臺灣博碩士論文加值系統

本研究使用兩臺對流式電暖器(2.2 kw)與兩臺暖風式電暖器(1.35和1.05 kw)，探討兩者配對組合之最佳暖房效率。
本研究之4D溫度收集系統，使用112支溫度感測器，可收集20、50和100 cm高度之2D平面溫度。該系統每10秒可顯示三個平面，3D溫度差(∆T)之等高線圖。每一實驗約120分鐘，產生720幀，最終以GIF影片格式存於雲端並依時間與高度逐批分析溫度差(∆T)等高線圖。
三組實驗結果顯示:
(1)即使，使用兩臺對流式電暖器，其高度20 cm之升溫區域為∆T=2℃ 370*200〖cm〗^2，非常有限。
(2)使用兩臺對流式電暖器加上一臺暖風式電暖器，可在高度20和50cm都達到∆T=3℃ 590*420〖cm〗^2之升溫區域。
(3)使用一臺對流式電暖器加上兩臺暖風式電暖器，結果可得在高度20cm之升溫區域達到∆T=4℃ 460*420〖cm〗^2、∆????=5℃ 150*280〖cm〗^2；高度50cm之升溫區域到達∆T=5℃ 400*320〖cm〗^2。本研究顯示，暖風式電熱器之熱氣流，可產生強制性熱對流，打破溫度分層之限制，擴大對流式電暖器之暖房效果。

The study investigates the optimal house-warming efficiency by combinations of two convection electric heaters of 2.2 kW and two fan heater of around 1.2 and 1.05 kW.
A 4D temperature collection system of 112 temperature sensors was used to collect temperature data at heights of 20 cm、50 cm and 100 cm. The system generates, every 10 seconds, three 3D-contour plots of temperature (∆T) for the three surface of different heights. An experiment usually last 120 mins and three series of 720 plots were saved for further analysis. The comparison of 3D-contour plots of ∆T with time and height as variables allows identification of effective heating regions so as the efficiency. The results of three group suggest: (1) the house-warming efficiency is very limited by using two convection heaters of 2.2 kw，and the regions of ∆T=2℃ is 370*200〖cm〗^2，at a height of 20 cm. (2) the house-warming efficiency is highly improved by adding an fan heater with a total power of 5. 75kw and the region of ∆T=3℃ are 590*420〖cm〗^2 at heights of 20 and 50 cm. (3) the house-warming efficiency were achieved by using of a convection heater and two fan heaters and the regions of ∆T=4℃, =5℃ were 460*420〖cm〗^2, and 150*280〖cm〗^2, respectively, at a height of 20 cm; the warm region of ∆T=5℃, was 400*320〖cm〗^2. At a height of 50 cm.
