異物堵(du)塞。過(guo)(guo)濾網(wang)(wang)的作用(yong)(yong)是吸附空(kong)(kong)氣(qi)中的灰塵(chen)，如果積(ji)累(lei)的灰塵(chen)太多而不(bu)及時清(qing)(qing)洗(xi)(xi)會堵(du)住空(kong)(kong)氣(qi)流(liu)(liu)通(tong)，從(cong)而造(zao)成出(chu)風(feng)(feng)口的出(chu)風(feng)(feng)量減(jian)少，致使(shi)機內(nei)(nei)制(zhi)熱(re)量無法被(bei)流(liu)(liu)動空(kong)(kong)氣(qi)及時帶出(chu)來，造(zao)成制(zhi)熱(re)量不(bu)足，這(zhe)不(bu)是故障，屬于(yu)空(kong)(kong)調(diao)的保養問題，只(zhi)需定期取(qu)下空(kong)(kong)氣(qi)過(guo)(guo)濾網(wang)(wang)清(qing)(qing)洗(xi)(xi)，就(jiu)可(ke)恢復(fu)正常(chang)，一(yi)般每半月(yue)清(qing)(qing)洗(xi)(xi)一(yi)次過(guo)(guo)濾網(wang)(wang)比(bi)較(jiao)適宜(清(qing)(qing)洗(xi)(xi)時注意勿用(yong)(yong)40℃以(yi)上的熱(re)水清(qing)(qing)洗(xi)(xi)，不(bu)得用(yong)(yong)洗(xi)(xi)衣粉、洗(xi)(xi)潔精、汽(qi)油、香蕉水等清(qing)(qing)洗(xi)(xi)，以(yi)免濾網(wang)(wang)變形，也不(bu)可(ke)用(yong)(yong)明火(huo)烘干(gan));蒸發器(qi)、冷凝(ning)器(qi)塵(chen)垢太厚，會降(jiang)低(di)換(huan)熱(re)效果，導致制(zhi)熱(re)能力下降(jiang)，耗(hao)電量增加;制(zhi)熱(re)溫度設定過(guo)(guo)低(di);空(kong)(kong)調(diao)房間門縫(feng)、墻洞未堵(du)死，或是開窗(chuang)開門頻(pin)繁，造(zao)成室(shi)內(nei)(nei)熱(re)量流(liu)(liu)失。

四(si)(si)通(tong)(tong)(tong)閥(fa)串(chuan)(chuan)氣：熱(re)(re)泵型空調通(tong)(tong)(tong)過四(si)(si)通(tong)(tong)(tong)閥(fa)來切換(huan)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)和制(zhi)(zhi)(zhi)熱(re)(re)狀態(tai)。在(zai)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)時(shi)，室外熱(re)(re)交(jiao)(jiao)換(huan)器(qi)作(zuo)冷(leng)(leng)(leng)凝(ning)器(qi)用，室內(nei)熱(re)(re)交(jiao)(jiao)換(huan)器(qi)當蒸發器(qi)吸收(shou)熱(re)(re)量;而制(zhi)(zhi)(zhi)熱(re)(re)時(shi)，室外熱(re)(re)交(jiao)(jiao)換(huan)器(qi)作(zuo)蒸發器(qi)，室內(nei)熱(re)(re)交(jiao)(jiao)換(huan)器(qi)當冷(leng)(leng)(leng)凝(ning)器(qi)釋放熱(re)(re)量。若四(si)(si)通(tong)(tong)(tong)閥(fa)串(chuan)(chuan)氣，則有(you)部分(fen)本(ben)應(ying)參(can)與熱(re)(re)交(jiao)(jiao)換(huan)的(de)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑在(zai)四(si)(si)通(tong)(tong)(tong)閥(fa)處直接由(you)壓縮機出氣管(guan)返回到回氣管(guan)，導致參(can)與熱(re)(re)交(jiao)(jiao)換(huan)的(de)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑減少(shao)，熱(re)(re)交(jiao)(jiao)換(huan)效率(lv)下降，從而引起制(zhi)(zhi)(zhi)熱(re)(re)量不(bu)足。