摘要:

针对目前建筑供暖/制冷能耗问题,提出了一种利用新型热回收式准二级压缩热泵的太阳能热泵供暖/制冷系统。通过建立系统仿真模型,分析了该系统在中国3种特征气候(重庆、太原、乌鲁木齐)下的运行情况。研究结果表明:该系统可利用新型热回收技术与太阳能光伏光热技术为建筑供暖、供冷,回收热量约占重庆、太原、乌鲁木齐房屋负荷的12%,光热供能占总负荷的30%,20%,15%;光伏利润占重庆、太原、乌鲁木齐房屋总运营成本的38%,26%,18%。可再生能源在新型热回收式准二级压缩热泵系统中起到了关键作用,可极大提升系统性能并减少碳排放。

Abstract:

To solve the problems of current energy consumption in building heating/cooling, a novel solar heat recovery quasi two-stage compression heat pump is proposed to be applied in heating/cooling systems. A system simulation model is established to analyze its operation performance under typical climatic conditions of three regions in China (Chongqing, Taiyuan and Urumqi). The research results show that the system can provide heat and cold energy for buildings with the new heat recovery technology, solar photovoltaic and solar thermal technologies. The recovered energy of Chongqing, Taiyuan and Urumqi takes about 12% of their total loads, and solar thermal energy of the three regions makes up 30%, 20% and 15% of their total loads, and PV profits accounted for 38%, 26% and 18% of their total operating costs, respectively. It can be seen that renewable energy plays a key role in new systems by greatly improving system performance and reducing carbon emissions.
