dc.description.abstract | 全世界對於環境相關議題更加重視,在節約能源方面,空調節能為主要研究對象,因台灣夏季炎熱,空調需求大,造成用電量急遽上升,排放大量溫室氣體產生更多的環境問題。本研究以吸附式冰水機結合雙效熱泵之複合系統,探討在夏季晴朗白天、夏季夜晚,具有節能效益的運轉模式。為了降低對電能的依賴,本研究使用太陽熱能提供吸附式冰水機作為製冷用途;使用淺層溫能恆溫水提供吸附式冰水機與雙效熱泵作為散熱用途,以達到節能環保的目的。
在運轉模式分析結果顯示,吸附式冰水機儲能預冷與淺層溫能雙效熱泵(製冷模式)製冷之運轉模式中,在熱水溫度53~70°C時,結合系統電力COP增加效益在13.6%~76.8%之間;吸附式冰水機與雙效熱泵(雙效模式)並聯製冷之運轉模式中,吸附式冰水機與雙效熱泵製冷時間占比為33%與67%時,能使系統製冷能力增加5%;吸附式冰水機與雙效熱泵(製冷模式)級聯製冷之運轉模式中,熱水溫度由63°C提升至77°C時,系統電力COP增加比例為28.9%。 | zh_TW |
dc.description.abstract | Environmental issues are valued by many countries. In terms of energy conservation, air conditioning energy-saving is the main research object. Taiwan is hot in summer. The demand for air conditioners is large, resulting in a sharp rise in electricity consumption and emit a lot of greenhouse gases. It will create more environmental problems. In this study, an adsorption chillers system combined with a dual-effect heat pump composite system is used to discuss the operation mode with energy-saving benefits in summer sunny day and summer night. In order to reduce the dependence on electrical energy, this study uses solar thermal energy to drive the adsorption chillers system for refrigeration purposes; Use shallow geothermal energy to provide adsorption chillers system and dual-effect heat pump for heat dissipation. This will achieve the purpose of energy saving and environmental protection.
Operation strategy analysis results are as follows. The adsorption chillers system pre-cooling and the shallow geothermal energy dual-effect heat pump (refrigeration mode) refrigeration system. According to the hot water temperature, an increase in the electric COP of the system ranges from 13.6% to 76.8%; the adsorption chillers system and the dual-effect heat pump (dual effect mode) parallel refrigeration system. When the refrigeration time ratio of the adsorption chillers and the dual-effect heat pump is 33% and 67%, the cooling capacity of the system can be increased by 5%; the cascade refrigeration system of adsorption chillers system and dual-effect heat pump (refrigeration mode). When the hot water temperature increases from 63°C to 77°C, the electric COP of the system increases by 28.9%. | en |
