■用途
冬季隨著環境溫(wen)(wen)(wen)(wen)度(du)(du)的降低(di),中(zhong)央(yang)空(kong)調的制熱效率也(ye)隨之降低(di),當環境溫(wen)(wen)(wen)(wen)度(du)(du)與標準工況(kuang)溫(wen)(wen)(wen)(wen)度(du)(du)相差(cha)校(xiao)大(標準工況(kuang)室外(wai)溫(wen)(wen)(wen)(wen)度(du)(du)為(wei)7℃)溫(wen)(wen)(wen)(wen)度(du)(du)低(di)于4℃時,中(zhong)央(yang)空(kong)調將不能(neng)提供房間所需的溫(wen)(wen)(wen)(wen)度(du)(du),為(wei)了補充(chong)不足的熱量,就需要在原有供熱設(she)備的基礎(chu)上增加(jia)輔助加(jia)熱器。
■優點
熱效率高、安全性(xing)高、結構(gou)合理、防腐性(xing)強(qiang),使用壽命長等。
