■用途
冬(dong)季隨(sui)著環境溫(wen)(wen)度(du)(du)的降低,中(zhong)(zhong)央(yang)空(kong)調(diao)的制(zhi)熱效率也隨(sui)之(zhi)降低,當環境溫(wen)(wen)度(du)(du)與(yu)標(biao)準(zhun)工況(kuang)溫(wen)(wen)度(du)(du)相差(cha)校(xiao)大(標(biao)準(zhun)工況(kuang)室(shi)外(wai)溫(wen)(wen)度(du)(du)為7℃)溫(wen)(wen)度(du)(du)低于4℃時,中(zhong)(zhong)央(yang)空(kong)調(diao)將不能(neng)提供(gong)房間所需(xu)的溫(wen)(wen)度(du)(du),為了補充不足的熱量,就需(xu)要在原(yuan)有供(gong)熱設備的基礎(chu)上增加輔助加熱器。
■優點
熱效率高、安(an)全性高、結構合理、防腐性強(qiang),使(shi)用壽命長等(deng)。
