摘　　要：为了研究相变材料在北方冬季牛舍中的应用效果,试验在张掖市选择两个相同的双列式牛舍,在一个牛舍中悬挂相变材料,为试验舍,另一个不做任何处理,为对照舍,两牛舍进行对照处理,测量两牛舍内的温度、相对湿度、风速以及光照强度,对其热环境差异进行对比分析。结果表明:悬挂相变材料的牛舍温度高、相对湿度低、温度变化幅度小,相变材料可以使牛舍温度提高0.61~1.72℃,相对湿度降低2.71%~5.63%。说明相变材料可以在白天将多余热量吸收储存并在夜间释放出来,改善了舍内温热环境。In order to study the application effect of Phase Change Materials in the northern winter beef cattle cowsheds,two same double-row cowshed in Zhangye City were selected for this test.Among them,the cowshed with Phase Change Materials was the test group and the other was the control group.The temperature,relative humidity,wind speed and light intensity in the two cowsheds were measured and their thermal environment differences were compared and analyzed.The results showed that the temperature was high,the relative humidity was low,and the temperature change was small in the cowshed with Phase Change Materials.The Phase Change Materials can increase the temperature of cowshed by 0.61-1.72℃,and can reduce the relative humidity by 2.71%-5.63%.These results sindicated that the Phase Change Material can absorb excess heat during the day and release it at night,thus improved the temperature and thermal environment in the cowsheds.
