■用途
冬季隨著環境溫(wen)(wen)度(du)(du)(du)的降低,中(zhong)(zhong)央(yang)空調的制熱(re)效率也(ye)隨之降低,當環境溫(wen)(wen)度(du)(du)(du)與標準工況溫(wen)(wen)度(du)(du)(du)相差校大(標準工況室外溫(wen)(wen)度(du)(du)(du)為7℃)溫(wen)(wen)度(du)(du)(du)低于4℃時,中(zhong)(zhong)央(yang)空調將不能提供(gong)房間所需的溫(wen)(wen)度(du)(du)(du),為了補充不足的熱(re)量,就需要在原有供(gong)熱(re)設備的基礎上(shang)增加輔助加熱(re)器。
■優點
熱效率高、安(an)全性高、結構合理(li)、防腐性強,使(shi)用(yong)壽命長等(deng)。
