寒冷地区奶牛舍建筑形式对牛舍热环境舒适性的影响效果
Effect of building forms on the thermal comfort of dairy barns in cold regions
摘要
Abstract
In response to the current problems of insufficient thermal insulation and heat preservation in dairy barns in cold regions of China,this study used a combination of the thermal evaluation of the building and heat stress assessment of the cows.The thermal resistances of the enclosure structure of the open barn and the closed window barn in the cold region were measured.The summer thermal environment conditions in the barns were tested and analyzed.The temperature-humidity index(THI)and the skin temperature index for cows(STIC)were used to assess heat stress of the cows.The predictive calculations of theoretical values for the thermal environment in winter in a barn were carried out based on previous studies.The comfort effect of the thermal environment in dairy barns with different building forms in cold regions was studied.The results showed that the thermal resistance and roof thermal resistance of both open and enclosed windowed barns met the requirements,but the thermal resistance of the side walls was significantly lower than the minimum thermal resistance required for the region.In the summer,both types of barns provided a relatively comfortable thermal environment in the cold region.The heat stress was not a serious problem for cows in the barns.However,in the winter,the indoor temperature in both types of barns did not meet the requirements.This study concluded that the open barn could not provide the suitable thermal environment inside the barn in the cold regions of the country.This study recommends the use of a closed windowed barn,which should have a thermal resistance value 1.137 m2·K/W for the walls and ≥1.459 m2·K/W for the roof.关键词
