【摘要】 我国奶牛舍围护结构保温设计缺乏系统的理论参考,易导致牛舍环境达不到设计标准、调控难度大等问题。本研究在充分调研国内外寒冷地区奶牛舍保温设计的基础上,提出了我国北方寒区奶牛舍围护结构以冬季低限热阻为主要参数的保温设计方法,并通过案例验算了在满足冬季最小通风设计条件下的牛舍保温性能。更多还原

【Abstract】 Due to a lack of the method in insulation design for the envelopes of dairy barns located in cold climate in northern China, thermal environment inside the barns usually could not reach the expected settings, making difficulties in controlling. Based on the practices in other countries with advanced animal production systems, a method of envelope insulation design for the dairy barns in northern China was investigated by considering the minimum thermal resistance requirement. Thermal balance of a dairy barn with a minimum air exchange rate for winter was theoretically calculated through heat gain and loss estimation to check the applicability of the method.更多还原
