標準差與場協同理論於植物工場應用之研究

在現今大樓林立的時代直接的影響傳統農業的發展，可耕種的土地面積越來越少的情況，使得傳統農業遭受壓縮。而人類不斷在工業以及科技的開發下，造成了氣候異常和環境污染日益嚴重，在這樣的情況下不斷有溫室農場、垂直農場、植物工廠等智能型農場的產生。而本研究以模擬方式分析LED光源之植物工廠種植之紊流型進風口位置速度u、v、w、大小、進出風口溫度、LED燈條溫度及位置、冷卻鰭管降溫系統、熱負載等參數為模擬之變因，並且利用標準差公式計算溫度平均差異，分析出較佳的適溫，再利用場協同理論於溫室空間內入風口位置最佳化分析，並以COMSOL軟體進行分析場協同角的特性。本研究發現，場協同角越低表示速度場與溫度梯度場越平行對溫室空間所產生之降溫效果越好，也就是說場協同理論可以用來評估溫室空間出風位置並提供往後溫室建造、大樓內植物工廠之開發的一種指標最佳化設計對於空間流場及熱舒適性之差異影響。利用COMSOL軟體模擬速度場及溫度場，並以農作物適合溫度指標探討進、出風口對其速度場影響。模擬結果顯示使用不同入風口之後，對於溫室內空間舒適性可明顯的改善，其速度場變得較穩定，壓力較均勻。並依模擬結果在利用場協同理論可知速度場的溫差與流動速度協同越好，也就是角度越小使得找出入風口的最佳位置。

In today's building compact direct impacts the development of traditional agriculture. arable land area is less and the traditional agriculture suffered compression. Humans use modern development in industry and technology, to overcome bad climate and increasingly serious environmental pollution. Therefore, there have been a greenhouse farms, vertical farms, factories, and other intelligent plant farm. In this study, simulation and analysis of LED light factory-type plants are grown form different positions of the inlet velocity u, v, w, and its size, inlet and outlet temperature, LED light strip temperature and LED color located with cooling fin tube cooling system, heat load and other parameters to simulate the plant growing pattern. By field synergy theory and standard deviation, we can calculated the average temperature difference, optimum temperature, into and outlet position optimization analysis in the greenhouse space. COMSOL software are used for analysis in this case. The study found that the lower the field synergy angle, velocity and temperature gradient generated more parallel to the cooling effect of greenhouse space as possible. The field synergy theory can be used to assess the position of the wind greenhouse space and provide future greenhouse construction, an indicator of optimal design of the building plant factory developed flow field for thermal comfort and the impact of growing pattern.Use COMSOL software to simulate speed and temperature fields, and crops suitable growing pattern. Simulation results show that different air inlets of greenhouse space can be significantly improved the plant growing pattern, the velocity field becomes more stable, the pressure is uniform. And according to the simulation results by field synergy theory and standard deviation shows the temperature difference between the flow velocity and temperature gradient field of collaborative as possible, that is, the smaller the synergy angle so that the best place to find out from into and outlet parameters.
