摘要
提出了双热源热泵供热系统、太阳能与水源热泵串联供热系统、太阳能与水源热泵并联供热系统,并建立了 3 种联合供热系统的仿真模型.在不同太阳辐射强度和水源温度下,对 3 种系统的供热性能进行了模拟分析,并绘制了 3 种系统的最佳运行区间图.结果表明,当太阳辐射强度和水源温度较低时,双热源热泵系统有最佳供热性能;当太阳辐射强度和水源温度较高时,并联系统供热性能最好;当太阳辐射强度和水源温度在前两种系统最佳工作条件之间时,串联系统有最好的供热性能.
Abstract
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.
