style="font-size:14px;">便可以達(dá)到理想的換氣目的。當(dāng)決定了換氣方式時(shí)，應(yīng)該注意設(shè)計(jì)房間和鄰室產(chǎn)生的壓力差。為了防止被污染空氣的流入，要注意換氣方式和風(fēng)量平衡，也就是說為了避免污染度較高的房間里的氣體流入外界，送風(fēng)量應(yīng)小于排風(fēng)量，以保證房間負(fù)壓；當(dāng)要求潔凈的房間，周圍環(huán)境較差時(shí)，送風(fēng)量應(yīng)大于排風(fēng)量，以保證房間正壓。四、機(jī)械通風(fēng)的方式根據(jù)通風(fēng)動(dòng)力應(yīng)用方式的不同，機(jī)械通風(fēng)可分為三種。方式一：給氣和排氣均利用機(jī)械力量。此種方式對(duì)于房間的送風(fēng)量和排風(fēng)量都可以進(jìn)行很好的控制，從而可以保證室內(nèi)的風(fēng)量平衡或控制房間處于正壓或負(fù)壓狀態(tài)。全熱交換器即為此種方式。方式二：利用機(jī)械力量，自然排風(fēng)。此時(shí)室內(nèi)一般都出于正壓狀態(tài)。熱泵型全新風(fēng)機(jī)即為機(jī)械給氣，如要保證室內(nèi)的風(fēng)量平衡，在進(jìn)行全新風(fēng)設(shè)計(jì)時(shí)，一般都另外需要考慮設(shè)置排風(fēng)風(fēng)機(jī)。方式三：利用機(jī)械力量，自然給風(fēng)。此種方式一般應(yīng)用在衛(wèi)生間、病房等需要負(fù)壓狀態(tài)的場所。五、新風(fēng)處理的方法現(xiàn)今，由于人們對(duì)于室內(nèi)環(huán)境舒適度與健康性的要求越來越高，室內(nèi)不僅需要適宜的溫度和濕度，還必須有新鮮的空氣，所以新風(fēng)系統(tǒng)的設(shè)計(jì)也越來越多的被人們關(guān)注。新風(fēng)引入方式有自然通風(fēng)和機(jī)械通風(fēng)兩種。</span>
