摘要
基于当前能源利用现状,考虑到太阳能和燃气的有机结合,提出了复合太阳能的燃气机热泵系统,并建立了复合太阳能的燃气机热泵系统热力学模型。通过对系统中各组成设备的有用能分析,得出结论:随着出水温度的升高,冷凝器、蒸发器的有用能提高,压缩机的有用能降低,发动机和余热换热器的有用能变化不。压缩机随着转速的变化,其有用能损失变大,冷凝器和蒸发器的有用能损失也表现出相似的规律,其他的部件有用能损失几乎不变。虽然燃气热泵有用能量损失变化规律与是否复合太阳能并无过多直接关联,但在复合太阳能后,使燃气发动机配置功率降低,燃气量相应减少,除太阳能集热板之外的各部件有用能量损失值均降低,于此对于降低系统总能量的消耗具有重大意义。
Based on the current energy utilization status,taking into account the organic combination of solar energy and gas,the gas engine heat pump system with solar energy was proposed and thermodynamic model was established. Exergy for the components of the system was researched,and the conclusion was drawn. With the water temperature increasing,the exergy of the condenser and the evaporator increasing,the exergy of the compressor reduced,but the exergy of the engine and heat exchanger have little change hardly. With the change of engine speeding,the exergy loss of compressor becomes larger,and the exergy loss of condenser and evaporator also showed a similarity law,but other parts of exergy loss almost unchanged. There is little difference in the variation law of useful energy loss of gas engine heat pump with or without composite solar energy. However, after the solar energy is compound, the configuration power of the gas engine can be reduced, the gas quantity can be reduced, and the useful energy loss value of each component except the solar collector plate is reduced, which is of great significance for reducing the total energy consumption of the system.
