人工孵化場所理想空調環境之氣流模擬分析

傳統家禽產業在空氣環境衛生上，並不十分重視，容易忽略環境衛生之危害性而造成家畜禽受到病毒或細菌入侵，產生相互感染和造成病害，對台灣的家畜禽飼養工業造成相當大的危害及損失，因此可利用空調技術的應用，提供良好且適合的環境品質，尤其當受精蛋於孵化過程中，孵化環境將是影響孵化成功率之重要關鍵因素，在現代式之大型人工孵育室已有使用空調系統進行溫度調節，但對室內氣流、溫度、濕度及品質並沒有良好控制，因此本研究針對人工孵化場所孵化室環境進行氣流分佈之三維電腦模擬分析，採用商用氣流分析軟體FLOVENT來計算人工孵化室詳細流場，包括速度場、溫度場等，並以數值計算的方式獲得長時間環境之變化狀態及三維空間穩態數值變異量。經由研究設計之「人工孵化場所孵化室理想空調環境」案例模擬後的流場分佈情形，可以獲得人工孵化場所內部的氣流環境，因此本研究利用氣流模擬方法，探討出人工孵化室內循環最佳的供風風扇角度，對於研究之實例而言，原設計風扇供風角度為下吹30°，經模擬後可發現上吹45°為較佳的設計設定角度，其空間內部溫度分佈為最理想；再配合增設濕度控制系統，適宜的通風換氣、氣流過濾設施與紫外線殺菌燈，即可獲得最佳溫度、濕度及空氣品質的空調理想空氣優質環境。

Air quality/purification issues for the environment of traditional poultry industry were never been taken seriously. The environmental sanitation has been ignored in the past which allows virus or bacterium threatens the local poultry production and industries. It results by transmitted the diseases and infection to each other within the farms, therefore causes enormous of damages and lost profits to the business. The practical utilization of air conditioning technology and its application provides better air quality and air purification for varieties of environmental conditions, especially during fertilized egg and the hatching process. It definitely will show as an important factor that influences the success rate on hatches and overall processing environment. Recently, modernized artificial incubation and hatching facilities were using air conditioning system to regulate temperatures; although often overlooked when it comes to indoor airflow, temperature, humidity and its air quality. The research will focus and inducted a three-dimensional computer simulation analysis on airflow distribution for the environments of artificial hatching area. By using Flow Solution Software FLOVENT to calculate the statistics of air distribution including temperature and speed field tests …etc. From the statistics knowing that continuous environment changing conditions and varies of stable state in three-dimensional space. This significant study and airflow simulation 「The Ideal Air Conditioning Environment for Artificial Incubation Room」will be able to comprehend the airflow pattern in artificial incubation room. The purpose of this research is utilizing the airflow simulation, by adjusting the angle of the fan. Regarding to an ideal design of artificial incubation room, the optimal design is by tilted the fan to a 45 degrees angle for constant temperature and air distribution. Additionally, by install and combine humidity control with dehumidifier, ultraviolet light sterilizer, air filtration and suitable ventilation to achieve the ideal air conditioning environment.
