الوصف: 隨著社會文明的進步,空調系統的使用已經成為了生活中不可或缺的物品。一般我們現在使用的冷氣機,其相對濕度的設定大多低於50%,對照台灣的氣候,其年平均濕度皆在70%以上,冷氣的濕度設定偏低了些。同時,如果能夠將設定的相對濕度提高,則更可以節省過多能源的消耗。透過本研究希望能夠說明,空調系統的溫濕度設定應該符合使用者的生理特性,同時,也希望說明擺放熱帶植物在室內做為減少自身水分散失是否真的有效果。 本研究使用黃金葛及幸運竹作為觀察對象,將其置入恆溫恆濕機內,藉由調整溫度、濕度的設定值,觀察植物失水量的多寡。而除了溫濕度的影響以外,葉片面積的大小也是影響水分散失多寡的重要因素。此外,還將比較不同植物間的失水差異。 實驗結果顯示,溫度越高、或是濕度越高的情況下,越有利於黃金葛與幸運竹的水分散失;葉片面積越大則散失量越高。但是在過於低溫的環境下,植物會發生凍傷的現象,影響水分散失的量。此外,低溫、低濕度的環境並不利於本實驗中的植物的蒸散作用的進行,因此擺放熱帶植物並無法有效的減少自身水分流失。當人們若是在長期待在冷氣房中,應該增加衣著覆蓋率,以減少直接暴露在外的皮膚表面積,進而減少皮膚水分的流失。因此,每個地區的人都有其適合的溫度濕度範圍,就如同黃金葛與幸運竹比較適合高溫高濕度的環境,而台灣地區人們適合的濕度範圍在50%~70%之間。而在相對濕度越高的環境,其能源消耗的量也越小。 ; With the progress of social civilization, the air conditioning systems have become essential items in life. Generally, the relative humidity setting of air-conditioners we using mostly control less than 50%. In the contrast, the average relative humidity of Taiwan is more than 70% throughout the year. So, the relative humidity setting of air-conditioners is lower than the demand which people living in Taiwan need. If we could increase the relative humidity setting of air-conditioners, then we could save much energy from waste. The objective of this study is to provide experimental data to explain the regulation of air-conditioners should be designed case by case, so that it can meet the user’s thermal comfort. Put the Epipremnum aureum and Dracaena sanderiana into a machine that could control temperature and humidity inside the chamber. By changing the temperature and humidity, we could investigate the amount of water loss of plants. Moreover, the size of leaf area is an important factor toward the amount of water loss. Finally, we will compare the amount difference of water loss between the two plants. The experimental results show that the amount of water loss of the two plants is proportional to temperature、humidity and the leaf area. When the plants are in the too cold condition, frostbite will occur, and affecting the amount of water loss. If people live in air-conditioned room for a long time, we should increase the rate ...
