| 为了缓解冬季通风与保温的矛盾,结合散养模式设计附加阳光间型鸡舍,冬季利用太阳辐射清洁能源提高舍内环境温度,同时增加舍内的通风换气量,有效降低舍内空气的相对湿度和有害气体浓度。分别选取12月份打开公共墙上门洞和1月份整体密闭的方式,对鸡舍环境温湿度进行测试。结果表明:打开门洞方式下舍内的平均湿度比密闭方式下低8.5％;在晴天10:00—16:00鸡群外出时间段,阳光间内平均温度基本维持在15 ℃以上,完全符合鸡的适宜生产温度条件,避免了散养鸡冬季外出活动因低温气候条件带来的健康危害。 |

| Abstract: |
| To alleviate the contradiction of ventilation and heat insulation in winter,a henhouse with attached sunspace,which combined is fit for a free-range system,was developed in this research.This design could make use of solar energy to effectively improve the air temperature,increase ventilation rate and reduce relative humidity and harmful gases concentrations.The temperature and humidity of air in the henhouse were measured under two different conditions,measured with the public doors opening in December and measured with airtight condition in January.It shows that the inner average relative humidity of air measured under the first condition is 8.5％ lower than that under the second one;The average air temperature of the sunspace could be maintained at above 15 ℃ from 10:00 to 16:00 during the day, according to the test in sunny days of December and January.It is completely suitable for the temperature requirements of a henhouse and avoids from doing harm to the free-range hens due to outdoor activities in cold weather. |
