容積式和半容積式的就差在:半容式的換熱管束帶筒體,而容積式的不帶.容積式熱交換器優點1、傳熱系數高 彈性管束管是用高導熱系數的紫銅制成高效傳熱元件，容積式熱交換器價格加上合理的換熱器內部結構，大大提高了換熱器的性能。、不易結垢 由于換熱管多采用紫銅，而且易形成湍流的流體對換熱管壁面有較強的沖刷作用，加上彈性管束本身有熱補償能力，通過熱脹冷縮有自潔作用，因此不易結垢。 3、無冷水區，容積利用率高 加熱罐底部的冷水，在用水量低于額定供水能力時，逐步將罐內冷水全部加熱，此時無冷水區，以維持熱水的最大儲備量。當用水量大于額定供水能力時，遼寧容積式熱交換器罐內儲存的熱(re)水(shui)和即時加熱(re)的熱(re)水(shui)同(tong)時向(xiang)外供(gong)以(yi)度(du)過用水(shui)高峰。當(dang)因(yin)事故或(huo)其(qi)他原因(yin)停供(gong)熱(re)媒(mei)時，能最大限度(du)地(di)供(gong)應所出貯存的熱(re)水(shui)。
