“…On the basis of obtained experimental information for the enthalpy of the ROS R600a−WF 15A, using information on the thermodynamic properties for the ROS R600a−WF 15A (vapor pressure) reported in Nichenko and the methodology reported in Zhelezny et al, we developed pressure−enthalpy ( P − H ) and concentration−enthalpy diagrams ( w − H ) for the real working fluid. The examples of P − H and w − H diagrams are shown in Figures and .…”

“…The mineral compressor oil WF series is used to lubricate small hermetically sealed compressors, in refrigerators, especially those operating with the refrigerant R600a. That is why correct information on thermal and caloric properties of the refrigerant−oil solution (ROS) which circulates in the refrigerant system has considerable scientific and industrial interest. − …”

This paper reports new experimental data for the specific enthalpy of the solution of isobutane (refrigerant R600a, CH(CH 3 ) 2 -CH 3 , CAS Registry No. 75-28-5) with mineral naphthenic compressor oil WF 15A. The experimental data were obtained in the temperature range from (273 to 355) K by a mixing method realized in an ice calorimeter. The behavior of the temperature and weight fraction dependencies of the enthalpy for the refrigerant-oil solution (ROS) of R600a and mineral compressor oil WF 15A have been examined.

“…An application of the "classical" (P-h) diagrams for the pure refrigerants does not allow taking into account the influence of compressor oil admixtures to the efficiency of the compressor system and intensity of the heat transfer in evaporator. Pressure-enthalpy (P-h) diagrams for RWF can be developed only by using information for the thermodynamic properties of the RWF [4,13]. Creation of these diagrams should be performed for various concentrations x g of the compressor oil flow circulating around the contour (x g is the oil mass concentration before throttling device).…”

В работе проведен анализ и обобщение результатов исследования теплофизических свойств растворов хладагент/компрессорное масло. Рассмотрены методические аспекты экспериментального исследования термических свойств реальных рабочих тел для парокомпрессионных холодильных машин и общие принципы прогнозирования термодинамических свойств подобных систем. Показано, что примеси компрессорного масла в хладагенте значительно снижают параметры эффективности компрессорной системы. Рассмотрен вопрос селективной растворимости многокомпонентных хладагентов в компрессорных маслах. Ключевые слова: Раствор хладагент/компрессорное масло -Термические свойства -Параметры эффективности -Селективная растворимость.

“…The experimental data are suffi ciently described by proposed few-constant equations. Proposed results can be applied for further developing diagrams of pressure-enthalpy for refrigerant oil solutions [15,16], designing refrigerating compressors and heat exchangers and increasing an energy effi ciency of the refrigeration plant. Finally, experimental data obtained can be useful for additional developing different thermodynamic models such as equation of state, etc.…”

In the present study, an accurate experimental information for the widely used commercial refrigerating compressor oils ONF 46, ACD 100 FY, Azmol, FR 32, XC 15, XC 40 and WF 15A is presented. Experimental data on the capillary constant, surface tension, density, refractive index and kinematic viscosity at the temperature range from 293 to 353 K for seven commercial compressor oils are reported. In addition, the experimental data on the isobaric heat capacity at temperature range from 288 to 393 K, the vapor pressure at liquid-saturated curve and average molecular weight for four commercial compressor oils are fi rstly presented in the paper. The data obtained are fi tted by few-constant correlations. Based on results obtained, the values of pseudocritical temperature for the compressor oils have been determined.
