Realization of the Air Conditioning Controller of Constant Temperature at Fix Point through Power Line Carrier Technology

[[abstract]]地球環境溫度逐年升高，空調系統的需求也十分普及，然而空調系統的用電量卻是快速增加。根據統計，冷氣溫度設定每降攝氏 1 度，其消耗電力就會增加15%。為了有效率的控制空調用電量，勢將投入大量具專業能力之人力與龐大之資源來研究，才足以發揮出降低空調系統耗能之具體成效。因此，如何以更具效率、更易執行之方式進行節能技術研究，為現階段重要的節能課題。目前空調冷氣無法有效傳播冷氣至周圍角落，造成有些角落較冷或較熱之情況，往往造成電力浪費。為了改善此問題，本計畫將搭配電力線載波技術，研發多點溫度偵測之智慧型空調控制器，其特點為不需另外鋪設控制線路與更改空調設備之電路結構，即可達到定點溫度回饋及遠端溫度設定之目的。因此本計畫將利用我們自行開發完成之新款電力線載波模組來傳輸各點溫度至空調主機，透過此技術開發一套定點恆溫空調控制器。該控制器將可執行冷氣空調之溫度調升、調降與及監控空調耗能之情形。相較於一般空調控制器更為方便及有效率的節省電費。[[abstract]]Global environmental temperature has been gradually on the rise and the demands for air conditioning system are also quite common and prevalent. Nonetheless the power consumption for air conditioning system is also rapidly increasing. According to the statistics, for every 1℃ decrease at the air conditioning temperature setting, its power consumption would increase 15%. Hence, in order to efficiently control the power consumption for the air conditioner, it is inevitable to pour massive manpower with professional talents as well as huge research resources. Therefore, it is then possible to showcase the concrete performance in lowering the air conditioning system power consumption. Thus, as for how to proceed to energy saving technology through methodologies with more efficiency and easier to carry out, becomes the vital energy saving topics at the current stage. Currently, the cool air from the air conditioning unit cannot be effectively transmitted to all surrounding corners and this leads to certain spots becoming colder or hotter; most likely it causes more power consumption. Hence, in order to rectify this problem, this project will conduct research in the intelligent air conditioning controller of multi-points temperature detection in conjunction to applying the power line carrier technology. Its characteristic rests at the fact that there is no need to lay out the external control circuitry or adjust the air conditioning equipment’s structured circuitry; then, it can achieve the purpose of fixed point temperature feedback as well as remote end temperature setting. Therefore, this project will apply the new type power carrier module that we just finished developing, to transmit the temperature at each point to the air conditioner server; and through this technology, we also developed a set of air conditioning controller with constant temperature at the fixed point. This controller can execute the temperature adjustment to high, low level and conduct surveillance against the power consumption for the air conditioner. As opposed to off-the-shelf air conditioning controller, this is much more convenient as well as can effectively save the electric bill.[[note]]NSC100-2622-E327-008-CC
