摘要
基于贵阳市某高校图书馆的太阳能辅助地源热泵系统设计,首先介绍桩基螺旋盘管与水平地埋管相结合的地埋管换热器;然后利用De ST软件对该图书馆进行全年负荷计算,以此制定地源热泵-太阳能系统联合运行的热平衡方案,并介绍了热泵机组和太阳能集热器设备选型情况;最后,分析了地源热泵-太阳能系统相对于传统电制冷机组-燃气锅炉系统的节能效益和环保效益。
Based on the design of solar-assisted ground-source heat pump system in a university library in Guiyang,the pile spiral ground heat exchanger combined with horizontal ground heat exchanger is introduced firstly. Then the heat balance method of solar-assisted ground-source heat pump system is developed with the calculation of annual building load by De ST software. And the equipment type selection of heat pump unit and solar collector are introduced. Finally,the economic performances and environmental benefits of the solar-assisted ground-source heat pump and traditional electric refrigeration units plus gas-fired boilers are compared.
