問：地源熱泵壓縮機的作用和空調一樣嗎？

答：地(di)源(yuan)熱(re)(re)泵(beng)壓縮(suo)機(ji)的(de)(de)作(zuo)用(yong)(yong)(yong)(yong)和空(kong)調的(de)(de)作(zuo)用(yong)(yong)(yong)(yong)不一(yi)樣的(de)(de)。首先要(yao)說明一(yi)點，我(wo)(wo)們(men)用(yong)(yong)(yong)(yong)的(de)(de)地(di)源(yuan)熱(re)(re)泵(beng)的(de)(de)地(di)能(neng)(neng)(neng)是(shi)低(di)溫地(di)能(neng)(neng)(neng)，而不是(shi)用(yong)(yong)(yong)(yong)的(de)(de)地(di)下的(de)(de)高溫熱(re)(re)能(neng)(neng)(neng)。根據熱(re)(re)力學原理，能(neng)(neng)(neng)量不能(neng)(neng)(neng)自發的(de)(de)從(cong)低(di)溫向高溫傳遞(di)，就(jiu)(jiu)像水(shui)不能(neng)(neng)(neng)自發的(de)(de)從(cong)低(di)處(chu)往高處(chu)流(liu)一(yi)樣。要(yao)把(ba)低(di)處(chu)的(de)(de)水(shui)送(song)到高處(chu)，我(wo)(wo)們(men)就(jiu)(jiu)需要(yao)水(shui)泵(beng)，利用(yong)(yong)(yong)(yong)水(shui)泵(beng)把(ba)水(shui)從(cong)低(di)處(chu)送(song)到高處(chu)。類此(ci)(ci)，對于地(di)下的(de)(de)低(di)溫地(di)能(neng)(neng)(neng)，我(wo)(wo)們(men)就(jiu)(jiu)需要(yao)通(tong)過壓縮(suo)機(ji)來完成逆(ni)卡諾循環，把(ba)地(di)下的(de)(de)低(di)溫熱(re)(re)能(neng)(neng)(neng)提取以(yi)供我(wo)(wo)們(men)使用(yong)(yong)(yong)(yong)。地(di)源(yuan)熱(re)(re)泵(beng)的(de)(de)壓縮(suo)機(ji)就(jiu)(jiu)如同抽水(shui)的(de)(de)水(shui)泵(beng)。通(tong)過壓縮(suo)機(ji)，我(wo)(wo)們(men)可以(yi)利用(yong)(yong)(yong)(yong)少量的(de)(de)電能(neng)(neng)(neng)就(jiu)(jiu)可以(yi)得到很多地(di)熱(re)(re)能(neng)(neng)(neng)，因此(ci)(ci)就(jiu)(jiu)用(yong)(yong)(yong)(yong)了地(di)源(yuan)熱(re)(re)泵(beng)系統能(neng)(neng)(neng)效比（COP）這個名詞。

我們要搞清楚地源熱泵的工作原理，首先要懂得制冷系統的工作(zuo)原理。制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)統（壓(ya)(ya)(ya)縮(suo)式制(zhi)(zhi)冷(leng)(leng)(leng)）一(yi)般由(you)四部分(fen)組(zu)成(cheng)(cheng)：壓(ya)(ya)(ya)縮(suo)機、冷(leng)(leng)(leng)凝(ning)器、節(jie)流閥、蒸(zheng)發(fa)(fa)器。其工作(zuo)過程為：低溫(wen)低壓(ya)(ya)(ya)的液態制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)（例(li)如氟利昂），首先(xian)在蒸(zheng)發(fa)(fa)器里(li)(li)從低溫(wen)熱(re)源(yuan)(yuan)（例(li)如冷(leng)(leng)(leng)凍水(shui)）吸熱(re)并氣化。然后(hou)壓(ya)(ya)(ya)縮(suo)機抽取蒸(zheng)發(fa)(fa)器里(li)(li)氣化后(hou)的制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)氣體并壓(ya)(ya)(ya)縮(suo)到(dao)冷(leng)(leng)(leng)凝(ning)器內(nei)，此時制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)氣體變成(cheng)(cheng)高(gao)溫(wen)高(gao)壓(ya)(ya)(ya)氣體。該(gai)高(gao)溫(wen)高(gao)壓(ya)(ya)(ya)氣體在冷(leng)(leng)(leng)凝(ning)器內(nei)被高(gao)溫(wen)熱(re)源(yuan)(yuan)（例(li)如冷(leng)(leng)(leng)卻(que)水(shui)）冷(leng)(leng)(leng)卻(que)凝(ning)結成(cheng)(cheng)液體，變成(cheng)(cheng)高(gao)溫(wen)高(gao)壓(ya)(ya)(ya)液體制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)。再經(jing)節(jie)流閥截(jie)流成(cheng)(cheng)低溫(wen)低壓(ya)(ya)(ya)液態制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)。如此就完成(cheng)(cheng)一(yi)個制(zhi)(zhi)冷(leng)(leng)(leng)循環。
