爲了改善傳統空調機與熱泵熱水器能量回收的困境，本文研究開發ー款新型複合式空調熱泵熱水器，結合傳統空調系統及熱泵熱水器系統的優勢，並有同時提供冷源及回收儲存熱能之優勢，且可更進一歩得到降低能源使用量之效果。系統設計與傳統R410A空調機與熱泵熱水器共用零組件，並依據CNS 14464及CNS 15466試験法，於認證實驗室（TAF 1807)驗證空調冷氣及直接加熱式熱泵熱水性能。並於固定能力7.0 kW之設定下，得到冷氣性能係數COPr 3.95及加熱性能係數COP 3.89之結果，更在複合式空調熱泵設定下，得到總體性能係數COP。5.72之效果。

In order to improve the problem of energy recovery seen in traditional air-conditioners and heat pump heaters, a new type of multi-function air-conditioner and heat pump heater was developed in this study. With the advantages of the traditional air-conditioning system and the heat pump heater system, as well as a cooling source and thermal energy recycle and storage, reduced energy usage was achieved. The system is designed with shared components of the traditional air-conditioner and heat pump heater.
Additionally, in accordance with the CNS14464 and CNS15466 test methods, the air-conditioner and directly heated heat pump performance were confirmed in the laboratory (TAF1807). At the fixed capacity setting of 7.0 kW, the coefficient of performance of COPr 3.95, and the coefficient of performance of COP 3.89 were obtained for the air-conditioner and heater respectively. Further, under the setting of the multifunction air-conditioner and heat pump, the overall coefficient of performance of COPo 5.72 was achieved.
