摘要:
采用EES(Engineering Equation Solver)软件建立了跨临界循环混合工质热力学模型,以中原地区典型城市—郑州的气象和水文条件模拟R744/R290自然混合工质热泵系统的性能,基于计算数据，对总当量变暖影响(TEWI)进行了估算.结果表明:在设计工况下,不带回热器跨临界R744/R290热泵热水装置的最优制热COP可达4.104.经计算,用于郑州地区的年平均制热COP为4.202.与其他常规能源热水器相比,R744/R290热泵热水装置CO。排放量平均可减少36.39% .论文还计算并探讨了回热器和压缩机等嫡效率对热泵系统性能的影响.综合分析,R744/R290热泵热水装置具有能效高且环保的优点.
Abstract:
The thermal model using EES (Engineering Equation Solver) is developed,and then the systemperformance of transcritical R744/R290 heat pump water heater is simulated with the meteorological andhydrological conditions in Zhengzhou,the typical city in central China. The total Equivalent Warming Impacts(TEWIs) are calculated with the simulation datum. The results show that the maximum heating system COP is4.104 under the design condition without consideration of internal heat exchanger. When R744/R290 heatpump water heater is on operation in cnetral China,the mean annual heating COP of 4.202 can be achieved.Compared with the hot water heater using other energy,the R744/R290 heat pump water heater is averagelydecreased by 36.39% in the CO,emissions. It is also cacalated and discussed how the internal heat exchangerand compressor isentropic efficiency influence the system performances respectively. Therefore,the R744/R290 based heat pump water heater is characterized by a higher energy efficiency and a very effective way forremarkably reducing CO,emissions.
