■用途
冬季隨著環境溫(wen)度(du)(du)的降(jiang)低,中(zhong)央空(kong)(kong)調(diao)的制熱(re)(re)效率也隨之(zhi)降(jiang)低,當環境溫(wen)度(du)(du)與標準工(gong)況溫(wen)度(du)(du)相差校大(da)(標準工(gong)況室(shi)外溫(wen)度(du)(du)為7℃)溫(wen)度(du)(du)低于4℃時,中(zhong)央空(kong)(kong)調(diao)將不能提供(gong)房間(jian)所需的溫(wen)度(du)(du),為了補(bu)充(chong)不足的熱(re)(re)量,就(jiu)需要(yao)在原有供(gong)熱(re)(re)設備的基礎上增(zeng)加輔(fu)助加熱(re)(re)器。
■優點
熱效率高、安全性(xing)高、結構合理、防腐性(xing)強(qiang),使(shi)用壽命(ming)長等。
