基于氟利昂制冷剂的ODP(臭氧层破坏势)和GWP(温室效应)问题,运用热力学方法,对CO2跨临界双级压缩带回热器循环TSCV+TGC+IHX与不带回热器循环TSCV+TGC建立了数学模型,并基于Visual Basic程序基础,开发了两种双级循环性能分析平台。结果表明,相同对比条件下,循环TSCV+TGC+IHX平均性能比循环TSCV+TGC高5%～10%,最优中间压力比循环TSCV+TGC低约5%～15%。本研究为高效、节能的CO2跨临界循环热泵热水器产品的开发提供了基础资料。
Based on the ODP (Ozone Destructive Potential) and GWP (Greenhouse Effect) problems of Freon refrigerants, the thermodynamic method was used to simulate the transcritical two-stage compression band regenerator TSCV + TGC + IHX and TSCV + TGC without regenerator The mathematical model is established, and based on the program of Visual Basic, two kinds of two-stage cycle performance analysis platform are developed. The results showed that the average performance of cyclic TSCV + TGC + IHX was 5% ~ 10% higher than that of cyclic TSCV + TGC and the optimal intermediate pressure was about 5% ~ 15% lower than that of TSCV + TGC under the same conditions. This study provides the basic information for the development of efficient and energy-saving CO2 transcritical cycle heat pump water heater.
