Preventing additional heat loss is crucial 阻止額外熱量的散失至關(guān)重要。
She says rescuers will first try to prevent additional heat loss by placing extra covering around a victim ' s chest , head and neck 她說救助者將放大量的覆蓋物在受害者的胸、頭和頸部來試著阻止額外的熱量損失。
She says rescuers will first try to prevent additional heat loss by placing extra covering around a victim ' s chest , head and neck 她說救援者將在第一時間用一件外套將受傷者的胸,頭和脖子包起來以免其余的熱量再散發(fā)出去。
She says rescuers will first try to prevent additional heat loss by placing extra covering around a victim ' s chest , head and neck 她表示救援者首先要通過在受傷者胸、頭、頸周圍放置額外的覆蓋物,盡力阻止更多的熱量散發(fā)掉。
She says rescuers will first try to prevent additional heat loss by placing extra covering around a victim ' s chest , head and neck 她說援救人員首先通過將額外的覆蓋物覆蓋在遇難者的胸部、頭部以及頸部來防止額外的熱量喪失。
She says rescuers will first try to prevent additional heat loss by placing extra covering around a victim ' s chest , head and neck . she says it is important to work fast to get people out of the cold and to medical help as soon as possible 她說救援者通過在受傷者的胸部、頭和脖子的四周添加額外的覆蓋來阻止更多的熱量散發(fā)并迅速將人移出寒冷和盡快進行醫(yī)療幫助是重要的。
Compared the heating load ( and energy consumption ) of a same room with floor heating or radiator heating under same operative temperature . revealed the energy consumption of floor heating room could reduce 5 % ~ 10 % to radiator heating , and the heating load could reduce 10 % ~ 15 % . the main season of energy efficiency is due to no apparent high temperature zone in floor heating room , which avoid additional heat loss in outside envelopes , rather than the lower of indoor air temperature 利用對連續(xù)供暖房間溫度場的研究結(jié)果,對分別采用上述兩種供暖方式的典型房間的熱負(fù)荷和能耗進行了全面分析后發(fā)現(xiàn):低溫地板輻射供暖房間熱負(fù)荷比散熱器供暖房間可降低10 15 ,能耗可降低5 10 ;低溫地板輻射供暖房間節(jié)能的主要原因并不是由于房間空氣溫度可以降低,而是消除了室內(nèi)空氣局部高溫區(qū),避免了由此產(chǎn)生的在外圍護上的附加傳熱量。
