南方农村许多农民使用的畜舍是破旧的小屋或草棚,均无保温措施,阴暗潮湿,气密性差。据了解,每年冬季,由于天气寒冷,经常发生猪、牛冻死现象。这不仅减少农民的收入,还影响养殖业的发展。因此,如何减少猪、牛的不正常死亡,对畜舍进行加温、保温是一个值得重视的问题。下面介绍简易太阳能畜舍的设计与施工。 1.尽可能增加太阳能集热量有两个途径:一是选择透光性好的材料,目前常用的有玻璃和塑料薄膜。普通玻璃的优点在于耐老化和透光率高,缺点是容易破裂,造价高。塑料薄膜的优点在于重量轻,不易破碎,价格便宜,缺点是表面易起毛,易老化。太阳能畜舍主要在冬季使用,时间不长,所以农村以选用薄膜为宜。二是扩大采光面积。为此,畜舍形式选用南窗和屋顶综合受益式,如
The barn used by many peasants in the southern rural areas is shabby cottages or shelters, with no insulation measures, dark and damp, and poor air tightness. It is understood that every winter, due to the cold weather, pigs often occur, frozen phenomenon. This not only reduces the income of farmers, but also affects the development of aquaculture. Therefore, how to reduce the abnormal death of pigs and cattle, and to heat and heat the houses is a problem that deserves attention. The following describes the design and construction of a simple solar barn. 1. As much as possible to increase the solar collector heat in two ways: First, choose a good light-transmissive material, currently used in glass and plastic film. Ordinary glass has the advantage of aging and high transmittance, the disadvantage is easy to crack, high cost. Plastic film has the advantage of light weight, not easily broken, cheap, the disadvantage is that the surface is easy to fluff, easy to aging. Solar barn mainly used in winter, not long, so the choice of film in rural areas is appropriate. The second is to expand the lighting area. To this end, the form of barn use South Window and roof integrated benefit, such as
