瓦特是常用的在熱量物產的測量。空氣(濕氣)的質量
溫室內溫度上升之程度除受進入溫室之光線入射量影響之外,溫室的通風程度、地面上作物生長情形等都直接相關。當室溫一直上升,其對外之放熱(包括傳導、對流與輻射)也隨著加大,當放熱與陽光入射熱達到平衡,便達到升溫的極限。
  談到溫、濕度控制,離不開能量與質量守恆兩大定律;談到溫、濕度控制,也離不開空氣與水。含有水蒸氣的空氣稱之為濕空氣(moist air);有關濕空氣的各種關係在濕空氣熱力學(Psychrometrics )中有詳細的探討。本章之主題即在介紹濕空氣之各種熱力性質、其應用及相關之微電腦軟體。最後簡單介紹本省的溫、濕度氣象條件。
二、能量與質量守恆
  透過適當之軟、硬體來量測溫室內、外的環境參數值,並根據各參數之設定值來計算精確的各類驅動器之設定值,譬若:鍋爐或加熱器之設定溫度、風扇之開啟個數與轉數、窗戶開口之大小、噴霧裝置之噴嘴使用數量及流量等,就是所謂的溫、濕度控制。精確且無矛盾的控制可保證作物於適宜的環境中生長。
  溫、濕度控制系統的好壞取決於系統的設計,系統設計涉及諸多計算,一切計算則都由質量與能量守恆開始;此處之質量泛指水份、養料、氧氣、二氧化碳等。溫室環境內之質量守恆可以下式簡單說明
進入系統之質量=離開系統之質量+儲存於作物內
新增之生理質量 (BioMass)
  能量可透過太陽照射,熱輻射,熱傳導,熱對流,冷凝,或隨進入溫室之流體進入溫室或透過加熱器,熱交換器,輔助燈光等在溫室中產生。能量也藉由反射太陽光線,熱輻射,熱傳導,熱對流,蒸發,空調,熱交換器或隨離開溫室之流體離開溫室。儲存於系統之能量為正值則表示系統本身之能量增加,其對生物及環境之明顯效應為環境溫度及作物新陳代謝速率的增加。能量守恆為熱力學第一定律,其公式如下:
  進入系統之能量=離開系統之能量+儲存於系統之能量
六、結語
濕空氣熱力特性的基礎理論允許吾人在規劃環控策略時有理論之依據,可將錯誤發生減至最少。氣象資料允許吾人對溫室所在地的大氣狀況有一概括性的瞭解,更可讓吾人瞭解到溫、濕度控制的極限。濕空氣熱力特性計算軟體提供吾人一有用之工具以進行環控系統之設計與評估。

✔ 最佳答案
Watt is commonly used in thermal measurement products. Air (humidity) the quality of
Greenhouse addition to the degree of temperature rise into the greenhouse by the incident in light of the impact of greenhouse ventilation of the situation on the ground and so on crop growth are directly related. When the temperature has been rising, the heat of its foreign (including conduction, convection and radiation) with the increase, when the heat of the sun and heat balance of incident, they reached the limit warming.
Turning to temperature and humidity control, energy and quality can not be separated from the two major conservation law; talking about temperature and humidity control, can not be separated from air and water. Containing water vapor the air as moist air (moist air); wet air on the various relations in the humid air thermodynamics (Psychrometrics) are detailed in the study. The theme of this chapter is introduced in the humid air of various thermal nature, its application and related microcomputer software. Finally brief province's temperature and humidity weather conditions.
Second, energy conservation and quality
Through the appropriate software and hardware to the indoor temperature of, the environment outside the parameters, and in accordance with the parameters set to calculate the precise drivers of all types of settings, Piruo: boiler or heater temperature settings, fan of Open to the number and the number of openings the size of the windows, spray nozzle devices such as the use of volume and flow, is the so-called temperature and humidity control. Precision and no contradiction between the control can ensure that crops in the appropriate environment for the growth.

2008-09-12 16:23:00 補充:
Temperature and humidity control system is good or bad depends on the system design,

2008-09-12 16:23:59 補充:
systems design involves many, all in terms of quality and energy conservation are beginning here refers to the quality of water,

2008-09-12 16:25:43 補充:
nutrients, oxygen, carbon dioxide, and so on. The quality of greenhouse environment can be conserved under a simple note -
Access to the system of quality systems in the left = + stored in the quality of the crop

2008-09-12 16:26:01 補充:
Add the physical quality (BioMass)
Energy through solar radiation, thermal radiation, heat conduction, convection heat, condensation, or into the greenhouse with a fluid into the greenhouse or through the heater,

2008-09-12 16:26:21 補充:
heat exchangers, such as auxiliary lighting in the greenhouse produce. By reflecting solar energy is also light, heat radiation, heat conduction, convection heat, evaporation, air conditioning
