本文基于太阳能光伏光热一体化系统,设计出应用太阳能光伏光热及空气源的双热源热泵机组。使热泵与太阳能光伏光热组件结合组成太阳能热泵系统,利用太阳能光伏光热组件( PV/T)内循环水及空气源的能量制取生活热水,同时降低太阳能光伏光热组件内循环水的温度,从而降低太阳能光伏板的温度。通过实验测得机组在水冷蒸发侧进水温度20℃,热水出水温度50℃的额定工况下,制冷量为2.855 kW,制热量为3.594 kW,COP为3.6。机组在水-水工况及水-风工况下运行的节能性研究结果表明,相对于单一空气源热泵,双热源热泵机组在满足家庭用生活热水需求的前提下,利用热泵技术回收太阳能光伏光热的热量制取生活热水节能性显著。

Based on the solar photovoltaic-thermal integrated system, we designed a dual-source, i. e. , solar photovoltaic-thermal and air source, heat pump unit. The unit becomes solar assisted heat pump system when combined with solar photovoltaic thermal unit, which produces domestic hot water by air source and circulating water in the solar photovoltaic solar-thermal components ( PV/T) and reduces circulating water temperature and solar photovoltaic panel temperature. We drew the conclusion by experiment that when the inflow water temperature is 20 ℃ on the evaporation side and the outflow hot water temperature is 50 ℃ under the rated conditions, the unit capacity is 2. 855 kW for refrigeration and 3. 594 kW for heating, and the COP is 3. 6. When the unit operates in the water-water condition and wa-ter-air condition, the experiment result shows the dual-source heat pump unit has remarkable energy-saving compared with single air source heat pump when the photovoltaic-thermal solar heat is used for domestic hot water.
