Simulation study on heating performance of combined system of solar collector and water source heat pump
The double heat source heat pump heating system,the solar and water source heat pump series heating system,the solar and water source heat pump parallel heating system are proposed,and the simulation models of three combined heating systems are established.Under different solar radiation intensity and water source temper-ature,the heating performance of the three systems was simulated and analyzed,and the optimal operating interval of the three systems was plotted.The results show that when the solar radiation intensity and water source temperature are low,the dual-heat source heat pump system has the best heating performance.When the solar radiation intensity and water source temperature are high,the shunt system has the best heating perform-ance;When the intensity of solar radiation and the temperature of the water source are be-tween the optimal working conditions of the first two systems,the tandem system has the best heating performance.
