HFO-1234yf与HFC-134a比较分析 朱正园,柳建华,张良,贺航,康盈,张慧晨,周日海 (上海理工大学制冷技术研究所,上海200093) 摘要:总结了HFO-1234yf的最新研究成果,对比分析了HFO-1234yf和HFC-134a的热物性参数及实验表 现,结果表明两者的热物性参数及实验表现非常相似,HFO-1234yf是较好的替代制冷剂之一。为了更好的...
The test results show that at the lowest mass flux, liquid thermal\nconductivity dominate the heat transfer mechanism and therefore the heat transfer coefficients of\nHFC-134a are that those of HFO-1234yf. For higher mass fluxes, in addition to the liquid thermal\nconductivity, liquid and vap...
HFO-1234yf可替代第三代汽车空调制冷剂HFC-134a(Gwp值为1430),即每使用1吨HFC-134a相当于排放二氧化碳约1430吨,第四代实现替代后,每吨相当于减排二氧化碳约1400吨。HFO-1234yf作为HFC-134a替代产品,具有制冷能效高、安全性高特点,是汽车空调行业节能减排综合性能的优选～利好地球～利好全人类!!!重大利好!!!
为分析在汽车空调系统中使用HFO-1234yf替代HFC-134a的可行性,建立了电动汽车空调制冷系统一维仿真模型,将原HFC-134a系统优化为带回热管的HFO-1234yf系统,并在不同工况下对两种系统的制冷性能进行了对比分析.仿真结果表明:回热管可以使HFO-1234yf系统在制冷量和COP上分别提升10%和9.2%;在部分工况下,带有回热管的HFO...
A mathematical computational model has been developed for calculating Coefficient of performance (COP), exergetic efficiency, exergy destruction and efficiency defects for HFO-1234yf, HFO-1234ze and HFC-134a.During the investigation, condenser temperature is kept at 313K and evaporator temperature is ...
HFO-1234yf/HFC-134a mixturesAn experimental study of the pressure–volume–temperature-composition (PVTx) properties in the gas phase for binary mixtures of 2,3,3,3-tetrafluoropropene (HFO-1234yf)+ 1,1,1,2-tetrafluoroethane (HFC-134a) was conducted in the range of temperatures from 298.58 ...
HFC-134aSurface tensionMicrochannelRefrigerant HFO-1234yf has similar properties to HFC-134a but much lower GWP value. It is possible to replace HFC-134a by directly drop into the air-condition systems and expected to be an appropriate replacement for these systems. Microchannel heat exchangers have...
