摘要

目前植物工廠採用水耕栽種與化肥施肥的方式，產生高濕度與環境汙染等問題，為了栽種低溫類型蔬菜，反而使用耗能的空調設備。本研究提出低耗能的室內栽種方法，選擇有機的土耕栽種降低環境汙染問題，以節能的負壓通風取代空調設備調節溫溼度，並利用運算流體力學模擬軟體(CFD)模擬通風形式，建構合適的蔬菜栽種環境。再以艙體實驗探討栽種對室內環境品質中的光環境、熱溼環境、空氣品質(二氧化碳)與音環境的影響，提出改善方法並設計出低耗能的室內栽種系統。
本研究實驗發現以相對側通風路徑的負壓通風型式，配合離心式多翼型葉片風扇，可以使艙體內的通風均勻且降低環境噪音。當抽風扇風速使用1.2m/s/h，可降低艙內溼度過高問題，高於室內濕度約7~10%的之間，栽種芥藍菜每株所消耗的電力約為0.86 kWh，以土耕使用有機肥的方式栽種，達到節能與健康自給自足的需求。

High humidity and environmental pollution are created due to hydroponic and fertilizing method. Aiming to plant for low temperature vegetables, but ironically air condition systems with high energy consumption were used. This research proposes a low energy consuming planting technique, choose organic soil tillaget to reduce environmental pollution, negative pressure ventilation replaced with air-conditioning equipment to adjust temperature and humidity for energy-saving. Along with the use of simulating software (CFD) to calculate the formation of the circulation. This is to produce a suitable vegetable growing environment. Again with chamber experiment the research probes the effect between visual comfort, thermal environment, indoor air quality (IAQ) and Aural environment. This is to improve the methodology and also design a low energy consuming growing system.
This research experiment has discovered that using two openlings-opposite walls, collaborating with the fan allows the circulation in the chamber to be balanced, also decreases the noise within the environment. When exhaust system is operating at the speed of 1.2 m/s/h can decrease the high humidity problem in the chamber. The humidity would only be 7 ~ 10 % higher than outdoor. Planting Kale would consume approximately 0.86 kWh of electricity. By using the Soil tillage method of organic fertilizers can achieve the goal of energy saving and healthy self providing demands.
