■用途
冬季隨著環境溫(wen)(wen)(wen)度(du)的(de)降低,中(zhong)央(yang)空(kong)調的(de)制熱(re)效率也隨之降低,當環境溫(wen)(wen)(wen)度(du)與標(biao)準工(gong)(gong)況溫(wen)(wen)(wen)度(du)相差校大(標(biao)準工(gong)(gong)況室外(wai)溫(wen)(wen)(wen)度(du)為7℃)溫(wen)(wen)(wen)度(du)低于4℃時,中(zhong)央(yang)空(kong)調將(jiang)不(bu)能提供(gong)房間所需(xu)的(de)溫(wen)(wen)(wen)度(du),為了補(bu)充不(bu)足的(de)熱(re)量,就(jiu)需(xu)要(yao)在原有供(gong)熱(re)設(she)備的(de)基礎上增加輔助(zhu)加熱(re)器。
■優點
熱效率(lv)高、安全(quan)性高、結構合理、防腐(fu)性強,使用(yong)壽(shou)命長等(deng)。
