■用途
冬(dong)季(ji)隨著環境(jing)(jing)溫(wen)(wen)(wen)度(du)(du)的降低(di),中(zhong)央(yang)空(kong)調的制熱(re)(re)效率也(ye)隨之降低(di),當(dang)環境(jing)(jing)溫(wen)(wen)(wen)度(du)(du)與標(biao)準工(gong)況(kuang)溫(wen)(wen)(wen)度(du)(du)相差校大(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(zhong)央(yang)空(kong)調將(jiang)不能提供房間(jian)所(suo)需(xu)的溫(wen)(wen)(wen)度(du)(du),為了補(bu)充不足的熱(re)(re)量,就需(xu)要(yao)在原有供熱(re)(re)設備的基礎上增加輔助(zhu)加熱(re)(re)器。
■優點
熱效率高、安全性高、結構合(he)理(li)、防腐性強,使用(yong)壽命長等。
