■用途
冬季隨著環(huan)境溫(wen)(wen)(wen)(wen)度(du)的降(jiang)低,中(zhong)央空調(diao)的制熱效率也隨之降(jiang)低,當環(huan)境溫(wen)(wen)(wen)(wen)度(du)與標(biao)準(zhun)(zhun)工況溫(wen)(wen)(wen)(wen)度(du)相差校(xiao)大(標(biao)準(zhun)(zhun)工況室(shi)外溫(wen)(wen)(wen)(wen)度(du)為7℃)溫(wen)(wen)(wen)(wen)度(du)低于4℃時,中(zhong)央空調(diao)將不(bu)能提供房間所需(xu)(xu)的溫(wen)(wen)(wen)(wen)度(du),為了補充不(bu)足的熱量,就需(xu)(xu)要在原有供熱設備的基礎上增加輔助加熱器。
■優點
熱效率(lv)高、安全性高、結(jie)構合理、防(fang)腐性強,使(shi)用壽(shou)命(ming)長等。
