摘要

本研究旨在開發塔置型的環控裝置，透過控制器改變壓縮機的轉速，以控制蒸發器的溫度，達到箱內恆溫恆濕控制的目的。為了可以精確地控制箱內溫度，本研究先進行環控箱動態系統識別，然後進行控制系統設計分析。本研究實地開發一高性能環控箱原形機，以單晶片8051製成控制處理器，並對系統作完整的測試評估。結果顯示，可抵抗20w干擾，上升時在10±2分鐘內，間溫度誤差在±0.5℃以內，濕度比預設值還低。

The main purpose of the present research is to develop a tower-mounted high performance environmental control box. By modifying the rotational speed of the compressor, we can control evaporator's surface temperature to obtain constant temperature and humidity in the box. In order to accurately control operational temperature inside the box, the main purpose of the present research is to be environmental control box's dynamic system identification, then to be design and analysis of the control system. A prototype of high performance environmental control box using micro-controller 8051 was built and tested. The experimental results show that the temperature control error is less than 0.5℃ and the relative humidity can be controlled to a lower value them desired.
