摘要
介绍了太阳能-地下坑槽季节性土壤蓄热热泵供热系统的组成、运行模式,建立了系统的数学模型,编制程序针对北京地区进行了全年动态模拟。地下坑槽内的土壤可以保持以年为周期的热平衡,系统的年平均性能系数为6.89。
The composition and operation mode of solar-assisted ground-source heat pump heating system with seasonal soil heat storage in underground pit are introduced. The mathematical model of the system is established, the calculation program is compiled, and the whole year dynamic simulation of the system in Beijing is performed. The soil in underground pit can maintain an annual heat equilibrium, and the annual average performance coefficient of the system is 6.89.
