現今由於溫室效應的關係，地球溫度逐年上升，如何有效利用能源成為人人必須重視的議題，熱泵熱水系統是一種可以吸收大氣熱能，經過熱轉換後加熱家庭所需用水，最後排放出冷氣，如此環保與節能的裝置，是未來的趨勢，然而，現今熱泵熱水器的控制面板，使用者在操作時，經常碰到二問題，第一，控制面板操控介面的設計不夠簡單明瞭，令使用者找不到想要操作的功能。第二，現有控制面板之造型多偏向於工業風格，若安裝於一般家庭之室內環境顯得突兀，因此，本研究針對此二問題進行探討，最終提出了二設計方針，分別為控制面板外觀造型設計原則與控制面板人機介面設計原則。

Earth temperature nowadays is gradually increasing due to the greenhouse effect, and how to efficiently use energy becomes a big issue that everyone should pay attention to. Therefore, heat pump system is a future-oriented trend. It can not only absorb heat energy in the air but also heat up water for domestic usage through thermal energy conversion and finally exhaust cold air. However, there are two common issues often discussed over heater control panels. First, the user interface design of control panel is neither simple nor distinct. People cannot locate and recognize the correct function button at the first sight while operating. Second, most modeling design for existing control panels are likely designed to industrial style. Attaching the industrial design control panel on the wall in normal domestic house is too abrupt. Therefore, this thesis comes up with two design guidelines by discussing above two problems. Two design guidelines are principles for control panel appearance design and principles for human interface design.
