多功能太阳能辅助空气源热泵系统研究

Multifunctional Solar Assisted Air Source Heat Pump System

研究设计了一种多功能太阳能辅助空气源热泵系统,可实现一机多用,根据用户的不同需求,可在多种模式下运行。该系统将太阳能热利用技术与热泵技术相结合,克服了太阳能的不稳定性,同时有望提高太阳能热利用效率及系统综合运行性能。通过对该系统在某宾馆建筑中的应用研究发现:该系统全年月平均太阳能利用系数可达61.8%,综合运行性能比传统空调及热水供应系统有所提高,尤其在制冷季;与传统组合系统相比,系统运行能耗明显降低,全年平均节能接近50%。

A novel multifunetionul solar assisted air source heat pump system is presented. The studied system can work in different operating modes depending on different requirement of customers. The combintion of solac thermal application with heat pump technology has great potential in improving the comprehensive operating performance. A case study employing the system in a hotel is analyzed. The investi- gation results show that the solar fraction of the system can overagely reach 61.8%. Compared with conventional system, the comprehensive perfortannee is obviously promoted, especially in cooling season. Energy consumption of the studied system is also significantly reduced and nearly 50% can be saved.
