問：如何檢測地源熱泵(beng)(beng)是否節(jie)能？大家對怎(zen)么(me)檢測地源熱泵(beng)(beng)是否節(jie)能，和如何減少現(xian)在的地源熱泵(beng)(beng)系統(tong)，有什么(me)看(kan)法(fa)，總是感覺現(xian)在設計的地源熱泵(beng)(beng)系統(tong)的地脈(mo)管數(shu)量太多。

答：地源熱泵要想節能就需要冬夏換熱平衡，具體的意思是夏季將熱量排入地下，冬季再取出，這樣熱泵系統換熱效率高，易節能。如果不平衡，換熱效率會逐年遞減，出現越來越不節能。地源熱泵機組利用土壤或水體溫度冬季為12-22℃，溫度比環境空氣溫度高，熱泵循環的蒸發溫度提高，能效比也提高；土壤或水體溫度夏季為18-32℃，溫度比環境空氣溫度低，制冷系統冷凝溫度降低，使得冷卻效果好于風冷式和冷卻塔式，機組效率大大提高，可以節約30--40%的供熱制冷空調的運行費用，1KW的電能可(ke)以得到(dao)4KW以上(shang)的熱量或5KW以上(shang)冷量。

地源熱泵原理上是(shi)利(li)用(yong)(yong)地(di)(di)(di)(di)(di)下冬冷夏熱(re)來實(shi)現(xian)制冷供(gong)暖，到(dao)(dao)實(shi)際工程(cheng)中并不(bu)能(neng)(neng)做到(dao)(dao)百(bai)分百(bai)補償，尤(you)其寒冷地(di)(di)(di)(di)(di)區或熱(re)帶地(di)(di)(di)(di)(di)區，地(di)(di)(di)(di)(di)源熱(re)泵(beng)用(yong)(yong)的太多會造成地(di)(di)(di)(di)(di)下熱(re)平衡失(shi)衡。冬冷夏熱(re)地(di)(di)(di)(di)(di)區相(xiang)對好一(yi)些，但也要(yao)控制應用(yong)(yong)密度，不(bu)然換(huan)熱(re)效果也會逐年(nian)衰減。地(di)(di)(di)(di)(di)源熱(re)泵(beng)技術(shu)所利(li)用(yong)(yong)的是(shi)地(di)(di)(di)(di)(di)球表面地(di)(di)(di)(di)(di)熱(re)源作(zuo)(zuo)為能(neng)(neng)量(liang)轉(zhuan)換(huan)，從(cong)而能(neng)(neng)為居民供(gong)暖起到(dao)(dao)幫助作(zuo)(zuo)用(yong)(yong)。地(di)(di)(di)(di)(di)球表面地(di)(di)(di)(di)(di)熱(re)源包(bao)括的范圍(wei)廣泛(fan)，比如表面土壤、河流、湖(hu)泊中吸收太陽能(neng)(neng)、地(di)(di)(di)(di)(di)熱(re)能(neng)(neng)而蘊藏(zang)的低溫(wen)位熱(re)能(neng)(neng)都屬于。這些能(neng)(neng)源都是(shi)不(bu)受(shou)什么限(xian)制的，都是(shi)可以再生的。
