■用途
冬季隨著(zhu)環境溫(wen)(wen)(wen)度(du)(du)(du)(du)的降低,中央空調(diao)的制熱效率也隨之降低,當環境溫(wen)(wen)(wen)度(du)(du)(du)(du)與標準工(gong)況溫(wen)(wen)(wen)度(du)(du)(du)(du)相差校大(標準工(gong)況室(shi)外(wai)溫(wen)(wen)(wen)度(du)(du)(du)(du)為(wei)7℃)溫(wen)(wen)(wen)度(du)(du)(du)(du)低于4℃時,中央空調(diao)將不(bu)能提供(gong)房間(jian)所需(xu)的溫(wen)(wen)(wen)度(du)(du)(du)(du),為(wei)了補充(chong)不(bu)足的熱量,就需(xu)要在原有(you)供(gong)熱設備的基礎上增加(jia)輔助加(jia)熱器(qi)。
■優點
熱效(xiao)率(lv)高、安全性高、結構合(he)理、防腐性強(qiang),使用壽命長等(deng)。
