■用途
冬季隨著環(huan)境溫(wen)(wen)(wen)度(du)(du)的降(jiang)低(di),中央空(kong)調的制熱(re)效(xiao)率也隨之降(jiang)低(di),當(dang)環(huan)境溫(wen)(wen)(wen)度(du)(du)與標(biao)準工(gong)況(kuang)溫(wen)(wen)(wen)度(du)(du)相差(cha)校大(標(biao)準工(gong)況(kuang)室外溫(wen)(wen)(wen)度(du)(du)為7℃)溫(wen)(wen)(wen)度(du)(du)低(di)于4℃時,中央空(kong)調將不能(neng)提供房(fang)間(jian)所需(xu)的溫(wen)(wen)(wen)度(du)(du),為了(le)補充(chong)不足的熱(re)量,就(jiu)需(xu)要在原有供熱(re)設備的基礎(chu)上增加輔助加熱(re)器。
■優點
熱(re)效率高、安全(quan)性高、結(jie)構合(he)理、防腐性強,使(shi)用壽命長等。
