■用途
冬季隨著(zhu)環境(jing)溫(wen)度(du)(du)的降(jiang)低(di),中(zhong)央空調的制熱效(xiao)率也隨之(zhi)降(jiang)低(di),當環境(jing)溫(wen)度(du)(du)與標準工(gong)(gong)況溫(wen)度(du)(du)相差校大(da)(標準工(gong)(gong)況室外(wai)溫(wen)度(du)(du)為7℃)溫(wen)度(du)(du)低(di)于4℃時,中(zhong)央空調將(jiang)不能提供(gong)房(fang)間所需(xu)的溫(wen)度(du)(du),為了補充不足的熱量,就需(xu)要在原有供(gong)熱設備的基礎上增(zeng)加輔助加熱器。
■優點
熱(re)效率高、安全性高、結構合(he)理、防腐性強,使(shi)用壽命長等。
