摘要
从维护土壤热平衡、降低系统初投资、提高系统的运行效率、增强系统的可控性等角度出发,设计出一套地源热泵与空气源热泵相结合的双源热泵系统。在夏季不同工况条件下,对目标建筑物双源热泵系统进行模拟及实验分析,得到系统在不同冷负荷条件下的最优运行模式:即地源热泵机组与空气源热泵机组始终耦合运行,当室外空气的干球温度高于32.5℃时,应采用空气源热泵优先卸载容量的策略;当室外空气的干球温度低于32.5℃时,应采用地源热泵优先卸载容量的策略。
A dual-source heat pump system was designed in order to keep the thermal balance of soil as well as reduce the equipment investment and improve system efficiency. The performance of the dual-source heat pump system is simulated and analyzed in the experiment for getting the optimal operation mode in different loading conditions. If the dry-bulb temperature of outdoor air is more than 32.5℃, the air source heat pump has priority to adjust its loads; If the dry-bulb temperature of outdoor air is less than32.5℃, the ground-source heat pump has priority to adjust its loads.
