摘要
对双热源太阳池热泵技术的应用进行了模拟研究。运用有限差分的方法，太阳池模拟结果表明，所储存的能量相对比较稳定，可为变负荷载荷供热；太阳池热泵技术的应用模拟结果表明，太阳池作为地位热源时。热泵制热的性能系数在4．08～4．87。若冬季太阳池作为低位热源的提热量为20W／m^2，完全能够满足冬季供暖时的温度要求。研究结果为实际利用提供了计算方法和重要依据。
A double heat source sun pond heat pump technology was studied by simulation with finite difference methods. Solar pool simulation results show that the stored energy is relatively stable and can be provided to the load of change heat load;the system＇s cop was between 4.08 - 4.87 when the heat pump heat was used for solar pond as low heat source. When solar pool was extracted by 20W/m^2 in winter, the simulation result indicated that it can definitely satisfy the heating requirements. Research result has provided a computational method and an important basis for the applications.
