■用途
冬季隨著環境溫(wen)(wen)度(du)(du)的降(jiang)低(di),中(zhong)央(yang)空(kong)調的制熱(re)(re)效率(lv)也隨之降(jiang)低(di),當環境溫(wen)(wen)度(du)(du)與(yu)標準工(gong)況溫(wen)(wen)度(du)(du)相差校大(da)(標準工(gong)況室外溫(wen)(wen)度(du)(du)為7℃)溫(wen)(wen)度(du)(du)低(di)于4℃時(shi),中(zhong)央(yang)空(kong)調將不能(neng)提供(gong)房間所需(xu)的溫(wen)(wen)度(du)(du),為了(le)補充(chong)不足的熱(re)(re)量,就需(xu)要在原有(you)供(gong)熱(re)(re)設備的基(ji)礎上(shang)增(zeng)加(jia)輔助加(jia)熱(re)(re)器。
■優點
熱(re)效率高、安全性高、結構(gou)合(he)理、防腐(fu)性強,使用壽命長等。
