采暖系統(tǒng)是依據(jù)統(tǒng)計的比較低室外溫度下所需的比較大熱負(fù)荷設(shè)計計算的。但溫控閥這種設(shè)計溫度*在嚴(yán)寒季出現(xiàn)幾天，這就意味著在整個采暖季中*這幾天采暖系統(tǒng)在滿負(fù)荷運行。通常來講，保障室溫所需要的熱負(fù)荷比設(shè)計值小的多，而且，熱負(fù)荷也在不斷的變化。整個供暖季每天的熱負(fù)荷也不同。溫控閥可以自動地按預(yù)定的要求保持準(zhǔn)確的室溫，而不受氣候條件的影響。在每個房間內(nèi)安裝一個溫控閥，保障能夠充分利用陽光、照明設(shè)施、機械和人體所散發(fā)的“**”熱能，以達(dá)到節(jié)省能源的效果。
