Determination of the Thermodynamic Properties of Refrigerant-Oil Mixtures
نویسندگان
چکیده
The errors associated with therModynamic performance calculations are discussed with particular reference to systems with a high oil charge. It is shown that calculations made using published refrigerant data can be very misleading as no account is taken of the oil solubility effects. Pressure-enthalpy charts are presented for refrigerant R12 oil mixtures, for a range of oil concentrations. The effect that the existence of this mixture has on evaporator performance and COP of a refrigeration or heat pump system is discussed and some results are compared with the pure refrigerant cycle normally considered.

Interactions of Hydrofluorocarbons and Polyolester Lubricants
A variety of hydrofluorocarbon (HFC) compounds, both as pure substances and mixtures, are being developed as alternative refrigerants to replace the exsting chlorofluorocarbons and hydrofluorocarbons which have been linked to stratospheric ozone depletion. The use ofHFC's in refrigeration systems will require new lubricants, and polyolesters are being widely promoted as the lubricant of choice ...
متن کاملSemi Empirical Calculation of Intermolecular Potentials and Transport Properties of Some Binary and Ternary Industrial Refrigerant Mixtures
In this study the intermolecular potential energies of some environment-friendly industrial HFC refrigerants were obtained through the inversion method which is based on the corresponding states principle. These potentials were later employed in calculation of transport properties (viscosity, diffusion, thermal conductivity and thermal diffusion factor) of some binary and ternary refrigerant mi...
متن کاملTransport Properties of Refrigerant Mixtures: Thermal Conductivity
In the present work, the integral equations method is used to calculate transport properties of polar fluids. For this goal, we use the Stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as R125+R134a, R125+R32, R125+R152a, R134a+R32, R152a+R32, R134a+R143a, and R125+R143a. We solve numerically the Ornstein-Zernike (OZ) equation usin...

In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...
متن کاملPrediction of Thermodynamic Properties of Refrigerants in the Superheated Ragion
This paper demonstrates the capabilities of the PFGC-MES equation of state (EOS) for calculating the thermodynamic properties in the superheated region for pure refrigerants. In addition the ability of this EOS is also tested for predicting the VLE behavior of binary mixtures. For pure compounds several properties in the superheated region are predicted. The calculated results and the experimen...
