| 为了研究光伏光热−热泵系统供热水箱与蓄热水箱大小匹配的问题，利用TRNSYS软件建立了光伏光热−热泵系统的仿真模型。利用实测数据对仿真模型进行了验证，结果表明误差均在合理值范围内，认为构建的仿真模型具有准确性和可靠性。针对100，200，300 L这3种不同容量的供热水箱，分别选取了30，60，90 L/m2的蓄热水箱来匹配各容量的供热水箱。对系统仿真模型进行了全年运行性能模拟，并选用全年?损作为评价指标对系统进行评价，模拟结果表明，对于3种不同容量的供热水箱，蓄热水箱容量皆为60 L/m2时系统全年?损值最小，推荐匹配各容量供热水箱的蓄热水箱大小为60 L/m2。 |

| To study the problem of size matching of the heating tank and the thermal storage tank in the photovoltaic thermal-heat pump system, a simulation model of the photovoltaic and thermal-heat pump system was established by using TRNSYS software. The model was tested using the measured data, and the findings revealed that the errors were within reasonable bounds, indicating that the simulation model was accurate and dependable. Thermal storage tanks with the sizes of 30, 60, 90 L/m2 were selected to match the heating water tanks with different capacities of 100, 200, 300 L, respectively, and an annual operating performance simulation of the system model was conducted using the system model. To evaluate the system, the annual exergy loss was chosen as the evaluation index. Simulation results show that the annual exergy loss of the system is the smallest when the capacity of the storage tank is 60 L/m2 for all the three different capacities of the heating water tank. As a result, the thermal storage tank with a size of 60 L/m2 is advised to match each capacity of the heating water tank. |
