居家熱舒適的節能可行性研究

Abstract

台灣屬海島型氣候，高溫高濕，使得居家的室內環境經常受到嚴重的濕氣影響，降低環境的舒適性。各家庭為了降低居家環境的相對濕度，經常使用冷氣機除濕，大幅提升能源的消耗。國內相關研究單位收集的資料只針對冷氣環境下的舒適度與冷氣機的效能做分析，沒有針對居家環境的熱舒適以及使用家電設備的方法不同，進行節能的可行性分析。 本研究主要以如何維持居家環境的熱舒適，並且達到節能的目標作為研究基礎，以實驗模擬的方法研究除濕機的運作模式，以一個約六坪空間的研究室為實驗基地，收集每天的室內溫度與相對濕度，比較室外的溫度與相對濕度；建立一個分析溫度、相對濕度與除濕機消耗功率的模型，有助於估計每天居家的能源使用量，故此，本研究的目標在於透過一種設備的實驗數據的收集與分析，探討居家熱舒適與節能的可行性。 本研究模擬出在穩定的溫度下，除濕機的能耗使用百分比與室內外溫度與室內外相對濕度的差異有顯著的關係。本研究發現若得知明日的室外溫度與相對濕度，則控制室內的溫度與相對濕度在不同設定，除濕機的能耗是可以估算的。

Taiwan’s climate is marine tropical with high temperature and relative humidity, thus, household environment is very uncomfortable for living, especially as a result of the high relative humidity. Most of the time, household runs air-conditioner to lower down temperature and relative humidity conventionally, however, they do not realize that this habit results a huge energy consumption. And many researches focused on the themal comfort in air-conditioning system or its saving efficiency. There is not research on the household thermal comfort and the feasibility of energy conservation with respect to using different electrical appliances. This thesis collected the data of indoor temperature, relative humidity, and outdoor temperature, relative humidity, with respect to the energy consumption of dehumidifier; in order to build a model between the states and energy use. With regression analysis, it is found that energy use of dehumidifier in steady stage is mainly affected by indoor temperature, outdoor temperature and relative humidity difference. With the model of energy consumption, it is feasible for household to estimate daily energy use.
