摘要
提出了新型制冷剂R407C、R410A及R227热力性质的快速计算方法,并对其特性分析比较。借鉴Cleland制冷剂热力性质简化计算公式,拟合出热力性质快速计算方程的系数,并从运行效率、经济性和安全性等角度来研究新型制冷剂的特性。结果在制冷空调的常用温度范围内,检验拟合系数的计算精度与Cleland给出的其他制冷剂拟合精度相仿,在某些性能上新型制冷剂要优于被替代物。此快速计算方法可应用于装置的仿真和优化计算及装置或过程的实时控制。R407C、R410A能很好作为R22的替代物,R227是一种很有前途的制冷剂,很有可能作为混合物的一种阻燃组份用于HCFC的混合替代物中,或作为热泵中CFC的纯质替代物使用。
Through comparing the thermodynamic properties of new refrigerant of R407C, R410A and R227,propose an optimization and simulation method. By using the simplified calculation formula of refrigerant of Cleland,draw the coefficient of quick calculation equation of thermodynamic properties,and study the characteristics of the new refrigerant from various angles such as operating efficiency, economy and security.result in the commonly used temperature range of refrigerating air-conditioning, the calculation accuracy of fitting coefficient is similar to fitting precision of other refrigerants which Cleland gives. In some performance,the new refrigerant is superior to the alternatives.conclusion This quick calculation method can be applied to simulation and optimization calculation of the device and the device or process real-time control. R407C, R410A can replace R22 very well, R227 is a promising refrigerant,it is possiblily used in the mixed HCFC alternatives as one flame-retardant component of the mixture,or as pure alternative of the CFC in the heat pump.
