碩士 === 國立勤益科技大學 === 冷凍空調系 === 102 === This study uses theoretical calculations and experimental verification to develop a high-efficiency shower system with saving energy and water. This directly heating heat pump water heater （directly heating HPWH） uses new environmentally friendly refrigerant R410A and a thin plate type of heat exchanger integrated into a building. Waste shower water flows into the heat exchanger to recycle waste heat and the waste water, after simply filtered, then flows into a waste water storage tank. The system can achieve purposes of saving energy and water. After modifying the CNS15466 test standard for heat pump water heater with its outlet temperature from 55℃ to 40℃ and several improved methods in the study, the experimental results in the study show having 5.57 of COP for the directly heating HPWH, recycling 9.75kW of waste heat, and then having 9.32 of high saving energy performance coefficient for the developed showering system. Therefore, the heat pump in the system can reduce its volume by about 40 %, and can be easily integrated into showering space of a building.
