摘要
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。
To address the ODP(Ozone Depletion Potential) and GWP(Global Warming Potential) problems arisen from freon refrigeration coolant,mathematical models were established for CO2 trans-critical dual-stage compression cycle with a recuperator(TSCV+TGC+IHX) and without a recuperator(TSCV+TGC) by employing a thermodynamic method.In addition,based on Visual Basic program,a platform for analyzing the performance of both cycles was developed.It has been found that under the identical contrast conditions,the average performance of TSCV+TGC+IHX is 5%~10% higher than that of TSCV+TGC and the optimum intermediate pressure of TSCV+TGC+IHX is about 5%~15% lower than that of TSCV+TGC.The research findings can serve as basic data for development of high efficiency and energy-saving CO2 heat pump hot water heater products operating in trans-critical cycles.
