■用途
冬季隨(sui)(sui)著環境溫(wen)(wen)度(du)(du)的降低(di),中(zhong)央空調的制熱(re)效率也(ye)隨(sui)(sui)之降低(di),當環境溫(wen)(wen)度(du)(du)與標(biao)準工(gong)況(kuang)溫(wen)(wen)度(du)(du)相差校(xiao)大(標(biao)準工(gong)況(kuang)室外(wai)溫(wen)(wen)度(du)(du)為(wei)7℃)溫(wen)(wen)度(du)(du)低(di)于4℃時(shi),中(zhong)央空調將不(bu)(bu)能(neng)提供(gong)(gong)房(fang)間(jian)所(suo)需(xu)的溫(wen)(wen)度(du)(du),為(wei)了(le)補充(chong)不(bu)(bu)足的熱(re)量,就(jiu)需(xu)要(yao)在原有供(gong)(gong)熱(re)設備的基礎上增加(jia)輔(fu)助加(jia)熱(re)器(qi)。
■優點
熱效率高、安全性(xing)(xing)高、結構合(he)理(li)、防腐性(xing)(xing)強,使用壽(shou)命長等(deng)。
