摘要

本省肉雞生產已逐漸採用密閉式環境控制，雞舍溫、溼度分佈會直接影響雞隻的生長，因此瞭解雞舍溫、溼度場分佈狀況是很重要的課題。本文以實驗量測長為75公尺，寬為22公尺與高為5公尺之密閉式雙層雞舍，詳細探討雞舍不同截面的溫、溼度分佈，結果顯示水牆降溫效率約為50%-60%，雞舍前、後段溫差約為3.5℃左右，而相對溼度則為愈往後段愈低，建議可在雞舍中段以後增加噴霧設施，提高降溫效果，使雞舍溫度分佈較均勻。若雞舍環控設施採用單點溫、溼度控制，則感測器裝置在雞舍中心位置較適當。

The closed type chicken house become popular for chicken production in Taiwan. The temperature and relative humidity distributions inside the chicken house will directly affect chicken growing. Therefore, understanding of the temperature and relative humidity distribution is an important topic for chicken growing. A double-floor, closed type chicken house (L75 x W22 x H5-m) was used to investigate the temperature and relative humidity distribution in this study. The results indicated the efficiency of ”pad-and-fan device” was around 50%-60%. The temperature difference between front and back section of the chicken house was about 3.5℃. The relative humidity increased gradually when the cool air flowed through the chicken house. A ”fog-and-fan device” was recommended to install at middle section of chicken house. In order to improve the efficiency of cooling system and the uniformity of temperature. To adopt a single-point temperature and relative humidity control system sensor should be installed at the center of the chicken house.
