| 内容記述 | Heat-pump systems utilizing renewable resources can significantly enhance the energy efficiency of building air conditioning. This study focuses on a system that uses reservoir water as a renewable resource and develops a macroscopic numerical model to simulate heat sink temperatures, which critically influence the energy efficiency of heat pumps. Experiments were conducted to gather essential data for constructing this model. Heat was released, simulating the exhaust heat from a heat pump, from the bottom of an experimental tank filled with water. Initially, the water was thermally stratified, with the lower half at 15 °C and the upper half at 25 °C, mimicking summer conditions. The experimental results indicated that the heat release caused temperature increases exclusively in the lower layer, elevating the boundary between the layers by 0.2–0.4 m over 5 h. Consequently, we developed a heat sink temperature model by simulating the plume and entrainment of ambient water to replicate this phenomenon. The model accurately represented the increase in the boundary height across different scenarios, demonstrating a high level of agreement between the simulated heat sink temperature and the experimental values, with a deviation of <0.8 K. | |||||||||||||
