一、优越性(一)结构科学管理方便:防空洞窖利用岩山打成,与外界隔绝良好,窖内温湿度变幅小,冬暖夏凉,比较湿润。窖尾设一气囱,可使空气自动对流,利于通风、散热、排湿。一门、一洞、一囱,可使全窖条件基本一致,不致形成局部冷热悬殊。门上设茅扇,冬季用以保温,春夏用以隔热。实际考察证明,只要建窖合乎要求,管理措施得当,外界气温降至零下4℃时,窖内仍能保持10℃以上;外界气温升至35℃左右时,窖内仍保持18—19℃。茅扇有一定的透气性,气囱又始终不堵死,即使在严寒阶段,窖内仍能通气,保持空气新鲜。窖内打水沟数条,用以调节
First, the superiority (a) the structure of science and management of convenience: anti-air cave pit made use of rock, cut off from the outside world is good, cellar temperature and humidity amplitude is small, warm in winter and cool in summer, more humid. At the end of the pit a gas chimney, air convection can be conducive to ventilation, cooling, wetting. A door, a hole, a chimney, can make the basic conditions of the entire cellar, will not form a partial hot and cold disparity. Door fan, winter for insulation, spring and summer for insulation. The actual inspection shows that as long as the cellar requirements, management measures properly, the outside temperature dropped to minus 4 ℃, the cellar can still maintain above 10 ℃; outside temperature rose to 35 ℃, the cellar still maintain 18-19 ℃. Mao fan has a certain permeability, the air chimney has not blocked, even in the cold phase, the pit can still breathe, keep the air fresh. Filling a few ditches in the cellar, to adjust