外在(zai)的(de)表(biao)現主(zhu)要(yao)是(shi)高、低壓壓力不(bu)穩定，摸(mo)管(guan)道(dao)(接四(si)(si)通(tong)(tong)(tong)閥(fa)的(de)兩根(gen)熱(re)(re)管(guan)與兩根(gen)冷(leng)(leng)(leng)管(guan))冷(leng)(leng)(leng)、熱(re)(re) 不(bu)均勻;也(ye)有(you)些故(gu)障(zhang)表(biao)現為類似制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑不(bu)足或制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)、制(zhi)(zhi)(zhi)熱(re)(re)都不(bu)足，但通(tong)(tong)(tong)過檢測，高壓側壓力正(zheng)常。

單向(xiang)(xiang)閥(fa)(又稱(cheng)止逆閥(fa))漏氣：熱(re)泵(beng)型空(kong)調的(de)(de)(de)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)循環系(xi)統如附圖所(suo)示，熱(re)泵(beng)式空(kong)調器因制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)、制(zhi)(zhi)(zhi)(zhi)熱(re)狀態差別懸殊，僅靠電磁換(huan)向(xiang)(xiang)閥(fa)來切(qie)換(huan)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑的(de)(de)(de)流(liu)向(xiang)(xiang)，往往不(bu)(bu)可靠，因此(ci)，單向(xiang)(xiang)閥(fa)常(chang)用(yong)于熱(re)泵(beng)型空(kong)調器中，用(yong)來安(an)全有(you)效(xiao)地切(qie)換(huan)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)劑的(de)(de)(de)流(liu)向(xiang)(xiang)。在(zai)制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)循環時，高、低(di)壓(ya)(ya)(ya)差較小，節流(liu)元(yuan)件為主(zhu)(zhu)毛細(xi)管(guan)，而輔(fu)助(zhu)(zhu)毛細(xi)管(guan)被單向(xiang)(xiang)閥(fa)短路(lu);在(zai)制(zhi)(zhi)(zhi)(zhi)熱(re)循環時，與(yu)輔(fu)助(zhu)(zhu)毛細(xi)管(guan)并聯的(de)(de)(de)單向(xiang)(xiang)閥(fa)不(bu)(bu)導(dao)通(tong)，節流(liu)元(yuan)件為主(zhu)(zhu)毛細(xi)管(guan)與(yu)輔(fu)助(zhu)(zhu)毛細(xi)管(guan)串聯，這樣可增加節流(liu)元(yuan)件的(de)(de)(de)阻力，即(ji)增大制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)系(xi)統的(de)(de)(de)高、低(di)壓(ya)(ya)(ya)差，降低(di)室外熱(re)交換(huan)器的(de)(de)(de)溫(wen)度，從外界(jie)獲取更多的(de)(de)(de)熱(re)量，以達到制(zhi)(zhi)(zhi)(zhi)熱(re)的(de)(de)(de)目(mu)的(de)(de)(de)。當單向(xiang)(xiang)閥(fa)漏氣時，制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)系(xi)統的(de)(de)(de)高、低(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)差下降，室外熱(re)交換(huan)器的(de)(de)(de)溫(wen)度上升，從外界(jie)獲取的(de)(de)(de)熱(re)量減少，導(dao)致制(zhi)(zhi)(zhi)(zhi)熱(re)量不(bu)(bu)足。當出(chu)現(xian)空(kong)調制(zhi)(zhi)(zhi)(zhi)冷(leng)(leng)(leng)正常(chang)、制(zhi)(zhi)(zhi)(zhi)熱(re)量不(bu)(bu)足故障時，通(tong)過檢測系(xi)統運行時的(de)(de)(de)壓(ya)(ya)(ya)力，會發現(xian)低(di)壓(ya)(ya)(ya)側壓(ya)(ya)(ya)力上升，高、低(di)壓(ya)(ya)(ya)壓(ya)(ya)(ya)差下降。
