The substitutability of R1234yf refrigerant was analyzed,and effective measures were taken to improve its refrigeration performance. 制冷劑作为空调系统的工作介质,理想的制冷剂不仅要有优良的热物理性质及安全性,也要有较好的环境友好性。R134a是目前常用的汽车空调制冷剂,其GWP(Global Warming Potential)为1430,...
［摘 要］：为研究制冷剂Ｒ１２３４ｙｆ替代Ｒ１３４ａ后对冰箱压缩机性能的影响，以及两者在冰箱压缩机使用上的通用性，分别选取标称使用Ｒ１２３４ｙｆ和标称使用Ｒ１３４ａ制冷剂的冰箱压缩机各一台，在同一测试系统下分别使用Ｒ１２３４ｙｆ和Ｒ１３４ａ制冷剂对２台压缩机进行不同工况的测试，测试方法遵循标准Ｇ...
R134a and R410a,respectively;the power consumptionof high-pressure compressor is 21% and 22% lower than R134a and R410a,respectively.To some extent,R1234yf refrigerant canbe used as a substitute for R134a and R410a.Keywords:Two-stage compression,COP,R134a,R410a,R1234yf1 引言随着《关于...
Made in the US, Opteon™ YF (R-1234yf) offers comparable thermodynamic performance to R-134a and similar energy efficiency and capacity—with the benefit of zero ozone depletion potential (ODP) and very low global warming potential (GWP). The AIM (American Innovation and Manufacturing) Act ...
【Portable】: R1234YF to R134A conversion, easier and more convenient to disassemble and install, Small and compact, easy for you to hold and grasp. 【Apply】: Used for A/C Refrigerant, used to connect female and male adapters of different diameters, suitable for pipes connection, check, ...
R1234yf制冷剂,四氟丙烯,作为单一工质的制冷剂,具有优异的环境参数,GWP=4,ODP=0,寿命期气候性能(LCCP)低于R134a,大气分解物与 R134a 相同。而且其系统性能优于R134a。 若选用R1234yf替代R134a制冷剂,则汽车生产商就可以继续沿用原车载空调(Mobile Air-Conditioning,MAC)系统。 所以R1234yf被认为较具潜力的新一...
由于内设滤层,因此对挥发性酒精(居住环境常见干扰气体)灵敏度很低,体现出对不易燃制冷剂的高选择性。由于敏感素子体积很小,TGS2630的加热器电流仅需56mA,外壳采用标准的TO-5金属封装。 在新型合成的人工制冷剂中,近自然工质或自然工质将是未来替代制冷剂的发展主流。将现有的制冷量及COP较理想的制冷剂(如R134a)...
