■用途
冬季隨著環境溫(wen)(wen)(wen)度(du)(du)(du)的(de)降低(di),中(zhong)央(yang)空(kong)(kong)調的(de)制熱效率也隨之(zhi)降低(di),當環境溫(wen)(wen)(wen)度(du)(du)(du)與標準(zhun)工況溫(wen)(wen)(wen)度(du)(du)(du)相差(cha)校大(標準(zhun)工況室外溫(wen)(wen)(wen)度(du)(du)(du)為(wei)7℃)溫(wen)(wen)(wen)度(du)(du)(du)低(di)于4℃時,中(zhong)央(yang)空(kong)(kong)調將不能提供(gong)房間所需(xu)的(de)溫(wen)(wen)(wen)度(du)(du)(du),為(wei)了補充不足的(de)熱量,就需(xu)要在原有供(gong)熱設備的(de)基(ji)礎(chu)上(shang)增加(jia)(jia)輔助(zhu)加(jia)(jia)熱器。
■優點
熱效率高、安全性高、結構合理、防腐性強,使用(yong)壽命(ming)長等。
