內置多組浮動盤管，獨一無二的”寶塔型”結構,動態傳熱，換熱效率極高，相同容積的該產品的換熱量分別相當于傳統容積式換熱器的6～9倍。 容積式換熱器價格其中半容積式的”寶塔型”結構特點，使得貯水部分貯有15～30分鐘的熱水量，被加熱的水頭損失≤0.25米，因此它在設置一般自動溫控閥的條件下，仍保持供水水壓、水溫平穩、安全、節水、用水舒適之特點。浮動盤管式換熱器采用什么中置型浮動盤管型容積式換熱器可以提高容積利用率。浮動盤管型換熱器的換熱盤管距容器底可以近到100mm左右。其冷水區就很小，諸暨優質容積式換熱器有效貯熱(re)(re)容積可(ke)達99%左右，大(da)大(da)提高了換熱(re)(re)器的(de)容積利用率。本產品在用水(shui)量極(ji)小或(huo)不可(ke)用水(shui)時可(ke)借助熱(re)(re)水(shui)管網上循(xun)環泵的(de)工作(zuo)，維持罐內(nei)水(shui)溫(wen)，使(shi)(shi)換熱(re)(re)部分換熱(re)(re)時總處于被加(jia)熱(re)(re)水(shui)流動狀(zhuang)態，使(shi)(shi)換熱(re)(re)充分、節能。無論使(shi)(shi)用頻(pin)繁與否，均保(bao)量恒溫(wen)供(gong)水(shui)。
